  Show 1487: Hair Loss and Nail Problems: A Dermatologist’s Guide to What Actually Works 18.09.2026 1h 12min

  Do you worry that your hair is thinning? You may wonder what treatments could make a real difference. After all, you wouldn’t want to spend money on something that has no chance of helping. Many people also have concerns about their nails. Perhaps they are ridged, or loose, or too thick. Could that be due to nail fungus, or might it have another cause? Most importantly, what could you do about it? In this episode, you’ll get a dermatologist’s guide to what actually works. At The People’s Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

What Actually Works for Hair and Nail Problems Dr. Chris Adigun practices both general and cosmetic dermatology. We wanted to ask her about nail problems in particular because they are very common and she maintains a specialty in treating them. We asked her about the most common nail problems she sees, and she named simple onycholysis (pronounced Oh-nick-oh-LYE-sis). In this condition, the nail begins to lift away from the nail bed. You can identify it because the white area at the fingertip becomes much more extensive than usual. Usually, this is due to exposure to acids such as citrus juices or cleaning solutions. Having your hands in and out of irritants or even water (with or without soap) could lead to onycholysis. An overactive thyroid gland could also lead to onycholysis. To prevent it, try to avoid putting your hands into that sort of liquid. If you must do so, use gloves. And of course, a good hand cream to bolster the skin barrier is a very good idea. If these approaches don’t do the trick, especially if there are other symptoms, the doctor may want to test for thyroid function. Another common problem is allergic contact dermatitis. This could be caused by some of the same irritating substances responsible for onycholysis, but cosmetics are common culprits here. Nail polish and remover, especially nail polish remover, can cause nail problems for some people. If you are one of them, what actually works best might mean finding a less irritating product or, even better, leaving the nails unadorned. White Spots on Nails Many people have noticed white spots on their nails. We asked Dr. Adigun what causes these, and she replied that usually they are not worrisome. If you bang your fingertip, as you might if you slammed it in a door or a drawer, the trauma may show up several weeks later as a white spot. (More serious trauma could show up as a dark spot due to blood pooling under the nail; we discussed that with podiatrist Jane Anderson here,  but not with Dr. Adigun.) What About Ridges on the Nails? Nail ridges are very common, and the ones that run lengthwise along the same axis as the finger are due to aging. Just as our skin develops wrinkles, so do our nails. Consequently, there are no effective treatments. Nail ridges in children are a different story. They might show up as nails having the texture of sandpaper, or they could be horizontal ridges. Such nails should be seen by a physician, as they could signal an inflammatory condition called lichen planus or even an early sign of psoriasis. While we don’t have cures for these conditions, there are effective medications to manage them. Hangnails and Cuticle Problems Are you surprised that dermatologists have a fancy term to describe cuticle problems and other trouble affecting the skin around the nail? They call it paronychia (PEAR-oh-nick-ee-ya). If it is caused by an infection, it might be treated with an antimicrobial compound. The best preventative is not to pull, bite or clip off hangnails or rough spots in the cuticles, the skin near the nails. Instead, moisturize and possibly cover the spot with a bandage to remove the temptation while it softens and heals. Instant glue is another simple remedy that really works for hangnails. Treating Nail Fungus When the nails are thick, ugly and hard to trim, often people blame nail fungus. But surprisingly, it isn’t always the culprit. Mechanical trauma can also create thick nails that are hard to cut. If the nail is thick because it is on a hammer toe so it bumps against the insole of the shoe, antifungal treatment won’t help. If a healthcare professional addresses it when it first appears, it may be treatable, but once the body has grown accustomed to producing that thick nail, there may be no effective treatment. Some nail infections are bacterial as well as fungal. Both may show up together, or the infection may be one or the other. A dermatologist has techniques for diagnosing whether the problem is due to a fungus or to bacteria such as Corynebacterium. Different types of antimicrobial medicines are effective for these infections. Athlete’s foot also needs a real diagnosis, since it too might be bacterial rather than fungal in nature. OTC athlete’s foot medicines target fungal infections. Handling Hair Loss Both men and women experience hair thinning, and no one is pleased about it. The patterns differ, with men noticing a receding hairline and less hair on their temples. Women’s hair loss tends to form a Christmas-tree pattern, with the tip of the tree right behind the hairline and the base spreading out over the crown of the head. Women are also prone to hair loss after giving birth to a baby. However, while that may be alarming in the moment, it often corrects itself without treatment over the following months. Hormonal Treatments for Hair Loss With men, scientists have identified testosterone metabolites as contributing factors. Drugs such as finasteride (Propecia) or dutasteride block those metabolites and help men regrow hair. Dr. Adigun has begun using these compounds in women who are beyond childbearing. (They are off limits for a person who might become pregnant because they could interfere with the normal development of genitals in a fetus.) A different hormonal treatment for hair loss is spironolactone. Dermatologists have long used it to treat female pattern hair loss. A review found that spironolactone is an effective and safe treatment option for hair loss” (Cureus, Aug. 16, 2023). Besides boosting scalp hair growth, however, it can also cause itchy scalp, facial hair growth and menstrual problems. Another approach that actually works for hair loss is minoxidil (Rogaine). Most people are familiar with this as a topical product to be applied twice daily. That might get old after a while. Also, some people react to the product with contact dermatitis, irritation or itching. Low-dose oral minoxidil seems to work as well as topical minoxidil without the irritation. Another possible option which is better than placebo but not as potent as full strength topical minoxidil is rosemary oil. It is less likely to cause itching, however. This Week’s Guest Chris G. Adigun, MD, FAAD, is a board-certified dermatologist and the President and Medical Director of the Dermatology & Laser Center of Chapel Hill, which she founded in 2016. Dr. Adigun practices both general and cosmetic dermatology, with a strong emphasis on minimally invasive treatments that deliver natural, impactful results. She has devoted much of her career to increasing public awareness of skin cancer and the harmful effects of UV exposure—both medical and cosmetic—and maintains an academic specialty in nail disorders.

  Show 1486: Sprains, Strains and Tears: The New Science of Healing Faster 10.09.2026 1h 5min

  For years, anyone who sprained an ankle or twisted a knee got some standard advice: ice it, rest it, wrap it with compression tape and keep it elevated. The acronym for Rest, Ice, Compress and Elevate is RICE. New research shows that following this advice alleviates the pain from the injury in the short term, but it may actually slow healing. What can help you in healing faster from this type of problem? You can hear it directly from a scientist applying cutting-edge research with tendons and rats to getting NBA players back on the court sooner. At The People’s Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment. How You Can Listen You could listen through your local public radio station or get the live stream at 7 am EST on Saturday, September 12, 2026, through your computer or smart phone (wunc.org).  Here is a link so you can find which stations carry our broadcast.

You can subscribe through your favorite podcast provider, download the mp3 using the link at the bottom of the page, or listen to the audio stream on this post starting on Sept. 14, 2026. We will also be putting up a YouTube video podcast so you can watch our guest do some demonstrating. Healing Faster from Injuries Sports medicine expert Dr. Gabe Mirkin coined the acronym RICE in the 1970s. At the time, many physicians and physical therapists embraced this approach to treating injuries. It helped reduce the pain in the immediate term, and it doesn’t seem to do any harm over the longer term. It can take quite a while to heal damaged tendons and ligaments, however. Sometimes, that takes even longer than for broken bones to knit. Eventually, Dr. Mirkin reversed his RICE recommendation. But very few professionals took note. Is there a happy medium between applying RICE and toughing it out by trying to walk a sprained ankle off? Our guest on this episode has been studying the topic of healing faster from injuries and has some concrete advice to offer. Trying to Fool Mother Nature Many of the precautions that amateur athletes take are designed to undermine the body’s inflammatory response. Yet acute inflammation is exactly how the body tries to heal itself from injury. Ice and ibuprofen are anti-inflammatory, so taking ibuprofen before exercise or icing a sore knee afterwards might be counterproductive. What Is a Better Approach to Healing Faster? According to Dr. Keith Baar, immobilizing a joint (“rest”) leads quickly to loss of muscle and force. When he put rats on bed rest (listen to learn how), they lost strength rapidly. On the other hand, moving a joint gently helps to reduce swelling by pumping fluid out. This, in turn, is an early step in healing faster. How do you move a joint gently? Dr. Baar has developed his own acronym: 3LD isometrics. How Do You Practice 3LD Isometrics? First of all, what does 3LD even mean? It stands for low-load, long-duration isometrics. During isometric exercise, instead of moving a muscle quickly, you hold it in position until it fatigues. Physical therapists recommend isometrics, such as planks or wall squats, to strengthen the muscles around joints. In low-load long-duration exercises, you provide some support so you are not putting your entire body weight on the joint. In other words, you lessen the load. Rather than moving quickly through the motion, you find the point at which you can feel the tension in the muscle but it doesn’t actually hurt. Dr. Baar describes this as ooh instead of ouch. Then you hold that position (with the support, remember) for 30 seconds or so. This is a relatively long duration. Healing Faster from Sports Injuries Dr. Baar describes how he helped his nephew, a college-team football linebacker, heal an injured shoulder. Sports injuries are not the only joint problems that could benefit from healing faster with 3LD isometrics. Other common complaints are carpal tunnel syndrome in the wrist or plantar fasciitis in the foot. Changing the Culture of Treating Injury Dr. Baar describes his work with a rugby player who injured his hamstring tendon and was able to resume playing much earlier than the surgeon initially anticipated. Baar’s team has also worked with a basketball player who ruptured an Achilles tendon last year. Healing faster with 3LD isometric work got him back on the court last year–the only NBA player with such an injury to manage that. As elite athletes learn the advantages of 3LD isometrics, physical therapists will begin offering it to ordinary people who simply want to resume their usual activities sooner. This Week’s Guest Keith Baar, PhD, is a professor of molecular exercise physiology at the University of California, Davis who leads the Functional Molecular Biology Laboratory. Dr. Baar is a leading expert in musculoskeletal health, studying how muscles, tendons, and ligaments respond to mechanical loading and nutrition.

  Show 1421: Is Lp(a) the Heart Risk No One Talks About? (Archive) 03.09.2026 1h 6min

  This week, we get in-depth information on Lp(a), the heart risk no one talks about. You have heard of cholesterol, and you may even know what your cholesterol level is. The compound lipoprotein a may be equally dangerous when it is elevated, but you have probably heard very little about it. At The People’s Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment. How You Can Listen You could listen through your local public radio station on Sept. 5, 2026, or get the live stream at 7 am EDT on your computer or smart phone (wunc.org). Here is a link so you can find which stations carry our broadcast. If you can’t listen to the broadcast, you may wish to hear the podcast later. You can subscribe through your favorite podcast provider, download the mp3 using the link at the bottom of the page, or listen to the stream on this post starting on Sept. 7, 2026. What Is Lp(a)? Lipoprotein a, or L-P-little a for short, circulates in the bloodstream, where it picks up and carries cholesterol and oxidized phospholipids. Scientists believe that blood levels are determined mostly by genetics and change very little over the course of our lives. Roughly 20 percent of people have high levels of Lp(a), above 30 ng/dL or 75 nmol/L. The two different figures are because tests use different units to measure the blood concentration, either nanograms per deciliter or nanomols per liter. While we don’t know if Lp(a) has or perhaps once had some important functions, we do know that elevated levels of this chemical is associated with heart disease. People with higher levels are more likely to suffer blood clots and inflammation. That puts them at risk for heart attacks or even strokes. So why hasn’t your doctor ordered a blood test to learn your level? Is Lp(a) the Heart Risk Doctors Can’t Treat? Perhaps doctors have been reluctant to measure or discuss lipoprotein a because they don’t have good interventions. That is beginning to change with the development of antisense oligonucleotides, a new category of prescription drugs that can cut levels sharply. The FDA has not yet approved any of these new medications, though. The first of these, pelacarsen, is still in Phase 3 trials needed before the agency can consider the evidence. However, it can bring down lipoprotein a by an estimated 80 percent. Cardiologists’ favorite drugs, statins, do not help Lp(a) levels. In fact, Lp(a) the heart risk rises when people are taking statins to lower their cholesterol. Other cholesterol-lowering drugs such as evolocumab (Repatha) and alirocumab (Praluent) can bring Lp(a) levels down modestly. One really old cholesterol-lowering drug, high-dose niacin, also helps moderate Lp(a). Some people do not tolerate it, however, as it can cause very uncomfortable flushing. So far as we know, no scientists have run studies to see whether niacin reduces the risk of heart attacks and other complications because of its effects on Lp(a). Other Complications of Lp(a): Our guest, Dr. Sam Tsimikas, is among the country’s leading experts on lipoprotein a. We asked him whether Lp(a) the heart risk factor causes other problems as well. Dr. Tsimikas described heart failure, potentially resulting from a heart attack, as well as peripheral artery disease (PAD), which can make it painful to walk. Lp(a) seems to cause plaque in arteries throughout the body. As a result, it can increase the chance of a stroke. In addition, it contributes to calcification of the heart valves. This condition interferes with their ability to function properly. What Can We Do If Lp(a) Is Too High? Dr. Tsimikas runs a unique clinic for cardiology patients with high levels of Lp(a). We asked him how he helps them. One approach is to collect additional information about their level of risk. A coronary calcium score can be a useful indicator. If it is high, he and his patients work to control all the potential risk factors that they can. He discusses the potential benefit of aspirin with them. Because Lp(a) the heart risk factor increases the chance of dangerous blood clots, the anti-clotting activity of aspirin can sometimes be helpful. Offering dietary advice can be tricky if a patient has high cholesterol as well as elevated Lp(a), since the ideal diets for each are nearly opposite each other. A ketogenic diet tends to raise LDL cholesterol, for example, while it may modestly lower Lp(a). We think by the end of this episode, you’ll join us in hoping that scientists can learn a lot more about Lp(a) in the next few years.

  Show 1485: What Are We Still Getting Wrong About ADHD? 27.08.2026 1h 22min

  A new school year is about to start in many parts of the country. Going back to school can be exciting, but some students may dread it. Perhaps they are struggling with attention deficit hyperactivity disorder, abbreviated ADHD. How can you recognize the symptoms of this problem? What are the most common misconceptions? In short, what are we still getting wrong about ADHD? When we talk about distractibility, trouble missing deadlines, forgetting where you left your keys, it is easy to relate. Likewise, when we look at kids with wiggles and short attention spans, do we see a child with ADHD or just a normal youngster? What constitutes ADHD? Does everyone have it, or is it an all-or-nothing condition? Expert John Mitchell explains that many people have some symptoms from time to time, but once a person is suffering from enough that it is affecting their ability to function, that is when a yes-or-no ADHD diagnosis is made. At The People’s Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment. How You Can Listen You could listen through your local public radio station or get the live stream at 7 am EST on Saturday, August 29, 2026, through your computer or smart phone (wunc.org). Here is a link so you can find which stations carry our broadcast. If you can’t listen to the broadcast, you may wish to hear the podcast later. You can subscribe through your favorite podcast provider, download the mp3 using the link at the bottom of the page, or listen to the stream on this post starting on August 31, 2026. What We Get Wrong About ADHD One of the most common misconceptions about ADHD is that it primarily affects little boys who can’t sit still. While hyperactivity can certainly make a parent or a teacher uncomfortable, the inattention aspect of ADHD could be more disabling in many instances. Moreover, girls too may suffer with ADHD. Though they are less likely to be hyperactive, they can often have difficulty focusing. Another popular myth about ADHD is that it is a pediatric condition. People think kids grow out of it. What we are beginning to see with more research into ADHD is that some people learn effective coping skills they can use as adults. Nonetheless, many older people who were not recognized as having ADHD when they were children may discover that their impulsivity and lack of follow-through, accompanied by anxiety, depression or migraines perhaps, could be a manifestation of this disorder. Failing to recognize the suffering of neurodivergent adults is another thing we get wrong about ADHD. How Do You Treat ADHD? A third misunderstanding about ADHD is that prescribing a stimulant medication is the only treatment necessary. While drugs such as methylphenidate (Concerta, Ritalin) or mixed amphetamines (Adderall) can be really helpful, there is a saying in the ADHD community: the pills don’t teach skills. They do allow a person to focus well enough to learn some new skills they will need. Nonpharmacological approaches are important in conjunction with prescription medicine. However, adolescents with ADHD are much less likely to turn to drugs of abuse if they are taking properly prescribed stimulant medicines in the context of a thoughtful treatment plan. What Is the Role of Emotional Regulation in ADHD? Pediatric ADHD expert Paul Rosen describes another assumption that we can get wrong about ADHD. A child may appear to be doing fine, bringing home As, getting along well in school. But he describes “duck syndrome,” in which you see a duck gliding along the surface of the water. The motion looks effortless, but the duck is paddling like crazy. If it gets into an eddy or a current that’s too strong, it can’t keep up. These students are working much harder than is apparent and at some point, they encounter demands they can’t meet. How will they respond to that frustration? Trouble with emotional regulation is not always part of the ADHD picture, but it isn’t unusual, either. Some kids with ADHD respond pretty much as other youngsters do, but some seem like a super bouncy ball. Their emotions go very high and very low quickly, but they bounce back quickly as well. Still other children may be more like volcanoes. When faced with frustration, they explode, and it may take them many hours to return to baseline. Focusing on Warm and Fuzzies Parents sometimes assume that impulsive or explosive behavior is willful, but that is another thing we often get wrong about ADHD. Most of the time, such behavior is emotional. The child wants to be a “good kid” but may not know how to deal with these extreme emotions. Dr. Rosen recommends unconditional positive attention. He suggests that when parents tuck their ADHD children into bed at night, they appreciate one thing the child has done that day and one aspect of the child, separate from the behavior, that is wonderful. This kind of affirmation can help a youngster keep striving for the skills they will need. (In fact, it sounds like a helpful idea for any parent and child, regardless of whether either of them has ADHD.) This Week’s Guests John T. Mitchell, PhD Dr. John Mitchell is an Associate Professor in the Department of Psychiatry and Behavioral Sciences at Duke University. His research and clinical work are focused on ADHD across the lifespan. He has published peer-reviewed articles and chapters on longitudinal outcomes and the treatment of ADHD, as well as recently co-authoring Mindfulness for Adult ADHD: A Clinician’s Guide.

In this week’s podcast, Dr. Mitchell explains why people without ADHD react so differently to stimulant medication.

  Show 1484: Change Your Diet, Heal Your Mind 21.08.2026 1h 15min

  Do you suffer with anxiety, depression, or another mental illness? Millions of people do. The usual treatment is a prescription medication. If that doesn’t work, the healthcare provider may offer a different one. Diet is certainly not the first topic on the provider’s mind. But what if, in addition to appropriate pharmacological treatment, you were able to nourish, protect and energize your brain with your diet? Our guest offers evidence that you can heal your mind with a ketogenic approach to eating. We need to acknowledge that this approach is quite different from the plant-rich eating pattern advocated by last week’s guest, Dr. Will Bulsiewicz. Humans around the world have adopted a wide range of dietary regimens that support health. Listen to Dr. Georgia Ede explain why she thinks a paleo or ketogenic diet is helpful for bolstering brain health. At The People’s Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

Can You Heal Your Brain with Food? We live in stressful times. More than 50 million Americans take prescription antidepressants, and millions more are on anti-anxiety medication. Unfortunately, while these drugs can be life savers, they don’t always work as well as we would like. In some cases, antidepressants are only about 10 percent more effective than a placebo. Dr. Georgia Ede is a psychiatrist who began her investigation into how food affects mental health serendipitously. She was experimenting with her own diet to address some physical health issues. She used a food and symptom journal to discover the best dietary choices for her own health. To her surprise, the “upside-down” diet that helped her feel better physically also improved her sleep and her ability to focus. She started looking into evidence that a paleo or ketogenic diet could benefit people with mental health challenges. What Is Metabolic Psychiatry? There is evidence that people consuming unhealthy diets full of fast food or ultra-processed products are more susceptible to symptoms of anxiety (Nutrition Neuroscience, May 19, 2026). On the other hand, people participating in a supervised weight-loss program using either a low-carbohydrate ketogenic diet or a low-fat diet reported improvements in mood (Obesity, Jan. 2007). Those on the ketogenic (Atkins) diet reported less hunger and fewer unpleasant symptoms. Researchers have also tested a ketogenic diet in people with schizophrenia or bipolar disorder (Psychiatry Research, May 2024).  These volunteers also had metabolic disorders, including obesity, which is often an unwanted effect of the ant-psychotic drugs they take to treat their condition. This four-month pilot study saw participants lose weight, reduce insulin resistance and lower their triglycerides. Even more impressive, they had a 32 percent reduction in the Brief Psychiatric Rating Scale. They also reported better sleep and improved life satisfaction. You may find this recent article from National Geographic of interest: https://www.nationalgeographic.com/health/article/metabolic-psychiatry-keto-diet-brain-science. Unfortunately, it might be behind a paywall. How Does Food Affect Our Brains? Most of our body tissues are accustomed to getting energy from glucose, with the help of insulin. However, years of exposure to high levels of these compounds often makes the tissues less sensitive to the effects of insulin. The consequence is that the body–and therefore also the brain–is flooded with high levels of glucose. This exposure can result in the formation of advanced glycation end products in the brain, which can be harmful. The brain evolved to use either glucose or a flexible mix of glucose and ketones. These are the result of burning fat rather than sugar. A paleo diet will naturally provide more ketones and less glucose. Dr. Ede and colleagues have found that a ketogenic diet can be very helpful even for people with relatively serious mental problems. In one study (which was not placebo-controlled), patients hospitalized with severe persistent mental illness were given a ketogenic diet. Most did well and had significant improvements in their depression and psychosis symptoms (Frontiers in Psychiatry, July 6, 2022). Is Ketosis Dangerous? Ketosis itself simply means that you are burning fat as fuel rather than sugar. This can be achieved by following a diet that is high in animal fat, with moderate amounts of animal protein and low amounts of carbohydrate derived from plant foods. Ketosis is not inherently dangerous. However, Dr. Ede urges anyone who wants to heal their brain with diet to ask a healthcare provider to monitor and supervise the process. Prescription drug doses may require adjustment, and people may need support as they adopt a paleo or ketogenic diet. That is why this is not a do-it-yourself approach. Is Coconut Oil Helpful to Heal Your Brain? Dr. Ede described the benefits of medium-chain fatty acids produced in digesting fat. You may recall a video from a few years back in which a doctor described helping her husband recover from Alzheimer disease, at least partially, by giving him coconut oil. Some researchers consider Alzheimer disease to be a form of diabetes because the AD brain does not metabolize sugar effectively. Dr. Ede suggested that the benefits may be real, but getting medium-chain fatty acids from the diet rather than be taking coconut oil might be preferable. After Dr. Ede told us about Fran, who overcame significant memory problems by changing to a ketogenic diet, we hope there will be trials on this. Future Trials on Diet to Heal Your Brain Dietary trials are notoriously difficult to conduct. People often don’t stick to the prescribed diet, and it can be difficult to find an appropriate placebo for comparison. Nonetheless, Dr. Ede is looking forward to results from a large trial of the keto diet for people with schizophrenia or bipolar disorder. This study is being conducted in Australia. This Week’s Guest Dr. Georgia Ede is a globally recognized expert in nutritional and metabolic psychiatry. Her 25+ years of clinical experience include 7 years at Harvard University, where she was the first psychiatrist to offer nutrition-based approaches to mental health conditions. Dr. Ede co-authored the first inpatient study of the ketogenic diet for serious mental illness, developed the first medically accredited course in ketogenic diets for mental health, and is a recipient of the Baszucki Metabolic Mind Award. Current research collaborations include pilot studies in pediatric bipolar disorder, adult ADHD, and PTSD. Her internationally bestselling book Change Your Diet, Change Your Mind: A Powerful Plan to Improve Mood, Overcome Anxiety, and Protect Memory for a Lifetime of Optimal Mental Health is being translated into 11 languages and is recommended by the New York Times Book Review.

  Show 1483: The Gut Immune Solution 13.08.2026 1h 10min

  When you decide to grab a bite to eat, do you think about how to feed your gut microbes? Most of us don’t. Even if we did, their only means of stating their preferences is somewhat after the fact. Do you end up feeling less than well? Perhaps the denizens of your gut aren’t happy. In this episode, we consider how to support your microbiota and whether that can reduce the inflammation that seems to accompany modern life. At The People’s Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

Feed Your Gut Right to Fight Inflammation Dr. Will Bulsiewicz is a gastroenterologist who urges all of us to focus on a healthful fiber-rich plant-strong diet to maintain our microbiome in good shape. He has described his own evolution from a busy medical student relying heavily on processed food products to a whole-food plant-based enthusiast. Eating a wide variety of plants is one of the easiest ways to make sure we are getting the nutrients our gut microbes need. Why are the trillions of microbes in our large intestine so important? Dr. Bulsiewicz (aka Dr. B.) shares the story of a patient who was overwhelmed by a serious C. diff infection. A course of clindamycin for a skin infection had decimated her normal microbiome and left an open field for C. diff to flourish. Instead of treating her with surgery and even more potent antibiotics, Dr. B. and his colleagues utilized a fecal transplant. She got poop from a healthy person into her colon and left the hospital a few days later in good health herself. What Is the Link Between the Microbiome and the Immune System? Inflammation is one of the primary signs that the immune system has gone into action to fight off a perceived foe. There is a close relationship between the gut microbes, the gut barrier and the cells of the immune system. Between 70 and 80 percent of immune system cells are present in the gut (Nutrients, March 9, 2021).  There is just one layer of cells in the gut barrier, firmly attached to each other through tight junctions. If those tight junctions break down, pathogens and toxins can get from the gut into the bloodstream and activate the immune system into creating inflammation Medicines That Harm the Intestinal Barrier Diets that are high in salt have a negative impact on the integrity of the intestinal barrier (Nutrients, Nov. 25, 2025). In fact, a diet high in salt can reduce the number of Lactobacilli in the gut by 90%. This also affects the permeability of the gut barrier, which can contribute to auto-immune conditions. When we asked about inflammatory bowel disorders such as Crohn disease or ulcerative colitis, Dr. B. told us he thinks it’s a mistake to classify them as auto-immune conditions. Instead, he suggests we should consider these conditions as due to the immune system rejecting the microbiome. Some of them might be initiated and perpetuated by failures in the gut barrier that allow certain organisms or their toxins into systemic circulation. A number of medications can also harm it, most notably the nonsteroidal anti-inflammatory drugs (NSAIDs). Agents like ibuprofen, naproxen, celecoxib and meloxicam may disrupt the tight junctions that keep the intestinal barrier intact (Gastroenterology, Feb. 2018).  In some cases, they may also upset the balance of microbes. Four Keys to an Anti-Inflammatory Diet There are several different dietary patterns that allow you to feed your gut and fight inflammation. Good evidence supports a DASH diet, a Mediterranean diet, pescatarian, flexitarian, vegetarian and some vegan diets. We asked Dr. B. to summarize the four features healthful eating patterns share. They include adequate fiber, plenty of polyphenols, healthy fat and fermented foods (think of sauerkraut or kimchi). Fiber and Flatulence One drawback of a high-fiber diet is that when microbes in the colon ferment the fiber we can’t digest, they produce gases. It has to go somewhere, or it will cause sensations of cramping and bloating. Consequently, fiber is often associated with flatulence. Dr. B. suggests that there may be more gas, and it may be loud, but it shouldn’t be stinky. Smelly farts are born of sulfur, which is more common in a diet containing garlic, onions, crucifers like broccoli or cabbage, fish, eggs or meat. Plant-Powered Plus We wondered what might be included in the “plus” category when you feed your gut and fight inflammation. Dr. B. offers a few things that you might not expect in a book about diet, but they are related to reducing inflammation. One is to go outside early in the day, every day, to get your circadian rhythm in sync. Another is to maintain your emotional connections with family and friends. Still another, just as important, is to nurture your spiritual core. This Week’s Guest Dr. Will Bulsiewicz describes how a plant-powered diet can fight inflammation Will Bulsiewicz, MD, is a New York Times bestselling author, award-winning gastroenterologist and internationally recognized health expert. Dr. Bulsiewicz directs the Gut & Microbiome Center for Excellence, a physician-led executive medicine and telemedicine practice based in Mount Pleasant, SC. Dr. Bulsiewicz is the author of several books, including his latest book, Plant Powered Plus: Activate the Power of Your Gut to Tame Inflammation and Reclaim Your Health.

Are you buying the same vegetables he does? We also get insights on his favorite recipes for grains like farro. And we discuss the effect of coffee on the gut microbes. If you want to feed your gut to encourage certain microbes, remember that consistency is crucial. You can’t eat a specific food once and expect it to make a difference.

  Show 1192: How a Scary Fungus-Candida auris-Is Threatening the World 13.08.2026 56min

  You may have heard about antibiotic-resistant bacteria. They can greatly complicate the treatment of infections. But have you ever heard of antifungal-resistant fungus? Infectious disease experts knew nothing about a scary fungus, Candida auris, in 2008. But in less than two decades this dangerous fungal infection is making waves around the world. It has acquired resistance to a number of potent antifungal medications. Consequently, it now poses threats of hard-to-treat infections in many corners of the globe. At last count, 27 states in the US have reported cases. We first reported on this serious fungal infection in 2019. At that time it seemed worrisome, but not widespread. Now, thousands of people have been infected over the last eight months. The CDC consider this scary fungus an “urgent threat.” Why is Candida Auris Making Headlines This week? We scan a variety of sources for our People’s Pharmacy “Health Headlines” newsletter. There are an amazing number of scary stories showing up around the country. The headlines from Forbes (June 30, 2026) really caught our eye: “A Drug-Resistant Fungus Is Spreading Through American Hospitals” “Candida auris, a drug-resistant yeast, saw clinical infections more than double from 2022 to 2024, reaching 6,197 cases. This fungus primarily threatens immunocompromised patients, resisting common antifungal treatments.” Researchers at the University of California, San Francisco describe in the journal Science, (August 6, 2026) why it is so hard to get rid of this infection once it has set up house keeping on a patient’s skin. When the fungus gets into and around hair follicles, it creates a kind of nest that protects it from an attack by our immune system. Once it is embedded, Candida auris can be extremely hard to eradicate. That’s true in hospital environments as well in a personal environment, such as a hair follicle. Most healthcare professionals believe that the problem exists primarily within nursing homes. Older people, who are immune compromised, are especially vulnerable. But millions of Americans are immunosuppressed. Many may not even realize they are at risk. What Is Candida Auris? New York Times journalist Matt Richtel was looking for a suitable topic for a series of in-depth reports. When he asked the experts at the Centers for Disease Control and Prevention, they suggested he investigate Candida auris.  They were more worried about this scary fungus than about most other health problems, and when you listen to his story, we think you will be, too! Candida auris was first identified in the ear of a Japanese woman almost two decades ago. It wasn’t making her sick. Nonetheless, before long infectious disease experts started finding people who were very sick with this fungus. Because several strains have developed resistance to multiple common antifungal medications, the infections can be quite difficult to treat. Who Is at High Risk? People whose immune systems are compromised seem to be at highest risk. That includes the elderly, especially those living in nursing homes. However, millions of people taking medications that can suppress their immune systems are also in danger. These are drugs used to treat autoimmune conditions such as rheumatoid arthritis, Crohn’s disease, inflammatory bowel disease or plaque psoriasis. What actions do we need to take to protect them? With the development of antifungal resistance, simple surgical procedures could pose life-threatening risks. This Week’s Guest: Matt Richtel is a reporter at the New York Times. He won the Pulitzer Prize for national reporting with a series of articles he expanded into his first nonfiction book. Ultimately, it became a New York Times bestseller, A Deadly Wandering. Matt Richtel’s latest book is An Elegant Defense: The Extraordinary New Science of the Immune System: A Tale in Four Lives. His website is www.MattRichtel.com/ You can find his series on Candida auris at The New York Times. The photograph of Matt Richtel is by Simona Deac.

I promise you that this is a memorable interview that you do not want to miss. And remember, The People’s Pharmacy was informing you of this threat years before most people had even heard of this scary fungus.

  Show 1482: Are Your Kidneys in Trouble? Two Tests Could Tell You 07.08.2026 1h 6min

  Our kidneys do an incredible job filtering our blood every hour of every day. Most of us have two kidneys, and each one has about a million microscopic filters called glomeruli. Unlike the filters in our HVAC system, though, these filters cannot be replaced. But they do their work so well and unobtrusively that most of us don’t even think about our kidney function. Although 37 million Americans have kidney trouble, the majority are unaware of their situation. Two tests could reveal how well the kidneys are working. What are they, and how often should you ask about them? At The People’s Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment. How You Can Listen You could listen through your local public radio station or get the live stream at 7 am EST on Saturday, August 8, 2026, through your computer or smart phone (wunc.org). Here is a link so you can find which stations carry our broadcast. If you can’t listen to the broadcast, you may wish to hear the podcast later. You can subscribe through your favorite podcast provider, download the mp3 using the link at the bottom of the page, or listen to the stream on this post starting on August 10, 2026. What Are the Two Tests That Reveal Kidney Trouble? Chronic conditions like high blood pressure and diabetes put a strain on the kidneys. They are very common problems that signal the need for kidney function monitoring. Our guest expert, Dr. Samir Parikh, suggests that all of us should know our numbers. One is derived from the level of creatinine in the blood. This is normally part of a basic metabolic panel. Usually, the panel results will include a number for the estimated glomerular filtration rate (EGFR) calculated from the value for blood creatinine. The other crucial test is a urine test for protein. Keeping Kidneys Healthy by Staying Properly Hydrated One of the simplest tactics to keep kidneys healthy is to provide them with enough liquid. We get some fluid from the food we eat, which may be one reason eating fruits and vegetables seems to be good for us. They are full of water! We also need to drink fluid, and plain water is probably the best choice. It would be smart to use thirst as a guideline and make sure to drink when thirsty. We do avoid overdoing water consumption, though, as overloading the kidneys with more fluid than they can handle is dangerous as well. Medicines That Are Hard on the Kidneys We mentioned to Dr. Parikh the experience of an older friend, a devoted runner, who discovered that taking ibuprofen after a run reduced the likelihood of having to get up overnight to urinate. He reminded us and our listeners that nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, naproxen, celecoxib or meloxicam can be hard on the kidneys. That doesn’t mean we shouldn’t ever take such pain relievers, but perhaps we should try not to make it a habit. When we asked about other medicines that might be tough on the kidneys, he mentioned PPIs. Proton pump inhibitors such as omeprazole (Prilosec) or esomeprazole (Nexium) are often used to treat heartburn or other digestive symptoms. Regular use can put a strain on the kidneys, although the gastroenterologist recommending the medicine might not warn you of that side effect. We asked about environmental toxins and learned that heavy metals such as lead or arsenic can harm the kidneys along with other organs. We should make sure that the food we eat and the water we drink are not contaminated with such compounds. The Possible Benefits of Vitamin B Dr. Parikh has been studying how the kidneys respond to the B vitamin nicotinamide. The preliminary work he and his colleagues have done so far is promising. However, they have not conducted clinical trials to find out whether the vitamin could help people with early kidney disease. Because kidneys work so hard, they need a lot of energy to be produced by the mitochondria in their cells. Those mitochondria need NAD+ (nicotinamide adenine dinucleotide) to function at their best. Providing additional nicotinamide appears to help (Nature Reviews. Nephrology, Feb. 2020).  One to three grams a day appears to be safe and may be beneficial. Medications That Can Promote Kidney Health Some medicines initially developed for other conditions are proving to be helpful in treating kidney disease. In particular, these include diabetes drugs known as SGLT2 inhibitors like dapagliflozin (Farxiga) or empagliflozin (Jardiance). They help slow the decline of kidney function (New England Journal of Medicine, Nov. 4, 2022). GLP-1 agonists may also be familiar because they too are used to treat diabetes. Medications such as semaglutide (Ozempic, Rybelsus, Wegovy) and tirzepatide (Mounjaro, Zepbound) have made headlines as weight loss and diabetes meds, but they also can reduce the risk of kidney failure and other bad outcomes (Lancet. Diabetes & Endocrinology, Jan. 2025). The benefits of these types of drugs should give us hope that we can go from slowing the progression of kidney disease to stopping it in its tracks Taking Care of Your Kidneys We asked Dr. Parikh what we should be doing to care for our kidneys and keep them healthy. He urged us once again to know our numbers: most importantly, the numbers from the two tests we discussed, blood creatinine and urine protein. Other numbers that are important for kidney are our blood pressure and, for those with diabetes, HbA1c. In addition to paying attention to all those numbers, we need to embrace a lifestyle that will help keep them where they belong. That means following a heart-healthy diet, staying physically active and getting adequate sleep. This Week’s Guest Samir M. Parikh, M.D., FASN, is Professor of Internal Medicine and Pharmacology and Chair of Internal Medicine at the University of Texas Southwestern. He holds the Donald W. Seldin Distinguished Chair in Internal Medicine and the Ruth W. and Milton P. Levy, Sr., Chair in Molecular Nephrology.

This week’s podcast has additional information on a possible role for sodium bicarbonate (baking soda) for kidney function.

  Show 1481: Flip-Flops, Fungus and Foot Pain: What Are Your Feet Trying to Tell You? 30.07.2026

  Millions of people suffer with foot trouble. Some have heel pain when they first get out of bed. Others complain of flat feet or bunions. Athlete’s foot is very common, though it doesn’t always respond as expected to antifungal medications. Speaking of fungus, toenail fungus can be extremely stubborn. What are your feet trying to tell you about what they need? How can you keep them healthy, especially in the summertime? At The People’s Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

You can subscribe through your favorite podcast provider, download the mp3 using the link at the bottom of the page, or listen to the stream on this post starting on August 3, 2026. What Are Your Feet Trying to Tell You? Most everyone looks forward to summer vacation, but that special time away from the usual routine may pose challenges for your feet. Whether you are hiking in the mountains or running on the beach, you may need to pay attention to your tootsies. Time at the Beach Beach time can inspire long walks on the sand, but soft sand could really put a strain on foot muscles that aren’t accustomed to it. Our expert guest, podiatrist Jane Andersen DPM, recommends wearing good running shoes for walking long distances on sand. Choosing to walk where the sand is hard-packed when the tide is low can also be helpful. Possibly the most important but easily overlooked step to protect feet at the beach is to apply sunscreen. The tops of the feet are easily overlooked, but they can burn pretty readily. And if you are planning to spend time sunbathing prone, you might even want to apply sunscreen to the bottoms of your feet. They never see the sun, and walking on sunburned soles could be quite painful. Protecting Bare Feet Another consideration at the beach is how you will get from the parking lot or boardwalk to the water. How hot is the sand? If it is hot enough to burn the soles of your feet, you might consider using water sandals. In general, going barefoot can be risky. Whether you’re at the beach, at a campground, in your own backyard or even inside your home, there are potential hazards underfoot. Bits of glass shards, little pieces of wire, tiny pebbles or nails could all cause havoc if they end up embedded in a sole. Protecting your soles by wearing good flip-flops makes a lot of sense. To find a list of flip-flops that provide appropriate arch support as well as sole protection, consult apma.org. Treating Black Toenails During this episode, Joe describes a trip to the beach with a long walk. By the time he removed his shoes, his longest toe had a black toenail that was rather painful. Although the pain faded before too long, it took about a year for the dark color to disappear from the nail. Dr. Andersen suggests that it often takes at least nine months to regrow a toenail. She emphasizes that if the nail turns black due to sudden trauma (like dropping something heavy on the toe), a podiatrist should check it out. Sometimes there is a fracture under that discolored nail that requires medical attention for proper healing. What Is the Story on Flat Feet? Joe has always had flat feet. Perhaps your feet are flat, too. The condition is pretty common. If Joe gets out of a bathtub or swimming pool and leaves footprints, they are almost oval. There is very little indentation in the center. Other people with higher arches may leave footprints that are nearly C-shaped. Flat feet can benefit from arch support such as orthotic inserts for shoes. High arches can also cause trouble, especially if they are linked to a genetic condition called Charcot-Marie-Tooth. It is a nerve disorder that can also lead to muscle weakness. Consequently, people with high arches may also need podiatric care for their feet to stay comfortable and healthy. Plantar Fasciitis Is a Pain The bottoms of your feet have thick connective tissue called fascia that run from the heel to the ball of the foot. Inflammation of this tissue causes pain, typically at the heel but sometimes along the arch. Often, more supportive footgear or special orthotics can help. Getting a shoe with the correct heel drop is important. That is the difference between the height of the shoe at the heel and at the toe. A podiatrist can recommend the most appropriate heel drop for your feet. Stretching is also useful, particularly pulling the toes toward the knee or stretching the calf in a runner’s stretch pose and holding for 30 seconds or so. Rolling the bottom of the foot on a frozen water bottle helps with the stretch at the same time that the cold eases the inflammation. Plantar fasciitis is common and treatable. If left untreated, it may last a long time. What Can You Do About Stinky Feet? A couple of listeners shared their experiences with smelly feet, and we asked Dr. Andersen for her opinion. Jan described using a topical erythromycin antibiotic prescription that came as a roll-on. She also got rid of all her stinky shoes and is careful to wear socks that will wick sweat away. Dr. Andersen noted that erythromycin is very effective against a bacterial infection with Corynebacterium minutissimum. This organism glows coral under ultraviolet light and can definitely raise a stink. Sophia wrote about developing smelly feet after walking around in wet shoes. She finally solved the problem by treating her feet with rubbing alcohol. Dr. Andersen agreed that rubbing alcohol could be helpful. So can soaking the feet in a strong solution of tea. Other tips include cleaning the floor of the shower stall frequently and always wearing socks that wick–not cotton, which absorbs sweat but traps the moisture. Acrylic or wool work better. Another tactic is to alternate shoes; don’t wear the same shoes day after day but give them at least a day to dry out. How Should You Treat a Sprained Ankle? There has been controversy lately about the standard RICE protocol for a sprain: rest, ice, compression and elevation. Some experts now recommend warmth instead of ice and gentle motion rather than rest immediately after a sprain. Of course, the first step is to ascertain that it is really a sprain and not a fracture. The treatment for those two injuries is completely different and the person suffering the problem may not be able to tell just from the way it feels. An X-ray is prudent. Bunions and Hammer Toes If you don’t suffer from bunions, you might not know what they are. In a bunion, the bone that supports the big toe (the metatarsal) moves out of alignment and starts to point more towards the midline of the body. To compensate, the rest of the big toe ends up pointing back toward the rest of the foot. This creates a bump on the edge of the foot that might be painful. There doesn’t seem to be any clear correlation between the size of the bump and the amount of pain it causes. Bunions seem to be hereditary, at least to some extent. Conservative management entails choosing footwear with a roomy toe box, not pointy-toed shoes. Podiatrists also correct bunions surgically. They can choose from a wide range of surgical approaches. In hammer toes, one of the toes (typically the second toe) curls over so that the end that would normally face forward points downward. This too can be corrected surgically, but the recovery can be pretty lengthy. A roomy toe box is also a good bet for living with hammer toe. Taking Care of Your Feet We asked Dr. Andersen for general advice, and she suggested that one very important consideration is to buy your athletic shoes in person, preferably at a store that caters to athletes. Buy the proper shoes for your activity; in other words, don’t try to play pickleball in running shoes. One nationwide chain that does a good job fitting the shoe to the athlete is Fleet Feet. Locally, she recommends Bull City Running. This Week’s Guest Dr. Jane Andersen, Board Certified, American Board of Foot and Ankle Surgery, is in practice at Chapel Hill Foot and Ankle, part of FASMA, Foot and Ankle specialists of the Mid Atlantic, in Chapel Hill, North Carolina.

  Show 1459: Food Is Medicine: Should Your Doctor Be Prescribing Produce? from the archives 30.07.2026

  One of the most basic pillars of health is good nutrition. A range of eating patterns might all be considered balanced diets, but in general people do better when they eat less processed foods and more whole foods. Vegetables and fruits play a starring role in at least two diets that have been studied extensively, the DASH diet and the Mediterranean diet. Americans might be healthier if we followed these eating plans, but fresh veggies can be pricey. If your doctor were prescribing produce, would your insurance plan cover it? Might this make healthful eating more of a practical possibility? At The People’s Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems.

Food Is Medicine Increasingly, healthcare providers are recognizing the critical role of diet in the development of chronic disease. An entire movement is organizing around the concept of Food Is Medicine, both for prevention and for treatment of conditions like diabetes, obesity and heart failure. Scientists have shown that diet makes a difference. Studies have confirmed what many of our grandparents or great-grandparents intuited. On the other hand, translating that knowledge into action that benefits patients has been difficult. One important barrier is the cost of groceries. Our interview with Peter Skillern and Dr. Seth Berkowitz focused on access to fresh fruits and vegetables for lower-income people in North Carolina. Since we spoke with them, we read about an intriguing effort to provide culturally and medically appropriate food for heart failure patients in Navajo Nation. Traditional Foods for Better Heart Health Food insecurity goes hand in hand with medical complications, as the authors of a new study note (JAMA Internal Medicine, July 27, 2026). The results demonstrate that making sure people with heart failure have the food they need can cut hospitalizations. The Diné (Navajo) community helped design the intervention, named Medically Utilized Tailored Traditional Foods to Optimize Nutrition in Heart Failure (MUTTON-HF, probably a reference to a favored food among the sheep-raising Navajo). According to the investigators, “We partnered with local Navajo farmers and ranchers to source meat and produce and with Tocabe, a Native-run kitchen, to produce the medically tailored frozen meals, practicing whole animal utilization and Native first supply chain when possible.” The study provided intensive support, including refrigerators and microwaves to families that did not have them. The researchers  recruited 206 heart failure patients at two Indian Health Service sites in Navajo Nation to participate. A total of 206 patients were randomly assigned to receive culturally and medically tailored meals along with their healthcare or to get usual care without meals. The meals were designed to follow DASH (Dietary Approach to Stop Hypertension) sodium-restricted guidelines. For example, one breakfast provided consisted of blue corn meal, blueberries, bison sausage, potatoes and butternut squash. A sample lunch included mutton, steamed corn, blue corn meal and wild rice. People in the control group, who got no meals during the trial, could opt for an equivalent number of meals to be provided after the study assessment was completed. This was deemed fair by the community. By the end of the two month trial, 40% of those getting meals had needed emergency care or hospitalization. In comparison, 57% of those who did not receive meals needed hospitalization or emergency intervention. The rate of hospitalization for heart failure was sharply different, 4% vs. 13%. The authors conclude: “Community-based interventions that leverage protective assets of Native communities are needed to advance Indigenous health.” What Should We Learn from the MUTTON-HF Trial? An editorial (JAMA Internal Medicine, July 27, 2026) pointed to some of the unusual features of the experiment that contributed to its success:  “Success required collaboration between local Diné (Navajo) community-based organizations, kitchens and food producers, working alongside Indian Health Services, clinicians, and academic partners. “Importantly, the study team prioritized listening to community and prepared meals using foods foundational to Diné cuisine.” The editorialists note that this food is medicine approach has the potential to be even more powerful than some potent medications: “The second takeaway is that healthy, Indigenous foods and a community-centered approach resulted in larger reduction in HF-specific hospitalizations than a recent trial of glucagon-like peptide-1 (GLP-1) receptor agonists,2 a medication now driving a $100 billion industry. A medication with trial evidence showing the same results as this meal study, particularly one with such a favorable adverse effect profile, would be a major therapeutic achievement and likely covered by insurance. This framing is not to pit medically tailored meals and GLP-1 drugs against each other, but rather to highlight the scale of improvements observed in this study. Meals and other treatments such as GLP-1 drugs are not mutually exclusive and can have complementary benefits, as GLP-1 drugs do not necessarily improve dietary intake. One treatment represents a marvel of pharmaceutical innovation; the other reflects the power of healthy meals rooted in cultural celebration.” Doctors Prescribing Produce In North Carolina, the approach was different. In former times, people could get healthful food in a variety of ways. Past generations often had gardens and grew much of their own produce. That’s not always practical in urban settings or for families with multiple jobs struggling to make ends meet. Our guests today have tested two ways to get fresh food into people’s hands. One is a debit card that can be used to buy any WIC-approved food at more than 66,000 retail outlets across the country. WIC is the USDA supplemental nutrition program for Women, Infants and Children. WIC-approved foods include fresh fruits and vegetables with no added sugar or salt. In this model, the healthcare provider arranges for certain patients to get access to this debit card, providing $40 worth of purchasing power for healthy foods each month. They are essentially prescribing produce. The idea is to use a business model that supports good food and saves the health system money. This is termed a healthy food subsidy. The other approach is a food box. This includes vegetables and fruits, and possibly other foods, that providers decide the patients should get. In some initiatives, the person or agency deciding what goes in the food box might also take into account what is available from local farmers. The box may be distributed weekly, every two weeks or every month, but the individual who is going to be eating the food does not choose what is in it. How Does a Healthy Food Subsidy Compare to Food Boxes When Providers Are Prescribing Produce? When people don’t know if they will be able to pay for the groceries they need, they are said to be “food insecure.” This complicates a range of chronic conditions, making diabetes more challenging, for example. People with food insecurity have a harder time keeping their blood pressure under control. Our guests collaborated with other colleagues on a recent comparing the food box approach to the healthy food subsidy among North Carolina resident with high blood pressure and food insecurity (JAMA Internal Medicine, Dec. 1, 2025). The study enrolled 458 individuals. Everyone in the study had a provider prescribing produce. Half the volunteers got the food subsidy debit card and half were provided with food boxes. Those getting the food subsidy had moderately lower blood pressure after six months compared to those getting food boxes. Their blood pressure was also lower after a year and a half. Food insecurity decreased in both groups over time. Tackling Food Insecurity One of the outcomes of food insecurity is that people are more likely to need emergency department services. This costs the insurance company dearly. If improving food security and diet quality could reduce ED visits, insurers might become quite interested in the food subsidy approach. This is currently being tested for participants with heart failure. Special Populations Who Might Need Providers Prescribing Produce During this conversation, we expressed concern about vulnerable populations that might suffer especially from cuts in government spending. We asked about school lunches and we learned about pilot programs focusing on expectant mothers. Children in foster care are especially vulnerable; a food subsidy program taking a Food Is Medicine approach could be helpful for them. This Week’s Guests Seth A.

Welcome to this podcast of the People’s Pharmacy. Joe 00:06-00:27 You can find previous podcasts and more information on a range of health topics at peoplespharmacy. com. Good nutrition is an undisputed pillar of health. Sadly, it seems to be out of reach for too many Americans. This is the People’s Pharmacy with Terry and Joe Graedon. Terry 00:34-00:40 What if modern medicine made nutrition a priority? How would that change what we eat? Joe 00:40-00:54 The food industry has learned how to make ultra-processed food tasty and accessible, even in food deserts. But is it contributing to our epidemic of obesity, diabetes, and heart disease? Terry 00:55-01:00 How is the Food is Medicine movement changing our approach to fresh fruits and vegetables? Joe 01:01-01:06 Coming up on The People’s Pharmacy, should your doctor be prescribing produce? Terry 01:14-02:11 In The People’s Pharmacy Health Headlines: The CDC is reporting that the flu season might have peaked. Laboratory testing suggests a downward trend in flu cases. That said, this federal agency is estimating that 18 million people have caught the flu so far and 230,000 patients have been hospitalized. We’re also nearing an approximate 10,000 deaths from the flu. The CDC has classified children as experiencing high severity influenza this season and adults moderate severity. Some experts are challenging the CDC’s numbers. That’s because the data are delayed by about two to three weeks. We may still be in the early stages of this influenza outbreak. Australia’s flu season, for example, started early and lasted a long time. In the U.S., February is often our peak month for flu. Joe 02:11-02:55 A report in JAMA Internal Medicine suggests that older people who get high-dose influenza vaccines are better protected against infection. Over 300,000 Danish citizens participated in a study that randomized to either high-dose or standard-dose flu shots. The investigation covered three flu seasons. This analysis considered how well the vaccination protected against heart failure and other cardiovascular complications, as well as influenza. Those who got the bigger dose had fewer hospitalizations for cardiorespiratory problems. People with diabetes also fared better on the high-dose vaccine. Terry 02:56-03:53 Measles continues to spread at an alarming rate. Earlier this year, there was a large, long-lasting outbreak that started in Texas. While that one has calmed, South Carolina is now in the midst of a serious outbreak. Cases have doubled over the past week or so, and the total number is above 560. While most cases have been seen among children, at least two university populations are also experiencing cases. Both Clemson University and Anderson University are dealing with confirmed measles cases in the student body. There are also cases being reported in North Carolina that seem to be linked to the South Carolina outbreak. Public health authorities point to vaccination rates below 90%, which is not enough to provide herd immunity for people unvaccinated against this extremely contagious and potentially dangerous disease. Joe 03:54-04:20 Last fall, the administration warned pregnant women to avoid acetaminophen because of concerns about autism. A new systematic review in the British journal The Lancet included 43 studies. The authors concluded that there’s no evidence that taking acetaminophen during pregnancy significantly increases the risk for autism spectrum disorder, ADHD, or intellectual disability. Terry 04:21-06:17 Falls are dangerous for older people and can result in injury, limited mobility, and even death. For decades, scientists have wondered whether vitamin D might help with muscle strength and balance and thus prevent falls. The results of studies have been inconsistent. Finnish researchers took advantage of an existing study called the Finnish Vitamin D trial to investigate this question. Nearly 2,500 healthy older participants were assigned to take vitamin D3 at 1,600 international units or 3,200 international units a day or placebo. The investigators collected data on falls and injuries at baseline and at 1, 2, 3, and 5 years. Blood levels of 25-hydroxyvitamin D increased among the individuals taking vitamin D supplements. Over 5 years, just over half of the volunteers had taken a fall and 11% had sustained injuries. Those proportions did not vary much between any of the groups, including those on placebo. The scientists concluded five-year vitamin D supplementation of 1,600 international units a day or 3,200 international units a day did not affect the overall risk of falls or fall injuries among generally healthy, largely vitamin D-sufficient men and women. And that’s the health news from The People’s Pharmacy this week. Welcome to The People’s Pharmacy. I’m Terry Graedon. Joe 06:17-06:43 And I’m Joe Graedon. Our topic today is food. And I have to admit that I’m biased. My earliest years were spent on a dairy farm in eastern Pennsylvania. Even after we moved, visiting Uncle Leo was a highlight because of the vegetables and super fresh whole milk. Uncle Leo and my mom, Helen Graedon, lived into their 90s and prized real food. Terry 06:43-06:55 Good fresh food is a delight that’s not available to everyone. Should we also be thinking of food as medicine? If so, how could we make it affordable and accessible? Joe 06:56-07:02 We have two distinguished guests today who are at the forefront of the food as medicine movement. Terry 07:03-07:37 Dr. Seth Berkowitz is Associate Professor of Medicine at the University of North Carolina School of Medicine and Section Chief for Research, General Medicine, and Clinical Epidemiology. He’s a general internist and primary care doctor studying how food and nutrition interventions can improve health. Dr. Berkowitz is the Deputy Scientific Director of the American Heart Association’s Food is Medicine Initiative. His book is “Equal Care: Health Equity, Social Democracy, and the Egalitarian State.” Joe 07:38-08:03 We’re also talking with Peter Skillern, CEO of the nonprofit agency Reinvestment Partners, an innovative nonprofit that works with people, places, and policy to foster healthy and just communities. In recognition of his leadership, Peter was selected as a William Friday Fellow for Human Relations and as an Eisenhower Fellow for International Relations. Terry 08:04-08:06 Welcome to The People’s Pharmacy, Peter Skillern. Peter Skillern 08:07-08:08 Thank you so much, Terry. It’s good to be here. Terry 08:09-08:12 Welcome to the People’s Pharmacy, Dr. Seth Berkowitz. Dr. Seth Berkowitz 08:12-08:13 Thank you. I appreciate the invitation. Joe 08:14-08:25 We are delighted to be able to talk about one of our favorite topics, which is food. And, you know, Terry’s grandparents were very involved with food a very long time ago. Terry 08:26-08:41 That’s true. My grandfather was the butcher in the little town in western Nebraska where they lived. And my grandmother had a huge garden and raised chickens. I mean, it wasn’t a hobby. It was just, you know, what you did. Joe 08:41-09:09 And my grandfather, at the early part of the 20th century, was a back-to-the-land kind of guy. He bought a farm in Pennsylvania, and my uncle Leo ran that farm for decades. He was a dairy farmer. And my mom and dad were always very big on gardening. They had a huge garden, and they prized their fresh vegetables. Like you would eat them in the garden because they were so delicious. Terry 09:10-09:43 Well, you know, most people today don’t have that experience. They don’t have the space. They don’t have the time to do a garden. They may not have the knowledge. So how can people get the food? What they do is they rely on supermarkets, but produce is expensive. So when budgets get tight, often what people do is they cut back on the fresh fruits and fresh vegetables and they look for food that’s cheaper, which often is more processed. Joe 09:44-10:05 And not very good for you. So let’s go back a couple thousand years to Hippocrates, who is reported to have said, let food be thy medicine, let medicine be thy food. So let’s start at the very beginning. Peter Skillern, what is the Food is Medicine movement? Peter Skillern 10:05-10:21 It’s an initiative that’s nationwide of practitioners, health care providers, insurance companies, and I think most importantly patients who are asking that the health care system assist them with their health by helping them pay for food. Joe 10:22-10:24 How did you get interested? Peter 10:24-10:49 Well, I run an anti-poverty organization, and we’re committed to helping improve people’s lives, their health, and their food security. But an important component of that is to find a business model that sustains it. We have to move beyond simply grant-based or charity. We need to find a business model where the health care system says it’s in our financial interest and in our obligations for good health care to help provide food. Terry 10:49-10:51 Tell us a little bit more about that business model. Peter Skillern 10:53-11:18 Well, ideally, we’re trying to show that we can save the health care industry money. About 80% of health care costs are created by this treatment of chronic diseases related to unhealthy food, diabetes, cardiovascular, liver disease. So if we can help show an improvement in those conditions, reducing costs, we hope that the health care system will pay for food like it pays for medicine. Terry 11:18-11:24 So going to another old aphorism, an ounce of prevention being worth a pound of cure. Peter Skillern 11:25-11:27 It’s both prevention and it’s treatment. Joe 11:27-11:56 Well, let’s turn to Dr. Berkowitz. Dr. Berkowitz, you have a medical degree and a PhD. You’re an internist. You see people with cardiovascular disease and diabetes and all sorts of other conditions. Are there any studies, any science to support what we’ll call the food is medicine movement that fruits and vegetables actually make a difference in people’s outcome? Dr. Seth Berkowitz 11:56-12:41 Yeah, I think there are a lot of studies, actually. So one of the things that we think about for food as medicine is how can we use various ways of providing healthy food resources to overcome barriers people might have to healthy eating. And as we were alluding to, there are a lot of different conditions where that might be relevant. And so there’s been a real burgeoning of studies across a number of different clinical populations that try to use food as medicine principles to improve health outcomes. That could be improving things like blood pressure or blood sugar. That could be improving things like a reduced need for emergency department visits or hospitalizations and really a number of different clinical outcomes that might be affected by food is medicine study or food is medicine intervention. Joe 12:41-12:59 It sounds like medicine is, I’ll say, rediscovering what our great, great grandparents knew, you know, almost intuitively from the time they were young kids until the time they died. It was like, yeah, food, food is essential for good health. Dr. Seth Berkowitz 12:59-13:59 Yeah. I mean, I think there’s no doubt that nutrition is, you know, a key part of health. An analogy that I sometimes like to use for food as medicine is with physical activity and exercise. So we know that physical activity and exercise are also key parts of health. They go on throughout our lives and are not necessarily connected to health care or the health system, even though they help make us healthy. But there are certain circumstances, say after an injury where you might get physical therapy or after a heart attack where you might have cardiac rehab, that physical activity and the health care system intersect to promote health. And I see food as medicine analogously. Food means lots of different things, lots of different people. It’s culture, it’s celebration, it’s nutrition. And some of that might not be in any conjunction at all with the healthcare system, and that’s totally fine. But there are certain situations, maybe with high blood pressure or with diabetes or other things, where the intersection of food and the healthcare system might produce a health benefit in a way that’s analogous to how physical therapy can produce health benefits. Terry 13:59-14:20 You’ve mentioned high blood pressure a couple times, and Joe asked about research. And we know that there is a diet that can help people lower their blood pressure. It’s called the DASH diet. Tell us a little bit more about that and the pretty robust research backing that it has. Dr. Seth Berkowitz 14:20-15:10 Yeah, so the DASH diet, I think, is one of the best studied dietary interventions. It focuses on things like having lower sodium content in the diet, higher potassium content, which generally comes from eating fruits and vegetables, using healthy fats, not having a lot of refined grains or carbohydrates, and things like that. It’s been shown to lower blood pressure in a number of randomized trials. It’s an overall healthy dietary pattern and likely has impacts on other types of cardiometabolic disease, things like heart attacks or strokes or things like that, even though it was originally designed for high blood pressure. And if there are ways to help people follow a DASH diet, then that’s likely to have very big health impacts. Also just to say, I think that’s one example of a healthy dietary pattern, but there are lots of diets that is not something that is preferred or culturally appropriate or things like that. Joe 15:11-15:43 Peter, we have all been told by every healthcare professional that we’ve ever interviewed, don’t smoke, exercise, and eat a well-balanced diet. It’s sort of like a mantra. And yet it doesn’t mean much to people. It’s sort of like, ‘Oh, yeah, okay, I’ve heard that a dozen times, a hundred times. How do I implement that in my life? How do I make that part of my real-world experience?’ Terry 15:44-15:48 Can I balance my diet with potato chips in one hand and chocolate cake in the other? Joe 15:49-16:00 So how do you make it possible for people who are on the edge sometimes in terms of their finances to be able to get really healthy food? Peter Skillern 16:02-16:20 The biggest obstacle to eating healthy for low-income people is the cost of the food. And our program in providing a $40 benefit or $80 on a card that’s restricted for healthy fruits and vegetables at almost any retailer allows them to choose and buy that healthy food. Joe 16:20-16:22 How does it work? Tell us about that card thing. Peter Skillern 16:23-16:45 Yeah, so we do a debit-restricted card that can purchase any WIC-approved fruits and vegetables at almost any retailer in the country. So it empowers people both the purchasing power, but also the choice of where they purchase it, what they purchase, when they purchase it. And that high agency that’s been given those participants leads to higher compliance with eating healthy. Terry 16:45-16:52 Now, Peter, you said WIC approved. WIC, I think that stands for women, infants, and children. What does it mean? Peter Skillern 16:53-17:03 It means that you can do produce that does not have any additives to it. So it could be canned or frozen as long as there are no salts or sugars added. Joe 17:03-17:11 So let me see if I understand this. You get a card, a debit card, and you can go anywhere? Peter Skillern 17:12-17:31 We have this particular card. It is recognized at 66,000 retail outlets across the country. So most food as medicine efforts are very locally based, perhaps food boxes from locally grown food. And what we’re trying to do is to reach the scale and impact that the health care system needs. Joe 17:31-17:32 Do people like it? Peter Skillern 17:33-17:40 They love it. We have a 95% net promoter score, which means that they would refer it to their family and friends. Terry 17:42-18:11 You’re listening to Peter Skillern, CEO of Reinvestment Partners, a nonprofit based in Durham, North Carolina, working to foster healthy, just communities. The agency is a state and national leader in its field. We’re also talking with Dr. Seth Berkowitz, Associate Professor of Medicine at the University of North Carolina at Chapel Hill. He is the author of the recent book, Equal Care, Health Equity, Social Democracy, and the Egalitarian State. Joe 18:12-18:17 After the break, we’ll find out if getting rid of the cost barrier can make people healthier. Terry 18:18-18:23 Doctors are accustomed to prescribing medications; they might not be used to prescribing produce. Joe 18:24-18:32 When you compare produce debit cards to a food box, what are the differences? And what is food insecurity and how does it affect health? Terry 18:39-18:47 You’re listening to The People’s Pharmacy with Joe and Terry Graedon. Terry 20:37-20:40 Welcome back to The People’s Pharmacy. I’m Terry Graedon. Joe 20:40-20:49 And I’m Joe Graedon. The topic today is food is medicine. That’s a message we’ve been preaching for decades here on The People’s Pharmacy. Terry 20:50-20:58 Americans spend more on health care than any other nation, but we lag far behind most other developed countries when it comes to longevity. Joe 20:59-21:14 Many health professionals praise the Mediterranean diet because of its fresh produce and emphasis on real food. But many Americans find it difficult to afford fruits and vegetables. How can we change that? Terry 21:14-21:36 Peter Skillern is CEO of the nonprofit agency Reinvestment Partners, an innovative nonprofit that works with people, places, and policy to foster healthy and just communities. In recognition of his leadership, Peter was selected as a William Friday Fellow for Human Relations and as an Eisenhower Fellow for International Relations. Joe 21:37-22:00 We’re also talking with Dr. Seth Berkowitz, Associate Professor of Medicine at the University of North Carolina at Chapel Hill. Dr. Berkowitz is the Deputy Scientific Director of the American Heart Association’s Health Care by Food Initiative. His recent book is Equal Care, Health Equity, Social Democracy, and the Egalitarian State. Terry 22:02-22:56 Dr. Berkowitz, I am assuming, and I should never do that, that in order for people to embrace this idea of food is medicine, you have to be able to prove it. If we want people to start eating more fruits and vegetables, we have some evidence already that eating more fruits and vegetables is good for you. We talked about the research on the DASH diet. There’s research on the Mediterranean diet. Both of those diets are very heavy on produce. So what we’ve got are barriers. And Peter has mentioned that the big barrier is cost. How do we prove that getting rid of that cost barrier can actually make people healthier? Dr. Seth Berkowitz 22:57-24:44 I think that’s a great question, and I think that’s a great way to frame it as well. I don’t think we need any more research that a healthy diet is healthy. I think we generally know what healthy foods are and what it will do for us. But the question is, how do we overcome those barriers to following a healthy diet that so many people face? Some of those barriers are knowledge-based, and so things like educational programs and things like that make sense. But as you point out, affordability is a key barrier for a lot of people in the United States. And I think that’s the key innovation of Food is Medicine programs, is there’s not only the sort of knowledge and skill building that educational programs have been providing for a while, but there’s the provision of healthy food resources that make it easier for people to overcome that affordability barrier. But also, as you say, overcoming the affordability barrier means that there’s going to be an input of financial resources into the health care system or through the health care system to an organization like Peter’s to run programs and those kinds of things. And so people are going to be looking for strong evidence that doing that really will improve people’s health. And that’s a lot of the work that I do. So I’m a physician by training. I’m a practicing primary care doctor. But I also do research. Some of that is observational research, but a lot of it is interventional research, randomized clinical trials, evaluations of interventions that are being done across our state in North Carolina and really across the country now, and looking for that evidence that shows, all right, this is the right interventional approach in the right population for the right duration of time to make it a truly covered benefit in the same way we might say that, oh, if you have a certain type of infection, you don’t just need antibiotics broadly. You need some type of antibiotics in a certain dose for a certain period of time. And that’s what turns it into a real medical intervention that can be covered through insurance benefits or things like that. And similarly, there’s a body of research that’s being built around food as medicine interventions to do that same kind of thing. Joe 24:45-25:50 Well, Terry said that everybody knows that food as medicine is good for you and making the right choices. But I would actually take an exception to that because I think our grandmothers great-grandmothers knew that. I’m not sure that everybody recognizes how powerful food is, especially, and I hate to say this, Dr. Berkowitz, your colleagues, because a physician is trained, let’s be honest, to write a prescription. They’re trained to look for double-blind, randomized, placebo-controlled trials in the New England Journal of Medicine or fill in the blank journal. And so the idea of spending any time at all with a patient talking about food choices seems like a waste of time. You know, I’m busy. I’ve got 10 minutes to see this person. Let me just write a prescription for, I know, atorvastatin. That’s the answer, because it’s got science behind it. Terry 25:50-25:55 And possibly the physician is assuming that the patient knows how to eat. Joe 25:56-26:13 There are a lot of assumptions that are made. So, you know, how do you, as a health care provider, help your colleagues begin to embrace the idea that, you know, you could perhaps help people lower their blood pressure with a food-as-medicine approach? Dr. Seth Berkowitz 26:14-27:39 I think that’s a very fair question. I think your description of the constraints that people are facing in practicing medicine is very accurate. I think there are these time constraints. I think there is a historic focus on pharmaceutical treatments and, you know, surgical interventions and those kinds of things, but for what physicians are doing. But I don’t think that means that the healthcare system overall is not able to do this. For example, you know, we have professionals who have a lot of expertise in doing exactly what you’re saying, registered dietitian nutritionists. And I think we could be doing a lot more to bring those folks into the care team even more than they already are. Expand the number of situations in which they’re being used. But I do think physicians need to recognize the importance of diet for both preventing and managing chronic disease. And I think there are gains being made in that area, but it’s not exactly where we want it to be. I also think we need to recognize the complementarity between a lot of these different interventional approaches. I think we’re fortunate to have the amazing science that we have that has brought medications that can lower cholesterol or lower blood pressure or lower blood sugar. But we also are fortunate to have the science that is proving that there are ways to use diet to do similar things. And it’s not an either-or situation. You’re probably even better off, at least in the appropriate circumstances, using both approaches to get as much benefit as possible. Terry 27:40-27:54 Well, let me ask. You all have recently collaborated on a couple of publications showing your research. Would you tell us about that, please? Dr. Seth Berkowitz 27:58-28:38 Sure. I’m happy to start and let Peter join in. So there have been two recent, you know, sort of studies that I think are worth talking about. One is a randomized trial where we compared two different types of food as medicine approaches. One approach used a food subsidy provided by reinvestment partners and compared it to the delivery of a food box and looked at whether one was better than the other in terms of lowering blood pressure. And we found that people in both groups had their blood pressure go down from baseline. But the food subsidy had blood pressure, the people in the food subsidy group, I should say, had blood pressures that went down even more than in the food box group. Joe 28:39-28:45 Let me ask you to pause there. Peter, tell us the difference between these two groups because a food box, I don’t understand. Peter Skillern 28:46-29:04 A food box is typically put together with the provider determining what goes in the box, produce or meats, proteins, dairy or not. Maybe it’s just the produce. And it’s typically whatever is in season at the time in that region. And then they deliver that to the client. Terry 29:04-29:08 So it’s a little bit like your CSA box. Joe 29:08-29:09 Which stands for? Terry 29:10-29:41 Community Supported Agriculture. And that is a program in which you pay the local farmer up front. You pay him $100, $200, and every week for the next four or five weeks during the season, you get a box of whatever it is he or she has grown. But what you’re saying is for this food box, it isn’t whatever the farmer has available, which is how the CSA usually works. It’s whatever the doctor says you need to have, huh? Peter Skillern 29:41-29:42 No, actually, I’m not saying that. Terry 29:43-29:43 Okay. Peter Skillern 29:43-30:16 Ideally, you would have kind of a detailed nutritional prescription for which vegetable, for what diagnosis, for what dosage, for what duration, for what demographic, and it’s very specific. A food box is typically an anti-poverty, anti-hunger program where it’s also trying to support local farmers and local food system. Even if all the food is bought from a retailer, someone else other than the participant is making the decisions. So the recipient receives collards or cauliflower or lettuce or whatever vegetable they may or may not choose. Terry 30:16-30:25 I was going to say, I can already see that there could be some problems with that, because if you get collards and you don’t like collards, it doesn’t help. Peter Skillern 30:26-30:34 And so the card, the food subsidies, allows and empowers the participants to choose which produce they want them to buy. Joe 30:34-30:45 Okay, so we’ve got the food box and we’ve got the card that allows me to make the decision what I’m going to buy. It’s a debit card, basically. What’s the result of the study again? Dr. Seth Berkowitz 30:45-31:06 Yeah, so again, we found that blood pressure went down in both groups. So both interventions, or at least people who received both interventions, had lower blood pressure by the end of the study. But it went down even more amongst people who had the card, the food subsidy, suggesting that maybe that element of choice and being able to match your preferences for what you’re getting could be providing some extra benefit. Joe 31:06-31:10 And how did you feel about the results of the study, Peter? Peter Skillern 31:10-32:33 You know, I never felt like the comparison between food boxes and the card were the essential element. The essential element was, are we reducing hunger? Are we improving blood pressure? Are we able to do that at an affordable rate that makes sense for the healthcare sector? And I think that’s what was so powerful about this study was that our initiative reduced blood pressure of 5.4 over 6.8, which is very significant. It reduced hunger. Both interventions reduced hunger by 40%. And, you know, we were able to do that for about $40 a month. The benefits lasted beyond the intervention. And so while we provided the food for six months or 12 months, it would last 18 months. You know, the comparison I would offer is what is our traditional medical interventions, such as blood pressure, how could this complement those pharmaceutical interventions? How can we help change behavior with this so that people aren’t needing blood pressure medicines? So those are some of kind of the bigger opportunities and questions. To the extent that we’re helping address people’s food needs, let’s give them either source of food, boxes or cards that’s available that there’s support for. But if we’re looking to have it prescribed as an intervention, then we need to look at it for it to work across all requirements. Joe 32:33-32:37 And it sounds like you’ve made a really good first step. Peter Skillern 32:38-32:47 I think very significant first step. Dr. Berkowitz’s research which is unparalleled, and having it published in JAMA is kind of building the body of evidence. Joe 32:48-32:50 And what do your colleagues say, Dr. Berkowitz? Dr. Seth Berkowitz 32:50-33:31 I think people are excited about these findings. I mean, one of the reasons I got into this line of work or this line of research as a primary care doctor is seeing the problems that unhealthy diets cause, seeing the problems that lack of affordability of healthy foods cause, people who want to make changes to improve their health but are just unable to, but feeling like I didn’t have a lot of clinical tools to offer. And a lot of my colleagues feel the same. So now, you know, as we’re seeing, well, hey, maybe there are some interventional programs that can make a difference, that can address these issues, that can address both hunger and food insecurity, along with improving the clinical outcomes and reducing the numbers and those kinds of things. And I think people are very excited about that. Terry 33:32-33:35 Let me ask you, what do you mean by food insecurity? Dr. Seth Berkowitz 33:36-34:09 It’s a great question. So food insecurity is uncertain access to the food needed for an active, healthy life. It’s considered a leading public health indicator. So up until recently, at least, it’s been tracked in the United States every year annually for the last 25-ish years or so. And it’s a way to look at what percentage of people in the population in the U.S. have a secure, a stable source of food and aren’t worrying about where their next meal is coming from or whether they’re going to be able to put food on the table at the end of the month. Terry 34:09-34:11 What are the outcomes associated with food insecurity? Dr. Seth Berkowitz 34:12-34:56 Food insecurity is associated with a large number of negative outcomes very consistently across a very large body of research. So it’s associated with greater prevalence of diet-related diseases like more diabetes, more high blood pressure, more heart attacks. It’s associated with more complications of those conditions once you have them. So not only might it lead to diabetes, but it might lead to diabetes that’s out of control and results in, say, an amputation or needing to go on dialysis. It’s associated with worse mental health because it’s a very aversive condition. So stress, depressive symptoms, anxiety. It’s associated with worse learning outcomes in children. So you can think of lifelong impacts there. Essentially, almost any condition you can think of adding food insecurity into the mix just makes things worse. Peter Skillern 34:57-35:30 One of the key indicators is the usage of the emergency room services, which is expensive for both the hospital and the insurers. We did a study with Atrium Health, which showed that with our intervention, the odds of high utilizers, visitations of three times more in six months, was reduced by 36 percent. You know, that’s a better health care outcome. That’s a better financial outcome. And it’s a better quality of life for the health of those individuals who aren’t spending their time in the ER. And almost all of that is directly related to food insecurity. Wow. Joe 35:30-36:08 Well, emergency department usage is unbelievably expensive. I mean, if you had to pay out of pocket for a visit to the emergency room, it would be very challenging. And it’s not good care in the sense that if you could prevent that emergency room visit, you’d be way ahead. So you’re actually suggesting, am I hearing this right, that food security and good choices can reduce emergency department visits? Is that even possible? Peter Skillern 36:08-36:31 That’s what our study found, but other studies as well. I think most importantly was a study that Dr. Berkowitz did on the Section 1115 Medicaid waiver, Healthy Opportunity Pilots, where food was provided to Medicaid members. And he evaluated the health outcomes and savings and found that there was significant savings primarily in the ER usage. How do your colleagues feel about that? Joe 36:31-36:36 I mean, that’s, you know, reducing the number of visits to the emergency room. That’s huge. Dr. Seth Berkowitz 36:37-37:21 Yeah, I think it’s a really important indicator of people being in better health when issues like food insecurity are addressed. There’s very strong evidence that food insecurity is associated with more acute health care utilization, emergency department visits, hospitalizations, higher health care spending. On average, someone who has food insecurity, their health care spending will be something on the order of $1,500 per year, more than a similar person who was food secure. And we now have interventional evidence that programs that address food insecurity and other health-related social needs like housing and transportation barriers can have exactly these impacts that Peter is talking about. Fewer emergency department visits, fewer inpatient hospitalizations, lower spending on health care services. Joe 37:21-37:29 You would think that health insurers would be totally on board with this project because they’re trying to cut costs. Peter Skillern 37:30-38:26 Well, the particulars matter. You know, for which population do we need to provide this service to? What other related services need to go with it? What diagnosis are we trying to treat? So as an example, we’ll be running a randomized clinical trial with Duke Health to look at those who have cardiovascular failure and have recently been admitted to the hospital. That’s a very specific population. They have a very high cost associated with their treatment, and we believe will be very sensitive and responsive to a healthier diet. So those are the types of questions. I think we have to, more broadly, food is medicine, more specifically, for whom? Underneath what conditions? With what additional services? Gets us to the health care outcomes that help us to save money in our system. We can’t really afford to continue our current trajectory on health care costs. And this is a new, innovative approach to help us solve a bigger problem. Terry 38:29-38:57 You’re listening to Peter Skillern, CEO of Reinvestment Partners, a nonprofit based in Durham, North Carolina, working to foster healthy, just communities. The agency is a state and national leader in its field. We’re also talking with Dr. Seth Berkowitz, Associate Professor of Medicine at the University of North Carolina at Chapel Hill. Dr. Berkowitz is the Deputy Scientific Director of the American Heart Association’s Food is Medicine Initiative. Joe 38:58-39:07 After the break, we’ll talk about some of the highly processed foods that also seem highly addictive. How does the idea of food as medicine combat that? Terry 39:08-39:13 When we look at cutting government spending on food programs, we wonder how that affects children in particular. Joe 39:13-39:15 Will it affect school lunches? Terry 39:24-39:43 you’re listening to The People’s Pharmacy with Joe and Terry Graedon. Welcome back to The People’s Pharmacy. I’m Terry Graedon. and I’m Joe Graedon there used to be a Joe 39:43-39:49 potato chip commercial that challenged viewers with the slogan, betcha can’t eat just one. Terry 39:49-39:55 Nobody says that about apples or carrots, but chips can be addictive. Joe 39:56-40:10 Ultra-processed foods are designed to be tasty and affordable, but not particularly nutritious. What is the Food is Medicine movement doing to counteract the appeal of junk food? Terry 40:10-40:42 We have two guests today who have worked together on some important projects. One is Dr. Seth Berkowitz, Associate Professor of Medicine at the University of North Carolina at Chapel Hill. Dr. Berkowitz is the Deputy Scientific Director of the American Heart Association’s Healthcare by Food Initiative. Our other guest is Peter Skillern, CEO of the nonprofit agency Reinvestment Partners, an innovative nonprofit that works to foster healthy and just communities. Joe 40:44-42:04 This is a question for both of you because the food industry has spent an awful lot of time, money, and research into making foods addictive. And I’m talking about snack foods. I’m talking about this vast majority of foods in the middle of the supermarket that is so tasty that you just want more and then more still. And a lot of those foods have chemical names that you couldn’t possibly pronounce or understand. And they’re high in salt and they’re high in sugar and they’re high in all kinds of seed oils, which is a particular issue for us because we’ve just recently talked to some experts who say those seed oils may be pro-inflammatory and therefore increase the risk for heart disease and diabetes and maybe even cancer. So in a sense, you’re fighting this massive and very successful food industry that has packaged foods to taste great. And we, as people, are always susceptible to yummy tasting foods, even if they’re not good for us. How do you combat that with the food is medicine idea? Dr. Seth Berkowitz 42:05-44:23 So I think this is a great question, and I think it’s worth thinking about both the problems and the solutions at multiple levels. A lot of what we’ve been talking about in food as medicine I see as essentially treatments, things that come in after the fact, after people are already existing and have lived maybe a lot of their lives in an unhealthy food environment, in a society where economic resource distribution is not very equal, and so they experience food insecurity and things like that. And you’re trying to use food as medicine interventions to treat the consequences of that, or at least mitigate them to the extent you can. And these are effective treatments for that. But as you said earlier, you know, we all know that prevention is probably better than treatment. And so then you get into this higher level question of how do you sort of create a system of social relations, a structure of society, so that people are in environments that promote their health. You know, we focus, I think, too much in medicine on individual solutions. The individual should resist with willpower those tasty treats or those kinds of things. And to a certain extent that that can happen. But I think we also need to think structurally. Why is it that those foods, which have a lot of different labor inputs and other things like that, why are they more affordable than foods that seem simpler to produce in some ways, right? You know, an apple or grapes or something like that. Why is it that so many people are, you know, struggling to make ends meet and really have to choose, you know, to get their 100 calories through soda rather than 100 calories of broccoli, because it’s a lot cheaper to get your calories through soda than it is through broccoli. And so then these structural questions, I think, really get at bigger questions around social policy and how you might use social policy to promote people’s health overall. And that will involve an element of programs that, what you might call incomes policy, distributing resources so that people have income they need to be healthy. That will involve elements of policies that target what you might call the commercial determinants of health, the ways that food industry and other industries will create products and affect people’s health in that way, and I think really is a bigger picture question that’s ultimately the really important question to be asking for what you might call population health, the overall health of the American people. Joe 44:25-44:26 Peter, thoughts? Peter Skillern 44:26-45:19 What problem are we solving here? Are we solving the commercial production of food and how that’s regulated and distributed? Or are we looking for this particular food as medicine about helping to address people’s individual health and then scaling that up so that it can affect our population health? That we’re using the health care system for payment, for enrollment, for treatment. And that’s a really more narrow problem to solve. And I think that one of the challenges our food is medicine movement faces is there are so many interrelated challenges that we have. We’ve got to stay focused on what are we solving today for this type of initiative. So through providing a food is medicine food subsidy, we’re enabling individuals at scale and millions of folks to be able to make better choices. But we still have to make their… they have to make those choices and the industry has to respond. Joe 45:20-45:21 And who’s paying? Peter Skillern 45:21-45:44 Well, so in the publicly insured healthcare space, it’s Medicaid and Medicare and the Veterans Administration. But the majority of people are covered by commercial plans through their employers or through the American CARES Act. So that’s kind of different payers all have different standards for who will pay for this, underneath what conditions. Joe 45:45-46:01 Because you kind of could imagine an insurance company saying, you know, if I can keep people out of the emergency department, I’m going to save money. And if it’s what, $40, $50 a month, is that how much you said for your debit card? Peter Skillern 46:01-46:01 That’s right. Joe 46:02-46:23 That’s a huge investment. But I’m also wondering about the government. You know, we’re continuing to hear, well, we need to slash these programs. And what will happen when that is implemented, especially with a food is medicine type program like yours? Peter Skillern 46:23-47:07 Yeah. We say that we’re trying to meet the business regulatory and health care requirements of the health care sector. We also have to meet the political requirements, which is a broader issue. We think that this intervention addresses some concerns around efficient use of resources, emphasizing individual choice, showing greater returns. And as this research, it’s evidentiary that it’s making a difference. This food is medicine movement is not a simple task. It is a cultural change. It’s a political change. It’s a technology change. It’s a medical practice change. It’s an individual change. And so let’s recognize the complexity of it and stay focused on those things that we can affect through this strategy. Joe 47:08-47:37 What about kids? Because, Dr. Berkowitz, you said prevention. And prevention is always better than trying to catch up and deal with treatment. I think a lot of school lunches are, you know, what are tasty, you know, pizza, macaroni and cheese. Maybe the broccoli is not as popular. How do we begin to get kids involved in the food is medicine movement? Dr. Seth Berkowitz 47:37-49:38 I think getting kids involved is very important, but I’ll actually point to the National School Lunch and School Breakfast Program as an area where we’ve made a lot of improvements, actually. So throughout the 2010s, there’s been a change in the nutritional standards for school meals. Again, anytime you’re cooking at large scale for lots of people on, you know, very tight budgets, things might not be, you know, exactly what everyone would want. But a lot of studies show that the meal that kids get at school is often the healthiest meal of the day they get compared with home cooking. And the bigger picture point, even though I think there is still room to improve, is that there has been real progress there. And so it’s been a win in a lot of ways and points to the fact that if we do make a concerted effort to change these things, we can improve the nutritional quality of the food that’s being provided. And I think there’s a lot that the food is medicine movement can learn from the way that policy has been used in the national school lunch and school breakfast program. But to your larger point of, you know, should be should kids be involved in food is medicine programs? I think there’s a lot of potential for that. However, the evaluation of it, I think, needs to be a little bit different for an adult with heart failure, or someone who is currently on dialysis, their short-term consequence of eating an unhealthy diet is very high. And so the healthcare costs associated with that in a couple months span is very high. And so if you’re doing a study that follows people for a few months, you’re likely to be able to see a difference between a healthier diet and a less healthy diet. Kids, you’re talking about years, are really preparing them for adulthood and maybe their older age and things like that. And so if you use the same standards and say, well, I want to, you know, if I’m going to, you know, choose the adult program over the child program because the adult program saves me money in six months, but the child program doesn’t, you’re going to, you know, not take advantage of what could be a very large long-term impact because you’re being a little bit short-sighted about it. So very important to include children in food as medicine interventions, but you also have to think about the specifics and the nuance of the situation when you’re evaluating it. Peter Skillern 49:39-49:55 One area that we found is we did a pilot with Atrium in Mecklenburg County with expectant mothers, you know, and the response that mothers gave as far as the impact of food security on themselves and their newborns, you know, it was pretty tremendous. Terry 49:57-50:10 And this is a wonderful place to do an intervention because expectant mothers mostly are very interested in doing whatever they can to promote the health of their growing fetus. Peter Skillern 50:10-51:01 And it’s a particular area where the insurance is involved, right, with medical experience. Another population of youth are those in foster care who are often covered by Medicaid insurance underneath the behavioral health sections. That’s a Medicaid expense. 70% of young women 13 to 21 become pregnant underneath the foster care system, right? Food insecurity is extremely high among foster care children. There’s an area for where we can provide Medicaid-provided food assistance that will help the direct health outcomes of foster care children. So there are different ways of looking at this problem of how can we intersect between the health care sector, insurance, the providers, and the patient. You know, it’s got to work for all three, and I think we can solve those problems. Terry 51:01-51:19 Dr. Berkowitz, I’m wondering how the food is medicine movement would compare or compete or possibly complement the conventional pharmaceutical approaches to problems like you have diabetes, you want to get your A1C level down, or how about GLP-1s? Joe 51:22-51:25 Explain GLP-1s, Dr. Berkowitz. Dr. Seth Berkowitz 51:25-52:07 Sure, yeah. So GLP-1s are a group of medicines that work in receptors for a hormone called incretins–the hormone is called incretin–and they have a lot of effects on the body, but in particular, they have large effects on appetite and satiety and tend to result in a large amount of weight loss, and for people with diabetes, large drops in the blood sugar. And so have been a really important category of medicine over the last decades or so, the last about a decade, and really kind of taking off in the last few years for use beyond people with diabetes, but also as a weight loss medication. Terry 52:08-52:17 And so the question is, food is medicine. How does it interact with the use of these potent pharmaceuticals? Dr. Seth Berkowitz 52:17-53:31 Yeah, I think there’s a lot of complementarity to it. And there are a few issues involved. The GLP-1 medicines are very powerful, but they’re sort of blunt appetite suppressants. And so the quality of what you eat, even though you’re eating less overall, is still very important. And if you only use GLP-1s but don’t pay any attention, let’s say, to the quality of what you’re consuming, you know, maybe you’re only having 1,200 calories a day, but it’s only a milkshake or something like that, then that’s going to have bad health impacts, even though there might be some benefits from the weight loss overall. The actual components of what you’re consuming will have health impacts in other ways. And so I think there’s complementarity in using food as medicine interventions for people who are on GLP-1s to promote better diet quality for the foods that people are eating. A number of people have side effects with GLP-1s and so can’t tolerate them long-term. And so food as medicine interventions might be an alternative. And a lot of people may want to stop taking a GLP-1 at some time. They might have lost the amount of weight that they’re looking to lose and would like to sort of stay at that weight or, you know, slow the regain of weight to the extent possible. And so food is medicine interventions can be helpful in that situation as well, I think. Joe 53:31-53:57 I’d like you both to look into your crystal ball and say, okay, if we were in charge, if they gave us a lot of money to make food is medicine kind of the primary way that both the public as well as health professionals would look at this whole process, what would the future look like for you and how would you implement it? Terry 53:57-53:59 And you each have one minute. Joe 54:01-54:03 Starting with you, Dr. Berkowitz. Dr. Seth Berkowitz 54:03-55:03 Okay. Well, maybe this will be my curveball. So I think food as medicine programs are very important and I think it’s important that they have a place in the healthcare system. But I really don’t think that we can lose sight of the question of why are food as medicine programs needed for so many people. And so if I really have a lot of control and everything, though, so if I really have the control that you’re giving me, while one aspect of that would be making sure that evidence-based food as medicine interventions are available as insurance benefits for people, another piece would be to really sort of question, well, why is it that, you know, so many people find it so difficult to follow a healthy diet? And are there things that we can do to address income and resource distribution in the U.S.? Are there things we can do to address commercial determinants of health? Are there things that we can do to address the reasons that people find it difficult to follow a healthy diet so that maybe they don’t even need a food as medicine intervention in the first place? But if they need it, I do want it to be there. Joe 55:04-55:04 Peter? Peter Skillern 55:06-56:22 Again, I focused around where the health care sector aligns with food support, around the health outcomes, around the financial incentives. You know, as a person who’s trying to address poverty at scale, I certainly support a broader safety net, right, to help people purchase that. But within that, where does health care find its motivation? And it’s motivated by patients asking for it from providers like the clinicians saying this is needed. There is research that shows it’s impactful. And for health insurers to say we have an incentive to do this at scale. And it may not be for everyone. Even a small population as a percentage, when you scale it across all of America and our population, we serve millions of people. Those with uncontrolled diabetes or cardiovascular failure or even smaller issues. It makes a difference at an enormous level. So I’m not looking for the revolution. I’m looking for the incremental difference that we can make in people’s lives, but do it at a systems level across this country. So I think food is medicine has huge potential for both political and practical reasons.
