    Show 1482: Are Your Kidneys in Trouble? Two Tests Could Tell You

    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.

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.

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

    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.

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.

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

    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.

    Show 1446: The Science of Strong Bones: Lifestyle, Medication and Movement (Archive)

    Are you concerned about your bone health? Do you worry about osteoporosis? According to the CDC, more than 10 million Americans have low bone density that makes them more vulnerable to fractures. For many older people, a fracture can be devastating, reducing mobility and possibly even leading to death. What does the latest medical science tell us about how you can maintain strong bones? 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.

We have added extra information to these notes, but not to the interview itself. Strong Bones You may have seen Halloween skeletons or even chewed the meat off a bone that you then dropped on a plate with a clatter. No wonder we usually think of bones as hard, unchanging objects. Dead bones are. But living bones are quite different. Strong bones are constantly undergoing change. Scientists call it remodeling. One set of specialized cells, osteoclasts, breaks bone tissue down and recycles it. Another set, the osteoblasts, builds bone back. Ideally, their activities are in balance. But if the osteoclasts start to get ahead, as they tend to do while we age, that can weaken bone. The result is low bone mass, known as osteopenia, or even serious bone loss called osteoporosis. This puts a person at risk for fractures. Who Gets Osteoporosis? Osteoporosis may have been less common a hundred years ago or more, when many people had to do manual labor that put stress on their bones. That helps for strong bones, so today’s sedentary lifestyles can undermine bone health. Although we think of osteoporosis as typically affecting postmenopausal women, men can lose bone mass too. Medications may contribute to the risk for bone loss. Steroids such as prednisone or methylprednisolone are especially risky if taken for a long period of time. Androgen deprivation therapy for prostate cancer is a risk factor specifically for men. Wait–MEN Can Get Osteoporosis? Q. My husband and I have two friends with significant disability largely due to spinal fractures as a result of osteoporosis. One man was always an avid exerciser, including running marathons. Both men are over six feet tall and have always appeared to be muscular. My husband is shorter and is physically active, playing tennis and going to the gym regularly. Because of our friends’ bone issues, I advised him to request a DXA scan to assess his bone health. The nurse practitioner told him that it was not recommended for men. I am still concerned that he may be at risk for osteoporosis. Are there medical studies that determine the risk factors for men? A. The nurse practitioner was mistaken. Men can develop osteoporosis, as your friends discovered. Many medical guidelines recommend that men over 70 be tested with a DXA scan to assess bone health. If your husband has low testosterone levels or has taken medications such as prednisone, he could be at increased risk for a fracture. He would be prudent to have the assessment. Diagnosing Osteoporosis Doctors assess bone mineral density with imaging called dual-energy X-ray absorptiometry, or DEXA for short. Then they compare the results on the scan to the results they would expect from a 30-year-old person. Results more than 2.5 standard deviations from that could result in a diagnosis of osteoporosis. A person who experiences a fracture without trauma, such as falling from standing height, is also suspected and often diagnosed with osteoporosis. Non-Drug Approaches to Strong Bones: People who want to keep strong bones need to focus on exercise. High intensity exercise can be helpful, but brisk walking may be enough. Tai chi and yoga are also popular. If you have been diagnosed with osteoporosis, be sure to check in with your doctor before you start a new exercise program. Building balance and core strength without increasing your risk of a fall (and thus a fracture) would be ideal. Our guest expert, Dr. Kendall Moseley, says the jury is still out on technology such as vibrating platforms, weighted vests or vibrating belts. More studies should show how valuable these could be. Following a diet that supplies adequate protein, vitamin D and calcium is also crucial. If you must take a calcium supplement, calcium citrate may be well tolerated and absorbed. How Do Doctors Treat Osteoporosis? Physicians prescribe several different types of medications to help curb bone less and perhaps even build it back. Some of the oldest and least expensive are the bisphosphonates such as alendronate (Fosamax). These slow bone break down and give the osteoblasts a chance to catch up. They can be hard on the digestive tract, though, and they have been associated with a few rare but alarming side effects: jawbone deterioration and atypical thigh bone fracture. Most people seem to do well on them. Doctors generally prescribe them for up to five years. Did You Forget Evista? Another type of osteoporosis medicine is called raloxifene (Evista). It is appropriate only for women, because it is an estrogen modulator. It acts like estrogen in the bones and reduces bone loss. In the breast and uterus, it opposes estrogen activity. Raloxifene does double duty in reducing the risk of breast cancer as well as osteoporosis. Like all drugs, though, it has some worrisome side effects. It can increase the risk of blood clots that cause deep vein thromboses and strokes. What About Prolia? Denosumab (Prolia) is a monoclonal antibody that also interferes with osteoclasts. That is how it improves bone density. One thing to keep in mind about Prolia is that stopping it requires careful planning and backup medication. Otherwise, a patient can lose all the bone that was built rather quickly and may suffer debilitating fracture. This Week’s Guest Kendall F.

If you don’t recognize this generic drug name, you probably do recognize the brand names. Ozempic for type 2 diabetes and Wegovy for weight loss. Both these medications are self-administered injections, but not everyone is enthusiastic about needles. There’s also an oral form of semaglutide called Rybelsus. The FDA has approved it for treating type 2 diabetes six years ago, and so far it has mostly gone under the radar. A new study published in the New England Journal of Medicine demonstrated that oral semaglutide at 25 mg a day helped people without diabetes lose significantly more weight than placebo. The randomized trial included more than 300 volunteers and lasted approximately a year and a half. This could be good news for people who have trouble accessing injectable semaglutide or keeping it

The podcast will be available on Monday (July 20, 2026) Do You Need a Sleep Reset? Why is sleep so important for good health? Our guest is a sleep medicine specialist who uses a metaphor of Disneyland. Crucial maintenance on the theme park happens at night, when there are no visitors. Streets are cleaned, flower beds are weeded, and rides are inspected and, if needed, repaired. None of that can happen while the park is open for business. Our bodies and brains also need time for maintenance and repair, and some of that happens while we are sleeping. When we don’t get the rest we need, we may find ourselves at increased risk for diabetes, cardiovascular problems, cancer, cognitive challenges and even premature death. Unfortunately, anxiety about not sleeping can keep people awake all on its own. How can people break that cycle? We’ll also discuss ways that people can get help avoiding screens at night. That is an important part of a sleep reset. Blue light from the screen signals the brain to be alert instead of relax. Scrolling social media can often be emotionally upsetting, which also makes it more difficult to fall asleep. Is Your Diet Keeping You Awake? Most of us recognize that a big midnight snack, á la Dagwood Bumstead of the Blondie comic, is probably not conducive to sleeping well. How does nighttime eating affect our circadian rhythm? Are there diets that we should avoid because of their impact on sleep? Dr. Seheult describes a study in which volunteers had their sleep stages monitored closely during the time they were consuming different diets (Obesity, July 2023). When they followed a high-fat, high-sugar diet, it disturbed the pattern of their brain waves during what should have been restorative sleep. How Do Sleep Problems Affect Eating Habits? A lot of us are aware that when we are sleep deprived, we are more inclined to become hangry and we may be less discerning about what we eat. A recent study shows that the sleep deprivation can have an effect even if it is fairly mild and short-term. Scientists recruited people who normally sleep seven to eight hours a night and asked them to stay up an extra hour and a half (Annals of Internal Medicine, July 7, 2026).  During the six weeks of that part of the experiment, people were less active during the day. They also ate more, so they gained about a pound, on average, during those six weeks. Presumably, disrupting sleep for a longer period of time would result in greater weight gain and metabolic disruption. Would a Ketogenic Diet Help with a Sleep Reset? A ketogenic diet, in which the body relies on ketones rather than glucose for energy production, may be helpful. In particular, fasting overnight for at least 14 hours helps the body do what it must during sleep time. To figure out when you should stop eating, identify when you usually start to feel sleepy. That should be your bedtime. Having your last meal of the day about three hours before that will generally offer enough time for digestion so that you don’t experience reflux in the middle of the night. Morning Light and Afternoon Naps Your sleep reset may depend on getting your own circadian rhythm to synchronize with the rest of the world. That is where early exposure to morning light comes in. It’s beginning to feel a bit like The People’s Pharmacy is on repeat: get morning light exposure! It sets your system up for feeling awake and alert during the day and starting to feel sleepy as the light fades in the evening. Obviously, this is most helpful for people who work during daylight hours. Those working overnight shifts would have to organize their days differently. People who have trouble falling asleep may be tempted to take a nap in the afternoon to make up for the lost sleep. That could be a mistake, as it relieves the sleep pressure that helps people fall asleep without trying. Learning to Fall Asleep If you interact with parents of very young children, you may have heard of sleep training. People have strong feelings about this, both pro and con. Adults rarely need sleep training, though. What we are more likely to need is “not-sleeping un-training.” Too many people approach the bedroom as though it were a stage, and sleep is the performance. No wonder they may develop some performance anxiety about sleeping! Other individuals have learned to associate the bedroom with tossing, turning and watching the clock. Consequently, their bodies tense up instead of relaxing when they get between the sheets. There is no easy quick fix for this problem, but cognitive behavior therapy for insomnia has been proven effective for most people. How About PM Pain Relievers? Even though there isn’t an easy fix for sleep troubles, many people want one. They reach for the PM pain reliever and hope it will offer them a good night’s sleep without a prescription. The “PM” part of that pain reliever is an old-fashioned antihistamine called diphenhydramine. You might be more familiar with its brand name: Benadryl. You’ll also find it in Tylenol PM, Advil PM and all the other PM meds because it tends to make people feel drowsy. What’s wrong with that? To start with, it isn’t clear that it remains effective after a week or two. In addition, people with restless leg syndrome often find that it makes their condition worse. Other folks report that diphenhydramine can result in an unpleasant “hangover” the next day, in which they feel drowsy though not asleep for a good part of their waking hours. What Wakes You Up at Night? If your sleep problem is waking in the wee hours and having trouble getting back to sleep, you should consider the possibility that you have sleep apnea. The REM sleep of those early morning hours is not as deep as some other sleep stages. Consequently, an alarm signal from your brain saying you haven’t taken a breath for 20 or 30 seconds may be more likely to wake you. Sleep apnea may be treated by providing air so that the pressure props the collapsing airway open. We discuss this in greater detail along with a new alternative to a CPAP machine in the podcast for this week.

    Show 1479: Must You Shun the Sun to Save Your Skin?

    When sunny summer days come around, it makes some dermatologists shudder. They would prefer we behave like bats and hide in caves until nightfall. Failing that, they stress the importance of always applying (and re-applying) high SPF sunscreen, wearing sun-blocking clothing with long sleeves and keeping a big-brimmed hat firmly on the head. A beekeeper’s outfit might be perfect. But must you really shun the sun completely to save your skin? Our guest describes how to practice moderation safely. He also explains why some people are addicted to sunshine, while others are allergic to 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 or get the live stream at 7 am EST on Saturday, July 11, 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 July 13, 2026. Can You Really Be Addicted to Sunlight? Dermatologists do their best to discourage people from using tanning beds. They describe the damage that ultraviolet light can cause, ranging from wrinkles to skin cancer. For some people, though, those arguments just don’t make a difference. Our guest, Dr. Steve Feldman, conducted a study several years ago. The volunteers were accustomed to using tanning beds. In the study, there were two beds, one with the usual ultraviolet light and the other, identical in appearance and temperature, had its UV blocked. After a session in each bed, volunteers were allowed to choose their bed for the last session. They almost invariably chose the bed with the active UV. To follow up, the researchers administered naltrexone, the opioid-blocking medication. When volunteers had taken it, they were no longer able to distinguish which bed was active. It seems that, for these people, ultraviolet light activates pro-opiomelanocortin, which in turn triggers the production of natural opioids called endorphins. Further research imaging the brain during tanning sessions confirmed that the UV exposure was activating areas of the brain associated with pleasure (Psychiatry Research. Neuroimaging, May 30, 2016).  Dr. Feldman and a colleague found that excessive indoor tanning is similar in pattern to substance use disorders (Journal of Cutaneous Medicine and Surgery, May-June 2025). Can You Save Your Skin and Still Enjoy the Outdoors? Dr. Feldman offers advice on avoiding sunburn that is tempered with this fact from epidemiology: people who go out in the sun live longer (International Journal of Environmental Research and Public Health, July 13, 2020).  The goal here is not to shun the sun completely, but rather to exercise enough caution and good judgment to avoid burning your skin. (Who wants to burn, anyway? It hurts, and it looks bad.) Timing your sun exposure carefully is crucial to save your skin from sunburn. You may also be interested in the new sunscreen ingredient the FDA just approved, bemotrizinol. What Can You Do About Heat Rash? When the weather gets hot and bodies get sweaty, heat rash becomes a common complaint. Sweaty skin may develop bumps that can sometimes be very itchy. What do you do to ease the discomfort? If you can cool the skin off, it might help a lot. Of course, people may also suffer from other types of rash. Babies get diaper rash. Women sometimes experience under-breast rash, just as men may develop jock itch. Zinc oxide ointment can often be helpful for these types of rash. Managing Psoriasis Psoriasis is one of Dr. Feldman’s special research interests. The red scaly plaques of this skin condition have raised borders. They look a lot like a fungal infection, but there is no fungus present on the skin to cause them. Something else seems to trigger the skin’s immune system to react along the same pathways as if there were a fungus. Most of the time, psoriasis is mild enough to manage without costly medications. It actually responds very well to ultraviolet light exposure. UV downregulates the immune system’s over-response. While many dermatologists offer UV exposure within their office walls, in the summertime patients could get exposure to sunlight outdoors. This is practical if they avoid the middle of the day, when they might get burned. Another option? Tanning beds also offer an easy way to calibrate the appropriate amount of UV exposure to save your skin from psoriasis. (Most dermatologists don’t approve of this one, so don’t tell.) One other practical but unorthodox tip for dealing with mild psoriasis. OTC cortisone may not be strong enough to help heal up a red spot. But you could buy Flonase nasal spray or a generic version, fluticasone, over the counter. Spray it on your skin and appreciate the relief. In fact, this could work for a mild case of poison ivy or other skin irritation as well. Severe cases still need a dermatologist’s care. What to Do About Atopic Dermatitis Atopic dermatitis is the medical term for eczema. People with allergies or asthma also appear to be more vulnerable to eczema. Dysregulation of the immune mediators interleukin 4 (IL4) or IL13 may be responsible. This condition may appear in a mild form, which can be readily managed, or a more severe form that might require prescription medication. A topical corticosteroid such as triamcinolone will often clear it up. Or you could try spraying on some Flonase nasal spray for a cost-effective low-key approach. Those will actually help the majority of people with mild eczema. Using mild soap rather than detergent-based body wash, moisturizing well and following an anti-inflammatory diet are the pillars of home management. People with more severe atopic dermatitis covering a large portion of the body may need powerful prescription medication rather than topical steroids. Trying to cover so much skin with steroid would probably result in side effects from the cream. Dupixent (dupilumab) is a relatively new self-injectable medication that blocks IL4 and IL13. It works well for most people with atopic dermatitis and has a good safety profile. Certain other drugs in this category, such as Skyrizi (risankizumab), are also pretty safe but very pricey. Stelara (ustekinumab), has been around longer. Biosimilars for Stelara have been approved and are more affordable. Ustekinumab blocks IL12 and IL23. TV ads tout other medicines for this condition as well. Rinvoq (upadacitinib) is three or four times more effective than Dupixent, but it is also super expensive. It is a Janus-kinase (JAK) inhibitor. Xeljanz (tofacitinib) is another potent prescription JAK inhibitor, but it carries an elevated risk of heart attack. Beware of Bug Bites Another summer skin hazard is bug bites. Here unquestionably the best approach to save your skin is avoidance. Appropriate clothing is key. (That beekeeper’s suit will come in handy here again.) Dr. Feldman recommends spraying DEET on your pants legs, socks and sleeves rather than directly on your skin. If there are grasses or brush where you have walked, run or played, a tick check immediately upon coming inside is critical. Can AI Help Patients with Skin Problems? It doesn’t make sense to tell people to stay off the internet. Some searches can be quite helpful and guide patients in asking their dermatologist the right questions. Dr. Feldman is enthusiastic about DermNet, a New Zealand dermatology website. https://dermnetnz.org  Joe and Terry recommend SkinSight. This Week’s Guest Steven R. Feldman, MD, PhD, is Professor of Dermatology, Pathology, and Social Sciences & Health Policy, at the Wake Forest University School of Medicine.  His research has been published in over 1,000 peer reviewed, Medline-referenced articles. Expertscape.com ranks Feldman among the top experts in the world on psoriasis, acne, dermatology, and treatment adherence.

    Show 1412: Beyond Amyloid: The Science That Could Change the Course of Alzheimer Disease (Archive)

    This week, we look at the new pharmaceuticals that the FDA has approved for treating Alzheimer disease. Although they are effective at removing amyloid plaques from the brain, they don’t seem to help patients function better. Is it time to turn away from an exclusive focus on amyloid to consider other factors that might affect cognitive decline and change the course of Alzheimer disease? 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 EDT on your computer or smart phone (wunc.org).

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 July 6, 2026. Changing the Course of Alzheimer Disease Even though pharmaceutical firms have spent billions of dollars developing drugs to reduce amyloid in the brain, they haven’t changed the course of Alzheimer disease. Perhaps we need to be looking beyond amyloid at other risk factors. Dr. Dale Bredesen says he and his colleagues have identified more than 36 risk factors. He asserts that when these these are addressed, people can slow or sometimes even reverse their cognitive decline. According to Dr. Bredesen, Alzheimer disease is multi-factorial and it needs a multi-pronged approach. Considering Physiology Instead of Pathology The plaques and tangles that are characteristic of the brain disease first identified by Alois Alzheimer more than 100 years ago only show up in pathology slides. Past studies have hinted that some individuals who have plaques or tangles in their brains don’t have serious cognitive difficulties. Dr. Bredesen urges us to look beyond amyloid pathology and use a physiology lens. What are the main drivers of problems? Energetics Our bodies need to make, use and transfer energy efficiently. That involves the mitochondria, the energy factories within the cells. Nutrition is also critical here, as missing vitamins can block appropriate metabolism. The cardiovascular system is also crucial for the transfer of energy within the body and to the brain. Sleep apnea, which interferes with oxygen uptake overnight, is another big culprit. Inflammation Inflammation in the brain or even elsewhere in the body puts a huge strain on the neurons. Identifying and removing the sources of inflammation is important in treating someone struggling with cognitive problems. Where is the inflammation coming from? It might be an infection. Treatment can make a difference there. It might be dietary, in part. Changing the diet could change the course of Alzheimer disease. Wouldn’t that be worth the effort? Toxicity Heavy metals such as lead or mercury are definitely neurotoxic. However, other substances can also put neurons at risk. Toxins produced by mold are common and very difficult to treat. Additional Factors to Consider There are at least three additional categories that should be considered. Do we have the essential ingredients to create the neurotransmitters we need? One example would be choline for acetylcholine, an essential neurotransmitter that may be in short supply in Alzheimer disease. Most American diets are not rich in choline. Second, how are the neurotrophins doing? These are substances such as BDNF, brain-derived neurotrophic factor. It supports the growth and differentiation of neurons. Third, and possibly most common, is chronic stress. Occasional acute stress is expected and shouldn’t be considered harmful. But chronic stress can damage neurons and make it harder to think even if your neurons are not damaged. High cortisol levels are associated with brain atrophy, which is a clear indication of damage. Fixing the Leaks Dr. Bredesen uses a metaphor of the brain as a house with a leaky roof. If you have a lot of places where the roof leaks, you need to fix all of them to stay dry. But your roof may leak in different places from your neighbor’s roof. Finding the weaknesses and addressing them with personalized medicine is key to changing the course of Alzheimer disease, in Dr. Bredesen’s opinion. It may require attention to diet, exercise, sleep (with adequate oxygen saturation), stress management, brain training, detoxification and possibly supplements such as omega-3 fats or vitamin D. You can learn more from his books and his recent publication in Biomedicines (Aug. 6, 2024). This Week’s Guest Dale Bredesen, MD, is an internationally recognized expert in aging and neurodegenerative diseases. He is the Senior Director of Precision Brain Health at Pacific Neuroscience Institute, and former Professor of Molecular and Medical Pharmacology at UCLA. Dr. Bredesen is also the founding President and CEO of the Buck Institute for Research on Aging and the Co-founder of MPI Cognition. Dr. Bredesen is the author of the New York Time’s best seller The End of Alzheimer’s: The First Program to Prevent and Reverse Cognitive Decline and The First Survivors of Alzheimer’s: How Patients Recovered Life and Hope in Their Own Words.

    Show 1478: The Outdoor Prescription for Fighting Dementia, Depression and Heart Disease

    Too many of us are spending our days staring at screens. Little screens on our phones, big screens on the television, medium-size screens on our computers at work. Our modern lifestyles mean that we spend the vast majority of our time indoors–93%, on average. What is the time inside doing to our health? Is there an outdoor prescription to reverse dementia and depression? 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, June 27, 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 stream on this post starting on June 29, 2026. What Is Our Indoor Time Doing to Us? Humans used to spend a lot of time outside and had their circadian rhythms synchronized with sunlight. Living indoors as most of us do can disrupt that natural rhythm. Bright indoor lighting as well as our favorite screens in the evening can make sleep more elusive. Another consequence of focusing on screens rather than on a distant horizon of land, sea or sky is an increased risk of nearsightedness. Beyond that, screen exposure can increase the chance of brain fog, insulin resistance and immune system abnormalities. If you are spending all your time inside, your body may process that as captivity and begin to rebel. The Outdoor Prescription Dr. John La Puma pioneered culinary medicine, making the connection between what we eat and the state of our health. His analysis of the research indicates that spending just 17 mindful minutes outside each day can help reverse the damage we suffer from living indoors. He offers seven types of outdoor prescription, starting with morning light. Greeting the Sun as the Day Begins Dr. La Puma encourages us all to start our day by stepping outside for at least a few minutes under the open sky. Before coffee, before screens, morning light gets us off to the right start and helps us sleep better at the end of the day. That light exposure, even on an overcast day, helps us with deeper sleep at night. Deep sleep is critical for maintaining the brain with the glymphatic system as well as for bolstering the immune response. Before checking your email or your social media, perhaps while the coffee is brewing, make it a point to step outside for a few minutes. If that is too difficult, standing in the doorway or just looking outside through a window screen (not glass) may be enough. Bright morning light exposure is helpful in treating major depressive disorder (JAMA Psychiatry, Jan. 2016). Although the study utilized standardized indoor lights, natural light outside is brighter, even on a cloudy day. New research shows that bright light during the day reduces the risk of dementia among older people (General Psychiatry, June 24, 2026). The benefit was especially clear for those who spent more time in brighter light (at least 5,000 lux) such as one would get on an overcast day. It was even able to mitigate some of the risk associated with APOE4 genes. What Is Forest Bathing? Another practice in Dr. La Puma’s outdoor prescription pad is forest bathing. This idea comes from Japan. Spending time outdoors in a forest environment is extremely healing. It can help modulate the immune system, lower blood pressure and counteract stress. Forest bathing does not require a huge investment of time, either. One Japanese study found that spending just two hours a month in a forested environment can lead to lower blood pressure and reduce techno-stress. A review has found forest bathing beneficial against stress and burnout (International Journal of Environmental Research and Public Health, July 28, 2017). https://pubmed.ncbi.nlm.nih.gov/28788101/ No Forest? No Problem Many people do not have an actual forest handy. Dr. La Puma describes his outdoor prescription for Sarah, who felt stuck inside her city apartment all the time while she cared for her elderly mother. What he prescribed for her was mindful time in the courtyard of her building, starting with very short periods of five to ten minutes. Gradually her heart rate slowed and blood pressure lowered and she began to recover from some of the chronic problems she had been suffering. Forest-bathing doesn’t really require a forest. One tree, or in a pinch, a shrub, can be pressed into service. Meet Your Friends Outdoors There are few things better than spending time outdoors. One outdoor prescription that improves on spending time in nature by yourself is spending some of that outside time with friends. Walking, playing tennis, going for a picnic all help your system recalibrate. Human friends are important, but animals such as dogs or horses can also contribute to our well-being (as we contribute to theirs) when we spend time with them in a natural space. Taking Your Physical Activity Outside We all have heard how important it is for us to stay active if we want to maintain good cardiometabolic health, diminish our risk of depression and enhance our chances of staying cognitively sharp. There are advantages to outdoor activity that include but go beyond the benefits of exercise. You can accomplish the same amount of exercise with less perceived effort. In addition to light, and possibly horizons, you also get beneficial microbial exposure and a lot of joy. Gardening as an Outdoor Prescription A healthful diet begins with healthy organic soil. Gardening is a great way to experience this for yourself. We asked about people who do not have space for a backyard garden and heard about Greg, who learned to garden starting with a single basil plant indoors. Minimum Effective Dose for the Outdoor Prescription Dr. La Puma tells us that the minimum dose to get the benefits of being outdoors is just 17 minutes a day. That’s not very much compared to all the time we spend inside. This Week’s Guest Dr. John La Puma is a board-certified internist, trained chef, and regenerative farmer who pioneered the Culinary Medicine movement. He is now leading the charge behind Outdoor Rx, the evidence-based response to the indoor epidemic.
