The People's Pharmacy Podcast

If you had to name one thing that could contribute to better health throughout the lifespan, what would it be? We think exercise, or at least physical activity deserves the top spot. Yet in 2025, fewer than half of adults met the guidelines for aerobic physical activity. And less than one-quarter were doing both aerobic and muscle-strengthening exercises on a regular basis. Perhaps your doctor should prescribe exercise. What could we expect as the benefits? 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.

Please consult your healthcare provider before making any changes to your medical care or treatment. Would Your Doctor Prescribe Exercise for Depression? Earlier this year, the Cochrane Collaboration published a review of 73 randomized clinical trials of exercise as a treatment for depression (Cochrane Database of Systematic Reviews, Jan. 8, 2026). Most of these compared physical activity to antidepressants or to psychological therapy for depressed patients. Some of them compared the exercise prescription to no treatment or wait list. Comparing exercise to no treatment revealed an advantage for exercise, although the quality of the trials left something to be desired. Ten trials compared exercise to psychological therapy. In addition, five trials weighed exercise against antidepressant medication. Neither comparison showed a clear tilt for or against exercise as a superior intervention against depression. Exercise in the Cancer Center Dr. Claudio Battaglini of the University of North Carolina at Chapel Hill was not surprised by this finding. The exercise program he oversees for cancer patients often results in lifting their spirits as well as improving their health. That may help explain the very high adherence in his program. Will Physical Activity Reduce the Risk of Cancer? According to a review of the evidence, regular physical activity can reduce the number of people who die prematurely. In addition, it helps with weight control, quality of life and bone health. Older people are less likely to fall or experience declining cognition if they exercise regularly. The review found that physical activity improves quality of life and promotes emotional benefits (European Journal of Cancer Prevention, Jan. 1, 2025). If oncologists should prescribe exercise, don't cancer patients deserve to have their insurance company cover the cost? Insurers rarely blink twice at cardiac rehab. Although cancer rehab is also super-helpful, insurance companies often don't choose to pay for it. What Role Could Coaching Play in Guiding Physical Activity? Lots of doctors tell their patients to get more exercise. The patient wants to and intends to, but perhaps they just don't know how. What activity should they choose? What is the proper technique? How often and how much do you need to move? All these questions can be answered by a coach. The coach will take into account your objectives and preferences as well as your prior experience. What do you love doing? Are there any moves you should avoid to reduce the risk of injury? That's why when doctors prescribe exercise, they should include coaching to provide this sort of guidance. If Doctors Prescribe Exercise, Will That Help Motivation? Many of us know we should be active, but we don't always follow through. How can we get motivated to move? According to Dr. Jordan Metzl, the first step is to find something you love doing. For Joe, for instance, having the doctor prescribe exercise of runniing a mile a day is not going to work. But he'll cover much more than a mile–and quickly–if he is playing a competitive game of tennis. Joe loves tennis. Terry is not a runner either. On the...

Hospitals can be pretty overwhelming. Sometimes you may feel like you need a map to find your way around the maze, not to mention a trusty guide to get you to the department or health professional that could actually help you overcome illness. In addition, being hospitalized often means being deprived of fresh air & sunlight. Could that be a mistake for proper healing? 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.

Striving for Person-Centered Care Wouldn't it be great if healthcare facilities were specifically designed around the individuals they are supposed to serve? Fifty years ago, a group of physicians and former patients started Planetree to do exactly that. At first, Planetree provided information at a time when patients were rarely told what was wrong or how it could be addressed. There was also a Planetree ward in a hospital in the Bay Area that operated on principles of transparency and person-centered care. Over the next several decades, Planetree developed as a network of more than 300 health care facilities in 30 countries that strive to provide a home-like environment for healing. The main value is person-centered care, in which they strive to treat the whole person as well as that individual's family or significant others. We invited Planetree President Michael Giuliano to tell us about it. He mentioned that one feature is getting your care summary in real time, so you can ask questions and correct errors before you leave the clinic or office. Fresh Air & Sunlight Built In One of the things that sets a Planetree hospital apart from other facilities is the way the values are visible in the architecture. Planetree planners put a premium on access to nature and outdoor space, though of course each facility does it a bit differently, according to its own plan. Rooms are set up so that people have access to fresh air & sunlight. That makes them feel more comfortable, certainly. Might it also promote healing? How Do Fresh Air & Sunlight Promote Healing? More than 150 years ago, Florence Nightingale set standards based on what she observed of soldiers healing from battle wounds and horrible infections during the Crimean War. This was, of course, before the development of antibiotics, so nursing care was paramount. Nurse Nightingale insisted on the primacy of fresh air & sunlight for her patients. Was this just a quaint old-fashioned idea, or is there modern scientific support? The Power of Near-Infrared For more information on the science of fresh air & sunlight (yes, there is science), we turn to Dr. Roger Seheult of MedCram.com. https://www.medcram.com/ He began by describing the brand new Footscray Hospital in West Melbourne. The design is something of a modern take on Florence Nightingale's hospital plan, since the architects figured out how to get natural light and real ventilation in every room. They prioritized fresh air & sunlight in this $1.5 billion hospital because of their healing properties. People exposed to sunlight leave the hospital sooner because they recover more quickly....

Millions of Americans are in pain. Arthritic joints make exercise difficult, even though moving is one of the best things we can do for joint pain. Pinched nerves can cause excruciating, long-lasting pain. The usual treatments, such as NSAIDs, may help ease the pain momentarily, but do nothing to help heal the underlying condition. What do you know about the new science of regenerative therapies? 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. The New Science of Regenerative Therapies What is the price of pain relief for aching, arthritic joints? We're not talking about the drugstore sticker on a bottle of ibuprofen. Instead, we are referring to the potential negative consequences of utilizing such medicines for temporary symptomatic relief when the joint continues to hurt for weeks, months or years. Even more powerful treatments, such as corticosteroid injections into the sore joint, don't heal the cartilage. In fact, they may contribute to further deterioration as they suppress the immune system. Our guest offers other ways to treat joint pain with regenerative therapies. Immune Mechanisms That Resolve Inflammation Dr. Tom Buchheit is a pain management specialist who has worked with elite athletes as well as seniors to get them moving well again after an injury. One of the reasons exercise can be so helpful is that the right kind and amount of movement creates good inflammation. Unlike chronic inflammation that causes further harm, good inflammation helps the immune system switch to a different phase, one in which destructive pathways are resolved. The three pillars of exercise are aerobic exercise, muscle building exercise and exercise to improve balance. Together, these types of exercise help recovery and healing and can even help heal damaged nerves. NSAIDs like naproxen, celecoxib or ibuprofen can interfere with the good inflammation exercise creates. Rather than taking such a pill before a game or workout, it makes sense to wait and take it afterwards if you need it. Will Exercise Wear Out Your Joints? Injury can damage the joints, but the idea of osteoarthritis as a consequence of wear and tear seems to be a medical myth. Instead, we might think of osteoarthritis as a chronic wound that may need regenerative therapies to heal properly. Immune system building blocks like omega-3 fats in the diet and a wide palette of colorful produce can help with the healing. Movement itself is part of the healing process. What Are the Regenerative Therapies? PRP Some of the therapies we think of as "new" have actually been in use for several decades. One of these is platelet-rich plasma, which was initially developed to help wounds heal. In this treatment, the doctor uses the patient's own blood. The plasma with as many platelets as possible concentrated in it is then carefully injected into the painful joint. The idea, again, is to cause "good inflammation," alerting the immune system that healing is needed here and encouraging it to flip into inflammation resolution mode. Not all studies of platelet-rich plasma (PRP) have shown benefit, but some of that may be due to using plasma that is not truly rich in platelets. Properly prepared PRP works especially well for ligaments and tendons, according to Dr. Buchheit. MSC If you hear someone talk of getting a "stem cell" injection, they are talking about MSC. They were originally misnamed mesenchymal stem cells, but would be better termed medicinal signaling cells. They too are derived from the patient's own body. Rather than rebuilding cartilage, they also signal the immune system...

This week, Joe and Terry discuss liver health with two specialists. You may not have spent much time thinking about your liver. It is, however, an absolutely essential organ. When the liver is working properly, every part of the body gets the nutrients it needs and no parts are exposed to damaging toxins. These are among its superpowers. Find out why you should love your liver. 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. Love Your Liver: Nutrients don't go directly from the intestines to the rest of the body. Instead, they pass through the liver first. There, this master organ breaks them down into compounds that can be recognized and utilized by individual tissues and cells. Moreover, if it finds nasty chemicals that shouldn't be there, it utilizes its superpowers to transform them into less damaging compounds that can be more readily excreted. You should also love your liver because it can store nutrients for unanticipated periods of fasting and hold off starvation. This was a tremendous benefit during earlier periods of human evolution. These days, we have less need for a hedge against starvation. In fact, when we overload our livers with alcohol or sugar, even its superpowers may not be adequate. The liver's response to this kind of insult is fibrosis, a condition in which it stiffens and stores fat. Liver Disease: One of the liver's superpowers is that it can regenerate itself so long as we remove the source of injury. That's pretty remarkable! But what if we keep on eating ultra-processed foods (Nutrients, May 10, 2023) and drinking soda or alcohol? In that case, the liver continues to try to repair itself. That can change the architecture of the tiny blood vessels that run through the liver, raising the pressure within them and ultimately leading to serious complications. Fatty liver disease, correctly termed metabolic-associated steatohepatitis (MASH), is the first step; cirrhosis and ultimately liver failure might follow. How Do You Know If Your Liver Is Healthy? The liver is so effective at maintaining the body in balance that most people don't develop symptoms of trouble until liver disease is quite advanced. As a result, the best way to keep tabs on liver health is through blood tests. Tests for the liver enzymes called ALT and AST are common and often used to assess liver health. Agents That Can Help or Harm the Liver: If you love your liver, consider drinking a cup or two of black coffee daily. This has been shown to help the liver fight inflammation and overcome early-stage liver fibrosis (Redox Biology, March 2025). Another precaution to take: avoid excess acetaminophen. This is the pain-relieving ingredient in Tylenol and hundreds of other over-the-counter medications. Doctors consider it safe for occasional use at doses under 4,000 mg in a day. Chronic use might call for lower doses yet. Because it is so widespread, people may mistakenly take several different medicines containing acetaminophen (paracetamol in the rest of the world) and end up exceeding the maximum dose by accident. Liver experts like our guest Dr. Ahmad treat such emergencies with a medicine called N-acetylcysteine. Other pain relievers, such as NSAIDs, are less likely than acetaminophen to damage the liver. Dangerous reactions to such drugs are unpredictable, however, which can make them harder to manage. Fluoroquinolone antibiotics such as Levaquin and corticosteroids like methylprednisolone also fall into this category. Oral antifungal drugs can also be very hard on the liver. Herbs That Can Challenge the...

A chance encounter with a stranger on an airplane offers lessons for all of us in how to disagree without fighting. Infectious disease expert Morgan Goheen, MD, was wary when the person in the seat next to hers struck up a conversation with questions about the origins of Lyme disease and the value of being vaccinated against COVID. His views were quite different from hers. Yet they managed, in the course of the flight, to exchange perspectives in a respectful manner. Can we all learn how to do that? 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 Disagree Without Fighting? Dr. Goheen did her best to answer the questions her seatmate had. She also listened carefully to his description of life during the pandemic, particularly his objections to mandatory vaccination and his fears of a reaction to the vaccine. As a health care provider, she had been working in a hospital that was overwhelmed with COVID-19 patients. Far too many of them died, and at the height of the pandemic, most died alone rather than with family nearby. She was able to recognize that this had colored her perception of the pandemic and had led her not to give enough attention to the real economic hardship some public health mandates triggered. The Value of Vaccines Before the polio vaccine was developed, parents lived in terror of polio epidemics that would tear through communities, leaving some children paralyzed and a few dead. We no longer have to fear polio, pertussis, diphtheria or measles because vaccines can protect children from these common diseases. In a sense, though, their very success has led to skepticism of their value. Most Americans do not know anyone who has died of pertussis (aka whooping cough) because the majority of children have been vaccinated against this pathogen. Recently, there have been few birth defects caused by rubella because pregnant women can be protected from the infection. Can Trust Be Regained? During the pandemic, opinions became polarized. People who would once have trusted the FDA or the CDC became suspicious. Public health messages about masking were initially based on conjecture, because no one had conducted actual studies until later in the pandemic. The nature of this new virus and its transmission was not yet well understood. Yet authorities occasionally made dogmatic pronouncements, possibly out of fear. Some opportunities to build trust were squandered, and it will take time and patience to get it back. Learning to disagree without fighting is a great place to start. Learning to Disagree Without Fighting After talking with Dr. Goheen, we turn to Dr. Laura Gilliom. She is a clinical psychologist active in the Braver Angels movement. This organization brings people together to bridge the partisan divide. The volunteers run workshops in which people with divergent viewpoints discuss issues of the day. They model basic approaches to good communication, including treating the other person in the conversation with respect. It is important to listen for understanding of the intellectual and emotional bases for their perspective. After all, people have reasons for their opinions. Even if you don't understand them, those reasons make a lot of sense to them and are usually the result of significant life experiences. When you speak, the aim is not to win the argument, but to be heard and understood. That is also the goal as you listen–to understand where the other person is coming from. When Braver Angels bring people together, all agree to state their views freely and without fear. That isn't always the case...

Chronic diseases make up the bulk of the problems that modern health care must address. Each condition seems to have its own drivers–cholesterol for heart disease, airway hyperreactivity for asthma, neurotransmitter imbalance for depression and other psychiatric disorders, a buildup of amyloid beta in the brain for Alzheimer disease. What if all these conditions had similar origins? Today we'll consider the evidence suggesting that hidden infections may be driving many chronic diseases. 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 Could Hidden Infections Be Driving Chronic Disease? Nikki's Story We begin this episode with the personal account of Nikki Schultek. She is a patient who has transformed herself into a research leader after a horrendous experience with unexplained chronic disease. She was a healthy active young mother whose lifelong well-controlled asthma suddenly took a dramatic turn for the worse. She then developed atypical pneumonia, heart arrhythmia and interstitial cystitis, along with a slew of autoimmune conditions. All the doctors could tell her was that these were idiopathic conditions driven by inflammation. As she notes, "idiopathic" basically is doctor-speak for we don't understand what is going on here. When she developed neurodegenerative symptoms that made her physician suspect MS, she was terrified. That low point became a turning point. Her background had equipped her to read scientific studies, so she began trying to figure out what was driving chronic disease in her own situation. A search linking atypical pneumonia and interstitial cystitis led her to the clinician who was able to help her regain her health, Dr. Charles Stratton. He had conducted a small study linking both conditions to a respiratory infection caused by Chlamydia pneumoniae. What Is When people hear "Chlamydia," they think immediately of the sexually transmitted infection caused by Chlamydia trachomatis. Although the organisms are related, they have completely different modes of transmission. People catch C. pneumoniae (Noo-mo-knee-eye) simply by breathing in air that contains infectious respiratory particles. These bacteria are extremely common, but it is difficult to detect an infection. That's because C. pneumoniae hides out inside human cells. It doesn't show up in blood tests or urine cultures. The study that caught Nikki's eye used PCR, polymerase chain reaction, which detects DNA. That analysis revealed that 80 percent of the women in the study with interstitial cystitis had C. pneumoniae. The researchers concluded that this sneaky pathogen can lead to chronic inflammation. The Link Between C. pneumoniae and Asthma Remember that Nikki's troubles started with a severe asthma exacerbation. Research has shown a link between that infection and hard-to-treat asthma (PLoS One, April 19, 2021). When Dr. Stratton tested Nikki, they discovered that she indeed harbored a C. pneumoniae infection. The treatment required multiple antibiotics over a prolonged period of time. Luckily, it eventually cleared the interstitial cystitis, the neurodegenerative symptoms, the other autoimmune problems and brought her asthma back under control. Other Pathogens Causing Trouble C. pneumoniae was not the only germ lurking in Nikki's body. She discovered that she also carried Borrelia burgdorferi, the organism that causes Lyme disease. In addition, an examination of her red blood cells revealed both Babesia and Bartonella, possibly transmitted by the same tick bite that gave her the Lyme disease. These experiences inspired...

Every five years, the Departments of Agriculture and of Health and Human Services jointly issue guidelines on what we should eat. The most recent Dietary Guidelines for Americans (2025-2030) have been controversial. [Here is a link: https://www.dietaryguidelines.gov] Among other things, the administration decided to flip the food pyramid upside-down in illustrating its recommendations. Why did that cause such a stir, and what will it mean for you? 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. Why Flip the Food Pyramid? Nobody has actually explained to us why they decided to flip the food pyramid on its head. The food pyramid itself debuted in 1991 as an illustration of what we should eat, but many people found it confusing. In 2011, it was replaced by a MyPlate graphic. So why return to the food pyramid now, especially upside-down? Our guest, noted nutrition researcher Christopher Gardner, suggest that it might be a way of denoting dramatic changes from previous guidance. Spoiler alert: only a few details are dramatically different. The main changes are a commendable emphasis on eating real food and attention to red meat as a protein source and full-fat rather than low-fat dairy products. Do Americans Need More Protein? If you pay attention at the supermarket, you'll probably notice that a lot of product tout their protein content. Even things that don't seem like they'd stand out as sources of protein (granola, pancake mix) are being offered in containers emblazoned with the promise of protein. Surprisingly, though, this is not a response to an urgent need. Most Americans get adequate protein and don't need to concentrate on increasing their intake. Might it be a marketing tool? Should We Worry About Dairy as We Flip the Food Pyramid? Generally, public health experts recommend that we avoid foods high in saturated fat such as butter or cheese and opt instead for lower fat items, like skim milk. Consuming excessive amounts of saturated fat can raise blood levels of dangerous LDL cholesterol. On the other hand, Dr. Gardner points out that dairy fat differs in some ways from the saturated fats in meat, for instance. We don't have enough studies to evaluate health consequences of consuming full-fat dairy. Will that raise cholesterol? Might it increase the chance of heart disease? We still need more research to be able to tell. What About Eggs? Speaking of cholesterol, what about eggs? For decades, Americans were warned not to eat eggs. Experts thought these cholesterol-rich foods would raise the level of cholesterol in our blood. But although eggs are high in cholesterol, they are low in saturated fat. Joe describes an astonishing experiment in which a person ate two dozen eggs a day. After a month, his LDL cholesterol was lower than when he started. Dr. Gardner remarks that we need to know not only what we are eating, but also instead of what and with what. Eggs with sausage and cheese are quite different from a veggie frittata. What's for Breakfast? Let's consider what people might be eating for breakfast instead of eggs. Quick toaster pastries, sweetened cereal, orange juice and toast with jam are all popular options that are high in refined carbohydrates. At least for some people, such foods may make blood sugar and insulin spike. That could lead to a midmorning crash, which in turn could encourage someone to have a midmorning snack. Is that a bad idea? Maybe it is one reason to flip the food pyramid. If We Flip the Food Pyramid, Will It Help with Weight Loss? Dr. Gardner has run studies comparing the...

According to the Alzheimer's Association, nearly seven million Americans currently suffer from that type of dementia. Experts expect that more will be burdened with it in the future, as baby boomers continue to reach advanced ages. Many people are eager to protect the brain from deterioration. In this episode, we discuss an unexpected approach to lowering your risk for Alzheimer disease (AD) and other dementias–get a shingles shot! 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 to Protect the Brain with Vaccination Our guest, Dr. Pascal Geldsetzer, has led three impressive studies that took advantage of natural experiments to see if vaccination against shingles could protect the brain from dementia. The results were remarkably consistent and encouraging. What Is a Natural Experiment? In Wales, when the Zostavax shot against shingles first became available, public health authorities established eligibility criteria to get it through the national health system. Welsh citizens had to be born on or after September 2, 1933, to get the shot. This created a situation in which two groups of people differed only by birth date and by whether or not they were immunized. (Most people who were eligible for the shot got it.) This mimics a randomized clinical trial in which the only difference between two groups is the intervention. The absolute risk reduction over 7 years was 3.5%, which means that people who got the shot were 20% less likely (relative risk) to be diagnosed with dementia. That big difference is statistically significant (Nature, April 2, 2025). Wales is not the only country that set up eligibility requirements. Australia did, too. In Australia, everyone between 70 and 79 years old as of Nov. 1, 2016, could get a free shingles shot and many people did. Here, too, you have a group of senior citizens who differ from each other only by whether they got vaccinated and whether their birthdays were slightly earlier or later. In this case, the absolute reduction in risk of dementia over 7 years was 1.8% (JAMA, April 23, 2025). This difference was also significant. One More Experiment Suggests Vaccination Can Protect the Brain Another natural experiment comes not from a nation, but from a province of our norther neighbor, Canada. The province of Ontario decided that people born on or after Jan. 1, 1946, could get a shingles vaccination. People just slightly older were not eligible. Do you recognize a pattern? When the investigators analyzed health records from 1990 to 2022, they found that people eligible for the vaccine based on their date of birth were 2% less likely to get a dementia diagnosis. In other provinces of Canada that had different rules for vaccination eligibility, people don't show a significant difference in dementia risk based on their birthday. (Lancet Neurology, Feb. 2026). Which Vaccine Were Scientists Studying? The original shingles vaccine, Zostavax, was the one available for all these natural experiments. For the most part it has now been replaced by a newer version called Shingrix, which uses different technology. Studies show that Shingrix is better at preventing shingles outbreaks and post-herpetic neuralgia, the lingering pain after shingles (Vaccines, April 28, 2025). It is unclear whether it would also work better to protect the brain from Alzheimer disease. At least one study suggests it works quite well in reducing the risk of dementia (Vaccine, Feb. 5, 2025). Was the Single-Minded Pursuit of Amyloid Misguided? For decades, the pharmaceutical industry has focused its...

Obesity is a big problem in the US. The National Institute of Diabetes and Digestive and Kidney Diseases says 2 out of every 5 American adults are obese. What's more, one in three is overweight, with only about 25 percent of us at a healthy weight. It's not just adults; children are increasingly suffering weight problems as well. In this episode, we ask why we eat too much and what we can do 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. Why We Eat Too Much: Excess weight puts people at risk for premature death from cardiovascular disease, kidney problems and diabetes. Unfortunately, the standard advice from physicians to eat less and exercise more hasn't often been very helpful. That's because it doesn't take into account the reason we eat too much: we are hungry. There are at least three different types of hunger that we need to consider, though. Most people are familiar with homeostatic hunger. If you haven't eaten for hours, your stomach may grumble and complain. There is also hedonic hunger–eating because something tastes delicious. That's why you can usually find room for dessert, regardless of how much dinner you've eaten. Hedonic hunger is often linked to emotional eating because you feel bored or stressed or depressed. The third type of hunger is conditioned hunger. Think of Pavlov's dogs, who learned to salivate in expectation of food when they heard a bell. Some people react much the same way when they hear a dinner bell, or when lunchtime arrives, or when they get in the car. If you are accustomed to eating then, you'll expect food and become disappointed if it isn't available. But conditioned hunger can be addressed by deliberately changing your patterns. Set up the environment so the food is not so readily available at the times you have become conditioned to eat. Hedonic hunger yields best to figuring out the emotional basis for why we eat too much: boredom, stress, some other feeling. What other activities can help you cope with those feelings? For some people, it might be going for a walk. Others might find a different approach more helpful. How Do Weight Loss Drugs Make Us Not Eat Too Much? The most popular drugs on social media and in ads lately are the GLP-1 receptor agonists. That's a fancy name for weight loss drugs like semaglutide (Wegovy) and tirzepatide (Zepbound). These medicines blunt the reward center in the brain that responds to food and drives some people to eat too much. They do that by mimicking satiety hormones, essentially telling our bodies "You've had enough." They work pretty well for most people, at least in the short term. However, unless people retrain themselves regarding eating cues (for conditioned hunger) or emotional needs (for hedonic hunger), they are likely to gain the weight back when they stop taking the medication. For homeostatic hunger, making sure to get adequate protein and fiber in every meal can help. That tactic might not be very useful for hedonic hunger, though. Are you addicted to ultra-processed foods? That can be a challenge. On the other hand, many people who are addicted to nicotine do find ways to overcome that addiction. It is possible to overcome junk food addiction, too. Dr. Fung describes his patient Harry who used fasting, eating carbohydrates last instead of first in the meal, along with some acid such as vinegar, and was successful in losing weight and feeling better. The most important thing Harry did was to use social support from his friends. Social and environmental factors are critical in the development of obesity, so...

Most medical interventions are either pharmacological–prescribe a drug–or surgical–remove or repair the offending body part. If those approaches are inappropriate, doctors long for a different technology. In this episode, we discuss the development of a relatively new noninvasive technology, focused ultrasound. Doctors use it to treat conditions such as Parkinson disease or essential tremor. It may also be used for tumors in other parts of the body. 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. Using Focused Ultrasound: Most people are familiar with ultrasound being used as a diagnostic tool. They also know about using a magnifying glass to focus a ray of sunlight. With the proper technique, this could light a small fire. In focused ultrasound, the surgeon uses an acoustic lens to target ultrasound waves very precisely inside the body. Dr. Neal Kassell, our guest expert in this episode, is a neurosurgeon. He has used focused ultrasound primarily to treat brain tumors. Treatments require from several hundred to several thousand ultrasound waves. But doctors have used focused ultrasound to treat over 180 medical conditions. Regulatory authorities around the world have approved its use to treat 35 different conditions. The first to get such approval was uterine fibroids. This technology has been used to offer noninvasive interventions for 22 years. Now, people with Parkinson disease could choose focused ultrasound as an alternative to deep brain stimulation. There are approximately 250 sites in the US that are able to offer this technology to patients. How Focused Ultrasound Works: Dr. Kassell described how ultrasound works for problems as dissimilar as liver tumors or essential tremor. There are multiple mechanisms, but scientists have concentrated on three: First, the beams of ultrasound generate heat that can destroy tissue where they are focused. So, tumor or tissue destruction is the first mode of action. Second, ultrasound involves the use of very tiny bubbles. These can be created to hold drugs. If a doctor were treating cancer, that might be a chemotherapeutic agent. But rather than exposing the entire body to the same level of medication, with focused ultrasound the microscopic bubbles trap the drug and release it only when exposed to the targeted beams. That means a high concentration of medicine where it is needed and very low concentrations elsewhere. Third, focused ultrasound appears to have an impact on the immune system. As a result, patients being treated with immunotherapy such as Keytruda get a much better result when it is combined with focused ultrasound. This approach has been shown to improve the response rate. Adopting Focused Ultrasound May Lag: Doctors and healthcare systems have customary patterns of practice, referral and reimbursement. Introducing focused ultrasound into the mix may disrupt these. Insurance companies might save money over the long run if they covered this long-lasting intervention. Perhaps they will find before long that they get a better outcome for a lower cost. Where focused ultrasound is finding more purchase is among veterinarians treating companion animals (dogs and cats) who also suffer from hard-to-treat malignancies. With the OneHealth approach, veterinary medicine shares what it learns from such treatments with healthcare providers treating humans. One might not imagine essential tremor as responding to this type of treatment, but 25,000 patients have already been cured. This entails separate treatments on two different sides of the brain, with the...

Medicine has changed enormously over the last several decades. As with other parts of society, digital technology has disrupted previous practices. Clinicians can now care for patients at home, monitoring them with sophisticated sensors for oxygen saturation, heart rhythm, blood pressure and much more. Even more significant, patients now have greater access to medical knowledge as well as to the state of their own bodies, measured through wearable tools such as smart watches or continuous glucose monitors. With the internet, they can connect with patient groups that offer valuable information as well as emotional support. Find out how patients are using technology to heal healthcare. 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 Technology Is Transforming Healthcare: When we spoke with Dr. Marschall Runge, we reminisced about the changes in medical care that have taken place since the time of his grandfather, a general practitioner. There is quite a contrast. While his grandfather made house calls, few doctors today would do so. However, some very modern medical centers now offer patients the option to recover at home from a major procedure. Dr. Runge describes his personal experience with at-home recovery following hip replacement surgery. The clinical staff was able to keep close tabs on his progress with the help of a variety of monitors, and a nurse was available to answer questions or provide advice until he was back on his feet. There are distinct advantages to the patient to be able to recover at home; among other things, he could sleep much better in his own bed. What other digital technology will healthcare employ? One possibility is using AI conversational agents to assist with differential diagnosis. Some devices can detect depression based on a patient's speech. Others can pick up heart rate variability, an important parameter of heart health. Dr. Runge does not expect that robots will replace doctors. They could be very helpful in certain situations, though. How Patients Are Using Technology: We turn next to Susannah Fox, author of Rebel Health. She has been studying how patients are using technology to improve their health for decades. We first met Susannah through our mutual friend, Dr. Tom Ferguson. He was a staunch advocate for self-care and excited about the prospects for the internet. (His white paper, "e-Patients: How they can help us heal health care" is a classic. Look for it at the website of the Society for Participatory Medicine.) Not only do patients everywhere now have access to PubMed (the National Library of Congress), they can also connect with each other. Peer-to-peer advice and care is a topic Susannah knows well. In some cases, patients have conducted research that is focused on the questions crucial to their lives; these are not always the same things that researchers want to study. One shining example of patient-initiated research is a paper in Nature on long COVID by the Patient-Led Research Collaborative (Nature Reviews Microbiology, April 17, 2023; initial publication Jan. 13, 2023). This paper has been downloaded 2 million times, illustrating the value of patient-led research. In addition to this outstanding example, some journals have adopted a policy of disclosing patient input into the research. Although very few studies report patient input, setting the expectation that they might make valuable contributions could help shape the perception of who ought to be involved in developing research protocols. Patients Using Technology to Access Medical...

In this episode, we interview the doctor who first identified seasonal affective disorder (back in 1984!) and went on to develop treatments. Even when days are short (but getting longer, little by little) and skies are gray, you don't have to suffer with a bleak outlook. Find out what you can do to counteract this common but serious problem. 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. One of the most effective treatments for SAD and the similar but less severe winter blues is bright light therapy. Not all sufferers respond to light therapy alone, however. Dr. Rosenthal describes the additional approaches that improve people's response. 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 November 13, 2023. What Is Seasonal Affective Disorder? By now, many people are aware that some individuals have a hard time with short days and long nights. Their appetites and sleep patterns may change, and they may retreat from social activities because they can't get energized. They have trouble concentrating and may become irritable. It's as if they get depressed every year at the same time, on cue. Psychiatrists estimate that about 5 percent of the population experiences seasonal affective disorder, or SAD. That could be as many as 10 million Americans. At times, physicians may prescribe antidepressants, but usually the treatment that works best for SAD is light. Evidence suggests that the lack of sunlight, especially when someone feels stressed, is a prime trigger for seasonal affective disorder. Is SAD Linked to Latitude? The further from the equator you get, the more pronounced are seasonal differences in daylight. Think of a place above the Arctic Circle, for example, like Tromsø, Norway. In the summertime, they celebrate the midnight sun. In the winter, however, people in Tromsø see very little daylight. Unless they are uncommonly resilient, they could be susceptible to SAD. Light for Seasonal Affective Disorder: The principal treatment for SAD is light therapy, usually utilizing a light box. This must be a minimum of one foot square and supply at least 10,000 lux. That is the equivalent of being outside on a cloudy day. Generally, the prescription is for 20 to 30 minutes of exposure every morning. People who would rather not use a light box might be able to spend that time outdoors under the dome of the sky. A roof, awning or umbrella would undermine the treatment. Approximately 30 to 40 percent of people with seasonal affective disorder do not respond completely to light therapy. They need additional help beyond light exposure alone. Exercise has been shown to benefit them, especially if it is conducted outside. Cognitive behavior therapy is also extremely helpful, as is meditation. Lastly, people with SAD may want to pull back from their usual social activities. If they can maintain their social connections, this is very therapeutic in the effort to defeat seasonal affective disorder. The Autumn Checklist for Defeating Seasonal Affective Disorder: Those who know that they often experience SAD should get ready before winter. Dr. Rosenthal recommends addressing the following questions: 1. Have I purchased a light box for the winter? 2. Do I have at least one bright, inviting room in my home? 3. Have I made plans for at least one winter vacation in the sun? 4. Should I check in with my doctor since I am entering my...

Inflammation is a double-edged sword. When you have a sudden injury or infection, your body responds by calling immune cells to the site of the problem. It may become red, swollen and painful, but all that is supposed to be part of the healing process. What happens with chronic inflammation is more insidious. Many serious diseases, such as diabetes, depression or heart disease, feed off chronic inflammation. Anti-inflammatory drugs can control the problem temporarily, but they have drawbacks if they must be used continuously. How can we go about calming chronic inflammation without medication? 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 Inflammation Works: One of the hallmarks of modern life is the impact of stress on the digestive tract. Excess weight, unrelenting stress and environmental toxins can all contribute to an immune system that goes into overdrive. Sometimes the consequence will be an imbalance in the microbiota, with the result that the tight junctions of the gut are disrupted. That can lead to "leaky gut," more respectably termed "intestinal permeability." When pathogens or toxins that should be confined to the gastrointestinal tract start circulating elsewhere, the immune system reacts. If the process continues, the consequence is chronic inflammation. Are there natural approaches to calming chronic inflammation? Calming Chronic Inflammation: When we want to help our immune system so that it doesn't have to be hypervigilant all the time, we should start with our diet. If dysbiosis contributes to leaky gut and inflammation, the best approach might be to feed our gut microbes what they need. In most cases, that means increasing our fiber. Gut microbes thrive on fiber, and most Americans don't get close to eating enough. Another important aspect, of course, is to avoid foods that might cause trouble. According to Dr. Low Dog, fructose degrades tight junctions in the intestines and could contribute to intestinal permeability and inflammation. To reduce fructose, we just need to cut back on sweets Finding Fiber in our Food: Where can we find fiber in our diet? Starting with breakfast, a lot of folks enjoy cold cereal, pancakes or pastries. There's not much fiber in any of those, unless you've chosen bran cereal. But even a choice as simple as eating an apple with the skin on can provide a good amount of fiber. Do you like salmon for breakfast? That's a very anti-inflammatory choice. One worrisome development is the spread of microplastics throughout our diet. As a result, most of us have microplastics in our bodies. Some of the compounds in these little particles of plastic are endocrine disruptors that contribute to inflammation. Maintaining Healthy Barriers: The colon is not the only part of the digestive tract that provides an important barrier. The mouth is also susceptible. Brushing, flossing, dental care and a low-sugar diet are important steps to protecting our bodies against chronic inflammation. Periodontal disease contributes in a major way. To maintain good tight junctions, we need to eat about 20 grams of insoluble fiber and 8 grams of soluble fiber daily. Beans and vegetables are great sources of both. Nuts and seeds like sunflower seeds or walnuts are also good sources. So are whole grains. And if we have any trouble reaching our fiber goals with diet, there is nothing wrong with adding a daily dose of psyllium, which is mostly soluble fiber. It lowers cholesterol and can reduce the risk of diabetes as well as promote regularity. Herbs to Ease Inflammation: In addition to...

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. 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. 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 fresh fruits and vegetables. Doctors Prescribing Produce: 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...

Millions of people are feeling apprehensive these days. The headlines are enough to make almost anyone feel anxious. People who are distressed may have a difficult time finding a therapist, however. There are too few, and consequently many are not taking new patients. Wait lists are long, often three to six months. Therapists who are accepting patients may not take insurance, and therapy can be pricey. A single session of gold-standard cognitive behavioral therapy can cost from $100 to $250. Could AI fill the therapy gap, offering psychotherapy online? 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 AI Fill the Therapy Gap? Conversational agents like ChatGPT, Gemini or Claude have become nearly ubiquitous. People use them to help write resumes, pitch stories, create images for web or social media posts and make financial projections. Using these chatbots to give feedback as in therapy is surprisingly popular. But how well can AI fill the therapy gap, really? Today's guest has been studying these interactions. Chatbots as Therapists: The conversational agents are also referred to as LLMs, for Large Language Models. It describes how they have been trained by scouring the internet. That allows them to predict the most likely word to come next in a sentence, or the probable next idea in a paragraph. They can't actually think, but if something has been posted online, they have access to it. At this point, the technology has become so refined that chatbots easily pass the Turing test; it is difficult to reliably distinguish AI from human responses. There are advantages to having "someone to talk to" any time, any place. Younger people in particular are digital natives and often feel more comfortable with technology than face-to-face with a human. What Are the Downsides of Having AI Fill the Therapy Gap? The training of AI agents as therapists, though, gives rise to some serious flaws. Because they are trained to elicit positive responses from humans to keep people engaged, they have a sycophancy bias. Have you noticed that most messages start by telling you your idea is great? That makes you feel good, and you are less likely to quit the conversation. But it isn't necessarily how therapy is supposed to work. If people are not challenged when appropriate, they may get stuck and not make any progress toward healthier attitudes or behaviors. They may fail to develop the critical skill of stress tolerance. In addition, chatbots are disconnected from reality. This could become a serious problem if a user starts to become delusional or is in an acute crisis. Anxiety as a Habit: Dr. Brewer suggests that we would do well to think of anxiety as a habit. He credits a 1985 paper by an investigator named Tom Borkovec suggesting that worry drives anxiety rather than being a mere symptom of anxiety. Worrying leads people to dwell on possible catastrophic outcomes, which understandably makes them more anxious. Treating anxiety as a habit, especially by finding a better reward than the illusion of control offered by worrying, could be effective. Responding with curiosity and kindness might offer a better outcome. He has studied this possibility. When you treat anxiety as a habit that can be changed, anxiety scores decline by 67%. That is quite impressive. Using Chatbots to Kick the Worry Habit Could Help AI Fill the Therapy Gap: One way to use AI effectively is to train conversational agents specifically to monitor for safety in other human-chatbot interactions. Given clear rules, they can do this very well. Also, chatbots...

Influenza usually starts in November, and cases increase throughout the winter, not fading until March or so. This year's flu season is especially severe. An awful lot of people are suffering with fever, cough, congestion, body aches, headaches and other symptoms of influenza. Of course, flu is not the only infection out there. Other viruses are also causing sniffles, coughs and pure misery. Is there any way to strengthen your immune system to be ready for cold and flu season? 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 to Strengthen Your Immune System: If you want to strengthen your immune system so it can fight off infections, the first rule is don't get in its way! In today's world, that is easier said than done. Drugstores are full of cold and flu remedies, and nearly all of those contain an ingredient designed to lower fevers. That is generally counterproductive. Fevers help the body in its battle against infection. In fact, you might want to induce a fever responsibly. Using Heat to Fight Flu: Numerous cultures have noted that people recover from respiratory infections like influenza more quickly if they are exposed to heat. They have developed myriad ways to accomplish this task. One that is accessible to most North Americans is hydrotherapy: application of heated, wet towels to the body for 20 minutes or so, followed by a brief exposure to cold such as a chilled-mitt rubdown. Take care not to burn the skin. Our guest, Dr. Roger Seheult, suggests that you can learn more about this approach from Bruce Thompson, an Australian physiotherapist whose website is https://www.traditionalhydrotherapy.com If hot wet towels do not appeal, getting into a sauna or even a hot tub for a short session might help. Pay attention to any contraindications, though. Above all, don't take medicines such as aspirin, ibuprofen, naproxen or acetaminophen. When they lower your fever, they are also reducing the effectiveness of interferon, which is one of the innate immune system's first lines of defense against viral infection. The widespread use of aspirin during the 1918 flu may have contributed to the horrifying death toll. Other Drugs That May Cause Trouble: Fever is not the only consideration. Many people now take powerful medicines to suppress their immune systems. These treatments alleviate the symptoms of autoimmune conditions such as Crohn's disease, ulcerative colitis, psoriasis, rheumatoid arthritis and eczema. Helpful as they are, though, they work in part by undermining the immune system. People on any of these meds are at higher risk for infection, and that is not good news during a bad flu season like this one. This might be a situation that calls for wearing an effective mask, such as an N95, when going out in public. Strengthen Your Immune System with NEWSTART: Paying attention to eight pillars of good health can help you strengthen your immune system. Dr. Seheult has offered a mnemonic he learned from a colleague, Dr. Neil Nedley of the Weimar Institute: NEWSTART. Let's find out what it stands for. Nutrition: Packing your diet with vegetables, fruits, whole grains and minimally processed proteins is smart prevention to strengthen your immune system any time of year. If you come down with the flu, you might want to consider chicken soup loaded with garlic. Garlic might be a good preventive measure also, while hot chicken soup can temporarily ease congestion and other symptoms. Nutritional supplements may also be worth consideration. Dr. Seheult cited a systematic review in the BMJ Global Health (Jan....

This week, we dig into the cooking oil controversy. For decades, we've heard that we should be using vegetable oils rather than butter, lard or other fats (possibly even olive oil). Oils from corn, soybeans, sunflower or safflower seeds are rich in polyunsaturated fatty acids. Consequently, people consuming them may have lower cholesterol levels than those primarily using saturated fats. But could there be a downside? We hear from scientists who have found these seed oils may be linked to certain cancers. The Cooking Oil Controversy: The more we learn about fats, the more it seems that focusing on just one aspect may be too simplistic. In the 1990s, health experts told Americans to avoid all fat. When it became clear that low-fat diets were not necessarily making everyone healthy, we got the message that we needed to stick with polyunsaturated fatty acids (PUFAs) like those in corn or canola oil. There are, however, different types of PUFA. Chemists classify them as omega-3, omega-6 and omega-9 fatty acids. Only omega-3 and omega-6 are considered essential fatty acids. Current cooking oils have a preponderance of omega-6 fatty acids. As a result, the ratio of omega-6 to omega-3 in our blood has risen from a pre-industrial average of an estimated 4:1 to our current ratios of 20:1 (Missouri Medicine, Sep-Oct. 2021). This could have biological consequences. Dietary Fat and Cancer: Dr. William Aronson has asked how different types of dietary fat affect the progression of prostate cancer. Laboratory studies show that a diet high in corn oil accelerates the growth of human prostate cancer tumors implanted under the skin of mice. That inspired him and his colleagues to conduct a randomized controlled trial (Journal of Clinical Oncology, Dec. 13, 2024). Fish Oil vs. Prostate Cancer: For their trial, they recruited 100 men diagnosed with prostate cancer who opted for active surveillance rather than immediate surgery or radiation. They assigned these volunteers to different diets for one year. One group followed their usual diet and did not take fish oil. The researchers instructed the other group in avoiding omega-6 fats in their diet, increasing the amount of omega-3 rich fish and taking fish oil supplements. Minimizing omega-6 fats meant staying away from fried foods, cooking oils, bottled salad dressing and mayonnaise. At the end of the year, there was a significant difference in an important prostate cancer biomarker called Ki-67. Does the Cooking Oil Controversy Extend to Other Cancers? We spoke with Dr. Timothy Yeatman about his research on colorectal tumors. His research was published in Gut, a leading journal for gastroenterologists (Dec. 20, 2024). He and his colleagues used a technique called lipidomics for their analysis. They found that the lipid profile of the tumors and their micro-environments is pro-inflammatory. They seem to lack the resolving mediators ("resolvins") that should normally accompany healing. The balance has been disrupted. Dr. Yeatman suspects that some of this disruption may be due to changes in the microbiome that constitutes a lot of the immediate environment for colorectal tumors. He suggests that extensive use of seed oils high in pro-inflammatory omega-6 fatty acids may contribute to the imbalance. You can find soybean oil, for example, in many foods where you might not expect it, such as breads, cakes, cookies, crackers, chips and even hummus. Cooking at home allows people to avoid seed oils, but it takes time, skills and resources that are not available to everyone. Can We Resolve the Cooking Oil Controversy? Neither of the studies we discuss during this episode is definitive. Scientists need more research to be able to make solidly evidence-based recommendations. However, both our guests would suggest we need not wait for the final word to reduce the inflammatory potential of our diets. Reading labels carefully is a good first step to avoiding...

This week, our guest discusses how to prevent and treat a surprisingly common condition, chronic kidney disease. One in three Americans faces the risk factors for kidney disease; one in seven is actually living with the condition, although they may not be aware of 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. Could Your Kidneys Be Failing? According to the CDC, 36 million American adults have some form of chronic kidney disease. There are six stages of this condition, with stages 1 and 2 so mild that they don't warrant treatment. Doctors start paying attention to stages 3a and 3b. Dr. Emily Chang describes how kidney disease is diagnosed and why we need to pay attention. In the earlier stages, kidney disease does not cause symptoms, so doctors rely on blood and urine tests to monitor function. What Do Your Kidneys Do? Most people are aware that the kidneys produce urine, primarily by filtering the blood and removing chemicals that are not needed. However, the kidneys also have numerous other functions that are critical for our health. They are vital to blood pressure control, and they regulate hormones essential to the preservation of bone strength. Main Risk Factors for Kidney Disease: We wondered why the rates of chronic kidney disease are increasing. The answer is fairly simple. More people have one or more of the factors that increase a person's probability of experiencing kidney problems. These include high blood pressure and diabetes. In addition, there are numerous medications that can contribute to trouble for your kidneys. Just imagine how many of us take an NSAID such as ibuprofen or naproxen multiple times a week. That can put a significant strain on the kidneys. If ibuprofen upsets your stomach–as it could–you might turn to a PPI such as omeprazole (Prilosec) or lansoprazole (Prevacid). These medications can also pose challenges for the kidneys. "Sick Day" Meds: In general, blood pressure medicines are a help to the kidneys, because blood pressure control is so important. But certain blood pressure meds, especially ACE inhibitors like lisinopril or ramipril or ARBs like losartan or irbesartan, are considered "sick day meds." They should not be taken on days when a person is under the weather and may be dehydrated. Under those circumstances, they might do as much harm as good. Another potential hazard for the kidneys is the contrast medium used in medical imaging. Sometimes this can be tough on the kidneys. That's especially true for cardiac catheterization where the doses are higher and the exposure longer. Staying Hydrated to Protect Your Kidneys: Besides controlling risk factors, we can all help protect our kidneys by making sure we stay hydrated. What and how much should you drink? Plain water is always great. Caffeinated soft drinks are not particularly helpful, and neither are dark sodas or tonic water. As for how much, that is individual. Most people can rely on thirst, but as we age, thirst may be a less sensitive indicator. Older people may need to make sure they are drinking enough fluid to produce a reasonable amount of light-colored urine. What Diet Is Best for Your Kidneys? According to Dr. Chang, most of us don't need to obsess about the amount of protein in our diets. Except at the most severe stages of chronic kidney disease, your kidneys can handle the protein you need for good nutrition. She recommends that people follow a DASH diet or a Mediterranean diet. Both are loaded with fresh produce, low in salt and sugar, and rich in whole grains. Scientists have studied the...

Do you know someone who has struggled for years to meet deadlines or manage their time? Perhaps you have a smart friend who just never did well in school (or possibly at work) because they couldn't seem to turn papers (or reports) in on time. Such people might find a diagnosis of attention deficit hyperactivity is a relief. Could it free them to find new and hopeful ways to cope with challenges? In this episode, we explore the transformative power of diagnosis. 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. The Transformative Power of Diagnosis: Our first interview on this topic is with psychiatrist Awais Aftab. Dr. Aftab has written about "the Rumpelstiltskin effect," so we asked him to explain it to us (BJPsych Bulletin, Aug. 22, 2025). He describes the relief and even therapeutic effect some people experience when their symptoms can be categorized by a diagnosis rather than as a character defect. This Rumpelstiltskin effect can be found in the folktales of a wide range of cultures as well as science fiction and fantasy. The idea that esoteric knowledge, even if it is only a name, can help offer a measure of control exemplifies the transformative power of diagnosis. The ritual of receiving a diagnosis may also give people relief from cognitive ambiguity. Some people find that a clinical diagnosis offers validation of their lived experience. In addition, getting a diagnosis may give them an avenue to connecting with others whose experience may be similar. Supportive communities have grown up around the diagnoses of autism spectrum disorder or Asberger's syndrome. Dr. Aftab views the transformative power of diagnosis alone, regardless of any treatment available, as similar to the power of placebo. Potential Downsides of a Diagnosis: Just as a placebo may relieve symptoms and also cause side effects, the transformative power of a diagnosis may sometimes work against a person. If the patient getting the diagnosis finds that it helps clarify new steps toward managing his or her discomfort, it is a benefit. But if instead it becomes an invitation to succumb to symptoms, then it could be harmful. Stepping into the sick role can become maladaptive. A Second View: We discussed this idea with another psychiatrist, Dr. Robert Waldinger. He pointed out that a person's previous experience and their family's expectations could have a significant impact on whether the transformative power of diagnosis works for good or for ill. One example might be hypertension. One person receiving that diagnosis might remember that his father had hypertension and took his blood pressure medicine conscientiously and lived to a ripe old age. Another person might get the same diagnosis and freak out because a grandfather with hypertension died of a stroke. Helping People Manage without a Diagnosis: When life is hard, people may become anxious or despondent without a clinical mental disorder. They still need support. How can we help people talk about their uncomfortable feelings? Even mental health professionals may need practice to feel comfortable actually talking about a person's authentic feelings. They may be frightened that the person will reveal despair that they don't know how to alleviate. Dr. Waldinger reminds us that we don't have to fix another person's feelings, but truly listening can itself help. Authentic communication is the heart of connection. As with the transformative power of diagnosis, simply being heard and acknowledged may make a person feel better. Dr. Waldinger is fond of this quote: "Attention is the most basic form of love." Relationships can...

When doctors talk about infections, they are usually referring to acute situations in which the immune system gets overwhelmed by a virus such as influenza or chickenpox. Infections also result from the interaction of bacteria with the immune system, as in the case of pneumonia or sepsis. These can be crises, but they are relatively short-lived, resolving one way or the other within a few weeks or at most months. Could infections trigger chronic diseases? Our guest, evolutionary biologist Dr. Paul Ewald, thinks they do. 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 Infections Trigger Chronic Diseases: Investigating the origins of chronic diseases requires a great deal of patience and the ability to examine several different areas that might be relevant. Over the past few decades, the technology for evaluating genetic contributions has improved greatly. What we have learned is that most chronic conditions are associated with a range of genes that each add a small amount of risk. To get further insight, we have to look at the environment. This broad area includes topics as far ranging as sunshine, stress and nutrition. In particular, we need to look at the pathogens present in any given environment, as they could play an important role in our health. Scrutinizing the environment is not enough. To understand the impact on disease, we need to know more about human behavior within that environment. How much sun exposure do the patients get? Are they sleeping? Where do they spend most of their time, and with whom? These all will help us understand the link to pathogens. What We Have Learned About the Microbiome: Over the past several decades, scientists have learned a great deal about the microbiome. The original conception of gut bacteria has been enriched with the understanding that almost every part of the human body has its own microbiome, almost as unique as a fingerprint. These collections of microbes live in harmony–or disequilibrium–with microbes from the environment. Some of these may be beneficial. Others undoubtedly are harmful, and we call them pathogens. How do pathogens trigger chronic diseases? How Does the Body React to Pathogens? When pathogens are detected, the immune system responds. Often, that comes in the form of macrophages, immune cells that circulate in the blood and attack the pathogens. Even a type of microbe that normally cohabits peacefully with the others in its space can cause trouble if it becomes too numerous or goes out of bounds. One example is Porphyromonas gingivalis. It's usually found in the mouth. If it gets too exuberant there, it can cause gum disease. Worse, though, the macrophages dispatched to deal with P. ginigivalis anywhere in the body can end up collecting in atherosclerotic plaque in arteries (Signal Transduction and Targeted Therapy, May 23, 2025). Another example of pathogens causing unexpected trouble is Clostridium (or Clostridioides) difficile (C. diff). These bacteria can live among other gut microbes and you might not even know they were there. But if the microbiota become disturbed, from a course of antibiotic treatment, for example, C. diff can proliferate and cause terrible diarrhea that may be very difficult to treat. Studies indicate that C. diff has evolved so that the strains in hospitals are now more likely to be resistant to antibiotic medications. Alzheimer disease seems like a chronic condition rather than a complication of infection. Certainly, researchers have been examining genetic predispositions for the accumulation of beta-amyloid...
