Health Discovered

In last week’s episode, we learned how ultra-processed foods hijack our brains, leaving us with addictive food cravings that don’t always serve us. How can we cut down on our consumption of ultra-processed foods without being overly hard on ourselves or too restrictive? In this two-part series, Barry Smith, PhD, sensory expert, founding director of the Center for the Study of Senses, and a scientist that has worked with food companies and learned how they hijack our food cravings, returned to speak with us about what we should really be looking for on ingredient labels to make better choices and tips for hijacking our brains back to help us reduce our cravings of ultra-processed foods, through strategies like slowing down with mindful eating and bringing back communal meal times.

Have you ever wondered why the foods you crave don’t always leave you feeling your best after eating them? What if you knew these foods are designed to be addictive and play with our dopamine levels? This is what happens in ultra-processed foods. But what do we mean when we say ultra-processed food? How do they impact our health and how we experience eating? In this two-part series, we speak with Barry Smith, PhD, sensory expert, founding director of the Center for the Study of Senses, and a scientist that has worked with food companies and learned how hard they work to hijack our food cravings, about what defines ultra-processed foods, how companies work to make these foods addictive, and what exactly is happening in our brains to crave these unhealthy foods.

Respiratory Syncytial Virus (RSV) is often thought of as a childhood illness, but it poses a significant threat to older adults as well. According to the CDC, RSV infected approximately 65 million people globally last year, leading to an estimated 160,000 hospitalizations among adults aged 60 and older. What does RSV look like in adults, and what symptoms should you be vigilant about? In this episode, we are joined by Dr. Kizzmekia Corbett-Helaire, a renowned vaccinologist and assistant professor at Harvard T.H. Chan School of Public Health, who breaks down the risks, ongoing vaccine development, and prevention strategies for vulnerable populations, particularly older adults. We also hear from Irene, who, at 69-years of age, experienced severe, unfamiliar, cold-like symptoms that ultimately led to an unexpected RSV diagnosis.  This podcast episode was recorded on September 4th, 2024.

When we think of medicine, we usually picture pills, injections, or other treatments, but what if the most powerful medicine was on our plate? How can the right diet truly transform our health? We spoke with Dariush Mozaffarian, MD, PhD, cardiologist, and Director of the Food is Medicine Institute at Tufts University, about what defines a healthy diet, integrating food into healthcare, and how important policy changes are needed to prioritize food and nutrition in addressing public health.

When you hear "hospice" or "palliative care," what comes to mind? How do these services focus on enhancing quality of life? And when is the right time to research and engage them for our loved ones? In this episode, we break down the myths and realities of hospice and palliative care. We spoke with Neha Shah, MD, infectious disease and palliative care doctor, about the collaborative nature of palliative care teams, the essential role of caregivers, and what really happens in end-of-life care in a discussion to empower you with knowledge and compassion for whatever lies ahead.

Most of us are aware of the risks of air pollution, but what about the pollutants we encounter inside our homes every day? In 2024, the American Lung Association reported that over 131 million people in the U.S. are exposed to unhealthy levels of pollution, but the dangers don’t stop at the front door. In this episode, we dive deep into the topic of pollution with Philip J. Landrigan, MD, MSc, FAAP, a leading expert in global public health. Dr. Landrigan helps us identify different sources of pollution, including microplastics, pesticides, and air pollution, and their health risks. Learn practical strategies for minimizing exposure, safer alternatives to common pollutants, and how pollution is linked to climate change.

In 2023, the opioid crisis claimed over 81,000 lives -- a staggering number, yet many of these deaths could have been prevented. While prescription opioids can be essential for managing pain, they come with significant risks that are often overlooked. In this episode, we dive deep into the hidden dangers of opioid prescriptions and explore the crucial questions you should ask before accepting these medications. Ellen Eaton, MD, a leading expert in opioid treatment from the University of Alabama Birmingham, joins us to discuss the real risks of misuse, the warning signs to watch for, and the steps you can take to protect yourself and your loved ones. From understanding the potential side effects, to navigating the road to recovery, this conversation sheds light on the opioid epidemic and the urgent need for prevention and education. UAB Medicine Addiction Recovery Services Transcript Neha Pathak, MD, FACP, DipABLM: Welcome to the WebMD Health Discovered Podcast. I'm Dr Neha Pathak, WebMD's, Chief Physician Editor for Health and Lifestyle Medicine. Many of us have talked to our children and loved ones about how to respond if they're offered an opioid or some other unknown substance, even if it's candy at a party, fearing the dangers of opioids and overdose. But how many of us think about the risks in these situations? Our child is injured playing sports and we're given a 14-day prescription for an opioid containing medication. We're at the dentist's office and we're given a prescription for an opioid for a short course after a procedure. New data shows that there were over 81,000 opioid deaths in 2023. So, what can we do to keep our loved ones safe? Today we'll talk about the best strategies to prevent opioid misuse and abuse in the first place. Even if it starts with a prescription from our doctor's office. The journey to addiction and to recovery and what we need to know about preventing opioid deaths.   But first, let me introduce my guest, Dr Ellen Eaton. Dr Eaton is an associate professor at the Department of Medicine at the University of Alabama at Birmingham. She's the director of the office based opioid treatment clinic at the UAB 1917 clinic, and a member of the leadership team of the UAB Center for Addiction and Pain Prevention and Intervention. Welcome to the WebMD Health Discovered podcast, Dr Eaton. Ellen Eaton, MD: Thank you so much for having me. Pathak: I'd love to just start by asking you about your own personal health discovery. So, what was your aha moment that led you to the work that you're doing with opioid treatment, management, and addiction and pain prevention interventions? Eaton: Yeah, I have an interesting story as an infectious diseases physician who is primarily working on substance use treatment and prevention. I had the honor of being a fellow with the National Academy of Medicine, really a health policy fellowship. And as an infectious disease physician, I was invited to a working group around infectious consequences of the opioid epidemic. And that was in 2017. It was a tremendous opportunity to go to D.C. and work with thought leaders in the field, other physician scientists, infectious diseases doctors, and those experiences and treatment models that I was hearing about in D.C. were not happening in my home institution at UAB. There were addiction medicine physicians, but we hadn't integrated care. We were not doing syndemic care where you're treating the infection, preventing Hep C, and you're treating their substance use disorder. So that opportunity in 2017 inspired me to come home to UAB, create a clinic here that is for our patients living with HIV who have opioid use disorder, and from there, we've really expanded services broadly for substance use and infectious diseases. So really grateful for the National Academy and that opportunity. That really was a launch pad for my career. Pathak: I would love to talk about what you've seen as the entry point for a lot of people when it comes to opioids and that progression to addiction, potentially overdose. What does that look like for many of the people that you see? Eaton: Because of the care I provide, I am seeing patients who are living with substance use disorder, but I always start when I meet them with really open-ended questions like tell me about your first exposure to opioids. Tell me when you began using them for medical reasons or recreationally. And what I hear over and over again is that many of our patients are starting to experiment or use from a prescriber for a medical condition in their teens or early twenties. And that is often a trusted medical provider. It may be an urgent care physician for a musculoskeletal injury, for a teenager on the athletic field who was injured. It may be a woman who just delivered a baby, a very healthy, common touch point, where there may have been a tear or maybe some residual pain.   Another common touch point is a dentist treating you for a dental infection. And so, I hear these types of anecdotes over and over from my patients, and often it is a trusted physician, so they don't feel like this is a scary medication. They may be given a 14-day supply of opioids, not realizing that can lead to physical dependency and opioid misuse in the future. And often don't ask questions about what to look for, warning signs, and certainly as young people, I haven't ever heard that their caregiver expressed concerns. I think more often the patient has a prolonged course seeking opioids for various conditions, becomes dependent, is seeking them more and more, and often caregivers or family members don't get involved until they are pretty far down the continuum of opioid use disorder. So, those are the stories I hear when I meet patients and ask about their journey. Pathak: What are some of the questions we should ask before we even accept that prescription? Eaton: This is a really important question at that prevention touch point, that we often miss. I think asking your provider do you really need oxycodone. Could you start with something like an NSAID or a Tylenol. Asking your provider to be very explicit. When my pain hits a seven out of 10, when my pain hits an eight or nine out of 10, when do I need to take this opioid as opposed to some other opioids sparing pain modulators? And then number of days. So not just at what point today, but also tomorrow, the next day, what pain should I expect, and I think setting the expectation you will have some pain. This is a challenge that many of us that see patients in a primary care setting have to remind patients, you will have some pain. That is normal. That is healthy. That means your nerves are telling you they're giving you feedback on what's going on after your leg fracture. And I think unfortunately opioids have been normalized as safe, in many cases they can be, but in many cases they are not.   I also see amongst families where an individual will tell me, “Oh, well, I got a Tramadol from grandma, or I had some opioids leftover from that time that I had a surgery and so I took that for some other condition,” comparing them to medications like chemotherapy, which also have risks. You would never hear a patient self-medicating, sharing with friends and loved ones. But I think because opioids became so ubiquitous, in past decades, entire families, kind of normalize them. They feel comfortable sharing them, taking others. And that type of culture leads to a culture where young people feel comfortable experimenting. They take pills at parties, they take pills from friends and, they purchase them off social media, like TikTok for example, because they do not appreciate the adverse outcomes that can be associated with these types of medications. Pathak: So, tell us about this slippery slope. What is it that happens to us when we take these medications unnecessarily? Eaton: Often one of the biggest teaching points that I make with trainees in my clinic, when is someone experimenting and when does it become a use disorder? And in my clinic, it's usually pretty clear and that includes negative consequences. So, taking opioids and falling asleep, nodding out, overdosing, right? Those patients have gone from opioid misuse to use disorder. So having negative consequences, becoming physically dependent. We do see that needing to take more and more to prevent withdrawals, which with opioids, unlike some other substances, you can pretty quickly become physically dependent. And then you need to continue to opioids just to not feel sick, to not have the flu-like symptoms. So, becoming physically dependent, having to take more and more, increasing your dose to get the same desired effect. Those are the things that I see most commonly in clinic. With opioids and certainly the very potent non-medical opioids we're seeing now, heroin, fentanyl, we don't see people who just dabble here and there at a party, at a wedding.   Now the other substances that I see pretty routinely used in my clinic with or without opioid use disorder, stimulant use disorder, marijuana use disorder. Alcohol use. I do have to ask more questions and certainly there are validated screening tools out there that physicians and clinicians can use to determine very objectively. Did they just drink too much at that wedding two months ago and it was a problem because they got in a fight or had a DUI? Or is this a pattern of use that meets criteria for alcohol use disorder?   So, it is important to ask those questions and know, but I would say really the negative consequences, the physical dependency, escalating use, those are things to look for in your patients. As a caregiver or a parent, those are things to look for as well because we are really in a position to identify these before our loved ones have escalated their use. Pathak: And then what do you do? So, you notice some of these types of red flags. What is the intervention that you should make as a parent or a loved one or a caregiver?

As we spend more time outside, it’s important to remember to protect our skin from the sun’s rays. While we know sunscreen is needed, it’s also important to know how to select the right sunscreen. Which chemicals in sunscreens should we avoid? How are manufacturers ensuring their products are safe and effective? And what ingredients provide the best protection against overexposure to the sun? We spoke to David Andrews, PhD, deputy director of investigations and a senior scientist at Environmental Working Group (EWG), about what to look for when buying a protective sunscreen, how to minimize our risk to harmful exposures, a step-by-step approach to protecting our skin, and EWG’s handy sunscreen guide. Transcript Neha Pathak, MD, FACP, DipABLM: Welcome to the WebMD Health Discovered Podcast. I'm Dr Neha Pathak, WebMD's Chief Physician Editor for Health and Lifestyle Medicine. Even though we usually associate summertime with sunscreen, the truth is we need sun protection all year long. In today's episode, we're going to focus on all things sunscreen and sun protection. What are the safest steps to protecting ourselves and our skin? How do we make sense of all the labels, SPF, broad spectrum, UVA, UVB, chemical, mineral, and how can we be sure that we're using the safest and most effective products?   To guide us through this topic is our guest, Dr David Andrews. Dr Andrews is Deputy Director of Investigations and a Senior Scientist at Environmental Working Group. His work focuses on finding ways to protect public health by educating consumers and driving change to government policies and regulations. Dr Andrews has been researching sunscreens for more than 15 years and has published a peer reviewed study on sunscreens with EWG colleagues and a book chapter with researchers in Australia. Welcome to the WebMD Health Discovered podcast, Dr Andrews.   David Andrews, PhD: It’s a pleasure to speak with you today. Pathak: Before we jump into our conversation, I'd love to ask about your own personal health discovery, your aha moment around the work that you do specifically around sunscreens.   Andrews: I've actually been at EWG for just over 15 years now. My oldest just turned 16. So, I also have a few kids and know their response to sunscreen, some positive and some negative. What stood out to me was when I started researching the efficacy of sunscreens. In particular, I'm coming at sunscreen and sunscreen use from the perspective of really long term skin damage and increased skin cancer risk. What really stood out is kind of the lack of scientific knowledge still on what exactly causes in particular increased melanoma risk, and that linkage to sunscreens and some of the uncertainty that has enabled what is somewhat subpar sunscreens in terms of providing UVA protection. So providing protection from a portion of the spectrum.   Part of that is really a reflection of how sunscreen use has changed incredibly over the decades and the initial products were really just to prevent sunburn. In my family growing up we referred to them as sunburn creams. But it was really that change in use and kind of the lack of really strong protection in the UVA region that stood out to me. One piece that really stood out is when the FDA published what was more or less their more recent change to sunscreen regulations in 2011. They discussed how sunscreen use was associated with reduced risk of skin damage and skin harm when you use the products because it reduced the amount of UV rays that hit your skin. But the FDA also noted that the few studies that had looked at sunscreen users found that they actually changed their behavior and spent more time in the sun and were actually getting slightly increased sun damage. There's this juxtaposition of we know UV rays and sun rays can cause skin harm and sunscreens reduce the amount of those UV rays. But if we're using sunscreen and changing our behavior, then we may actually be negating some of the benefits of sunscreen. Those complex science issues have really drawn me into this issue and have kept me kind of focused on trying to understand this and provide guidance to the public for the last 15 years. Pathak: That's so interesting. Let's start with some definitions of some common terms. We all think of sunscreen as helping to protect us from damaging rays from the sun. Help us break down those components of solar radiation that we're talking about UVA, UVB, visible light, and infrared. Help us think about those different types of solar radiation that we're trying to protect ourselves from. Andrews: It does get very complicated with the terms. The UV radiation or ultraviolet radiation is sun radiation we cannot see. The radiation is broken into two parts, typically, UVB and UVA, at least in the context of sunscreens. Those UVB rays are the rays most associated with acute damage that's turning your skin red and sunburns. UVB rays are also associated with increased skin cancer risk. But UVA rays are also associated with increased cancer risk as well as skin aging, long term skin damage and impacts on the skin immune system. So the ability to heal from sun damage. But the original sunscreens primarily just block the rays that cause sunburn and actually led to increased UVA radiation. So it's those two portions of the spectrum that I often refer to. UVB is the portion that causes direct skin damage. You see the impact right away or within 24 hours. The UVA rays penetrate deeper into the skin and are associated with long term skin harm. Pathak: Tell us about SPF and broad spectrum and some of these terms that we see on the sunscreens that we're buying. What are these different components? What are we supposed to be looking for when we're looking for a good protective sunscreen? Andrews: I think of a good sunscreen or the ideal sunscreen as something similar to a shirt. A shirt actually provides perfect uniform protection against UVA, UVB rays, and even blocks visible light. People can't see you through your shirt typically, and so that is kind of the ideal. The SPF value in sunscreens is representative of the sun protection value. It comes from a measure of skin redness.   The way sunscreens are tested, they apply small amounts on people's back, expose them to high intensity radiation for a short period of time, equivalent to, solar exposure, much stronger than the sun, and then look a day later and see how read the skin turned. That SPF number is the direct reflection on primarily UVB protection. The UVA protection or the broad spectrum protection is not incorporated into that SPF or UVB value, although there are some standards in the United States for how much UVA protection is required. The issue is those standards in the United States are very low. They actually lag the rest of the world. In part, that is due to the ingredients available to sunscreen manufacturers in the United States. The underlying concern here is that people are being overexposed to UVA radiation, which is leading to long term skin damage and skin harm. Pathak: Can we have it all? Do we have products available to us in the United States that provide strong protection and also minimize the risk from certain chemical exposure. Is that a unicorn or can we find that on our shelves in the US? Andrews: There are good options available. That is an important takeaway. Primarily these are products that are using zinc oxide. These are mineral based sunscreens. Sometimes they can be a little bit whitening, although formulations have improved significantly over the last decade. These zinc oxide mineral based sunscreens do a very good job of providing UVA and UVB protection, They do so without the use of concerning ingredients. There is a space there, and there's definitely options available to consumers, and we have typically directed people to first try those products and potentially you need to try a few different products to find one that works for you. But these zinc oxide based products are the best available option on the market currently Pathak: What are some of the things we're looking out for if you have skin of color?   Andrews: That's a really interesting question. I think it reflects a deficiency in both that SPF value and the current structure in the regulations from the FDA on how sunscreens are tested, and how the effectiveness is communicated. Primarily, these are products tested on very light skin types, that are looking for that skin redness. I don't have a direct answer to that question of if there is no skin redness, how can you be sure that you're protecting the skin because of that lack of direct feedback other than the advice of if you're going out in the sun, especially for prolonged periods, consider covering up using a sunscreen or seeking shade. I think it's important to come back to that, though, that in the context of sun damage, and sunscreens, the sunscreens alone are not the complete solution here. It is a mixture of wearing a shirt, covering up, seeking shade, and using sunscreens to reduce that overall exposure. Pathak: I definitely want to talk a little bit more in depth around your step by step approach to thinking about all of the different tools we have in our arsenal to protect us from solar radiation. But I wanted to go back to an earlier point you made around some safer ingredients that you're looking for such as looking for zinc oxide. What is the converse of that? What are some of the ingredients that you would really recommend people stay away from?   Andrews: I should note that the FDA proposed changes to sunscreen regulations four or five years ago now that have not been finalized. They highlighted that all of the non mineral ingredients, these are oxybenzone, avobenzone, a large portion of the sunscreen market in the US. The active ingredients were absorbing into the skin at levels where they were being systemically distributed throughout the body and the FDA was looking for more safety data

When we think of receiving health care, often what comes to mind may be sitting in an exam room, being in a hospital, or visiting a pharmacy. But what about when we receive healthcare virtually? How do telehealth appointments, wearable devices, and health apps impact our access to care and shift how healthcare is provided in this day and age? In this episode, we spoke to Aditi U. Joshi, MD, digital health strategist and emergency medicine physician, and João Bocas, CEO at Digital Salutem, about emerging healthcare tech, how technology can bridge the gap between advancement in healthcare and human connection, and what people can do with healthcare tech to dramatically improve their health. Additionally, we sat down with Jason Saucier to hear his powerful story on how his Apple Watch discovered his atrial fibrillation and how he was positively impacted by his wearable device.

In today's dating culture, we often hear the word "ghosting" thrown into the mix. Ghosting, the practice of ending a relationship abruptly, usually leaves us feeling lost, anxious, and confused. Why does ghosting happen? Do we really need closure? How can those struggling with goodbyes learn the tools for a healthy goodbye? And what are some ways we can manage our emotions during a breakup or significant life change? We spoke with Lia Love Avellino, licensed clinical social worker, modern love therapist, and founder of Spoke Circles, a group support hub, about the practice of "good goodbyes" and "power parting," healthy ways we can confront difficult emotions whether we're the recipient or the initiator of an ending, and advice for those currently struggling with a goodbye.

It’s no secret that working on our physical, mental, and emotional health can drastically change the quality of our lives. But how exactly can working on your emotional health with a supportive community be a transformative experience? And how can working on your physical health improve your self-esteem, relationships, and professional life? We spoke with Nate Checketts, Co-Founder & CEO of Rhone, a premium performance lifestyle company, about the importance of developing a mental health toolkit, the benefits of practicing gratitude, overcoming resistance to change, and his 12 pursuits initiative rolling out this year.  

In 2023, there were over 56,000 wildfires in the United States, which burned over 2.6 million acres. While we may be familiar with the environmental and structural effects of wildfires, the health impacts of climate change are wide-ranging. From extreme heat to massive wildfires resulting in long range plumes of wildfire smoke, what are the acute and chronic health issues we may experience? How does heat play a role in the worsening of wildfires? And how do these exposures impact the largest organ in our body: our skin? We spoke with Daniel Swain, PhD, a climate scientist at the Institute of the Environment and Sustainability at UCLA, about the causes of wildfires and the role extreme heat plays. We then sat down with Shadi Kourosh, MD, MPH, dermatologist and Associate Professor of Dermatology at Harvard Medical School, about important measures for protecting our skin’s health in the face of wildfires.

About 53 million U.S. adults are diagnosed with arthritis. How is arthritis diagnosed? Why and when does it usually arise? And what are the options available? We spoke with Robert McLean, MD, rheumatologist and member of the clinical faculty of the Yale School of Medicine, about the common types and symptoms of arthritis, from rheumatoid to psoriatic, various treatment options available, and the recommended lifestyle interventions to ease arthritis pain.
