    Is Your Grass Fed Beef Actually More Nutritious? with Dr. Lucas Krusinski

    IN THIS EPISODE Is grass fed beef really worth the extra money? And how do you know you're getting what you pay for? In this episode of the ReThink Health Podcast, I sit down with Dr. Lucas Krusinski, an assistant professor of animal science whose research looks at how farming practices change the nutrients in our food. I read many of his papers while preparing for my own dissertation on beef nutrient density, so this conversation has been a long time coming. Dr. Krusinski explains why not all beef is created equal. He walks us through how a cow's diet, pasture diversity, and feed supplements can change the omega-3s and plant compounds that end up on your plate. He also shares findings from his newly published paper on a surprising gap in the food system: many labels promise better nutrition, but almost none actually test for it. He even shares early results from a study in which he tested 40 brands of beef liver supplements. What he found may change how you shop for them. You'll learn: Why "grass fed" and "pasture-raised" labels may not tell you as much as you think The one nutrient Dr. Krusinski would use to judge the quality of beef, and why How a national survey found huge differences in the omega-3 content of beef that was all labeled "grass-finished" The levers ranchers can pull to raise omega-3s in beef, including pasture diversity, hay, fermented forage, and flaxseed What testing 40 beef liver supplements revealed about vitamin A, minerals, and quality How eggs, chicken, and pork compare to beef when animals are raised on pasture How Dr. Krusinski shops for beef, including the visual clues he trusts more than labels Whether you're a conscious meat shopper or a rancher who wants to raise more nutritious food, this episode will help you look past the label to make more informed decisions.

    Is Cancer Actually a Metabolic Disease with Dr. Thomas Seyfried

    IN THIS EPISODE What if we've been looking at cancer the wrong way for more than 70 years? In this episode of the ReThink Health Podcast, I sit down with Dr. Thomas Seyfried, a professor of biology at Boston College and author of Cancer as a Metabolic Disease. For decades he has asked a question most of oncology stopped asking long ago: what if cancer isn't driven mainly by bad genes? This conversation is deeply personal for me. My dad battled cancer three times, and I recently lost him. Two of my close friends, one in her 40s and one in his 50s, are facing cancer right now. Dr. Seyfried's work was a source of hope for our family, and I know cancer touches almost everyone's life. Dr. Seyfried explains why he believes cancer is primarily a mitochondrial metabolic disease. His argument builds on the work of Nobel laureate Otto Warburg and on his own lab's research into how cancer cells rely on two fuels: glucose and glutamine. He walks us through the nuclear transfer experiments that challenged the gene-centered view of cancer. He also explains why cancer cells "ferment" for energy instead of "breathing" like healthy cells. You'll learn: Why Dr. Seyfried believes the gene mutations found in cancer are an effect of the disease rather than its cause The difference between fermentation and respiration, and why cancer cells keep fermenting even when oxygen is present Why he says glucose and glutamine must be targeted together, and how his "press-pulse" strategy works How to use the Glucose-Ketone Index to see where your metabolism stands Why ketones are often called a "super fuel" for healthy cells How alcohol, portion size, exercise, stress, and fasting affect your glucose ketone index (GKI) What forever chemicals and rising childhood obesity may mean for cancer rates in kids What a day of eating and living looks like for a researcher who has studied cancer for 40 years If you or someone you love has been touched by cancer, this episode offers a different perspective and practical tools to bring to your conversations with your healthcare team.

    The Glycine Masterclass, with Dr. Joel Brind

    IN THIS EPISODE What if the most overlooked nutrient in your diet isn't a vitamin or a mineral, but a simple amino acid your body already makes? In this episode of the ReThink Health Podcast, I sit down with Dr. Joel Brind, a biochemist with over 50 years in medical research and the author of The Glycine Miracle. Dr. Brind has spent nearly two decades studying glycine, and he makes the case that this "nonessential" amino acid may actually be the body's primary regulator of inflammation. Unfortunately, most of us are falling short by as much as 10 grams a day… which translates to a shockingly wide range of health problems today. You'll learn: Why glycine is technically "nonessential," and why your body likely can't make nearly enough of it on its own Why meat eaters surprisingly have less glycine in their blood than vegans How glycine acts as a molecular gatekeeper, controlling whether immune cells stay calm or launch a full inflammatory response Which modern eating habits may be driving a glycine deficiency Why higher natural glycine levels translate to a lower risk of major cardiac events New research on how restoring glycine to aging cells can reverse markers of mitochondrial aging Why Dr. Brind believes chronic, unresolved inflammation after everyday injuries like sunburns or sprains isn't actually "normal" The difference between getting glycine from food, collagen, magnesium glycinate, or a standalone supplement, and what each does and doesn't provide Practical, everyday ways to close the "glycine gap" without overhauling your entire diet If you've ever wondered why nagging aches, poor sleep, or slow recovery seem to be your "normal," this conversation offers a compelling, science-backed reason why they might not have to be.

    Why Our Brains Are Shrinking, with Dr. Michael Crawford

    IN THIS EPISODE Are our brains shrinking? According to my guest this week, the answer is a resounding yes… and he's been warning us about it since 1972. In this episode of the ReThink Health Podcast, I sit down with Dr. Michael Crawford, a pioneering nutritional scientist and one of the first researchers in the world to identify DHA (docosahexaenoic acid) as essential to brain development and function. Nearly 40 years ago, his lab discovered that primates deprived of omega-3 fatty acids developed severe self-harming behavior, hair loss, and psychological distress that reversed once DHA was restored to their diet. Since then, the evidence has only grown. Dr. Crawford walks us through the astonishing story of how the human brain evolved in the sea over 500 million years, why larger-bodied animals are actually worse at making their own DHA, and why average human brain capacity is rapidly shrinking. We also get into the controversial and often misunderstood topic of mercury in seafood, why pregnant women may be doing more harm than good by avoiding fish, and what groundbreaking new research is revealing about DHA's role in brain development before birth. You'll learn: Why brain tissue is fundamentally different from the rest of the body, and why government nutrition guidelines miss this entirely The staggering economic cost of brain disorders, and why it now outpaces heart disease and cancer combined The real reason ultra-processed foods are stripped of omega-3s, and why that matters more than you might think The truth about mercury in seafood, and why its "danger" is far less significant than we've been told What Japan's coastal restoration projects can teach us about rebuilding our own fisheries and food systems The best food sources of DHA, including surprising picks for people who don't eat fish If you're not eating seafood on a regular basis, this episode makes a compelling case for why that one change could matter more than almost anything else you do for your brain.

    Is Caffeine Helping or Hurting You? with Stephen Cherniske

    IN THIS EPISODE Is your morning coffee helping or hurting your health? The answer may depend on much more than how many cups you drink. In this episode of the ReThink Health Podcast, I sit down with nutritional biochemist Stephen Cherniske, author of Caffeine Blues, for a nuanced look at one of the most widely consumed compounds in the world: caffeine.  Rather than labeling caffeine "good" or "bad," Stephen explains why your dose, timing, genetics, and individual response can completely change how caffeine affects you. Stephen (who still drinks coffee himself) encourages understanding your own physiology and using caffeine strategically rather than mindlessly; a distinction that becomes especially important since people can metabolize and respond to caffeine very differently. You'll learn: Why caffeine doesn't actually give your body energy (and what it does instead) The research-backed benefits of caffeine for cognition, memory, athletic performance, and metabolic health Why the same amount of caffeine may make one person feel great and another anxious, jittery, or unable to sleep How caffeine can interfere with deep, restorative sleep even when you think you're sleeping just fine How your heart rate and sleep quality may provide clues about your personal caffeine tolerance Why caffeine timing matters (and when Stephen recommends cutting yourself off for the day) Why tea may feel different from coffee for people who are sensitive to caffeine What to look for when choosing a high-quality decaf coffee If coffee is one of the first things you reach for every morning, this episode will help you stop thinking about caffeine as simply "healthy" or "unhealthy" and start asking a much more useful question: How is it actually affecting you?

    Is Processed Meat Really Bad for You? with Dr. Frederic Leroy

    IN THIS EPISODE Most of us hear the words "processed meat" and immediately think unhealthy. But is a traditionally fermented salami really the same thing as an ultra-processed meat snack packed with sugar, fillers, and additives? In this episode of the ReThink Health Podcast, I sit down with Dr. Frederic Leroy, a professor and food scientist who has spent decades studying animal-source foods, fermentation, food processing, and human nutrition. Dr. Leroy explains why lumping every processed meat into one category misses some important details. (Humans have been drying, curing, smoking, and fermenting meat for thousands of years, and traditional products can look very different from modern ultra-processed versions!) It's a refreshingly nuanced conversation that moves beyond "processed meat = bad" and asks a much more useful question: What kind of processing are we actually talking about? You'll learn: The difference between traditionally processed and ultra-processed meat products What the WHO's processed-meat classification actually tells us about hazard vs. risk Why much of the processed-meat research relies on observational data, and why that matters How traditional fermentation, curing, drying, and smoking preserve meat How to spot a higher-quality processed meat by reading the ingredient list What nitrates and nitrites actually do in cured meats (and why celery-derived nitrate is still the same molecule) What we know (and don't know) about probiotics, postbiotics, and bioactive peptides in fermented meats Dr. Leroy's simple framework for building a nourishing diet without following rigid food rules If you've been avoiding ham, salami, jerky, or meat sticks because you've heard that all processed meat is unhealthy, this episode will help you understand the important differences that rarely make it into nutrition headlines.

    75% of People Are Missing This Critical Nutrient, with Dr. Philip Calder

    IN THIS EPISODE You've probably heard that omega-3s are good for you. But few people realize just how crucial they are for brain health, inflammation, and so much more… and just how many of us aren't getting enough. In this episode of the ReThink Health Podcast, I sit down with Dr. Philip Calder, Professor of Nutritional Immunology at the University of Southampton and one of the world's leading researchers on omega-3 fatty acids and inflammation. According to Dr. Calder, an estimated 75% of people worldwide aren't getting enough EPA and DHA, the omega-3s most strongly linked to human health. And over time, low omega-3 status may contribute to greater risk of cardiovascular disease, metabolic disease, cognitive decline, and other conditions associated with aging. Come explore why DHA is especially important for the brain, how omega-3s may support muscle as we age, the nuanced truth about omega-6 seed oils, and simple ways to improve your omega-3 status through food and supplements. You'll learn: How omega-3s change your cell membranes and influence how your cells function How EPA, DHA, and DPA literally help turn off inflammation Why DHA plays a unique role in the brain, vision, and cognitive function The difference between EPA and DHA (and why you need both) How omega-3s may support muscle protein synthesis and healthy aging The surprising connection between omega-3s, fertility, pregnancy, and infant development Why the balance between omega-6 and omega-3 fatty acids matters The best food sources of EPA and DHA, and how much Dr. Calder recommends getting each day How the Omega-3 Index can help reveal your long-term omega-3 status and future health risks If you're not regularly eating fatty fish, there's a good chance you're missing out on these critical fats. This episode explains exactly why omega-3s matter and the practical steps you can take to get more of them.
