<p>Erythritol, a popular sweetener found in countless sugar-free and keto products, has long been considered a safe alternative to sugar. This episode of Revolution Health Radio examines emerging research that challenges that assumption. Chris explains how erythritol promotes blood clotting, impairs blood vessel function, increases oxidative stress, and interferes with the body’s ability to dissolve clots. You’ll learn why erythritol accumulates in the bloodstream, how regulatory loopholes allowed it to be widely adopted without long-term safety data, and why people with diabetes, obesity, and heart disease may be especially vulnerable. Chris also discusses similar concerns with xylitol, explores gut health side effects of sugar alcohols, and outlines safer alternatives like allulose, pure stevia extract, and monk fruit.</p> <p>The post <a href="https://chriskresser.com/erythritol-the-safe-sweetener-thats-anything-but/">RHR: Erythritol: The ‘Safe’ Sweetener That’s Anything But</a> appeared first on <a href="https://chriskresser.com">Chris Kresser</a>.</p>

<p>In this episode of Revolution Health Radio, Chris Kresser is joined by neuroscientist and physician Dr. Tommy Wood to explore how cognitive function can be preserved—and even enhanced—as we age. Dr. Wood challenges outdated ideas about inevitable cognitive decline and reframes dementia as a largely preventable, multifactorial condition. The conversation covers the historical roots of Alzheimer’s disease, why “one-size-fits-all” drug approaches have failed, and how lifestyle, environment, and brain use interact to shape long-term brain health. Dr. Wood introduces his 3S model of brain health, explains why retirement may be a mismatch for brain biology, and breaks down the roles of exercise, nutrition, sleep, and cognitively demanding activities in building lifelong cognitive resilience.</p> <p>The post <a href="https://chriskresser.com/preserving-cognitive-function-as-you-age-with-tommy-wood/">RHR: Preserving Cognitive Function As You Age, with Tommy Wood</a> appeared first on <a href="https://chriskresser.com">Chris Kresser</a>.</p>

<p>In this episode of Revolution Health Radio, Chris breaks down a new large-scale study challenging the popular belief that plant-based diets promote longevity. The findings reveal that vegetarians—especially vegans—were significantly less likely to reach age 100 compared to omnivores. Chris explores the biological reasons behind these findings, emphasizing the importance of high-quality protein and nutrient bioavailability, as well as why certain nutrients may be harder to obtain from plant-only diets. He also discusses the powerful nutritional synergy that occurs when plant and animal foods are consumed together, arguing against rigid dietary dogma and advocating for a balanced, omnivorous approach to support healthy aging and longevity.</p> <p>The post <a href="https://chriskresser.com/new-study-challenges-the-plant-based-longevity-myth/">RHR: New Study Challenges the Plant-Based Longevity Myth</a> appeared first on <a href="https://chriskresser.com">Chris Kresser</a>.</p>

<p>In this episode of Revolution Health Radio, Chris sits down with gastroenterologist and microbiome researcher Dr. Zain Kassam to explore the rapidly evolving science of the microbiome and its profound impact on sleep, circadian rhythm, cognitive performance, stress resilience, immune balance, and longevity. From groundbreaking research on microbiome diversity and sleep quality to emerging innovations like cobiotics, Dr. Kassam explains how our microbial partners regulate core biological systems far beyond the gut. They discuss the connection between the gut and the brain, eyes, skin, and even ears—along with practical strategies for supporting microbial health in a modern world that constantly disrupts it.</p> <p>The post <a href="https://chriskresser.com/beyond-the-gut-the-microbiomes-role-in-sleep-energy-and-longevity-with-dr-zain-kassam/">RHR: Beyond the Gut: The Microbiome’s Role in Sleep, Energy, and Longevity, with Dr. Zain Kassam</a> appeared first on <a href="https://chriskresser.com">Chris Kresser</a>.</p>

<p>Depression and anxiety are often treated as chemical imbalances in the brain—but what if the real problem starts in the gut? In this episode of Revolution Health Radio, we dive deep into the gut–brain connection and the growing body of research linking gut inflammation, microbiome imbalance, and mood disorders. You’ll learn how inflammatory cytokines contribute to depression, why butyrate is emerging as a powerful antidepressant compound, and how specific probiotic strains can improve mental health outcomes. Chris also shares practical, evidence-based strategies—including diet, supplementation, and functional testing—to address root causes and support lasting emotional well-being. </p> <p>The post <a href="https://chriskresser.com/the-gut-brain-connection-how-your-microbiome-affects-your-mental-health/">RHR: The Gut-Brain Connection: How Your Microbiome Affects Your Mental Health</a> appeared first on <a href="https://chriskresser.com">Chris Kresser</a>.</p>

<p>In this episode of Revolution Health Radio, Chris Kresser explains why vitamin D supplementation should never be one-size-fits-all. Drawing on new research—including a groundbreaking study on magnesium’s regulatory role—Chris explores how genetics, ethnicity, body weight, age, health status, sun exposure, and nutrient cofactors all shape an individual’s vitamin D needs. He outlines optimal testing strategies, safe and effective target ranges, and the critical roles of magnesium, vitamin K2, and vitamin A in vitamin D metabolism. The episode reframes vitamin D optimization as a personalized, systems-based approach that prioritizes balance, testing, and real-world physiology over generic dosing guidelines.</p> <p>The post <a href="https://chriskresser.com/vitamin-d-why-a-personalized-approach-is-best/">RHR: Vitamin D: Why a Personalized Approach Is Best</a> appeared first on <a href="https://chriskresser.com">Chris Kresser</a>.</p>
