Hyaluronic acid: Most important DIETARY fiber of all?
We’ve been urged to include plenty of dietary fiber in our daily routines, fibers that come from vegetables, legumes, grains and other plant sources. But there is an animal-sourced fiber that has nearly disappeared from the modern human diet: hyaluronic acid. Hyluronic acid has nearly disappeared from the diet because it is primarily sourced from animal products, especially organ meats like brain, skin, and tongue. But hyaluronic acid is a fiber crucial for the health of many human organs: skin, joints, uterus, cervix, vagina, arteries. It is also a fiber with significant benefits on the gastrointestinal microbiome that, in turn, yields substantial benefits via microbial metabolites. In this episode of the Defiant Health podcast, let’s discuss the role of this important fiber and how to bring it back into your lifestyle to obtain its many benefits._________________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here.Support the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

The REAL way to stop or reverse heart disease
Misguided cholesterol advice has left many treating the symptoms of heart disease with medications like statins, yet these haven't significantly reduced heart-related events. Recent discussions challenge this focus, advocating for natural lifestyle changes instead. Nutrition and gut health emerge as key players in reversing coronary atherosclerosis. The podcast also delves into the importance of understanding advanced lipid profiles and dietary modifications that can empower individuals to tackle heart disease more effectively.

Will eating yogurt change your life?
Go to any supermarket and you will see the impressive variety of products in the dairy aisle labeled "yogurt." You have a mindboggling collection of choices: non-fat, low-fat, full-fat, flavored, unflavored. Single-serve cartons, quart containers, squeezable tubes, jars. Will consuming any of these products change your life in any significant way? Will you be heathier, have better bowel health, skin health, metabolic health, mental health? Let’s discuss why, no, you will not experience any dramatic life-altering effects from consuming these products. They may be tasty, but they will not change your life in any meaningful way. But, by modifying what we call yogurt, you CAN create something that looks and smells like yogurt but DOES provide substantial life- and health-changing effects. __________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

Cold Water Immersion: Cardiac Russian Roulette
Cold water immersion is gaining traction for its touted benefits, but it's not without peril. The plunge can trigger dangerous heart conditions like coronary spasms, especially in those with endothelial dysfunction. The concept of 'autonomic conflict' complicates matters further, as both nervous system branches engage simultaneously. Litigation is on the rise due to sudden cardiac incidents linked to this practice. Safer alternatives, such as progressive cold showering, are recommended for those seeking similar benefits without the associated risks.

Why Cutting Calories is Dangerous
Over 50% of Americans are, at any one time, trying to lose weight. So it’s understandable that the GLP-1 agonist drugs like Ozempic and Mounjaro have become so popular, given their spectacular upfront results. Others have used reduced calorie diets in their various forms: counting points, assigning foods red, yellow, or green lights, meal replacement products, etc. Or bariatric procedures like lap-band, jejunoileal bypass, or gastric bypass. But there is a lot that people are not told about these methods. The near-term prospect of losing weight is so enticing to people and so profitable to doctors, the healthcare system, and the pharmaceutical industry that is simply no incentive to tell you the full story. So let me fill you in on the real story, the full details about why cutting calories, regardless of the form it takes, can be so dangerous. _________________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

Dr. Eric Westman on the Power of Limiting Carbohydrates to Reverse Type 2 Diabetes; Cholesterol is not a disease
Dr. Eric Westman, a renowned physician and researcher specializing in low-carb and ketogenic diets, discusses his groundbreaking trials that challenge conventional dietary guidelines for type 2 diabetes. He reveals how a very low-carb diet has helped participants reduce dependency on insulin and improve blood glucose levels. The conversation touches on the importance of quality foods, dietary education for healthcare providers, and the often-overlooked role of fats and cholesterol. Westman urges a reevaluation of our understanding of food addiction and the benefits of personalized dietary approaches.

Are health coaches the future of healthcare?
We all recognize that American healthcare is a badly broken system. Wildly overpriced, exploitative, with a focus on pharmaceuticals and medical procedures to the exclusion of basic issues such as nutrition, the role of nutrients, and the microbiome. Can we expect doctors, healthcare executives, pharma or medical device executives to find better solutions? I highly doubt it. One of the problems plaguing conventional delivery of healthcare is that doctors lack the time, knowledge, and frankly the interest in spending more time with their patients, hearing about their issues, then creating solutions that address their unique concerns. Enter the age of health coaches. A number of years ago, when I first heard about this phenomenon, of heath coaches playing a role in the delivery of health, I was skeptical. But over the past decade, as I’ve worked with health coaches, witnessed what they could accomplish, and heard plenty of positive feedback from the public engaging their services, my opinions about health coaching has completely changed. I now see them as part of the engine that will drive improvements in healthcare. I therefore tracked down Sandra Scheinbaum, a Phd clinical psychologist who counseled patients for many years but then diverted her career into functional medicine and health coaching, bringing the unique insights into human behavior and emotions that came from decades of practicing clinical psychology, now applied to health coaching. Dr. Scheinbaum founded the Functional Medicine Coaching Academy that educates and trains people in acquiring the skills and knowledge to practice as a health coach. She is also author of several books including Functional Medicine Coaching: Stories from the Movement That's Transforming Healthcare, and her newest book, Your Health Coach Will See You Now available in April 2025 on Amazon and selected bookstores. In this episode of Defiant Health, Dr. Scheinbaum recounts how she made this change in direction and what she foresees for the future of this important phenomenon of health coaching.For more information:FunctionalMedicineCoaching.org___________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go Support the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

Is blue light damaging your eyesight?
Over the past decade, most of us have converted our home lighting to light-emitting diode (LED) bulbs, as they save a significant amount of energy, requiring 75-90% less energy than older incandescent lights. Personally, I converted the 50 or lightbulbs in my house to nearly all LEDs.Most current LEDs emit, of course, visible light. But they also emit a significant amount of blue light and very little red and infrared (IR), in contrast to old-fashioned incandescent bulbs that emit some blue and a lot of red and IR. Remember when you had to change an incandescent bulb when it died? If you tried to unscrew it, it could burn your hand because the bulb was extremely hot. That’s the effect of red and IR that generates heat. Change a LED bulb and you can do so immediately, as the bulb is cool, even after dying just moments earlier. This is due to the absence of significant amounts of red and IR.While well-intended to save energy, it is now becoming clear that the wholesale conversion to blue-emitting LED lighting has been exerting adverse health effects, especially visual. So let’s begin talking about the role of light, specifically blue wavelengths in this episode of the Defiant Health podcast, then about the role of red and IR in a future episode. _______________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed

Managing Endotoxemia: Key to SO Many Aspects of Health
I’ve touched on the topic of endotoxemia in past episodes of the Defiant Health podcast. In this episode, let’s dive deeper into this topic that is absolutely crucial to understanding and managing SO many aspects of health, from subduing anxiety and panic, to depressive, to joint pain and skin rashes, to gastrointestinal conditions, even weight management. What is endotoxemia? Fecal microbes, so-called Gram-negative species because of the way these microbes take up stain for examination under a microscope, species such as E. coli and Salmonella, have something called lipopolysaccharide endotoxin in their cells walls. Other species, so-called Gram positive species such as Enterococcus, Staphylococcus, and Streptococcus, that stain in a different manner, have something called lipoteichoic acid in their cell walls. When these microbes die, both Gram-negative and Gram-positive, these toxic factors are released into the intestines. If these fecal microbes are confined to the colon, where they belong, a section of GI tract adapted to their presence, the entry of these toxic components are limited and current evidence is unclear in how importat this process is. The real trouble occurs, however, when fecal microbes have invaded the 24-feet of small intestine, a process we label small intetinal bacterial overgrowth, or SIBO, because the small intestine—the stomach, duodenum, jejunum, and ileum are not well-adapted to the invasion of fecal species. Here, they die, release their toxic components, which then enter the bloodstream, the process labeled endotoxemia. People with SIBO therefore have high blood levels of endotoxin. This is how microbes in the GI Tract export their effects to other parts of the body. Let’s discuss this process and how you can take control over your emotions, mood, sleep, energy, weight, and numerous other aspects of health. _______________________________________________________________________________For BiotiQuest probiotics including Sugar Shift, go here.A 15% discount is available for Defiant Health podcast listeners by entering discount code UNDOC15 (case-sensitive) at checkout.*_________________________________________________________________________________Get your 15% Paleovalley discount on fermented grass-fed beef sticks, Bone Broth Collagen, low-carb snack bars and other high-quality organic foods here.* For 12% off every order of grass-fed and pasture-raised meats from Wild Pastures, go here._____________________________________________________________________________MyReuteri and Gut to Glow can be found here: oxiceutics.comSupport the showBooks: Super Gut: The 4-Week Plan to Reprogram Your Microbiome, Restore Health, and Lose Weight Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health; revised & expanded ed
