Dr. Kumar dives into the hidden global crisis of zinc deficiency: covering its fundamental biology, landmark clinical cases, RDA versus optimal dosing, ancestral insights, and practical tips to ensure you aren’t one of the two billion people missing out on this essential micronutrient. Episode Highlights Why Zinc MattersDiscover how this tiny mineral powers hundreds of enzymes and controls key gene switches that keep you healthy.Life-Saving DiscoveriesHear the true stories of zinc reversing stunted growth in Iran and curing a once-fatal genetic disease.Core Body FunctionsLearn how zinc supports immunity, wound healing, hormone balance (insulin, thyroid, testosterone, stress) and brain health.Optimal DosageFind out why the basic RDA may fall short, what ancestral diets suggest, and why 15–20 mg per day hits the sweet spot.Food and Prep TipsSee which foods pack the most zinc (oysters, meat, legumes), simple soaking or fermenting tricks to boost absorption, and when to supplement.Next StepsSpot the top signs of deficiency and get practical actions you can take today to make sure you’re not one of the two billion missing out. Show Notes In this episode you’ll learn: • What zinc really does in the body as a cofactor for over 300 enzymes and 1,000 transcription factors • The groundbreaking cases that put zinc on the map (Prasad’s Zinc Dwarf in Iran; Barnes & Moynahan’s cure of acrodermatitis enteropathica) • How zinc fingers, superoxide dismutase, matrix metalloproteinases and other molecular players keep us running • Zinc’s critical roles in hormone production (insulin, thyroid, testosterone, cortisol) and immune defense (thymulin, NK cells, cold lozenges) • Clinical evidence for growth recovery, wound healing, blood-sugar control and cognitive benefits • Why standard RDAs may only prevent severe deficiency and how transporter biology and ancestral diets point to 15–20 mg/day as optimal • Food-first strategies (oysters, red meat, dairy, legumes) and traditional prep methods (soaking, fermenting) to neutralize phytates • Why zinc glycinate is the gold-standard supplement, and dosing recommendations for omnivores, vegetarians and vegans Subscribe & Follow • Podcast Signup: https://drkumardiscovery.com/podcast-signup/ • Apple Podcasts: https://podcasts.apple.com/us/podcast/the-dr-kumar-discovery/id1742083523 • Spotify: https://open.spotify.com/show/3UJhg3Y5jjLP8zO6hbpwfT?si=44Db8cYwQaCeNQes6ET5OA • Amazon Music: https://music.amazon.com/podcasts/109f8c48-0168-43f3-a7ed-f0315473fb84/the-dr-kumar-discovery • YouTube: https://www.youtube.com/@TheDrKumarDiscovery Support the Show If you found this episode valuable, please: • Share it with someone you care about • Leave a rating or review on your podcast app • Subscribe for future episodes • Visit DrKumarDiscovery.com for blogs, transcripts, and more • Follow on Instagram: https://www.instagram.com/thedrkumardiscovery/ • Follow on Facebook: https://www.facebook.com/thedrkumardiscoveryReferences & ResourcesDiscovery of Human Zinc Deficiency: Its Impact on Human Health and DiseaseZinc Deficiency and Human Health: Etiology, Health Consequences, and Future SolutionsZinc and immune function: the biological basis of altered resistance to infectionRole of Zinc in Health and DiseaseZinc and the special sensesZinc Deficiency - StatPearlsDiscovery of human zinc deficiency and studies in an experimental human modelZinc Transporters and the Cellular Trafficking of ZincZinc Deficiency in Acrodermatitis Enteropathica: Multiple Dietary Intolerance Treated with Synthetic DietZinc and Immune Function: The Biological Basis of Altered Resistance to InfectionThe effects of zinc supplementation on wound healingZinc Deficiency in Humans: Discovery and ImpactZinc supplementation improves glycemicEffect of zinc supplementation on thyroid hormoneZinc status and serum testosterone levelsEffect of Zinc Supplementation on GHZinc acutely and temporarily inhibits adrenal cortisolZinc and the aging brainEffects of zinc supplementation on cognitive functionEffects of Zinc Supplementation on Inflammatory and Cognitive ParametersImproving Cognitive Function with Nutritional Supplements in AgingSerum thymulin in human zinc deficiencyEffects of zinc deficiency on Th1 and Th2 cytokine shiftsZinc enhances the number of regulatory T cells in allergen-stimulated cellsShort-term oral zinc supplementation enhances Natural Killer cell functionalityZinc lozenges and the common coldAntioxidant Role of Zinc in SOD1Clinical Effectiveness of Zinc Supplementation on Oxidative StressZinc, aging, and immunosenescenceZinc decreases C-reactive pro...
