"Our gut microbiome had a big deal in protecting us and teaching the immune system who's a good guy, who's a bad guy." - Dr. Steven Gundry

I welcome back controversial cardiologist-turned-nutrition expert Dr. Steven Gundry to discuss his latest book, Gut Check, where he shares groundbreaking insights on how our microbiome influences everything from mental clarity to longevity. As a former heart surgeon who now sees patients six days a week, Dr. Gundry revealed why both neurologists and cardiologists are now obsessed with gut health—because as Hippocrates said 2,500 years ago, "All disease begins in the gut." We explored how leaky gut leads to systemic inflammation and accelerated aging, plus practical ways to repair your gut barrier and restore your internal "tropical rainforest" of beneficial bacteria. Dr. Gundry also challenged popular "Blue Zone" myths, arguing that longevity hotspots aren't plant-based paradises but rather communities of active people consuming fermented foods, animal products, and engaging in consistent physical activity on hilly terrain.
