How to Repair and Nourish Your Gut | Dr. Giulia Enders

Dr. Giulia Enders, a physician and microbiome researcher, explores how your gut shapes health across digestion, immunity, mood, sleep, and metabolism. She explains the mechanisms behind common gut problems, why ultra-processed foods damage your microbiome, and practical interventions—from fiber intake to meal timing—that don't require extreme diets or expensive supplements. The conversation bridges the gap between cutting-edge microbiome science and actionable advice you can implement immediately.
