In this podcast episode, the focus is on the widespread issue of stomach problems, particularly irritable bowel syndrome (IBS), and how diet and lifestyle play a crucial role. Dr. Mark Hyman highlights that a diet high in ultra-processed foods while lacking in nutrient-dense whole foods is a major contributor to IBS. He introduces the 5R program—Remove, Replace, Re-inoculate, Repair, and Restore—as a functional medicine strategy for tackling gut issues. This approach involves pinpointing and removing triggers, replenishing missing nutrients, and healing the gut lining. Additionally, the low FODMAP diet is suggested as a temporary method to ease IBS symptoms by limiting fermentable carbohydrates. The episode underscores the importance of identifying underlying issues, such as small intestinal bacterial overgrowth (SIBO), through testing and targeted treatments for lasting relief.
