Can Early Life Stress Show Up in My Gut? Dr. Emeran Mayer

A hard start in life can still be shaping your gut decades later.

Dr. Aimie speaks with Dr. Emeran Mayer, gastroenterologist, neuroscientist and Distinguished Research Professor at UCLA, about how early life stress reaches the gut, the immune system and the brain. He explains increased stress responsiveness, his term for how a difficult birth or childhood becomes biology, and why it does not mean you are doomed.
They also talk about why brain fog may start in the gut, the mucus layer that protects the gut wall, and the foods that help it, from diverse fiber to fermented foods.
