In this episode, I discuss the profound effect the gut has on the nervous system. I cover the structure and function of the gut-brain axis and the role of the gut microbiome in the brain and overall health. I describe how the gut controls hunger or satiety by affecting neurons in our brain. I also contrast the many pathways by which the gut influences the brain: direct vs. indirect pathways, chemical vs. mechanical, and fast vs. slow signaling. Additionally, I discuss what defines a healthy microbiome and how your lifestyle impacts the gut microbiome, including the effects of stress, fasting, antibiotics, pets, environment, prebiotics and probiotics. I address how different foods shape the gut microbiome, in particular, the emerging data that fermented foods can increase the diversity of healthy gut microbiota. Throughout the episode, I explain peer-reviewed and textbook findings that reveal the critical role of the gut microbiome in supporting mental and physical health and I outline simple tools that anyone can use in order to enhance their gut microbiome health.
