In this Huberman Lab Essentials episode, my guest is Dr. Justin Sonnenburg, PhD, a professor of microbiology and immunology at Stanford University. We discuss how microbes in our gut impact our mental and physical health and how diet and the environment affect the gut microbiome. We explain how lifestyle factors such as antibiotics and Western-style diets (high fat, low fiber and rich in processed foods) can damage gut diversity and whether prebiotics or probiotics are useful tools. Throughout the episode, we highlight evidence-based dietary and lifestyle strategies for improving gut health.
