How to Build, Maintain & Repair Gut Health | Dr. Justin Sonnenburg

About this video

Dr. Justin Sonnenburg, a professor of microbiology and immunology at Stanford, joins Huberman to explain the gut microbiome, the trillions of microorganisms throughout the digestive tract and also in the nose and on skin. Huberman explains that Dr. Sonnenburg describes crypts and niches, little caves in the digestive tract where certain microbiota reside and support hormonal health, brain health and immune function. They discuss fermented foods, fiber, and how behaviours such as touch, contact with animals and social interaction modify the microbiome. Dr. Sonnenburg argues that prioritising whole plant-based foods with a lot of fiber leaves little room for processed food, and he explains that gut microbiota ferment complex fibers into short-chain fatty acids such as butyrate, which he says fuel colon cells, enforce the gut barrier, keep inflammation low and help regulate immunity and metabolism.
