The Mountain Life welcomes Dr. Steven Gundry back to the show. Gundry has written The Longevity Paradox . Dr. Gundry reveals in his book that the gut bacteria that make up our microbiome largely determines our health over the years and says that an individual's gut bacteria can be a predictor of many health outcomes, more so than genetics. Gundry also outines the conection between gut health and the brain and how neuroinflammation is responsible for cognitive decline and degenerative conditions.
