EFR 919: The Gut–Brain–Immune Connection: The New Science of Inflammation and Why You Can't Heal the Gut Without Healing the Mind with Will Bulsiewicz

This episode is brought to you by Joi & Blokes , Fatty15 , and Strong Coffee Company. In this powerful conversation, Dr. Will Bulsiewicz, MD joins Ever Forward Radio to explore why true healing goes far beyond food, supplements, and exercise—and into the nervous system, emotional health, and human connection. Drawing from his new book Plant Powered Plus , Will explains how inflammation is driven by an inseparable triad of gut microbiome imbalance, immune dysfunction, and a compromised gut barrier, while also revealing how chronic stress, unresolved trauma, loneliness, and circadian disruption can prevent the body from ever feeling safe enough to heal. This episode clearly explains the gut–brain–immune axis, the role of parasympathetic "safety" states, why PTSD and trauma leave measurable signatures in the gut, and how practices like sunlight exposure, breathwork, meaningful relationships, and spiritual purpose are not "woo"—but biology.
