Can what you eat actually treat depression? In this episode of The Ty Beal Show, Dr. Ally Jaffee, MD, a psychiatry resident doctor and co-founder of NutriTank, reveals the science behind nutritional psychiatry and why your gut health might be the key to mental wellness.

Dr. Jaffee, winner of the 2024 Cura Mental Health Advocate of the Year Award, shares her deeply personal journey into psychiatry—from losing her grandfather to suicide at two weeks old to experiencing her own clinical depression during medical school. Her story illuminates the concept of the "wounded healer" in healthcare and how lived experience can enhance, rather than compromise, clinical practice.

Drawing from landmark research including the SMILES trial—the first randomized controlled trial to show dietary intervention could put depression into remission—Dr. Jaffee explains how the gut-brain axis creates a bidirectional pathway between our digestive system and mental health. She breaks down why people with inflammatory bowel disease have higher rates of mental illness, and how restoring gut microbiome balance can enhance both mood and medication effectiveness.
