What does your diet have to do with your mood? Is mercury in fish really dangerous? Psychiatrist Dr. Drew Ramsey joins Michael Shermer to discuss the science behind nutritional psychiatry and how food, sleep, exercise, and social habits influence brain health. They explore why mental health issues are rising—especially among teens—and what role parenting, social media, and modern lifestyles play.

The conversation also covers the effectiveness of SSRIs and other treatments, the role of inflammation in mental health, and the importance of sleep and tracking sleep quality.
