Gut Microbiota and Mood: Can you eat your way to happiness?

This video discusses recent discoveries that reveal a link between gut microbial composition and mood disorders. It outlines the role of serotonin in the body and discusses a set of studies that test the role of gut bacteria in regulating human mood. This video also discusses the limitations in the scientific literature, future directions, and the potential use of bacteria in mood disorder treatment.

This video was made by McMaster students Hani Fakhri, Sabhat Khan, and Pukhraj Gaheer in collaboration with the McMaster Demystifying Medicine Program.
