In a context where the links between diet and mental health are increasingly being studied, Guillaume Fond, a psychiatrist, unveils in his October 13th video the major advances in psychonutrition.

This document explores in detail the concepts of the gut-brain axis, the impact of nutrients such as omega-3s, and the path toward better dissemination of knowledge in psychonutrition.
