Nutrition, Mental Health & Behavioral Science

The idea that diet and mental wellbeing are connected has moved from intuition to a rapidly maturing field of research. Nutrition, Mental Health & Behavioral Science sits at this intersection, exploring two intertwined questions: how the foods we eat influence mood, cognition, and psychological health, and how the science of behaviour shapes the dietary choices we make in the first place. It is a domain where biochemistry meets psychology, and where emerging evidence is reshaping how both nutrition and mental health are understood.

On the first front lies the growing discipline of nutritional psychiatry. Research increasingly links dietary patterns to the risk of depression and anxiety, points to the gut–brain axis as a key communication pathway, and identifies nutrients such as omega-3 fatty acids, B vitamins, and minerals as relevant to brain function. On the second front sits behavioural science — the study of why people eat as they do, and how habit, environment, emotion, and motivation drive food decisions. Understanding these behavioural mechanisms is essential to designing interventions that actually change what ends up on the plate.

Bringing these strands together gives the field its distinctive value: knowledge of what supports mental health through diet means little without the behavioural tools to help people adopt it. Psychiatrists, psychologists, dietitians, behavioural scientists, and researchers will find rich, cross-disciplinary material in this area, particularly those advancing diet and mental health research and practice. A session like this rewards anyone at the Nutrition Conference curious about the mind–food relationship — illuminating both the science of how nutrition affects the brain and the behavioural strategies that turn dietary knowledge into lasting change.
