Mental health, cognition, mood, and behaviour are shaped by a complex interplay of social, environmental, and biological factors. But one factor often gets left out: nutrition.

What people eat — and what they don’t — plays a fundamental role in brain function, emotional wellbeing, resilience, and long‑term mental health. 

Good nutritional status helps support healthy brain development and function — and may influence outcomes in anxiety, depression, neurodevelopmental conditions (e.g. ADHD, autism), eating disorders, cognitive decline, and other psychological or behavioural problems. 

Diet is more than calories: it’s a modifiable influence on mental health that is often overlooked — but easily addressed.

How Psychologists Can Benefit from Food and Behaviour Research (FAB)

• Evidence‑based insight — We collate peer‑reviewed research on how diet and nutrition affect the brain, mood, cognition, and behaviour, making it accessible and relevant for psychological practice.

• Practical tools and resources — Webinars, factsheets, and guides tailored to mental health and behaviour — useful for psychological assessment, psychoeducation, and holistic care.

• Support for collaborative care — Psychological work often intersects with physical health, dietetics, social factors — FAB fosters a network linking psychologists with nutrition researchers, dietitians, and other practitioners.

• Continuing professional development — Stay up to date with emerging evidence in nutritional neuroscience and mental health, and integrate nutrition-informed approaches into therapy, assessment, or consultation.
