How our research explores the food-mood relationship

At the Food and Mood Centre, we’re committed to understanding how your diet can significantly impact your mental health. Our diverse team of experts is dedicated to uncovering which dietary factors influence brain function and overall wellbeing. We aim to translate our groundbreaking research into practical solutions that can improve mental health for everyone.

Our research areas

Led by a team of more than 30 researchers from Deakin’s School of Medicine, our research spans several critical areas to understand the relationship between diet and mental health.

Nutritional psychiatry

We investigate how nutrients and dietary patterns influence mental health and cognitive function to develop effective, evidence-based strategies for mental health improvement.

The gut-brain axis

We explore how gut health affects brain function and mood, examining the impact of dietary choices on the gut microbiome and mental health.

Healthy aging and cognitive function

We research how diet influences cognitive health and ageing, aiming to develop dietary interventions to reduce the risk of age-related cognitive decline.

Dietary interventions for mental health

We evaluate the impact of specific dietary changes on mental health conditions, including depression and anxiety, to provide practical dietary recommendations for mental health care.

Help amplify our impact

Your support is crucial in helping us expand our research and increase its impact on the community. If you’d like to be invited to provide feedback, share your experience on panels and engage in initiatives tailored to community needs, become a Friend of the Food and Mood Centre.

All of our data shows the impact of diet on the brain, immune system and gut microbiome. The fact people can take control of their mental health and help themselves by changing their diet is a very powerful message.

Featured projects

Since 2009, our researchers have conducted extensive observational studies to highlight the significant impact of diet on mental health.

The impact of A1 and A2 dairy proteins

The impact of A1 and A2 dairy proteins

Our research delves into how A1 and A2 beta-casein proteins in cow’s milk can influence inflammation, gut health and overall wellness. By uncovering these effects, we aim to reshape dairy recommendations and help you make informed choices.

Exploring the ketogenic diet for psychotic disorders

Exploring the ketogenic diet for psychotic disorders

Though the low-carb, high-fat ketogenic diet is well-established for treating epilepsy, its effects on psychotic disorders remain uncertain. This study delves into how this diet may influence and potentially improve psychotic symptoms, aiming to reveal new treatment possibilities.
