Extensive evidence now supports associations between diet quality and mental and brain health across the lifespan. This includes in early life; nutrition preconception and during pregnancy is of substantial relevance to emotional and cognitive outcomes in children. Experimental evidence also shows that dietary improvement is an efficacious and cost-effective treatment for even severe clinical depression. Mechanisms are many, but particularly include the gut and its resident microbiota. There is enormous potential for both clinical and public health interventions focused on nutrition for the prevention and treatment of mental, neurodevelopmental, and neurodegenerative disorders. This presentation will briefly cover the existing evidence base, then present new data and insights arising from studies recently conducted at the Food & Mood Centre, including a large systematic literature review of the gut microbiota in mental disorders, and several randomised controlled trials focused on diet, the gut microbiota, and mental and brain health (new, unpublished data). The talk will conclude with an overview of the new studies and translation and education activities currently underway at the Centre, and an update on the impact on policy and clinical guidelines of the field of Nutritional Psychiatry.
