Diet affects brains as well as bodies - and poor nutrition is a major reason why the burden of mental health disorders in developed countries has now overtaken that of physical health disorders. Links between the gut, brain and immune system operate across biochemical, physiological and psychological levels, and all are affected by our nutritional status and eating habits. The importance of major food groups and nutrients will be outlined, emphasising links between diet and various psychological symptoms and disorders, and summarising the latest research evidence in this area.

Fortunately neuroplasticity is a fact and in this presentation we will look at the evidence that food deprivation can lay the foundations for mental disturbances. We will examine how intensive introduction of new foods such as Omega 3 can transform the psychological and emotional state of people with severe mental disturbance, and how that occcurs.

Although problems ranging from mild mood disorders to severe psychoses can arise from poor nutrition, in association with other factors, putting that right may be unfamiliar territory for the psychotherapist. We will consider both diagnosis of dietary issues, how that is explored in the therapy relationship and what may be done if a dietary deficiency is apparent.

Nutrient deficiencies and imbalances often give rise to particular physical and mental symptoms. Signs to look for, questions to ask about food and diet, and possible diagnostic tests or specialist referrals will be discussed in relation to particular psychological problems. These can often be extremely revealing, giving an additional perspective on mental health problems that can significantly enhance therapeutic progress and assist clients in their recovery.
