Can the diet affect on the course of mental illnesses?

An increasing number of studies provide evidence that the diet may play a role in the pathogenesis of mental disorders and their treatment. However, the evidence is so far thin.

Largely mental illnesses such as depression, anxiety disorders or schizophrenia can now be treated with medication and psychotherapy. However, as more and more studies show the diet plays a major role. In addition, the growing knowledge about the brain metabolism can prove that dietary habits or deficiency of certain nutrients can influence on the development and course of mental disorders.

Thus, epidemiological studies have shown that there is a correlation between a low intake of polyunsaturated fatty acids and the development of schizophrenia and depression. In studies have shown that the selective intake of omega-3 fatty acids has a positive effect on these diseases. Researchers assume that the intake of fatty acids alter the cell membrane and thus also may affect on the transmission between brain cells.
