Diet and depression

Whilst research remains at an early stage, there is some preliminary evidence that indicates that there is a link between mental health and diet. A BBC article [here] indicates that a Mediterranean diet which includes lots of fruit, fish, vegetables, nuts and cereals, may prevent depression and goes on to suggest some reasons why. Another news article [here] also indicates that junk food which contains a lot of fat or sugar, has the reverse effect and increases the risk of experiencing depression.
