It appears that a Mediterranean diet or a diet consisting of foods with a low Dietary Inflammatory Index (DII) has been associated with a reduced risk of depression.[1] However, more research is needed before a specific diet can be recommended. With that being said, current research suggests that improving one's diet by replacing "junk" foods with nutrient-dense, higher fiber foods, such as vegetables, fruits, whole grains, and nuts reduce the risk and symptoms of depression.[2]

A Mediterranean diet or one that is low on the Dietary Inflammatory Index may lower the risk of depression, but further research is needed for specific dietary recommendations. Current findings suggest that replacing junk foods with nutrient-dense, high-fiber options like vegetables, fruits, whole grains, and nuts can help reduce the risk and symptoms of depression.
