A group of investigators from Rush University Medical Center in Chicago conducted a study among participants of the Chicago Health and Aging Project (CHAP) into the relationship between the Mediterranean diet and depression among older adults. They found that in this large, biracial community greater adherence to a Mediterranean pattern of eating including vegetables, fruits, whole grains, fish and legumes, was associated with a decreased likelihood of developing depressive symptoms over time. The link between the Mediterranean diet and mental health may be found in a number of dietary components of the diet like B-vitamins, antioxidant nutrients, and fat components.
