A study published in the Archives of General Psychiatry (2009; 66(10):1090–1098) found that diet may influence the risk of developing depression. The researchers followed the dietary habits of 10,094 adults for an average of 4.4 years, during which time 480 participants were diagnosed with depression. The study focused on adherence to a Mediterranean-style diet, characterized by high intake of fruits, vegetables, and nuts; frequent use of monounsaturated fats such as olive oil; low intake of saturated fats; limited consumption of high-fat meat and dairy; and higher intake of fish and legumes. It is an anti-inflammatory diet that is high in antioxidants. Participants who more closely followed this dietary pattern had a lower incidence of depression compared with those whose diets least resembled the Mediterranean diet.
