2015 Dietary Guidelines Advisory Committee Systematic Reviews

Systematic Review Question

What is the relationship between dietary patterns and risk of depression?

Conclusion Statement

Limited evidence suggests that dietary patterns emphasizing seafood, vegetables, fruits, nuts and legumes are associated with lower risk of depression in men and non-perinatal women. However, the body of evidence is primarily composed of observational studies and employs a range of methodology in study design, definition and measurement of dietary patterns and ascertainment of depression or depressive signs and symptoms. Studies on dietary patterns in other populations such as women in the postpartum period, children and adolescents, as well as those in various ethnic and cultural groups, are too limited to draw conclusions.
