Depression is a common and serious mental disorder. A new 21-study meta-analysis of diet and depression found that eating a healthy diet (high fruit, vegetable and whole grain intake) lowered the risk of depression by 16% compared to the average. A"western diet" (high in refined grains, processed meat, snack foods high in sugar and saturated fat) raised the risk by 17%. A very interesting association, but not yet causal proof.
PositiveTip: Eat a healthy diet and get exercise–it could help reduce your risk of depression.
