Consistently eating about 4 ounces of fish or other seafood may be the optimal amount to prevent depression symptoms, according to researchers.
A study of 1,200 adults found that those who consumed an average of 4 ounces of fish daily had a significantly lower risk for major depressive disorder (MDD). Certain brain chemicals — eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) — are found to be lower in those with depression; fish contains these brain-boosting compounds and can help alleviate depressive symptoms.
