People who include seafood in their weekly diet lower their risk for depression, according to a study from The Second Xiangya Hospital of Central South University in China. This study compared depression risk with dietary intakes in 2,034 individuals who were at least 55-years-old. Results showed that people who ate fish at least three times a week had a 40% lower incidence of depression after controlling for age, gender, marital status, smoking and alcohol consumption, exercise, and other risk factors.
The omega-3 fatty acids in fish, DHA and EPA, improve the effectiveness of antidepressant medications, according to a study from the University of Melbourne in Australia.
In a study from Tehran University of Medical Sciences in Iran, 1000 milligrams of the omega-3s taken daily significantly lowered depression in a group of 136 depressed men.
