If you've been a little depressed of late, eating more fish might brighten your outlook.

A recent study presented at the American Psychiatric Association meeting shows that people who eat at least one serving of fish per week have a lower risk for depression.

At Finland's University of Kuopio, 3,204 subjects completed a questionnaire that measured symptoms of depression and how often they ate fish. Of the 30 percent of those who said they ate fish less than once a week, 28 percent reported symptoms of mild to serious depression. After accounting for other factors such as age and smoking, researchers conclude that rates of depression were a third higher for infrequent fish eaters.

The doctors say the increased risk may be associated with lower intake of omega-3 fatty acids, polyunsaturated fatty acids found in seafood that play a critical role in maintaining good health.

Other factors may be involved that were not measured, but eating foods like salmon that are rich in omega-3s can't hurt and could help individuals ward off the blues.
