Happiness Is... A Filet of Fish
It's no secret that eating fish is good for you. The omega-3 fatty acids found in abundance in cold-water fishes are well-documented to have an association with a lowered risk for heart disease.
The best fish for dietary omega-3 include salmon, mackerel, tuna, lake trout, and sardines. The purpose of a study in the American Journal of Psychiatry
was to determine if a
specific omega-3 acid called "E-EPA" prevents clinical depression.
Twenty people with major depressive disorder were divided into two equal groups and given either two grams per day of an omega-3 supplement or a placebo, along with their current antidepressant drug therapy. The supplement contained 96% pure fish oil. Patients were followed for four weeks; a depression rating scale was administered to evaluate depression.
Significant improvements from adding E-EPA to therapy were observed by the third week of the study. Six of 10 patients taking the fish-oil supplement noted a 50% reduction in their depression levels, while only one of 10 patients taking the placebo saw a similar reduction. The omega-3 supplement reduced depressed moods, feelings of guilt and worthlessness, and insomnia; no side effects were reported.
The authors of the study caution that they are unsure whether E-EPA works independently as an antidepressant, or simply amplifies the effects of antidepressant drugs. Regardless, fish and fish oil containing omega-3 acids have numerous other health benefits, and fish are excellent sources of protein.
