Cod liver oil may be good for you, but it sure tastes awful. Old-fashioned fish oil, usually in pill form, has regained its popularity as a health supplement now that the benefits of omega-3 fatty acids, found primarily in fish oils, are rapidly being confirmed.

Food manufacturers are jumping into the fray with a range of products, from salad dressing to waffles that are supplemented with omega-3s. Known primarily for keeping the heart and blood vessels fit, these fats also improve mental health. Previous studies have linked low levels of the fatty acids to higher rates of depression, bipolar disorder and suicide.

Because brain cells are encased in fat, omega-3s help maintain brain cells and keep neurotransmission fluid. Fish oils may be as effective as conventional drugs in alleviating unipolar and bipolar depression, says Andrew Stoll, director of the psychopharmacology research lab at McLean Hospital in Belmont, Massachusetts.
