DHA and EPA, two types of omega-3 fatty acids, are important for brain development and are associated with lower risk of depression and better mood, the expression of emotion and concentration, says Rachael Moeller Gorman in EatingWell Magazine. Omega-3 fatty acids are found mainly in fatty fish like salmon, though they can be made by the body in small amounts from ALA, another type of omega-3 that’s found in plants like flaxseed, walnuts, canola oil and soy. A variety of food, including soymilks and breakfast bars, are now fortified with DHA. Supplements of DHA/EPA made from algae are available. A good target for adults eating about 2,000 calories/day is 900 mg to 2,000 mg/day and for kids who eat about 1,000 calories/day a good target is 400-500 mg/day of omega-3s, says Joe Hibbeln, M.D. Acting Chief, Section on Nutritional Neuroscience at the National Institute on Alcohol Abuse and Alcoholism. Here are some easy foods to help you get more omega-3 fats.
