Omega-3 fatty acids are essential for health. Since our bodies don’t make them, we need to get these fats from foods or supplements.
Despite some conflicting studies, most medical experts and health organizations recommend 250 to 500 milligrams of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) per day, first from fatty fish, but if not possible, from supplements. Eating seven to eight ounces of oily fish weekly provides an average of 250 milligrams of EPA and DHA per day. The American Heart Association agrees with this recommendation for healthy people without coronary heart disease.
