Omega-3 fatty acids are the kind of fats that are good for you. This “good” kind has a lot of different types, but there are three that are the most important: Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) that are found in certain kinds of fish like salmon, mackerel, and tuna; and also alpha-linolenic acid (ALA), an omega-3 fatty acid that can be found in nuts and seeds such as walnuts, flaxseed, and dark leafy vegetables. ALA, however, must be converted by the body into DHA and EPA to become beneficial.
