Omega-3s are “essential” fatty acids because the body isn’t capable of producing them on its own. Therefore, we must rely on omega-3 foods in our diet to supply these extremely beneficial compounds.
There are actually three different types of “omega-3s”: ALA (alpha-linolenic acid), DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). The preferred sources are DHA and EPA, the kinds found in seafood sources like salmon and sardines. ALA, on the other hand, is found in some plant foods, including certain nuts and seeds, as well as high-quality cuts of meat like grass-fed beef.
When it comes to getting enough omega-3s into your diet, I recommend eating plenty of omega-3 foods and also supplementing in most cases. Through a combination of both, my advice is to make sure you’re getting at least 1,000 milligrams a day of EPA/DHA and about 4,000 milligrams of total omega-3s (ALA/EPA/DHA combined).
