Possible Effects of Omega-3 Fish Oil According to Research
How can fish oil with omega-3s fit into a healthy diet, which foods contain it, and when might a supplement make sense? This article covers the key research on these essential fatty acids.
Omega-3 Fatty Acids
Omega-3 fatty acids are essential fats. Since the body can’t make them on its own, we need to get them from food or supplements.
The three main types are:
- ALA (alpha-linolenic acid),
- DHA (docosahexaenoic acid), and
- EPA (eicosapentaenoic acid).
ALA is mainly found in plants, while DHA and EPA are mostly present in animal-derived foods and algae. Foods rich in omega-3 fatty acids include fatty fish, flaxseed, chia seeds, flaxseed oil, and walnuts.
What Are Omega-3 and Omega-6 Good For?
Omega-6 fatty acids are also essential, just like omega-3s. Both help make signaling molecules called eicosanoids, which support functions such as blood clotting. People usually consume more omega-6 than omega-3, so keeping these fats in balance matters for overall health.
