Omega-3 is an essential fatty acid (EFA), consisting of EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid). Oily fish, including anchovies, sardines, mackerel, and salmon, are the only known natural sources of Omega-3 EPA/DHA. ALA is found in plants, such as flax and chia. It is important to note that only EPA and DHA contribute to the many health benefits associated with Omega-3. While the body can convert ALA into EPA/DHA, it does so very inefficiently (less than one percent), making it impossible to derive Omega-3-related health benefits from plant sources. Furthermore, although Omega-3 EPA/DHA is vital to overall good health, the human body is not able to produce it on its own, so supplementation is required, either by eating oily fish or foods fortified with Omega-3 EPA/DHA, or by taking fish oil supplements.
Eating fatty fish decreased the lipophilic index in people with impaired glucose metabolism or coronary heart disease, according to a new study from the University of Eastern Finland.
