Being health conscious, I came across medical news that says recent study at Harvard University has proven that omega-3 fatty acid deficiency is officially one of the top 10 causes of death in America. There are many kinds of omega 3 essential fatty acids that can be derived from food sources and supplements such as fish oil and flax oil. Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) are types of omega 3 essential fats most commonly found in fatty, cold-water fish such as mackerel, salmon, tuna, sardines, herring, trout and etc.
Fish rich in omega 3s produce both EPA and DHA from alpha-linolenic acid (ALA), a plant-based precursor to other types of omega 3 EFAs. These high omega 3 fish obtain their dietary ALA from marine Phytoplankton (single-celled aquatic organism or microscopic algae) and seaweed and convert these marine plant sources of basic ALA into more useful forms such as EPA and DHA.
