Fish oil is one of the most popular supplements on the market—and it’s no surprise why. Fish contains essential omega-3 fatty acids, one of the best superfoods out there. These fatty acids are linked to immune support, increased wellness, and longevity. Omega-3s are so important to our health that even the government has made a point to recommend them.Fatty acids are essential for our body systems, including the circulatory and respiratory systems, skin and hair health, brain, and other organs. Of the essential fatty acids, three are the most critical: omega-3, omega-6, and omega-9. However, our bodies cannot produce omega-3 and -6, so we have to ingest them.Omega-3 fatty acids are polyunsaturated acids (PUFAs)—meaning they contain more than one double bond.
Omega-3 acids are essential fatty acids. Since the body does not produce them, they must be consumed from food or supplements. The main food source of Omega 3s (DHA and EPA) is seafood while ALA is found in flaxseed, soybean, and canola oils.
Omega-6 fatty acids are also polyunsaturated essential fatty acids but differ in chemical composition from Omega 3s. The main sources of Omega-6 fatty acids are corn, soybean and canola oils, borage oil, and evening primrose oil. The most common Omega-6 fatty acids are linoleic acid and GLA (gamma-linolenic acid). Linoleic acid supports heart health and reduces LDL cholesterol.Omega-9 fatty acids are monounsaturated fatty acids (MUFAs), meaning they only have one double bond. They are not essential fatty acids since the body can produce them, but you can consume them. Two great sources of Omega 9 are olive oil and avocados. They are important for good health. The Mediterranean diet is high in MUFAs.
