Docosahexaenoic acid (DHA) is the body's most important omega-3 fatty acid. It is a key structural component of the brain, the retina of the eyes and many other parts of the body (. Omega-3 fatty acids are essential for maintaining good health. Omega-3 fatty acids are found in high concentrations in fish, olive oil, garlic, and walnuts.
While these foods are common, most people don't eat them in the right amounts that would be needed to obtain beneficial levels. In addition, the body is very inefficient at converting the omega-3s in plants into the omega-3s that the body needs, which are EPA and DHA. The most common type of omega-9 fat is oleic acid. In addition, omega-9s are not essential fats, since the body can produce them.
However, a diet rich in omega-9 fats guarantees multiple health benefits.
