The omega-3 fatty acids are a family of important nutrients that the body can not produce and therefore must be obtained from food or supplements. Members of this family are alpha linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids play a crucial role in brain function and in normal growth and development. They can reduce the risk of chronic diseases like heart disease, cancer or arthritis.
According to the Medical Center at the University of Maryland, omega-3 fatty acids appear highly concentrated in the brain and appear to play an important role in memory, cognitive performance and behavior. Children who did not get enough omega-3 when they were in the stomach, have an increased risk of developing impaired vision or nerves. Symptoms of omega-3 deficiency include fatigue, poor memory, dry skin, heart problems, mood swings or depression and poor circulation.
