Omega-3 fatty acids include alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). Your body needs omega-3s; they appear in the membranes that surround every cell in your body. Some people take omega-3 supplements such as cod liver oil, but with a little dietary care, you should be able to obtain adequate omega-3s from your daily nutrition. ALA is available in plant-based oils, especially flaxseed and canola oils. Some leafy greens, wheat germ, and walnuts also contain ALA. DHA and EPA occur naturally in fatty fish such as tuna, mackerel, sardines, bluefish, and salmon. Vegetarians may obtain some DHA and EPA from algal sources.
The positive effects on health of a diet rich in omega-3s are clear, although further research is needed to know exactly how omega-3s help. They seem to reduce inflammation, lower blood pressure, and reduce the buildup of plaque in the arteries, making them critical in maintaining heart health. Researchers have found that people with a high omega-3 intake seem to have fewer colon and breast cancers. Because of the fatty acids’ effect on inflammation, some doctors find omega-3 supplements useful for asthma and arthritis patients.
Less clear are the effects on mental health, although there are health professionals who believe strongly that high levels of omega-3s can reduce depression, improve memory, and moderate symptoms of attention deficit hyperactive disorder. Until more research takes place, it is unwise to rely on omega-3s to cure mental health issues. However, ensuring that your diet contains ample amounts of these critical fatty acids is still a good idea.
