Omega-3 linked with Lowered Risk of AMD

There may be a new reason to increase your intake of both fish and other foods that contain omega-3. Researchers in Australia reviewed the evidence from nine studies on dietary omega-3 and concluded that consumption of fish and other foods rich in omega-3 fatty acids twice a week is associated with a lower risk of age-related macular degeneration (AMD).

AMD is the leading cause of vision loss among adults 60 years of age and older. Thirty percent of Americans over the age of 75 have AMD. “Long chain omega-3 fatty acids constitute a large part of the neural retina (a layer of nerve cells) in the eye,” says Elaine Chong, MBBS, of the University of Melbourne and the lead author. “A higher intake of these fatty acids may protect against degenerative processes of the retina.”

Previous research has linked increased intake of omega-3 foods and supplements with decreased risks of heart disease, stroke, and hypertension, as well as easing the pain caused by rheumatoid arthritis. Inflammation is thought to play an important role in the development of AMD, as it does in heart disease, and omega-3 fatty acids apparently have an antioxidant and anti-inflammatory effect.<br><br>Food sources of omega-3 fatty acids: Salmon, and walnuts are excellent sources of omega-3 fatty acids. Very good sources of these healthy fats include scallop, cauliflower, cabbage, cloves, and mustard seeds. Other sources of these fats include halibut, shrimp, cod, tuna, soybeans, tofu, kale, collard greens, and brussel sprouts. A 4-ounce piece of salmon contains 1.5 grams of omega-3 fats.
