Macular Degeneration and Fish Consumption
You may want salmon, mackerel, herring or tuna on your menu at least once a week if you want to reduce your risk for age-related macular degeneration (AMD).
Researchers at Brigham and Women’s Hospital and Harvard Medical School followed up on 38,022 women during the 10 years after data had been collected on them for the Women’s Health Study.
After adjustments for factors including age, they found that women who consumed the most DHA (an omega-3 fatty acid found in fish) had a 38 percent lower risk of developing AMD than those who consumed the lowest amount of DHA. They found similar results for EPA, another omega-3 fatty acid, as well as for consumption of both acids together.
Low Vision Optometrists who are members of the International Academy of Low Vision Specialists are trained to assist those with vision loss in a variety of ways including nutritional counseling. They agree with the study, having one or more servings of fish per week produced a 42 percent lower risk of AMD, compared with less than one serving per month. Canned tuna and dark-meat fish were the primary types of fish that produced this lower risk.
The omega-6 fatty acids linoleic acid and arachidonic acid were also evaluated. Higher intake of linoleic acid, found in many fruit and vegetable oils such as safflower oil, grapeseed oil and corn oil, was associated with a higher risk of AMD, but not significantly so.
