Regular consumption of oily fish may help protect against vision loss caused by wet age-related macular degeneration (AMD), European researchers say.
They found that people who consumed the most (300 milligrams a day or more) of fish-based omega 3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were 70 percent less likely to have wet AMD, United Press International reported.
The study was published in the American Journal of Clinical Nutrition.
"This is the first study in Europeans to show a beneficial association on wet age-related macular degeneration from the consumption of oily fish and is consistent with results from studies in the United States and Australia," study leader Astrid Fletcher, of the London School of Hygiene & Tropical Medicine, said in a news release.
She noted that two, 3-ounce servings per week of oily fish such as salmon, tuna or mackerel provide about 500 milligrams of DHA and EPA per day, UPI reported.
