U.S. study says that Omega-3s—essential fatty acids of fish such as tuna or salmon can reduce dry eye syndrome, a chronic and uncomfortable eye disease which is caused by a decrease in tear production or increase in tear evaporation that makes the tears too “salty”, by 68 percent in women.
The study analyzed data from surveys collected from more than 37,000 women enrolled in the Brigham and Women’s Hospital-based Women’s Health Study.
“Our study examined the relationship between Omega-3 and Omega-6 consumption and the risk of dry eye,” said study co-author Jeffrey P. Gilbard, M.D., of the Department of Ophthalmology, Harvard Medical School. “Tuna is the major source of Omega-3 in the American diet. Vegetable oils are the major sources of Omega-6.”
