People with type 2 diabetes often suffer from diabetic retinopathy, which causes tissue damage in the eyes and may cause vision problems or even blindness. Now, researchers in Spain believe Omega-3-rich fish oil may promote eye health and reduce the risk of developing the debilitating condition.
Using data from an existing study focusing on the benefits of Omega-3 in relation to heart health, they determined that people who consumed 500 mg of Omega-3 per day—about two servings of oily fish weekly, which is what the American Heart Association recommends—were 48 percent less likely to develop diabetic retinopathy.
“The incidence of diabetes mellitus type 2 is increasing, and therefore more individuals will suffer from diabetic complications which, if not properly managed, may lead to permanent eye damage. People should be aware that regarding diet, even small changes in the right direction can lead to substantial benefit for themselves,” said lead author Aleix Sala-Vila in a recent statement.
Sala-Vila also pointed out that previous research has linked a diet rich in Omega-3 with eye health in general, along with a healthy heart and brain. Results of the study were published last month in the journal JAMA Ophthalmology.
