Chronic high blood sugar can damage the small blood vessels in the retina, a condition called diabetic retinopathy. In this study, doctors assessed 1,356 men and women with type 2 diabetes and found those with the highest levels of the omega-3 fatty acid DHA were 17 percent less likely to have retinopathy compared to those with the lowest DHA levels.
For those with retinopathy, the condition was 38 percent less severe in those with the highest levels of DHA, and EPA plus DHA, compared to those with the lowest levels of these omega-3 fatty acids. Adding omega-3s to the diet may prevent diabetic retinopathy.
