If you have diabetes eating fish may save your sight

Regular intake of long-chain omega-3 polyunsaturated fatty acids obtained from oily fish was associated with a reduced risk of sight-threatening diabetic retinopathy in middle-aged and older patients with type 2 diabetes, according to a study conducted in Spain.

The study's finding that consumption of at least 500 mg/d of dietary long-chain omega-3 polyunsaturated fatty acids (LC3PUFAs) decreased the risk of diabetic retinopathy (DR) in patients with diabetes corroborates experimental models and the current theory of DR pathogenesis, according to the report.

The prospective investigation included 3,482 patients with a mean age of 67 years diagnosed with type 2 diabetes who had participated in the PREDIMED study, a randomized clinical trial that tested Mediterranean diets supplemented with extra virgin olive oil or nuts vs. a control diet for primary cardiovascular prevention.

Among the 3,482 patients, 2,611 (75%) consumed the recommended amount of at least 500 mg/d of LC3PUFA, which could be achieved with two servings of oily fish per week.
