Diabetic retinopathy is a serious complication of type 2 diabetes: it occurs when an excess of sugar in the blood (chronic hyperglycemia) leads to the rupturing and then bursting of the small blood vessels (capillaries) of the retina. Diabetic retinopathy affects approximately 50% of patients and is the leading cause of blindness after age 65.

Researchers at the University of Oklahoma (in the United States) may have just discovered a way to prevent vision problems, the first signs of diabetic retinopathy. In their work (published in the specialist magazine The American Journal of Pathology), scientists say vitamin A supplementation would help preserve the vision of people with diabetes.

To reach this conclusion, the American researchers worked with 3 groups of mice: the first group (composed of diabetic mice) received an injection of retinaldehyde – one of the 3 forms of vitamin A. The second group (also composed of diabetic mice) received a placebo. The third group (non-diseased mice) was a “control group”.

Verdict? The mice in the first group (who received vitamin A supplementation) had a better view than the mice in group 2. “Our hypothesis is that diabetes leads to disturbances in the metabolism of vitamin A, which promotes the visual disturbances that herald diabetic retinopathythe researchers explain.

If, of course, additional studies are needed to confirm these results, this work underscores the importance of vitamin A in the diet. The best sources of Vitamin A are: beef liver, sweet potato, spinach, carrots, mango, pumpkin, dandelion, apricot and melon.

Without forgetting the cod liver oil: 1 teaspoon. until s. (15 ml) of this unsavory food provides 15,000 international units (IU) of vitamin A, while the recommended daily intake is approximately 2,400 IU for women!
