A new study suggests that changing from a high to low glycemic diet could reduce the risk of developing age-related macular degeneration (AMD).
The study, published in the Proceedings of the National Academy of Sciences, involved observing 19 mice fed on a low-glycemic diet and 40 mice on a high-glycemic diet.
In both groups, carbohydrates made up 45% of the diet. After six months, the high-glycemic mice either remained on the same diet or switched to a diet containing starches found in whole grains.
Researchers found that the high-glycemic mice began to develop many AMD features, while mice on a low-glycemic diet did not. When some of the mice switched to a diet with starches found in whole grains, the damage to the retina stopped.
