High glycemic diets may increase the risk of age-related macular degeneration

This is big, I think:

In a new study published in the American Journal of Clinical Nutrition, researchers tested the theory that dietary glycemic index (GI), which has been associated with the risk of diabetes and CVD [cardiovascular disease], may also increase the risk and severity of AMD [age-related macular degeneration] in elderly populations . . . Compared with the eyes in those with the lowest GI diets, eyes in the high GI subjects had significantly higher risk of AMD progression and severity. There was a 49% increase in the risk of advanced AMD for persons who ate a diet higher than average in GI. Researchers noted that the results indicated that 20% of all AMD cases in the study would have been eliminated if the participants consumed diets with a GI below the average.
