A high-glycemic-index diet is a risk factor for macular degeneration.

Age-related macular degeneration (AMD) is the leading cause of vision loss among people age 65 and over. Now, according to a study in the October issue of The American Journal of Clinical Nutrition, a high-glycemic-index diet could play a role in the development of the condition. More than 3,600 participants age 49 and older were examined between 1992 and 1994; 2,335 patients were re-examined after five years; and 1,952 after 10 years. A food-frequency questionnaire was used to collect dietary information at baseline. Over 10 years, 208 of 1,810 people developed early AMD. A higher average dietary glycemic index was associated with an increased 10-year risk of early AMD. People who stuck to a low-glycemic-index diet, which included high-fiber foods and oatmeal, had a reduced risk of developing AMD.
