Protect Your Vision with Nutrient-Rich, Low-GI Foods

An analysis of data from the Age-Related Eye Disease Study (AREDS) revealed that study participants whose diets were high in certain nutrients and foods with a low glycemic index (GI) had the lowest risks of age-related macular degeneration (AMD). AMD, which initially affects central vision, may result in severe vision impairment and even blindness. In the study, participants? food intake was analyzed to determine the amounts of vitamins C and E, zinc, lutein, zeaxanthin, omega-3 fatty acids, and low-GI foods they were consuming. Foods with a lower GI include vegetables, fruits, and whole grains, while many “white” foods (e.g., white bread, white rice, and white flour) are higher on the GI scale. Foods that support eye health include citrus, vegetable oils, nuts, whole grains, dark green leafy vegetables, and cold-water fish.
