High antioxidant intake reduces risk of AMD

High dietary intake of antioxidants is associated with a lower risk for early age-related macular degeneration (AMD) in genetically predisposed individuals, according to the Archives of Ophthalmology.Researchers assessed the intake of antioxidants, zinc, and omega-3 fatty acids in daily foods, diagnosed the onset of early AMD during a lengthy follow-up, and investigated the risk-reducing effect of these nutrients in the various genotypes in 2167 individuals 55 years or older.

"High dietary intake of nutrients with antioxidant properties reduces the risk of early AMD in those at high genetic risk," the study authors write. "Therefore, clinicians should provide dietary advice to young susceptible individuals to postpone or prevent the vision-disabling consequences of AMD. Fortified cereals, meats, dairy products, nuts, and seeds are a good source of zinc; dark-green leafy vegetables such as spinach and kale and orange vegetables including carrots and pumpkin are rich in β-carotene and lutein/zeaxanthin; and oily fish such as herring, salmon, sardines, trout, and tuna provide EPA/DHA," the study authors conclude.
