Q. Are there any foods that can help protect my vision as I get older?
A. Age-related macular degeneration (AMD), a condition characterized by the deterioration of the central retina, or macula, is the leading cause of blindness in people over 50. Studies show that vitamins C and E and zinc, as well as lutein and zeaxanthin—two antioxidants found in yellow and leafy green vegetables and in egg yolks—may help protect against and/or slow the progression of this condition. Furthermore, one Australian study links a high intake of vegetables—any kind—with a lower risk for AMD. While these findings are still preliminary, they underscore the benefits of loading your plate with nutrient-packed foods like vegetables, fruits, nuts—which provide significant amounts of zinc and some vitamin E in a 1-ounce serving—and, yes, even whole eggs. (Studies indicate that whole eggs, if you stick to not more than one per day, can fit into a heart-healthy diet.)
