Your mom probably told you to eat your carrots, now new research finds there's another orange food that's good for the eyes - an orange! The study finds Vitamin C may help prevent the early development of cataracts. Researchers in Boston followed nearly 500 nurses. Those who got daily doses of at least 360 milligrams of Vitamin C for at least ten years had nearly half the risk of developing cataracts. Researchers add the risk was also lower in non-smokers and in women who had high intakes of folic acid. Cataracts are so common, nearly half the population over 75 will develop a cataract, which clouds the vision. But this study emphasizes the role nutrition can play in cataract prevention. The study is in the American Journal of Clinical Nutrition.
