Spinach, eggs ward off cause of blindness

(Today`s Zaman) Two nutrients found in eggs, spinach and other leafy green vegetables offer some protection against the most common cause of blindness among the elderly, researchers said on Monday.

Age-related macular degeneration affects 1.2 million Americans, mostly after age 65, and the irreversible condition gets gradually worse, robbing victims of the center of their vision. Many people may be susceptible due to genetic factors, while smoking is known to heighten the risk. The two nutrients, lutein and zeaxanthin, are both carotenoids -- compounds that give many fruits and vegetables a yellow color. They help ward off the condition, apparently by allowing the eyes to filter harmful short-wavelength light and by curtailing other damaging effects to the macula, or the center of the eye's retina, the researchers said. "No clear associations with other nutrients were seen, including the vitamins C and E and beta-carotene," according to the researchers, led by John Paul SanGiovanni of the National Eye Institute, one of the National Institutes of Health in Maryland.
