Spinach and Eggs Can Help Your Vision
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 this week.
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.
"Lutein and zeaxanthin may be considered as useful agents in food or supplement-based interventions designed to reduce the risk of AMD," the researchers wrote in their report, published in the journal Archives of Ophthalmology.
Foods considered good sources of the nutrients include eggs, spinach, kale, turnip greens, collard greens, romaine lettuce, broccoli, zucchini, corn, garden peas and Brussels sprouts.
