Healthy food can’t prevent aging of the eyes. But certain nutrients can, it seems, slow deterioration and the progression of certain diseases. Studies have shown that eating foods rich in vitamins C and E, or taking supplements of those vitamins and beta-carotene-all antioxidants-may slow the development of cataracts. Those same nutrients, plus the minerals zinc and copper, impede the development of macular degeneration.
Scientists have found some evidence that supplements containing lutein and zeaxanthin both found in the lens of the eye may retard cataracts. And studies suggest that eating kale, mustard greens, collard greens, and spinach (all high in lutein and zeaxanthin) may reduce the risk of developing advanced macular degeneration.
People who eat fish, especially ones rich in omega-3 fatty acids, appear to a lower risk of macular degeneration.
