Greens

Leafy dark green vegetables, such as Savoy cabbage, kale, and spring greens, are good sources of two carotenoids which have been shown to help prevent age-related macular degeneration and cataracts. Greens are also a good source of easily absorbed calcium to help maintain strong bones, and are rich in potassium, which helps protect against calcium loss. In addition, they're a good source of vitamins C and E.
