Tip of the Day

Lutein is a yellow plant pigment in the carotenoid family. Yellow and orange vegetables have only trace amounts of lutein; large amounts are found in green vegetables like broccoli, collard greens, kale, and spinach. Lutein is also available as a supplement made from marigold flowers. Your body uses lutein to make macular pigment (MP) in your retina, and this substance protects your eyes from the sun's harmful blue light rays, which can damage your retina and lead to AMD. MP shields your eyes like a pair of sunglasses, explains Richard Bone, Ph.D., a lutein researcher at Florida International University in Miami. Lutein, an antioxidant, also fights the free radicals that contribute to eye damage. (Source: Natural Health magazine, Supplement Flash; online at www.naturalhealthmag.com.)
