Lutein and Zeaxanthin

Lutein and Zeaxanthin

Lutein and zeaxanthin are antioxidant compounds known as xanthophylls, which are the yellow pigments found in plants. The pigments are also found at concentrated levels in the lenses of the eyes. Lutein and zeaxanthin may help prevent cataracts and reduce the need for cataract surgery, but it is unclear how much is required daily to protect eye health. The best sources of lutein and zeaxanthin include green leafy plants such as kale, spinach, collards and turnip greens. Lutein and zeaxanthin are also found in green peas, corn, broccoli, romaine lettuce, carrots, green beans and eggs. People should aim for five to nine servings of vegetables and fruits daily, according to All About Vision. Five servings of well-chosen fruits and vegetables can provide 5 to 6 mg of lutein and zeaxanthin. Consuming 6 mg of lutein and zeaxanthin daily is associated with health benefits, states the American Optometric Association.
