New study links lutein with eye health benefits
Lutein, a chemical found in green vegetables, is a member of a family of substances known as carotenoids. Beta-carotene is the most famous nutrient in this class. Like beta-carotene, lutein is an antioxidant that protects our cells against damage caused by dangerous, naturally occurring chemicals known as free radicals.
Recent evidence has found that lutein may play an important role in protecting our eyes and eyesight. It may work in two ways: by acting directly as a kind of natural sunblock, and also by neutralizing free radicals that can damage the eye.
