library / Lutein

Lutein is a yellow-green pigment and part of the carotenoid family of phytonutrients.

Found in the retina, it serves as an accessory light-gathering pigment and helps to to protect against ultra-violet radiation. Because of this, it is most well known for its ability to reduce the risk of age-related macular degeneration (AMD) and cataracts.

Recent research shows it may also help to protect against a number of cancers and, as an antioxidant, help to reduce the risk of heart disease.

The most bioavaiable source of lutein is egg yolks. It is also found in leafy green vegetables. Like its other carotenoid cousins, lutein is lipid (or fat) soluble and best used by the body when it is cooked and eaten with a small amount of healthy fat.
