Definition: Phytochemicals found in red, orange or yellow fruits and vegetables. Carotenoids are precursors to vitamin A, which means your body can transform some of them into vitamin A.
Beta-carotene is the carotenoid that is most easily converted, but alpha-carotene and beta-cryptoxanthin can also be converted to Vitamin A, just in smaller amounts.
Other carotenoids cannot be turned into vitamin A. However, they may trigger antioxidant reactions in your body. These include lycopene, lutein and zeaxanthin.
