Fruits and vegetables with bright red, orange and yellow colors often contain a good amount of betacarotene. Betacarotene is an antioxidant that turns into vitamin A in the body. If you do not consume enough betacarotene, you may become deficient in vitamin A, which can lead to abnormal bone development, reproductive disorders and, in severe cases, death. Betacarotene also supports healthy eyes and may prevent diseases like macular degeneration. One cup of fresh nectarines supplies 214 mcg of betacarotene.
