A colored carrot a day could keep the oncologist away.
USDA researchers say carrots colored other than orange contain properties that may prevent certain cancers and heart disease.
Yellow carrots, they say, contain xanthophylls, which keep eyes healthy and prevent lung and other cancers. Red carrots contain lycopene, which is helpful in preventing heart disease and some cancers. Purple carrots possess powerful antioxidants.
Researchers say the different pigments don't appear to affect the flavor of the carrot.
