The carrot is usually orange in colour, though purple, red, white, and yellow varieties also exist. This root vegetable gets its characteristic and bright orange colour from beta-carotene. This pigment is so strong in fact, that massive overconsumption of carrots can cause carotenosis, a benign condition in which the skin turns orange! However, the health benefits of carrots far outweigh this insignificant risk. Human bile salts metabolise beta-carotene into vitamin A, which supports healthy eyes and enhances vision. Carrots are also rich in dietary fiber, antioxidants, and minerals. Ethnomedically, the roots are used to treat digestive problems.
