Carrots are the fleshy roots of plants in the Umbelliferae family, containing a large amount of vitamin A and dietary fiber. Carotenoids can be converted into vitamin A in the body, which is helpful for maintaining skin and mucosal health. Carrots are suitable for raw consumption or stewing, and when combined with oil, they can increase the absorption rate of carotenoids.
