Vitamin A includes a group of compounds that affect vision, bone growth, reproduction, cell division, immunity, and
healthy surface linings of the respiratory tract and mucous membranes. There are two categories of vitamin A, depending on whether the food source is an animal or a plant. Vitamin A found in animal foods is called preformed vitamin A and is absorbed as retinol. Sources include liver, whole milk, and some fortified food products. In the body retinol can be made into retinal and retinoic acid (other active forms of vitamin A).
Plant sources of vitamin A provide the provitamin A, called carotenoids. They can be made into retinol in the body and then into the other active forms of vitamin A. In the United States approximately 26% to 34% of vitamin A consumed is in the form of provitamin A carotenoids. Common provitamin A carotenoids which give plants their color, and are b-carotene, a-carotene, and b-cryptoxanthin. Among these, b-carotene is most efficiently made into retinol. The darker the color of a fruit or vegetable, the greater is its carotenoid content. Vitamin A deficiency rarely occurs in the United States.
Vitamin A deficiency is more common in developing countries, where access to sufficient animal and beta-carotene containing plant sources is limited. Vitamin A deficiency is a leading cause of preventable blindness in children. Children with measles or diarrhea can significantly benefit from increased vitamin A. Fat malabsorption can result in diarrhea and prevent normal absorption of vitamin A; this may result in vitamin A deficiency in celiac disease, Crohn’s disease, and pancreatic disorders. The best absorbed form of vitamin A is in the oil form such as in cod liver oil.
