Vitamin A is found in carrots, sweet potatoes, mangos, kale, squash, apricots, and cantaloupe.
Beta-carotene is a precursor for vitamin A. The body needs to convert it to retinol or vitamin A for use. Beta-carotene is found naturally in mostly orange and dark green plant foods, such as carrots, sweet potatoes, mangos, and kale. Two of the most common sources are retinol and beta-carotene. Retinol is sometimes called “true” vitamin A because it is nearly ready for the body to use. Retinol is found in such animal foods as liver, eggs, and fatty fish. Vitamin A is found naturally in many foods and is added to some foods, such as milk and cereal. You can get recommended amounts of vitamin A by eating a variety of foods, including the following: 1  Beef liver and other organ meats (but these foods are also high in cholesterol, so limit the amount you eat). 1 Green leafy vegetables and other green, orange, and yellow vegetables, such as broccoli, carrots, and squash. 2  Fruits, including cantaloupe, apricots, and mangos. 3  Dairy products, which are among the major sources of vitamin A for Americans. 4  Fortified breakfast cereals. Water-soluble vitamins are found in a wide range of foods, including fruit, vegetables, potatoes, grains, milk and dairy foods. Unlike fat-soluble vitamins, they can be destroyed by heat or being exposed to the air. They can also be lost in water used for cooking.  Two forms of vitamin A are available in the human diet: preformed vitamin A (retinol and its esterified form, retinyl ester) and provitamin A carotenoids [ 1-5 ]. Preformed vitamin A is found in foods from animal sources, including dairy products, fish, and meat (especially liver). By far the most important provitamin A carotenoid is beta-carotene; other provitamin A carotenoids are alpha-carotene and beta-cryptoxanthin. The top food sources of vitamin A in the U.S. diet include dairy products, liver, fish, and fortified cereals; the top sources of provitamin A include carrots, broccoli, cantaloupe, and squash [ 4, 5 ]. The vitamin A found in plants serves different functions than the vitamin A found in animals. The animal sources of vitamin A are liver, whole milk, and fortified foods, and the plant sources include colorful fruits and vegetables like carrots, spinach, kale, and cantaloupe. The recommended dietary allowances (RDA) for vitamin A are listed as international units (IU) of retinol activity equivalents (RAE) In foods of animal origin, the major form of vitamin A is an ester, primarily retinyl palmitate, which is converted to retinol (chemically an alcohol) in the small intestine. The retinol form functions as a storage form of the vitamin, and can be converted to and from its visually active aldehyde form, retinal. Vitamin A is a group of unsaturated nutritional organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, and beta-carotene. Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision. We get vitamin A from a variety of sources. Two of the most common sources are retinol and beta-carotene. Retinol is sometimes called “true” vitamin A because it is nearly ready for the body to use. Retinol is found in such animal foods as liver, eggs, and fatty fish. It also can be found in many fortified foods, such as breakfast cereals, and in dietary supplement 1 Retinol, the form of vitamin A absorbed when eating animal food sources, is a yellow, fat-soluble substance. 2  Since the pure alcohol form is unstable, the vitamin is found in tissues in a form of retinyl ester. 3  It is also commercially produced and administered as esters such as retinyl acetate or palmitate. Vitamin A is a group of unsaturated nutritional organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, and beta-carotene. Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision. Vitamin A can be found in two principal forms in foods 1  : Retinol, the form of vitamin A absorbed when eating animal food sources, is a yellow, fat-soluble substance. 2  Since the pure alcohol form is unstable, the vitamin is found in tissues in a form of retinyl ester. Vitamin A is a group of unsaturated nutritional organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, and beta-carotene. Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision.
