Chemical names: Retinol, retinal, and four carotenoids, including beta carotene.Important for vision, reproductive function, and normal cell reproduction. Beta-carotene, a precursor to Vitamin A, helps to fight disease-causing free radicals. Vitamin A is found in milk products, organ meats, and fish oils. Beta-carotene is found in colorful vegetables, such as carrots, broccoli, spinach, and sweet potatoes.
Vitamin A promotes healthy vision and skin, and it also supports bone and tooth growth. In addition, vitamin A helps your immune system and is important in the reproductive process. Finally, vitamin A enables your heart, kidneys, lungs, and other organs to work properly.
Vitamin A is a fat-soluble vitamin that is naturally present in many foods. Vitamin A is important for normal vision, the immune system, and reproduction. Vitamin A also helps the heart, lungs, kidneys, and other organs work properly.
There are two different types of vitamin A. The first type, preformed vitamin A, is found in meat, poultry, fish, and dairy products. The second type, pro-vitamin A, is found in fruits, vegetables, and other plant-based products. The most common type of pro-vitamin A in foods and dietary supplements is beta-carotene.
Your Need It:
Although vitamin A deficiency is rare in All over the world, it is still important to have enough of it in your diet. There are certain groups of people that are at risk of having low vitamin A levels, including premature infants and people with cystic fibrosis. Vitamin A deficiency can lead to an eye condition called xerophthalmia, which can lead to blindness.
The amount of vitamin A you need depends on your age and reproductive status. Recommended intakes for vitamin A for people aged 14 years and older range between 700 and 900 micro-grams (mcg) of retinol activity equivalents (RAE) per day. Recommended intakes for women who are nursing range between 1,200 and 1,300 RAE. Lower values are recommended for infants and children younger than 14.
However, the vitamin A content of foods and dietary supplements is given on product labels in international units (IU), not mcg RAE. Converting between IU and mcg RAE is not easy. A varied diet with 900 mcg RAE of vitamin A, for example, provides between 3,000 and 36,000 IU of vitamin A depending on the foods consumed.
For adults and children aged 4 years and older, the U.S. Food and Drug Administration has established a vitamin A Daily Value (DV) of 5,000 IU from a varied diet of both plant and animal foods. DVs are not recommended intakes; they don’t vary by age and sex, for example. But trying to reach 100% of the DV each day, on average, is useful to help you get enough vitamin A.
Vitamin A can be found in both plant and animal sources. Some good foods to eat to get vitamin A are milk, cheese, and butter. Sources that are lower in fat are carrots, pumpkins, and apricots.
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:
- Beef liver and other organ meats (but these foods are also high in cholesterol, so limit the amount you eat).
- Some types of fish, such as salmon.
- Green leafy vegetables and other green, orange, and yellow vegetables, such as broccoli, carrots, and squash.
- Fruits, including cantaloupe, apricots, and mangoes.
- Dairy products, which are among the major sources of vitamin A for Americans.
- Fortified breakfast cereals.
