Beta carotene health guide lexicon

Beta-caroteneAt Beta-carotene It is a precursor of vitamin A (retinol), which is why it is also called provitamin A. It belongs to the natural colorants found in plants, the carotenoids, and is ingested with food. Since beta-carotene is bound to certain fats within foods, the utilization of the substance in the human body takes place with the involvement of fat metabolism.

How beta-carotene works? In the body, beta-carotene is produced with the help of bile acid. broken down by various enzymes. Via the intestinal mucosa of the small intestine, part of the decomposed beta-carotene is converted into vitamin A. The remaining components are stored in fatty tie. Vitamin A is transported from the small intestine to the liver, where it is stored.

If the body has a need for vitamin A, it is released again by the liver. If, on the other hand, enough vitamin A is already present in the body, the conversion of beta-carotene into vitamin A is reduced. If too much beta-carotene has been ingested, this is also stored by the body in fatty tie.

Significance for health

Beta-carotene is particularly important as a free radical scavenger, which is why it is believed to have a preventive effect against cancer. In addition, it is involved in the metabolism of the skin and mucous membranes, among other things. Since the cells of the eye are also affected, it also influences vision. In addition, there is a participation of beta-carotene in the sperm-. placental development as well as in testosterone production. In children, it also affects growth and bone formation.

The daily requirement of beta-carotene can basically be taken up with food. A deficiency usually only occurs in people with an increased need. This includes especially sick people, women during pregnancy and lactation, smokers and alcoholics.

A permanent undersupply of beta-carotene and thus of vitamin A can lead, among other things, to a deterioration of vision with night blindness and sensitivity to light. Dry skin due to a disorder of the skin metabolism can also be a consequence.

In contrast, an over-supply of beta-carotene is not possible. If the body signals a sufficient amount of vitamin A, the conversion of beta-carotene is stopped and excess beta-carotene is stored in fatty tie. However, too high an intake can temporarily lead to a harmless yellowing of the skin. However, it is warned against an overdose of beta-carotene by taking vitamin tablets, as this can have a carcinogenic effect.

In general, the beta-carotene content of vegetables is higher than that of fruits, but it also depends on the degree of ripeness and the season of harvesting. In addition, light, unrefrigerated storage of food and long cooking times can lead to a reduction in the content of beta-carotene.

In order for the body to better absorb beta-carotene from food, food should be steamed or blanched. In addition, it is recommended to take fat at the same time as the meal, as beta-carotene is fat-soluble. This article was written in accordance with the current medical literature.
