What is vitamin A?


In the human organism, vitamin A is primarily involved in cell growth and the functioning of the immune system. It is of fundamental importance for the health of the skin and mucous membranes. For the function of the visual process, the retinal is crucial, in which vitamin A can be converted. One of the first signs of a vitamin A deficiency can be night blindness, which makes it difficult to see at dusk.
If there is a pronounced deficiency, blindness, reproductive disorders or even disorders of the immune system can occur. The German Society for Nutrition (DGE) recommends a daily requirement of 1.0 milligrams of retinol equivalent per day for men aged 19 and over, and 0.8 milligrams per day for women aged 19 and over. Can the daily requirement simply be covered by food? A large amount is found in liver and in foods containing liver. Other animal foods, such as eggs or meat, contain comparatively small amounts of vitamin A. The human organism primarily obtains provitamins (beta-carotene) from plant foods as precursors of the vitamin. These are converted into vitamin A by the liver, lungs and small intestine after absorption in the body.
Carrots, kale and spinach are particularly recommended - these foods are among the most provitamin-rich plant foods. It is recommended never to eat a carrot salad without a source of fat. Always add a dash of high-quality oil to a tasty carrot salad so that more beta-carotene can be absorbed in the intestine. It is also recommended to consume a vegetable juice, as more provitamins are released during juicing, which is due to the destruction of the cells of the food.
