1. The role and function of vitamin A
1. Vitamin A, also known as retinol, from the name we can feel its importance to eye vision.
2. Strictly speaking, in the human body, vitamin A includes three forms: retinol, retinaldehyde and retinoic acid.
3. Vitamin A helps light energy to be converted into optic nerve impulses on the retina, thereby realizing nerve conduction to vision. This function of maintaining normal vision is based on retinoids. The form of aldehyde acts. During this conduction process, part of the retinaldehyde will be oxidized into retinoic acid. To maintain vision, retinal needs to be constantly replenished, and this source is retinol stored in the liver and fat tissue. Retinol and retinaldehyde can be converted into each other.
4. In addition to maintaining vision, vitamin A is also involved in protein synthesis, cell differentiation, sperm development, bone formation, etc.
5. Night blindness and dry eye are the main manifestations of vitamin A deficiency. In addition, epidermal keratosis, that is, dry, rough, scaly skin, and susceptibility to infectious diseases are also manifestations of vitamin A deficiency, because vitamin A deficiency can lead to abnormalities in epidermal cells and mucosal cells.
6. In food, retinol only exists in animal foods, such as animal liver, kidney, dairy products, cod liver oil, and egg yolk. In plants, they exist as carotenoids known as vitamin A precursors. Some carotenoids can be converted into vitamin A in the body, among which β-carotene has the highest conversion rate.
7. Beta-carotene is essentially a pigment, which is found in yellow, orange andThe content is higher in green fruits and vegetables, and the darker the color, the higher the content. Green fruits and vegetables contain a lot of chlorophyll, so they cover up the yellow color.
8. Vitamin A and carotene are fat-soluble and insoluble in water. Therefore, the vitamin A in skimmed milk has basically been removed. In addition, some people think that to enhance the absorption of carotene, a lot of oil must be used for cooking. In fact, this is not necessary. After the vegetable is heated, the cell wall softens, and only a small amount of oil is needed to ensure the absorption of carotene. But if it is raw food, more fat is needed to ensure absorption.
9. Finally, it needs to be emphasized that vitamin A is not easily excreted from the body, so excessive intake may cause toxicity. However, excessive intake of normal meals will not occur. It will only occur if a large amount of liver, cod liver oil or vitamin A supplements are consumed. Excessive intake of vitamin A can lead to abnormal bone growth and, for pregnant women, can increase the rate of fetal malformations.
10. If you eat a lot of foods containing carotene, it will not be a big problem. At most, your skin will turn yellow. After stopping eating, the yellow color of the skin will fade. However, carotene supplements should not be taken in large amounts, otherwise they may be harmful.
