What are the functions and functions of vitamin C?
The main functions and functions of vitamin C are:
(1) Improve human immunity.
White blood cells in the human body are rich in vitamin C. When the vitamin C in white blood cells decreases sharply, the body is easily infected by bacteria.
Therefore, maintaining sufficient vitamin C can enhance the chemotaxis and deformability of neutrophils, improve the bactericidal ability, promote the generation of lymphocytes, improve the body's ability to identify and kill foreign and malignant cells, and inhibit the invasion of viruses.
(2) It can make protein cells pile up with each other, promote the metabolism of tyrosine and tryptophan in amino acids, help to make collagen, prevent aging and prolong life.
(3) promoting the biosynthesis of collagen, thus accelerating wound healing, helping to treat trauma and burns, and accelerating postoperative recovery.
(4) Improve the utilization rate of iron, calcium and folic acid, and treat anemia.
Vitamin C can reduce the hard-to-absorb trivalent iron to the easy-to-absorb divalent iron, promote the absorption of iron, improve the utilization rate of iron in the liver, and treat iron deficiency anemia.
(5) can detoxify.
Some heavy metal ions, such as lead, mercury, cadmium, arsenic, etc., are toxic to the body, and supplementing a large amount of vitamin C can reduce their toxicity.
(6) Improving the metabolism of fat and lipid, especially cholesterol, is helpful to reduce cholesterol in blood, reduce the occurrence of venous thrombosis and prevent cardiovascular diseases.
(7) It can promote hydroxylation and detoxification of organic substances or poisons, increase the activity of enzymes, and enhance the efficacy of drugs for treating urinary tract infections.
(8) Prevention of cancer.
Vitamin C can resist the damage of free radicals to cells, prevent cell variation and the formation of strong carcinogen nitrosamines, and help prevent the spread of cancer cells.
(9) Enhance skin elasticity and prevent pigmentation.
Vitamin C is a strong antioxidant, which itself is oxidized to reduce oxidized glutathione to reduced glutathione, thus playing an antioxidant role, ensuring the integrity and normal metabolism of cells and enhancing skin elasticity.
Because of its powerful function, vitamin C has always been the most well-known nutrient among all vitamins.
It is not only the favorite of women who love beauty, but also the savior of people with low resistance.
However, because vitamin C is very sensitive to light, heat and oxygen, plus it is a water-soluble vitamin, the best way to supplement it is to eat it immediately after buying fruits and vegetables. If it needs to be preserved, it is best to pack it in porous plastic bags or paper bags and put it in the shade or under the refrigerator.
Of course, vitamin C has many other functions, such as detoxification and promoting the absorption of folic acid and iron.
However, this is not enough to really get healthy. We need vitamin c supplements. ..
The best way to get vitamin C is to supplement it from food.
Because if you take vitamin C supplements, 1 ~ 2 hours will be completely absorbed and excreted, while vitamin C taken from food will stay in the body for a longer time because of its slow absorption and utilization.
If you want to supplement vitamin C, you should eat more fresh fruits and vegetables, such as jujube, fresh jujube, strawberry, kumquat, garlic, asparagus, sweet pepper, spinach, radish leaves, tomatoes, Chinese cabbage, potatoes, peas, potted head vegetables, shepherd's purse and so on.
Don't forget to take vitamin C and other precautions every day:
(1) 0 ~ 1 year-old infants, vitamin C should be supplemented with 30mg daily.
(2) Children aged1~10 should be supplemented with vitamin 35 ~ 50mg every day.
(3) 1 1 ~ 18-year-old teenagers should take 50 ~ 60mg of vitamins every day.
(4) Adults should take 60 mg of vitamin C every day.
(5) Pregnant women should take 80 mg of vitamin C every day.
(6) The daily vitamin C supplement for lactating women should be 100 mg.
(7) Patients with urethral calculi should avoid taking vitamin C. ..
(8) Fruity vitamin C should not be eaten as sugar.
