2. Promote the immune system
Why do you need to supplement vitamin C (discuss the importance of vitamin C and its supplement methods)
1. It has antioxidant effect.
Vitamin C can promote the normal function of the immune system and help the body resist diseases and infections. It can help to produce white blood cells and enhance their functions, thus improving the body's immunity.
1. Food
The Importance of Vitamin C Vitamin C is very important for all animals, including humans, because it is essential for the production of collagen. Vitamin C is also important because it helps to protect fat-soluble vitamins A and E and fatty acids from oxidation. Prevention and treatment of scurvy with vitamin C is beneficial to the treatment of iron deficiency anemia.
Collagen is the most common substance in the body because it is the most abundant fiber in connective tissue. Connective tissue shapes our body shape and supports our organs. In order to let you know the importance of collagen, here are five kinds of collagen and their uses in the body.
1 type-connective tissue of skin, bones, teeth, tendons, ligaments, fascia and organ capsules.
Type 2-cartilage
Type 3-Connective tissue of our organs (liver, spleen, kidney, etc.). )
Type 4,5-The separation layer between epithelial cells and endothelial cells and the separation layer between bone or smooth muscle cells (basal layer), glomeruli, lens capsule and Schwann cells and glial cells of nervous system.
As you can see, collagen is everywhere in the body, and vitamin C plays an important role in the formation of collagen. So, how does vitamin C participate in collagen synthesis?
When collagen is produced, a series of complex events will occur, some of which occur inside the cell and some of which occur outside the cell. Vitamin C is very active in cells, where it is hydroxylated (adding hydrogen and oxygen) into two amino acids: proline and lysine. This helps to form a precursor molecule called procollagen, which is later packaged in the cell coat and modified into collagen. Without vitamin C, the formation of collagen will be destroyed, leading to various problems all over the body.
What will happen to vitamin c overdose? Pay attention to vitamin c intake? In a word, vitamin C is an important nutrient, but too much intake will have adverse effects on the human body. Therefore, in daily life, it is necessary to reasonably control the intake of vitamin C and avoid excessive intake.
Excessive intake of vitamin C can lead to indigestion symptoms such as diarrhea, nausea and vomiting. This is because vitamin C has osmotic effect. Excessive intake will increase the osmotic pressure in the intestine and make water flow from the intestine to the intestinal cavity, leading to symptoms such as diarrhea.
Vitamin C, also known as ascorbic acid, is one of the essential nutrients for human body. It has many functions, such as anti-oxidation, promoting iron absorption, enhancing immunity and promoting collagen production. However, if you take too much vitamin C, it will have adverse effects on the human body.
2. Insufficient absorption of copper
The recommended intake of vitamin C varies with age, sex and physiological status. According to the dietary guidelines of China residents, the daily intake of adult males is 100 mg, and that of females is 85 mg. The demand of pregnant women and lactating women will be slightly higher. At the same time, the demand for vitamin C by smokers and alcoholics will also increase.
