We all know the efficacy and function of taking vitamin C, and the efficacy and function of vitamins that we often eat in our lives. Many vitamins can be used as medicine, and the same vitamin may not be suitable for everyone. People with cold constitution should eat as little as possible. Taking vitamin C is very important for health care.
The efficacy and role of taking vitamin C What are the benefits of taking vitamin C?
1, protein synthesis: Vitamin C can participate in the synthesis of protein, and if it is deficient in vivo, it will cause cell connection disorder.
Collagen accounts for 1/3 of the protein of the body, which generates connective tissue and constitutes the bones of the body. Such as bones, blood vessels and ligaments. , determine the elasticity of the skin, protect the brain, and contribute to the healing of human trauma.
2, scurvy: the strength of blood vessel wall has a lot to do with VC. Microvessel is the smallest of all blood vessels, and its wall may be only one cell thick. Its strength and elasticity are determined by collagen, which is responsible for connecting cells and has the function of cement. When VC is insufficient in the body, microvessels are easy to rupture and blood flows to adjacent tissues.
When this happens on the skin surface, it will produce congestion and cyanosis; When it happens in the body, it can cause pain and joint swelling. In severe cases, bleeding of stomach, intestine, nose, kidney and periosteum may occur, and even death may occur.
3. Gum atrophy and bleeding: A healthy gum tightly wraps every tooth. Gingiva is soft tissue, which is prone to atrophy and bleeding when lacking protein, calcium and VC. Vitamin c is slightly acidic. As a micronutrient, it is ingested into the body. After being dissolved and digested in the body, its acidity and alkalinity have little effect on the human body, so it is not necessary to pay too much attention to its acidity and alkalinity. Vitamin C helps to consolidate cell tissue, help to synthesize collagen, strengthen bones and teeth, and prevent gum bleeding. Long-term use is harmless and beneficial to teeth and gums.
4, arteriosclerosis: vitamin C can also alleviate and prevent arteriosclerosis, because it can promote the excretion of cholesterol.
5, chemicals: vitamin C can also play the role of antioxidants, such as vitamin A, vitamin E and so on. It can prevent some harm of free radicals to human body.
6. Anemia: It can reduce trivalent iron that is difficult to be absorbed and utilized to ferrous iron, promote the absorption of iron in intestine, improve the utilization rate of iron in liver, and help to treat iron deficiency anemia.
7. Prevent cancer cells from spreading: Rich collagen helps prevent cancer cells from spreading; The antioxidant effect of VC can resist the damage of free radicals to cells and prevent cell variation; Prevent nitrite and secondary amine from forming strong carcinogen nitrosamine. Someone once dissected a patient who died of cancer and found that the VC content in the patient was almost zero.
8. Metabolism: In human life activities, glutathione and enzymes are very important to ensure cell integrity and normal metabolism. Because most mammals can synthesize vitamin C through the liver, there is no problem of deficiency. However, a few animals, such as humans, primates and groundhogs, cannot synthesize themselves and must be ingested through food and drugs.
9, human immunity: white blood cells are rich in VC, when the human body is infected, the VC in white blood cells decreases sharply. VC can enhance the chemotaxis and deformability of neutrophils and improve their bactericidal ability.
Precautions for taking vitamin c
1, can't be eaten with pig liver.
Vitamin C is easily oxidized to lose its activity, especially copper and iron ions, which will accelerate its oxidation rate by thousands of times. But pig liver is rich in copper and iron ions. Therefore, at the same time, vitamin C and pig liver will make vitamin C produce other substances and fail.
2. Don't eat with eggs.
Milk and other foods rich in vitamin B2 are put into food and eaten simultaneously. Vitamin B2 is redox, and its oxidation is stronger than reduction. At the same time, vitamin C will not only fail, but also affect the function of vitamin B2 in the body, which can be said to be "lose-lose".
Don't eat a lot of vegetables while taking vitamin C.
These vegetables contain vitamin C decomposing enzymes, which can promote the decomposition of vitamin C, so they have no effect.
4. Use less vitamin C when smoking.
Although the vitamin C content of smokers is lower than that of non-smokers, they need vitamin C supplementation. However, research shows that smoking will change the nature of vitamin C in saliva, making it a substance harmful to human body.
Foods rich in vitamin c
1, orange
Most people know that the content of vitamin C in oranges is extremely high, and its taste is also recognized by people. Besides, according to a recent survey, the smell of oranges can relieve people's anxiety and make them feel comfortable.
2, persimmon pepper
Persimmon pepper is rich in vitamin C, which is more than twice that of ordinary green pepper. Regular consumption can effectively increase the content of vitamin C in the body.
Step 3: strawberries
For some people, strawberries are just an ideal sweet and sour snack. In fact, strawberries are also a good source of cellulose, magnesium and vitamin C.
4. papaya
Papaya contains a lot of vitamin C, which sounds incredible. Papaya is rich in vitamins A, C, K and cellulose. If you eat a few slices of papaya or a small dish of papaya salad every day, you can get the vitamin C content that the human body needs every day.
Efficacy and function of taking vitamin C Can I take 2 vitamin C every day?
1, can I take vitamin C every day?
Generally speaking, vitamin C tablets are taken orally. When used to supplement vitamin C, adults take 50-100 mg daily; For the treatment of vitamin C deficiency, adults should take 100-200mg once, three times a day, and children should take 100-300mg once a day for at least 2 weeks. In addition, some health vitamin C tablets (taking Yangshengtang natural vitamin C chewable tablets as an example) are recommended to be taken twice. 1 tablet should be taken after breakfast and lunch, because vitamin C is a water-soluble vitamin and needs to be supplemented repeatedly at intervals of 3-4 hours.
Previous experiments have shown that calcium oxalate stones and kidney calculi may appear in the urinary tract after one week of oral administration of vitamin C4.
2. Pharmacological effects of vitamin C tablets
The drug is involved in the formation of antibodies and collagen in vivo, tissue repair (including some redox effects), metabolism of phenylalanine, tyrosine and folic acid, utilization of iron and carbohydrates, synthesis of fat and protein, maintenance of immune function, hydroxylation of serotonin, maintenance of vascular integrity and promotion of non-heme iron absorption.
Excessive vitamin c is harmful.
Previously, it was thought that vitamin C had little toxicity, even if it was taken orally in excess, it would only cause slight nausea, vomiting, diarrhea and so on. However, in recent years, clinical observation and animal experiments have proved that long-term overdose of vitamin C will lead to a series of adverse reactions. Referring to a variety of information at home and abroad, the summary is as follows: The University of California reported that people who want to increase their resistance to colds and take vitamin C for a long time have a lower vitamin C content. This is because taking a large dose changes the regulation mechanism of vitamin C in the body and accelerates the decomposition and excretion of vitamin C. Once the drug is stopped, it can lead to withdrawal reaction and early scurvy symptoms, such as swollen gums, bleeding and loose teeth. Using large doses of vitamin C in growing children will make children vulnerable to bone diseases in the future.
The role of vitamin c
1 and the therapeutic effect of vitamin C to treat trauma, burn and gingival bleeding; Enhance the efficacy of drugs used to treat urinary tract infections; Accelerate postoperative recovery; Helps lower cholesterol in the blood.
2. The role of vitamin C in improving immunity. White blood cells are rich in VC, and when the body is infected, the VC in white blood cells decreases sharply. VC can enhance the chemotaxis and deformability of neutrophils and improve their bactericidal ability. Promote the generation of lymphocytes and improve the body's ability to identify and kill foreign cells and malignant cells. Participate in the synthesis of immunoglobulin. Prevent virus and bacterial infections and enhance the function of immune system; Has anticancer effect; Reduce the occurrence of venous thrombosis; Can be used for treating common cold and has preventive effect.
3. The whitening effect of vitamin C. Vitamin C is added to many whitening products, which is considered to have great whitening effect because it can help the skin resist ultraviolet rays and avoid black spots and freckles.
