Vitamin C is a nutrient needed by human body, and insufficient intake can cause scurvy. Vitamin C is used for vitamin C deficiency, acidulous urine and idiopathic methemoglobinemia. However, since the 1990s, it has been reported that vitamin C can also prevent colds, promote wound healing, and reduce cholesterol content. Last year, someone wrote an article saying that taking vitamin C for a long time can make the skin tender, delay the appearance of wrinkles and keep young forever.
However, some medical scientists hold different views on the efficacy of vitamins, thinking that it can not prevent or alleviate colds, promote wound healing, and cannot be used as an oral beauty agent. Another person wrote in a medical journal that if a patient does not have vitamin C deficiency, it is not scientific enough to use vitamin C to treat atherosclerosis and allergies.
In the early 1990s, medical journals reported that it was proved by clinical and animal experiments that taking vitamin C for a long time was harmful to health. Oral administration of1-4g per day can cause rash, diarrhea, gastric acid increase, and increase the contents of oxalic acid and uric acid in urine. It has been reported abroad that taking a large amount of calcium oxalate crystals produced by vitamin C leads to cases of acute renal failure. Sensitive patients will have hyperuricemia due to increased uric acid, resulting in gouty arthritis. If it exceeds 5 grams per day, it can cause hemolysis, and high-dose intravenous injection of vitamin C can cause thrombosis and sudden death. Foreign literature also pointed out that people with heart or renal failure can produce hypernatremia if they take too much vitamin C. Because about12% vitamin C exists in the form of sodium salt in human body. If pregnant women are given large doses of vitamin C, their fetuses will be dependent on vitamin C after birth, and if they are not given large doses of vitamin C, scurvy will occur. It can be seen that vitamin C is not a panacea and must not be abused at will.
Ten wonderful uses of vc films
Magical use of vitamin c
The wonderful use of vitamin C, vitamin C is a common abbreviation for vitamin C. Vitamin C, also called L- ascorbic acid, is a water-soluble vitamin. Let's take a look at the wonderful use of vitamin C.
Wonderful use of vitamin c 1
The efficacy of vitamin c
1, treatment of injuries, burns, bleeding gums.
2. Accelerate the recovery after operation.
3. Help lower cholesterol in the blood.
4, preventing viral and bacterial infections, and having anti-cancer effect; It also enhances the function of immune system and helps to prevent the formation of nitrosamines.
5, can be used as a natural laxative.
6, reduce the occurrence of venous thrombosis.
7, can treat the common cold, and has a preventive effect; Protein cells can be firmly agglomerated with each other, thus prolonging life.
8, increase the absorption of inorganic iron, prevent scurvy.
The role of vitamin c
1, improve human immunity
Vitamin c can enhance the chemotaxis and deformability of neutrophils and improve their bactericidal ability; Promote the generation of lymphocytes, and improve the body's identification and killing of foreign and malignant cells. In addition, vitamin C is involved in the synthesis of immunoglobulin. Promote the production of interferon, interfere with the transcription of virus messenger RNA, inhibit the proliferation of virus, and improve the disease resistance of human body in many ways. Therefore, vitamin C can be properly supplemented in the cold epidemic season to prevent respiratory tract infection and prevent colds.
2. Participate in the synthesis of collagen
The human body is composed of cells, and the connection between cells is connected by intercellular substance, and the key component of intercellular substance is collagen. Collagen accounts for 1/3 of the protein of the body, and participates in the formation of connective tissue, forming the scaffold of the body. Vitamin C plays an important role in the synthesis of collagen. If vitamin C is deficient, it will lead to cell connection disorder, microvessels will easily rupture, and blood will flow to adjacent tissues.
When this happens to the skin, it will produce congestion and cyanosis; When it happens in the body, it causes pain and joint swelling pain; In severe cases, there may be bleeding or even death in the stomach, intestine, nose, kidney and periosteum, so it is called scurvy. The soft tissue of gingiva that wraps every tooth is mainly composed of collagen, which is easy to cause gingival atrophy and bleeding when vitamin C is lacking. The skin will also be rough and lose elasticity due to the reduction of collagen.
3. Antioxidant effect
Free radicals produced by oxidative damage can invade human cells and DNA, leading to cancer; Invasion of blood vessels will accelerate arteriosclerosis; Invasion of the lens of the eye will cause cataracts and so on. Therefore, anti-oxidation is an important health and disease prevention measure. Vitamin C is a powerful antioxidant, which can protect other antioxidants, such as vitamins A and E, from oxidative damage. Can inhibit the generation of lipid peroxidation free radicals, block lipid peroxidation, and prevent free radicals from harming human body.
4. Participate in cholesterol metabolism.
Vitamin C can promote the hydroxylation and excretion of cholesterol, prevent cholesterol from depositing on the inner wall of arteries, and play a role in preventing arteriosclerosis.
5. Promote the absorption of iron, calcium and folic acid.
Iron in food is divided into heme iron and non-heme iron. Heme iron is bivalent iron with high absorption rate. Non-heme iron is trivalent iron, which needs to be converted into divalent iron in the body before it can be absorbed by the human body. Vitamin C can reduce trivalent iron to divalent iron and promote the absorption of iron. Heme iron accounts for 4% in animal meat, and its absorption rate can reach 2%~25%. The non-heme iron in plant food has a low absorption rate of about1%~ 3%. The residents in our country are mainly plant-based foods, so it is very important to eat foods rich in vitamin C to absorb iron, which is also a good way to prevent and treat iron deficiency anemia.
Soluble state of calcium in digestive tract is the basic condition for absorption. Vitamin C can form an acidic medium in the stomach to prevent the formation and precipitation of insoluble calcium complexes and promote the absorption and utilization of calcium.
Vitamin C can reduce folic acid into tetrahydrofolic acid with biological activity, which is beneficial to the absorption and utilization of folic acid and prevents megaloblastic anemia. Therefore, it is best to take vitamin C while taking iron, calcium or folic acid supplements.
6, detoxification
Vitamin C is known as the universal antidote, which can promote the formation of liver glycogen, which plays an important role in liver detoxification. It is a common problem that harmful heavy metals pollute the environment at present, and vitamin C can directly participate in the detoxification process of heavy metals, which can effectively prevent the toxic effects of harmful heavy metals such as lead, cadmium and mercury on human body.
7. Cancer prevention
The antioxidant effect of vitamin C can resist the damage of free radicals to cells and prevent cell variation. Prevent nitrite and secondary amine from forming strong carcinogen nitrosamine. In addition, vitamin C promotes the synthesis of collagen and helps to prevent the spread of cancer cells.
Wonderful use of vitamin c ii
Six functions of vitamin c
1, help treat oral ulcers
Many people often suffer from "oral ulcer", and vitamin C has a good protective effect on the ulcer surface, which is conducive to the healing of oral ulcer.
A study of "New Clinical Use of Vitamin C" published in China Pharmaceutical Journal in 27 years pointed out that vitamin C has a good effect on the treatment of oral ulcer. Because vitamin C is an acidic substance, it can stimulate the parotid gland to secrete a large amount of saliva after being applied locally to the oral cavity, and lysozyme in saliva has strong bactericidal and anti-inflammatory effects. Therefore, vitamin C has a good protective effect on ulcer surface and is beneficial to the healing of oral ulcer. The specific usage is to dip a cotton swab in vitamin C and apply it repeatedly on the ulcer surface, three times a day, usually for two days.
In 2 13, the article "prevention and treatment of simple oral ulcer" published in the medical journal of the primary medical forum also pointed out that the treatment of simple stomatitis is generally given vitamin drugs such as Tuxi powder, Zhuhuang powder or watermelon frost spray, which generally takes about 1 day to cure, or even longer. However, vitamin C tablets and vitamin B complex tablets are mixed in a certain proportion and ground into powder, and then the powder is coated on the surface of the ulcer, which has remarkable effect.
2. Prevent pigmentation
Many people have heard that "drinking lemon water can whiten skin because lemon is rich in vitamin C", but what is the principle?
The above-mentioned research published in "China Pharmaceutical" also pointed out that melanin comes from tyrosine, which is converted into dopa under the action of tyrosine hydroxylase, and dopa continues to be oxidized and finally polymerized into melanin. Vitamin C can inhibit the oxidation of dopa and prevent the formation of melanin. Vitamin C can also reduce scurvy, chronic adrenal hypofunction, post-trauma, post-inflammation and post-acne pigmentation.
3. Alleviate allergies
Some people go to the hospital after they have allergies, and some doctors prescribe some anti-allergic drugs as well as some vitamin C.
This is because vitamin C can relieve allergic diseases. The above-mentioned research published in "China Pharmaceutical" points out that vitamin C has antihistamine and bradykinin effects, and can directly act on bronchial receptors to dilate bronchi. Therefore, vitamin C can be used in medicine to treat allergic diseases such as rheumatic arthritis, asthma and urticaria.
4, relieve hand dry peeling
In autumn and winter, many people will have the problem of dry hands and peeling.
In fact, as early as 199 1 year, a study in the journal of minimally invasive medicine pointed out that doctors occasionally found that vitamin C solution had a significant effect on hand peeling at work.
The specific method is: wash your hands, pour vitamin C solution into your palm, and then wipe the liquid medicine evenly with your palms; Wash off when the liquid medicine turns white after drying; Two times a day, 2 ml each time, no side effects.
5. Relieve colds
When we have a cold, we often see "vitamin C supplementation". Is vitamin C supplementation really helpful for relieving colds?
In 2 14, a study published in China Journal of Practical Medicine found that vitamin C is a non-toxic nutrient, water-soluble, and the excess in the patient's body will be excreted with water, which can also stimulate the patient's body to produce interferon, thus destroying the virus and reducing the combination between the virus and white blood cells, so that the number of white blood cells remains relatively stable. After this treatment, the average antipyretic time, the improvement time of cold symptoms and the cure time in the experimental group were significantly better than those in the control group.
The study also found that supplementing a certain amount of vitamin C to patients with early viral cold can effectively improve their immunity and resistance, and patients should drink more water when supplementing vitamin C.
6, enhance human immunity
At present, the most important function of vitamin C is to improve the body's immunity. Immunity is a physiological function of the human body, and the human body relies on this function to identify "self" and "non-self" components, thus destroying and rejecting antigenic substances that enter the human body.
There are important cells in the body's immune response function, called lymphocytes, which are composed of T lymphocytes, B lymphocytes and natural killer cells. They can be compared to the sword of human internal defense.
According to an article in February18 in the medical journal Antioxidants, vitamin C can promote the proliferation of T cells and NK cells and affect their cell functions.
Wonderful use of vitamin c 3
Vitamin C is a redox agent, which has a certain antioxidant effect.
The main functions are as follows:
1, promote the biosynthesis of bone collagen, which can make the wound heal faster when used in tissue injury, promote the synthesis of collagen, prevent gum bleeding and promote the growth of teeth and bones, which is a common function of vitamin C.
2, promote the metabolism of tyrosine and tryptophan in amino acids, prolong the physical life, and enhance the body's anti-stress ability and immunity to the external environment.
3. Improve the absorption of iron, calcium and folic acid, improve the metabolism of fats and lipids, especially cholesterol, and prevent cardiovascular diseases.
4, promote the reduction of skin pigmentation, thereby reducing black spots and freckles and making the skin whiter.
5, vitamin C has other beauty effects, such as intake of vitamin C, which is of great help to increase collagen and improve skin texture.
Therefore, taking vitamin C regularly is of great benefit to the body.

Is it ok to take a vitamin C every day?
Taking vitamin C also needs to be divided into different situations: healthy people are not recommended to take one tablet every day. The amount of the substance ingested from food is basically enough for the human body to need every day, so it is not necessary to take a vitamin C tablet specially.
If people really need to take it, they should also take it under the guidance of a doctor, but they can't take it too much for a long time, which will do great harm to their health.
Related knowledge: The theoretical basis of taking one tablet of vitamin C every day is that the recommended intake of vitamin C for preventing non-communicable chronic diseases is 200mg in the "Reference Intake of Dietary Nutrients for China Residents 20 13" issued by China Nutrition Society, while the average person takes about 100mg from food, so he has to take an extra tablet of vitamin C 100mg.
It is harmful for healthy people to eat a lot of vitamin C for a long time.
If you take vitamin C tablets for a long time, it may have the following side effects: it may cause diarrhea, hyperacidity and stones; It is easy to cause thrombosis and increase the risk of stroke; It may affect the fertility of women and the development of the fetus; May cause hyperuricemia and uric acid stones; There are also some people who take vitamin C tablets orally for a long time to enhance their immunity because of their poor immune system, but if they stop taking the drugs suddenly, they will cause tooth loosening and gum bleeding.
Is vitamin C harmful to one tablet a day?
Efficacy: Vitamin C can capture free radicals, which can prevent diseases such as cancer, arteriosclerosis and rheumatism. In addition, it can enhance immunity and is good for skin, gums and nerves.
Side effects: Up to now, vitamin C is considered harmless, because the kidney can excrete excess vitamin C. A newly published research report in the United States points out that there is a large amount of vitamin C circulation in the body, which is not conducive to wound healing. Taking more than 1000 mg of vitamin C every day will lead to diarrhea, infertility in kidney calculi and even genetic defects.
Adverse reactions of taking vitamin c:
According to domestic and foreign studies, with the increasing dosage of vitamin C, there are more and more adverse reactions.
Diarrhea. Taking1~ 4 grams of vitamin c every day can accelerate the peristalsis of small intestine and cause abdominal pain and diarrhea.
Gastric bleeding. Long-term oral intake of vitamin C will cause nausea and vomiting. At the same time, due to the increase of gastric acid secretion, it can aggravate the pain of gastric and duodenal ulcers, and in severe cases, it can also lead to gastric mucosal congestion and edema, resulting in gastric bleeding.
Stones. After a large amount of vitamin C enters the human body, most of it is metabolized and decomposed by the liver, and the final product is oxalic acid, which is excreted from urine to become oxalate; Some studies have found that taking 4 grams of vitamin C orally every day, the content of oxalate in urine will surge from 58 mg to 620 mg within 24 hours. If you continue to take it, oxalate will increase continuously, and it is easy to form urinary calculi.
Gout. Gout is a disease caused by the disorder of purine metabolism in the body, which is mainly manifested by the high concentration of uric acid in blood, resulting in a series of symptoms in joints, connective tissues and kidneys. Taking a large amount of vitamin C can cause a sharp increase in uric acid and induce gout.
Infant dependence. Pregnant women take a lot of vitamin C continuously, which will make the fetus dependent on the medicine. After birth, if the baby is not given a large amount of vitamin C, scurvy may occur, such as listlessness, gingival swelling and bleeding, and subcutaneous bleeding; There are even symptoms such as gastrointestinal bleeding and urinary tract bleeding.
Orthopedic diseases in children. Children who take a large amount of vitamin C can suffer from orthopedic diseases with a high incidence.
Infertility. Women of childbearing age take a lot of vitamin C for a long time, which will reduce their fertility.
Immunity is reduced. Taking a large amount of vitamin C for a long time can reduce the phagocytosis of white blood cells and reduce the body's disease resistance.
Allergic reaction. The main manifestations are rash, nausea and vomiting, and anaphylactic shock can occur in severe cases, so it cannot be abused.

Dietary taboos of vitamin c
1, milk
Vitamin C is best not to be eaten with milk. Milk contains an oxidizing substance, vitamin B2. At this time, taking vitamin C is easy to be oxidized by vitamin B2, and at the same time, vitamin B2 is reduced, both of which have lost their due functions.
Except milk, other dairy products such as milk slices and cheese should not be eaten with vitamin C.
2. Animal liver
It is best not to eat vitamin C with animal liver. This is because the copper contained in animal liver is easy to react with vitamin C, which makes vitamin C lose its original function.
In addition to animal liver, other copper-rich products such as chicken gizzards, oysters, green beans and so on.
3. Alcoholic beverages
It is best not to eat vitamin C with alcoholic beverages. Alcohol will affect the absorption of vitamin C in the stomach, and the normal metabolism of alcohol will be affected without vitamin C.
4. Smoking
It is best not to smoke when taking vitamin C. Studies have shown that smoking can change the performance of vitamin C in saliva and become a substance harmful to health. But smokers can eat more fruits and vegetables in peacetime to help reduce the harm of smoking.
5. Shellfish aquatic products
Vitamin C is best not to drink shellfish and eat it together. If it is mixed in large quantities for a long time, it may lead to toxic accumulation in the body. It's okay to eat together once in a while
6, some drugs
When taking vitamin C, some drugs such as sulfonamides, aspirin and cholesterol-lowering drugs should not be taken with it. Sulfanilamide drugs are easy to produce sulfanilamide crystals and cause stones, while aspirin is easy to affect the efficacy and the absorption and utilization of vitamin C.
