There is a new topic in the online debate. The effect of 2 yuan vitamin is the same as 98 yuan vitamin. When we eat melon and browse the Internet for half a world, we finally understand that it's almost the same. The key is whether you can accept 2 yuan vitamin!
According to the sampling survey of relevant departments, 30% of the people in our country usually have insufficient vitamin C intake, so they have to take vitamin C related products to supplement, so as to meet the normal physiological needs. Based on this, the market capacity of vitamin C related products will definitely be greatly improved, and more businesses will be introduced to participate in the division of this' big cake '. This is a good thing, but in order to sell products in a variety of ways, dealers of various suppliers even spread some lies, which is not good. Today, Xiaobian will take stock of some of them for you.
1. Is vitamin C of 98 yuan better than that of 2 yuan?
People who have bought vitamins in drugstores should have heard that the "guide shopping" is "the third poison of drugs" and "the synthetic is not as good as the natural". Some people, like Xiaobian, insist on buying the right medicine: two yuan a bottle of vitamin C and three and a half a bottle of vitamin E. And some people followed the guide to buy hundreds of natural health products.
Is it necessary to buy expensive vitamin C? What's the difference between 98 yuan vitamin C and 2 yuan vitamin C? First of all, the price is not the same. Secondly, the purity is not the same, the two is the "national medicine quasi character", the quality standard includes solvent residue, heavy metal residue and so on, while health products can add flavors and starch to taste and taste better. Finally, the taste of medicine vitamins is not as good as that of health products.
However, the chemical activities of the two forms of VC oxidation and reduction are equal, that is to say, as long as the amount of natural and synthetic vitamins is the same, there is no difference in efficacy. If that doesn't stop you from worrying about synthetic vitamins, eating fruit supplements is a good choice, absolutely natural.
2. Can taking vitamin C prevent cold?
Vitamin can promote the production of immune protein and enhance the body's resistance. Vitamin C supplementation does prevent colds for people who suffer from reduced resistance due to a small number of vitamin deficiencies.
However, this does not mean that vitamin C is the "golden oil" for cold prevention. A research team at the University of Helsinki in Finland did an academic retrospective study: it analyzed 23 experiments and results with the general public as the research object, and found that vitamin C did not play a significant role in cold prevention. People who take 2G vitamin C a day have the same chance of catching a cold as those who only take placebo every day.
That is to say, it is better to take vitamin C to prevent cold. It is better to drink more water, pay attention to ventilation and warmth, and exercise properly to enhance the body's immunity. In addition, targeted influenza vaccination is also a good choice.
3. Can seafood and vitamin C be fatal together?
Last year, there was a news report that a woman ate orange after eating shrimp. Arsenic in shrimp and vitamin C in fruit reacted, which led to her death & hellip; & hellip; for two years, some people said that eating seafood and vitamin C at the same time would produce arsenic with high toxicity.
However, the arsenic in seafood is mainly organic arsenic, inorganic arsenic is very little, accounting for about 4% of the total arsenic content, and it is basically pentavalent arsenic. In short, if you want vitamin C to react with these inorganic arsenic to reduce to arsenic trioxide, you need to eat at least 50 medium-sized apples / 30 pears / 10 oranges / 3 jin of green leafy vegetables at a time.
4. Want whitening, take vitamin C to smear vitamin C injection?
I feel that in the private sector, vitamin C is bound with countless functions because it is cheap and easy to buy, but in fact, most of them are not reliable. For example, whitening, in theory, vitamin C can inhibit the activation of tyrosine and prevent it from turning into melanin, otherwise there will not be so many whitening products with vitamin C as the main ingredient. But if we use vitamin C to whiten with lemonade, the effect is quite limited. After all, we have said that our ordinary people generally lack of vitamin C, after the absorption of the digestive tract, the amount is even more limited, which extra points to skin whitening.
How about eating more? I'll be frank. It's useless for whitening. Eating too much vitamin C will not only not be absorbed and utilized by the body, but also may have many side effects. In addition to the common septicemia, kidney stones and so on, there are also sun dermatitis.
5. Does oral ulcer take vitamin C?
In the past decade or decades, most people believe that oral ulcer can be treated with vitamin C. But in fact, the cause of oral ulcer is always unclear, and it directly affects the formulation of prevention and treatment programs, so there is no strong evidence for vitamin C treatment of oral ulcer at present. And recently, scientists have come to a consensus that common recurrent oral ulcers are not what we usually think of as' vitamin deficiency ': they are not deficient in vitamin C, vitamin B12, folic acid or other trace elements. It is an immune disease affected by genetic factors. Taking vitamin C to treat oral ulcer is the same as taking vitamin C to prevent cold, most of the time is chicken ribs.
Four cooking mistakes will let vitamin C flow away
If you eat a lot of fruits and vegetables every day, but still lack of vitamins, after eliminating the disease factors, you need to see if you have the following cooking mistakes.
1. Squeeze vegetables and fruits
Many people like the juice of fruits and vegetables, but it is a pity that the juice will expose the vitamin C of fruits and vegetables to the air for oxidation and loss; the longer the juice is placed, the more vitamin C will be lost. It doesn't matter if you just like to drink fruit juice. If you want to supplement nutrition through it, you should eat fruit directly.
2. Juice carrot with other fruits and vegetables
Although carrot juice is good to drink, it contains vitamin c oxidase. If it is pressed together with other vegetables, the vitamin C of other vegetables will be destroyed.
3. Green vegetable soup pours the soup
Vitamin C has poor heat resistance. When boiled green leaf vegetables and root vegetables, vitamin C is very easy to drain into the soup, but it is not damaged. Therefore, after eating vegetables and drinking soup together, you can fully absorb vitamin C.
4. Soak vegetables in water for a long time
Many cooks will soak vegetables and fruits in water for a long time in order to 'get rid of pesticides', and some water-soluble vitamins will slowly flow into the soaking water, causing the loss of vitamins.
