Vitamin C and some facts.

Vitamin C

 

Vitamin C is the main component in Lemons.

Introduction:

VitaminC is an essential nutrient for our health. Present mostly in citrus fruits like oranges and lemon. From our body needs to whitening and health care, the function of vitamin C has also been spread more and more "powerful". Because of its antioxidant effect, vitamin C has high hopes for whitening. In daily life, we often think that oral ulcers and bleeding gums are caused by vitamin C deficiency; even the long barbs on the hands are related to vitamin C deficiency.

It is true? Is that right?

 

 Oral ulcers and bleeding gums are caused by a lack of vitamin C; if you have barbs on your hands, you should eat more vitamin C... Do you often hear this advice in your life?

 Many people regard vitamin C as an omnipotent panacea for all diseases. Is vitamin C really such a "god"? Some people even think that even if the disease cannot be cured, adding more vitamin C is always harmless to the body. Is this really the case?

 Misunderstanding 1:  Eat a lot of vitamin C to turn white

 

Beauty of the heart is in everyone. As the saying goes, one white covers one hundred ugly. What a racist saying it is.

 Many people who love so-called (whitening) beauty regard it as a good whitening product and hence they take it in large amounts.

In this regard, Li Heng, director of the Department of Dermatology of Hubei, Provincial Hospital of Traditional Chinese Medicine, said in an interview with a reporter from Science and Technology Daily that,

“vitamin C, also known as ascorbic acid, has acid properties, has strong reducing properties, and is an antioxidant. We know that the root cause of skin darkening is melanin deposition, and melanin is secreted when tyrosine is converted into Dopa. When Dopa secretes melanin, dopa must be converted into dopaquinone, further, it converts to melanin, vitamin C has the ability to reduce ubiquinone & prevents the production of melanin. According to this mechanism, it can be seen that vitamin C has a whitening effect.”

Ruan Guangfeng, director of the Science and Technology Department of the Food and Nutrition Information Exchange Center said that some claims claim that vitamin C has good antioxidant activity, which can inhibit the activation of tyrosine, so that tyrosine will not become melanin(with the series of reactions), which can play a role in whitening. There is some truth to this statement, but in fact, there is no particularly sufficient evidence.

In addition, because vitamin C has an antioxidant effect, it can promote the formation of collagen, rejuvenate the skin, delay skin aging, and indirectly make the skin whiter.

But it does not mean that the more you eat, the better. There are dosage requirements. If you take a large amount of vitamin C for a long time, it will hurt your body. Because vitamin C is acidic, the urine becomes acidic, and it is easy to form calcium oxalate stones in the body And kidney stones.

"Li Heng emphasized that at the same time, large doses of vitamin C can counteract the anticoagulant effects of heparin(Blood thinner) and dicoumarin(an oral anticoagulant drug), leading to thrombosis, which makes patients with cardiovascular and cerebrovascular diseases more likely to have cerebral infarction (stroke).

vitamin C and its content;

 Ingestion of vitamin B12 food at the same time can destroy a considerable amount of vitamin B12 and after a large amount of vitamin B12 is destroyed, people are susceptible to anemia.

 
Less myths more facts.

Misunderstanding 2;  Oral ulcers and bleeding gums are caused by lack of vitamin C

 Bleeding gums are encountered by almost everyone in life. In the case of fatigue and irregular life, bleeding gums often occur when brushing teeth. Some people think that bleeding gums are a manifestation of a lack of certain vitamins. Is it true?

 Dentist interviewed by a reporter from  Science and Technology Daily said that 

 f
“although a long-term severe lack of vitamin C does cause bleeding and swelling of the gums (the "scurvy" suffered by sailors in the past is the reason), if you do not eat foods containing vitamin C such as vegetables, fruits, milk, etc. for a month. 

Otherwise, except for a few people, it is caused by systemic diseases such as blood diseases.”

 Vitamin C is an acidic organic substance that has anti-bleeding effect. When the human body is severely lacking it, it can cause gum bleeding.

 But not all gum bleeding can be attributed entirely to vitamin C deficiency. Modern medicine believes that recurrent oral ulcers are closely related to the immune system. Some patients show immunodeficiency, and some patients show autoimmune response. Due to various factors, the body's normal immune system reacts to self-tissue antigens and causes tissue destruction and disease.

Oral ulcers may be related to some diseases or symptoms, such as digestive system diseases, gastric ulcers, duodenal ulcers, etc. In addition, anemia, partial eclipse, indigestion, mental stress, and high work pressure often cause frequent attacks of oral ulcers. 　　

 

 Misunderstanding 3: Barbs grow on fingers that lack vitamin C

 

In winter, some people tend to grow barbs on their hands.

"The long finger barbs have nothing to do with the lack of vitamin C."

Li Heng said that long finger barbs are keratinized protrusions around the nails. Many people will pull them off by themselves. After they are pulled off, there will be partial keratinous defects.

The main cause of barbs is dry skin, dry keratinous skin will lift up, and barbs will form at this time; poor eating habits, people with trace element deficiency, malnutrition caused by picky eaters or partial eclipses are also easy to form Punctures; tearing is an irregular injury. Incorrect tearing methods can cause local skin damage, but it is easier to form barbs.

It can be seen from the above that the formation of barbs is not closely related to vitamin C.

The formation of periungual barbs is mainly due to the separation of the stratum corneum due to excessive dryness. The stratum corneum is the thin layer of dead skin on the outermost skin layer and is the first barrier of the skin. There is a layer of sebum on the surface of the stratum corneum (outer layer of epidermis), which is a natural moisturizing agent, which can reduce the evaporation of water in the stratum corneum, ensure its proper water content, and make the stratum corneum and the skin below it adhere closely.

Soap, detergent, or physical friction removes the sebum on the surface of the skin, which will cause the stratum corneum to lose its protection, and the stratum corneum will evaporate excessively and dry and peel off.

 Li Heng suggested that after the barbs appear, they must not be pulled off. They should be cut off neatly with nail scissors to reduce skin damage. At the same time, pay attention to applying hand cream that moisturizes the skin in time to keep the local skin moisturized.

Misunderstanding 4;  Synthetic vitamin C is not as good as natural

"It's a medicine that is three-point poison" and "Synthetic is of course not as good as natural." People who have bought vitamin C often hear such remarks, so they often spend a lot of money to buy "natural" vitamin C and manufacturers produce a variety of different flavors. Of vitamin C products and claim to have different effects.

Is there really such a big gap between these products? 　

Indeed, when you go to a pharmacy, you will find that the price of vitamin C ranges from a few dollars to hundreds of dollars, and the styles are also varied, including effervescent tablets, chewable tablets, lozenges, and so on.

 In this regard, some experts pointed out that  vitamin C of 2$ in the hospital is generally pure vitamin C, which is purely from the perspective of supplementing vitamin C, and is a medicine; while most of the health products bought in pharmacies are health products, which are based on purification technology. The added excipients are different from medicines, which also leads to the difference in prices.

But in the final analysis, under the premise of the same vitamin C content, there is no difference in efficacy between medicinal vitamin C and vitamin C for health care products.

 

Vitamin C is a natural anti-oxidant and is very beneficial for overall health. One must add it to its diet according to the dosage.
