CCTV, Beijing, February 25, according to the "News Hyperlink" report of the Voice of China Central Broadcasting Corporation, the National Health Commission issued an announcement: the safety of three new food ingredients including sodium hyaluronate The evaluation materials are reviewed and passed.

Less than two months after the announcement, the market has already seen products such as sodium hyaluronate gummies, and its efficacy has also attracted attention and heated discussions.

　　If "sodium hyaluronate gummy" is not attractive enough, what about "hyaluronic acid gummy"?

　　Hyaluronic acid is a common name. In medical beauty, injection of sodium hyaluronate is usually simply referred to as "hyaluronic acid".

Hyaluronic acid, whose scientific name is hyaluronic acid, can be used in eye surgery and joint treatment.

People are more familiar with using it for facial filling or in cosmetics.

Sodium hyaluronate is the sodium salt form of hyaluronic acid.

　　Therefore, there are also sodium hyaluronate foods in the promotion that they are "eatable hyaluronic acid" and can "nourish hydration."

Such hyaluronic acid foods and drinks are not unusual in some other countries.

However, by taking hyaluronic acid, can you comfortably "eat" the smooth muscles?

Hyaluronic acid, a polysaccharide

　　Previously, sodium hyaluronate was approved as a new resource food in 2008, and the scope of use was a health food raw material.

Now the use of sodium hyaluronate is expanded to include milk and dairy products, beverages, alcohol, cocoa products, chocolate and chocolate products (including cocoa butter substitute chocolate and products), as well as sweets and frozen drinks.

　　Compared with "sodium hyaluronate foods", it seems that the terms "hyaluronic acid foods" or "edible hyaluronic acid" are more likely to attract attention.

What is hyaluronic acid?

　　Chen Fengchao, deputy chief physician of the Medical Aesthetic Center of Beijing Friendship Hospital affiliated to Capital Medical University, introduced that it is a kind of polysaccharide: "It belongs to mucopolysaccharides, and its essence is polysaccharides. Commonly used glucose is monosaccharide, and sucrose in sugarcane is disaccharide, which is transparent. Alkuronic acid is the combination of two monosaccharides, glucuronic acid and glucosamine, which cyclically form a long long chain-sugar chain, which is hyaluronic acid."

　　What is the relationship between the so-called "Hydrokines" and hyaluronic acid, also known as hyaluronic acid?

Hyaluronic acid has physiological functions such as lubrication and moisturizing in the human body, and it is mainly used as a filler when used in beauty.

　　Chen Fengchao introduced that hyaluronic acid has a great effect in the body, has a lubricating effect, and maintains skin elasticity.

There is a large amount of hyaluronic acid in the eyeball, which can maintain the shape of the organ: "As we age, the hyaluronic acid in the skin becomes less and less, and the skin shrinks and becomes dry."

　　When used in cosmetics, hyaluronic acid is a filler, mainly used for filling.

Chen Fengchao introduced that because hyaluronic acid has the same structure as hyaluronic acid in the body, people who are not hypersensitive will have less allergic reactions.

　　Although it is the pursuit of beauty, the filling does not have the physiological effect of hyaluronic acid itself in the body.

Can eating hyaluronic acid produce smooth muscle?

　　Nowadays, hyaluronic acid foods and drinks such as gummies appear.

Hyaluronic acid can be "eaten". Can it play the physiological role of hyaluronic acid in the human body such as moisturizing the skin by eating it in a more convenient and comfortable way?

　　In this regard, Chen Fengchao believes that theoretically speaking, it is difficult to achieve its own physiological effects: “All foods pass through the mouth and enter the gastrointestinal tract, they will be broken down and re-absorbed. Hyaluronic acid is a very long one. Chain, it is broken down into monosaccharides and disaccharides, and then absorbed. This only increases the raw materials for the synthesis of this kind of thing. However, whether this kind of thing can be synthesized again in the body is another matter."

　　The content of hyaluronic acid decreases with age because the human body's ability to produce hyaluronic acid is gradually decreasing.

　　Chen Fengchao said that purely academically, he has not found articles in this area so far: "I think this issue is still open to question if it is to achieve its own physiological effects."

　　This sounds familiar, reminiscent of oral collagen. The principle is similar: the collagen that is eaten is digested and decomposed into tiny amino acids, and then "randomly allocated". The destination is unknown, and it may be transported to various organs and tissues. Only a small part of it will be shipped to the skin.

It is not directly absorbed by the human body after eating, point to point directly to the skin.

　　The desire to "make up what to eat" was shattered.

　　Liu Shaowei, a professor at the School of Bioengineering of East China University of Science and Technology and deputy director of the Food and Drug Supervision Research Center, also said that more experiments and data are needed for the effects that can be achieved by taking hyaluronic acid.

　　He analyzed and pointed out that in theory, all foods that are taken orally in the body will pass through the digestive system, and the sugar will be broken down into small molecules that the body can accept, and then they will synthesize what the body needs.

Hyaluronic acid is a kind of sugar, which undergoes sugar metabolism in the body.

Therefore, theoretically speaking, the original structural components of the body will change: "There are not many experiments that can prove whether it is completely or partially decomposed in the end."

　　In addition, it is worth noting that the interpretation of the relevant announcement pointed out that the safety data of sodium hyaluronate in infants, pregnant women and lactating women is insufficient. Considering the principle of risk prevention, the above population is not suitable for consumption. Labels and instructions Inappropriate people should be marked in, and the recommended consumption should be ≤200 mg/day.
