For beauty lovers, hyaluronic acid products must not be unfamiliar, which is often used to fill the face, for skin moisturizing and hydration, shaping, anti-aging wrinkle removal, whitening and so on. Nowadays, hyaluronic acid food wind has blown on the market, and milk tea, drinks, yogurt, gummies, etc. can be added hyaluronic acid for beauty.

So, are these hyaluronic acid foods reliable?

？？？

Is hyaluronic acid used in food compliant?

The relevant regulations have indeed approved it as a health food raw material

In 2021, the use of sodium hyaluronate will be expanded to include milk and dairy products, beverages, alcohol, candy, etc., and the variety of foods that can add hyaluronic acid will be expanded. After gummies, oral liquids, and drinking water, many milk tea shops also sell drinks containing hyaluronic acid ingredients. On social platforms, there are also bloggers who share hyaluronic yogurt tea and hyaluronic acid yogurt, and the tea industry has also blown up the "hyaluronic acid" wind.

According to the information, hyaluronic acid, also known as hyaluronic acid, is widely present in our skin and fills the gap between human cells and collagen fibers. Hyaluronic acid has a strong water absorption and can absorb 500 times more water than itself. It is a natural moisturizer. But with age, hyaluronic acid in the human body will gradually lose, resulting in some signs of skin aging. Hyaluronic acid was first isolated and extracted from bull's eye vitreous by ophthalmologists and can now be obtained through microbial fermentation and animal tissue extraction. In order to alleviate the problem of skin aging, hyaluronic acid products are often injected under the skin as a filler in the medical aesthetic field to solve skin problems such as wrinkles.

In addition to being used in the field of cosmetics, on January 7, 2021, the National Health Commission issued the "Announcement on 15 Kinds of "Three New Foods" such as Cicada Flower Fruiting Entities (Artificial cultivation)" and other "three new foods", which also shows that sodium hyaluronate was approved as a new resource food in the mainland in 2008, and the scope of use is health food raw materials. Sodium hyaluronate is the sodium salt form of hyaluronic acid, the application of hyaluronic acid is generally in the form of sodium salt, through this ionic form can improve water solubility, in the food processing industry is more suitable for application.

Sodium hyaluronate and its main ingredient products are currently allowed to be added to foods or dietary supplements in Japan, South Korea, the United States, european union countries, Australia, New Zealand and Brazil. Based on the approved use in other countries and international organizations, the National Health Commission approved the expansion of the use of sodium hyaluronate into milk and dairy products, beverages, alcohol, cocoa products, chocolate and chocolate products (including cocoa butter chocolate and products) and confectionery, frozen drinks.

Do foods containing hyaluronic acid really have a cosmetic effect?

The effect may be minimal

After the use of sodium hyaluronate has been expanded, its imagination space in the food industry has gradually become larger.

So, do such products really have beauty effects?

For its beauty effect, Ruan Guangfeng, director of the Science and Technology Communication Department of the Science and Technology Communication Center of Kexin Food and Health Information Exchange Center, said in an interview that oral hyaluronic acid cannot be directly absorbed by the human body, and the macromolecular hyaluronic acid after oral administration will be digested and decomposed through the gastrointestinal tract, and first converted into small molecules of sugar before it can be absorbed and utilized by the human body. Relying on oral hyaluronic acid to hydrate the skin may have minimal results.

Professor Sheng Qing of the College of Life Sciences and Medicine of Zhejiang Sci-Tech University also introduced in an interview with the media that in the current research, oral high molecular weight hyaluronic acid, about 76.5% of which is metabolized by the liver, will become energy and be consumed, and only about 8.8% will be transported to various tissues and organs to play a biological role. In other words, most of the hyaluronic acid eaten orally is actually metabolized in the form of energy.

For the popular hyaluronic yogurt tea on the market, Liang Tingting, a nutritionist in charge of the Second Affiliated Hospital of Nanjing Medical University, also introduced that after hyaluronic acid is eaten, the human body will produce a certain metabolism, and about 70% will be consumed in the form of energy. Only 8% to 10% of the remaining can play a role. Milk tea is very small in the first place, and if you want to drink milk tea to achieve anti-aging, anti-wrinkle, moisturizing or promote the balance of microflora in the body, this intake is minimal.

Compared with oral hyaluronic acid, injections and smears may be more effective. According to Long Xiao, deputy director of the Department of Plastic and Aesthetic Surgery of Peking Union Medical College Hospital, applying hyaluronic acid belongs to the category of life beauty, while injectable hyaluronic acid will break the skin and enter the deep layer of the skin, which can be more directly supplemented to the needed parts. However, injectable hyaluronic acid belongs to the "mechanical brand" products of medical devices, and the requirements in various aspects such as health standards are higher. However, because injectable hyaluronic acid is invasive and has certain risks, it is recommended to be carried out in a regular beauty institution.

Are foods containing hyaluronic acid safe for all?

It is safe in theory, but there are contraindications to people

For its safety, because our human body itself is also synthesizing hyaluronic acid (hyaluronic acid), mainly in 3 parts of the human body with high content, namely the skin, joints and eyes. Substances synthesized by the body's own tissues are inherently safe. Therefore, Lu Wenwei, a professor at the Food College of Jiangnan University, once said in an interview with the media that from the perspective of the hyaluronic acid molecule itself, in theory, there is no problem with its safety.

However, sodium hyaluronate is not suitable for some people. Chen Jian, director of the Future Food Science Center of Jiangnan University, once pointed out that the edible safety data of hyaluronic acid food in infants, pregnant women and lactating women is insufficient, and from the perspective of risk prevention principle, the above groups should not be eaten, and the label and instructions should be marked as inappropriate for people.

For net red foods such as hyaluronic yogurt tea, Liang Tingting said that because most milk tea has higher calories, it is not recommended to supplement hyaluronic acid by drinking milk tea. If there is a definite need, it is best to determine a reasonable dose through the diagnosis of a doctor. Currently, the upper limit of hyaluronic acid consumption is 200 mg per day.
