Today, let's talk about whether the "enzyme" mentioned by many fans has magical effects.
What is an enzyme?
As long as you look at the "enzyme" on Baidu, you will find that this product has many functions, which are not possessed by human beings at all: it can not only beautify and lose weight, but also "anti-aging" and "anti-cancer", with various functions; The aura of "WHO recommendation", "Nobel Prize winner research and development" and "anti-aging revolution sweeping the world" is even more dazzling.
The word "enzyme" came from Japanese, and later entered the mainland through Taiwan Province Province. In fact, it is the enzyme in foreign vests.
In terms of chemical structure, enzyme is a special protein, an active macromolecular substance with catalytic function, and its most basic unit is amino acid.
If the human body lacks enzymes, it will often bring big or small problems and have a great impact on human health. For example, salivary amylase can help starch hydrolysis; Pepsin can help digest protein; Can glucose -6- phosphate dehydrogenase (G6PD) deficiency lead to silkworm disease? Without these enzymes, many biochemical reactions in the human body could not be carried out at all.
However, can the best-selling "enzymes" in the market achieve many functions claimed by merchants?
There are more than 700 kinds of enzymes found in human body, which can be synthesized by themselves without additional supplementation. Even if you need to supplement, you can't take it orally.
The propaganda of the merchants is true, but they won't tell you that oral enzymes are useless.
For example, SOD (Superoxide Dismutase) is one of the most important enzymes in human body, and it is also the main product of enzyme vendors. However, through comparative experiments, it can be found that the SOD activity unit in enzyme preparation is not as good as that in lettuce and tomato of the same quality. So instead of going to the vegetable market to buy two pounds of tomatoes, it is better to spend a lot of money on concept products.

Oral enzymes are more difficult to play the role of enzymes needed by the human body.
The essence of enzyme is protein, and it usually needs specific conditions such as temperature and pH value to exert its activity. However, when the enzyme passes through the digestive tract, it will experience digestive juice such as gastric juice and bile, so it will be denatured or decomposed, and its physiological activity cannot be exerted.
Moreover, most enzymes need to play a role in cells or between cells, and it is difficult for enzymes ingested through the digestive tract to enter cells.
Therefore, I hope that the various effects achieved by oral enzymes can only be a good wish.
Safety of enzyme food
At present, there is no unified product standard of enzyme preparation in China. In other words, ordinary enzyme products are produced and processed as ordinary food, and packaged as "health food" when sold, claiming to have various functions.
If the enzyme product is indeed a product legally claimed to have health care function through clinical nutrition experiments, it must be approved by China Food and Drug Administration, and the product package is printed with a small blue hat logo, and the effective components and stable content are clearly defined in the quality indicators.
Homemade enzymes are risky.
The microbial components on the surface of vegetables and fruits are very diverse. In addition to yeast or lactic acid bacteria needed for fermentation, there are other microorganisms including pathogenic bacteria. If you don't pay attention to hygiene in the production process and mix in miscellaneous bacteria, it may be harmful to human body.
For example, patulin produced by mold, also known as patulin, shows neurotoxicity, embryotoxicity and certain carcinogenicity in animal experiments, and has an inhibitory effect on animal immune system.
What is thankless is not good.
Nitrite is easy to be produced in the fermentation process, and it is difficult to control the strain of self-made enzyme, and the nitrite content in it can not be monitored, which has potential harm.
More importantly, fruit contains a lot of pectin, and methanol is the main product of pectin after microbial fermentation. The lowest dose of oral methanol poisoning is about 100mg/kg body weight, and 0.3 ~ 18~60g/kg can cause death, that is, a person with 60kg body weight will be poisoned if he ingests 6g of methanol, and he will die if he ingests 18~60g. Homemade enzymes are very risky.
Tadpole Jun hereby advises all readers who love life and pursue nutrition. There is no panacea in the world (at least for now). A healthy body still needs regular work and rest, regular exercise, balanced diet and nutrition. Health is not easy, so cherish it.
Truth: Deliberately supplementing enzymes by oral means has no health care effect, and homemade enzymes also have health risks.
