In recent years, a mysterious food called enzyme has swept the world. On the internet, in newspapers, on TV, publicity is everywhere. This new thing seems to have penetrated into thousands of households overnight. What exactly is an enzyme and what is its effect on human health? Let's get to know each other.

What exactly is an enzyme?

Enzyme sounds like a tall name, but in fact, we are almost familiar with it, because its other name is enzyme, and its essence is protein, which is the catalyst of chemical reaction in the body. Some people say that enzymes are amino acids and are not rigorous. Amino acids are single, small molecular substances, while enzymes, that is, enzymes, are composed of dozens to hundreds or even thousands of amino acids, showing different structures according to different functions. Therefore, to be precise, enzyme is a kind of protein, but unlike ordinary protein, it is an active macromolecule with catalytic effect, and the most basic unit of protein decomposition is amino acid, so enzyme is a substance with special biological activity composed of amino acids.

How did the enzyme come from?

If it is an enzyme produced by a regular manufacturer, it will generally go through several stages: material selection, cleaning, drying, cutting, fermentation, chelating, quality control, packaging and filling, and entering the circulation. If the environment meets the production standards and the quality is guaranteed, the enzymes bought by consumers have no health risks; If the living environment and hygiene are not up to standard, and the production technology is backward, the product may deteriorate and be contaminated by microorganisms, and it is definitely unsafe to eat.

But even if there is no health risk, it does not mean that it must be beneficial. Enzymes are just protein, and its so-called therapeutic effect on diseases is just all kinds of exaggerated propaganda without scientific basis carried out by businesses for the benefit. Even if you make your own enzymes, you'd better eat fruit directly. Poor fermentation control is easy to cause pollution, and eating is also risky.

First, can you lose weight? Of course not. The reason for this is the following：

1. There is no scientific evidence that enzymes lacking in human body can be supplemented by oral administration. The main reason is digestion.

The pH value of gastric juice in normal people is 0.9 ~ 1.8, and the pH value of gastric juice in people with hyperacidity is even lower. The essence of enzyme is active protein, which means that the enzyme itself is a kind of protein, and it will also be baptized by gastric acid in the stomach. Most of its structure has been destroyed, denatured and inactivated, and it has long lost its function. So there is no effect of losing weight at all. (Very simple, the milk that children eat in their stomachs after vomiting for a period of time is not uniform, but a tofu-like object, which is denatured and caked. Inactivation, denaturation and coagulation are no longer milk, and of course there is no enzyme activity, not to mention that children's stomach acid is much less than that of adults. )

Therefore, among oral enzyme preparations, only enzymes that improve gastrointestinal digestion, such as yeast, can still play a role, while those enzymes that need to enter the body through blood circulation cannot be absorbed into active prototypes through the gastrointestinal tract.

In the products on the market, if enzymes have some uses, pure enzyme preparations are completely commercial lies, because at present all enzyme preparations (except intestinal digestive enzymes) need injection to play a role.

2. Of course, there are a few protein who can resist the digestion of gastric acid and trypsin, and can enter the human body in the form of protein, but these protein will not produce physiological effects that are useful to human body, but are often harmful to health. For example, the toxin of botulinum toxin is a small molecule protein, which can enter the body through intestinal mucosa in the prototype, causing nerve conduction block; The consequence of prion protein entering human body is mad cow disease with the destruction of central nervous system as the main manifestation; There are also some protein which are not toxic in themselves, but can cause allergic reactions in some sensitive people after directly entering the human body. Exceptionally, newborns can get active immunoglobulin from their mother's colostrum to help resist external microorganisms. This is because the neonatal gastric acid secretion ability is poor, and the acidity is not enough to denature immunoglobulin. With the development of babies and the enhancement of gastric acid secretion, they will soon lose the privilege of obtaining active immunoglobulin.

3. If even a small amount of enzyme is undigested, it is difficult to absorb fat from the small intestine to the outside of the cell mitochondria, and the burning of fat cells entering the mitochondria is controlled by rate-limiting enzymes, so it cannot promote fat entering the mitochondria.

Second, it is not reliable that the same enzyme can lose weight. What is the reason?

Many female friends said that although it is impossible to lose weight by analyzing enzymes in theory, they really lost weight after eating enzymes for a while. What is the reason? In fact, many women do have weight changes after eating, but many reasons are due to the placebo effect. Especially for girls who have a strong belief in weight loss, no matter what relevant weight loss products they eat, they all have certain psychological hints. Therefore, don't judge that enzymes have the function of losing weight. What you see may be an illusion. There is another important reason, if some pharmaceutical ingredients are added to the enzyme products, it will also play a certain role in slimming, but its effect is brought by the pharmaceutical ingredients. So, don't be too superstitious about enzyme to lose weight. If the dosage of the added pharmaceutical ingredients is not well controlled, it will also cause harm to the body due to accidental intake.

Third, many businesses advertise that enzymes have therapeutic effects on diabetes and other chronic diseases. Is that really the case?

An enzyme is an enzyme, and its essence is protein. It is said that it has a therapeutic effect on chronic diseases, which is inherently problematic. Secondly, after the enzyme is digested in the stomach, it is decomposed into amino acid fragments, which are absorbed where needed, and will not play a role in a propaganda way at all. Therefore, it is not reliable to treat chronic diseases with enzymes. Of course, unless you add chemicals or drugs that you can't know, aren't you worried if you don't know? It may also delay the best treatment time and aggravate the condition.
