2. Don't be superstitious about imported enzymes.
3. Don't be superstitious about homemade enzymes.
4. Don't be superstitious about any product advertisements, celebrity endorsements, expert endorsements and appearances.
Merchants' propaganda is also dazzling, with various functions, such as moistening the intestines and relaxing bowels, regulating the stomach and intestines, promoting digestion, resisting oxidation, resisting bacteria and diminishing inflammation, improving immunity, losing weight, beautifying and whitening. (Some are obviously exaggerating propaganda, so you can report 1233 1).
Are there any scientific reasons for these functions of enzymes? Is it useful to drink enzymes?
Phytochemical constituents
Some people think that enzymes are rich in phytochemicals such as polyphenols, flavonoids and organic acids.
However, these ingredients are not uncommon. For example, polyphenols and flavonoids are ubiquitous in plants. You can eat fruits and vegetables directly to get more polyphenols and flavonoids.
In fact, they are not obtained by fermentation because they are useless to microorganisms.
As for organic acids, oxalic acid, tartaric acid, malic acid, lactic acid, acetic acid and citric acid are common enzymes.
Among them, oxalic acid and tartaric acid are common components in plants. For example, spinach is astringent because of oxalic acid, and there is a lot of tartaric acid in grapes.
Lactic acid and acetic acid are typical fermentation products of lactic acid bacteria and acetic acid bacteria respectively, but isn't it more direct to drink yogurt, be jealous and eat pickles and sauerkraut?
Other organic acids are produced and consumed by human body every day, not to mention various organic acids produced by intestinal flora.
Promote digestion?
Enzyme is the old name of enzyme, so various active enzymes have become the symbolic components of enzyme, such as amylase, lipase, protease and so on.
Because of these enzymes, merchants claim that enzymes can help digestion and even reduce fat, but this statement is not scientific.
First of all, biological enzymes need a specific PH environment to function, and the enzyme activity detected in vitro is likely to be ineffective in the stomach.
Besides, these enzymes themselves are protein, which will be cut into pieces by pepsin and trypsin in human digestive tract and lose their original activity.
Secondly, enzymes are very common substances in organisms and exist in bacteria, molds, yeasts, animals and plants.
Human intestinal flora also produces many enzymes, including lipase, protease, amylase, cellulase and so on.
All together, it must be far more than the enzyme in the enzyme.
In addition, the enzyme beverage will be sterilized and preserved, which will inactivate the enzyme.
It is really a mystery how much enzyme activity can reach your digestive tract even if it is transported and stored at room temperature.
Improve intestinal function?
There is a small amount of soluble dietary fiber in fruit and vegetable fermented juice, and a small amount of organic acid seems to be beneficial to intestinal flora.
But if you eat fresh fruits and vegetables and coarse grains directly, the effect should be better. After all, the crude fiber in fruits and vegetables can also promote intestinal peristalsis.
Some enzyme products add dietary fiber (prebiotics) such as oligosaccharides and inulin or directly add probiotics, so it has obvious effect on improving intestinal flora and relieving constipation.
But you don't need to eat enzymes. The effect of eating oligosaccharides directly is more obvious. The price is much cheaper. 50 yuan, a catty of xylooligosaccharide is enough for you to eat for almost a year.
I saw it: after eating so many probiotics, I didn't expect the strongest prebiotic to be in the corncob you threw!
Antioxidants?
Enzymes contain many antioxidant components, such as polyphenols and flavonoids, but plants generally contain these components. Obviously, eating fruits and vegetables is more efficient than drinking enzymes.
There is superoxide dismutase (SOD) in the enzyme, which is "highlighted and underlined" for you, because many people think it can beautify and resist aging.
In fact, SOD is not a magical thing, it will be produced by the human body itself, and there are more SOD in bananas, kiwis, pineapples and other fruits and vegetables.
However, it is difficult for exogenous SOD to play its role in human body. This is because SOD is essentially a kind of protein with relatively large molecular weight, and it is unlikely to directly enter human tissues and cells to complete the anti-oxidation mission.
Moreover, in the gastrointestinal environment, the fate of foreign SOD is likely to be tossed to death by various proteases.
At present, there is indeed an "attempt" to treat cardiovascular and cerebrovascular diseases with SOD in clinic, but it is direct intravenous injection.
Lose weight?
Enzymes may be a fashion for young girls to lose weight, and there are indeed girls who have lost weight successfully on the Internet to "share their experiences".
However, the principle of enzyme weight loss has nothing to do with the composition of enzyme. The key is a word hungry!
Enzymes are deficient in nutrition. If enzymes are used instead of three meals a day, the energy intake is seriously insufficient.
Take an enzyme imported from Japan as an example. Drinking three meals a day according to the recommended amount only has 265,438+00 kilocalories, while a young girl who is not very active needs at least 65,438+0,500 kilocalories a day. Can this not be thin?
Why not recommend drinking enzymes for a week? Because I'm afraid you'll starve to death, dear
If this is all due to enzymes, then I think Guanyin soil is better than drinking enzymes to lose weight.
There is no shortcut to lose weight, eating less and exercising more is the right way!
Self-made enzyme
Many people feel that things sold outside are not at ease, and they are quite expensive. There is really no need to simply do it yourself.
Originally, enzymes have no practical function, and there are still many safety hazards in homemade enzymes.
First of all, if the fermentation process is contaminated by miscellaneous bacteria, it may lead to poisoning.
For example, a careless mother in Guangdong gave her child melon water (actually melon enzyme) that had been stored for three years, which led to nitrite poisoning and almost died.
Contaminated Staphylococcus aureus, Bacillus cereus and other pathogenic bacteria may also cause food poisoning.
Secondly, some yeasts can ferment to produce ethanol.
If sugar or honey is added to the enzyme, the final alcohol content can be higher than that of beer, and the actual harm to the body is far greater than the benefits of other ingredients.
Finally, it has been a long time since human beings used microorganisms in nature to ferment food. Why should we respect enzymes alone?
Why pursue sweet kimchi from Japan and ignore salty kimchi that has been passed down in China for thousands of years?
Pickled sauerkraut in Northeast China, pickles in Sichuan, sweet rice wine and sour vinegar are all traditional enzymes, aren't they?
