Theoretically speaking, the health benefits of probiotics are still possible, but probiotic drinks have little effect on human health, so we can't trust the role of probiotic drinks too much.

In order to obtain the benefits of probiotics, three conditions must be met.

First, specific strains are needed and must be beneficial to health; Second, make sure there are enough bacteria in the intestine. If the quantity is small, it won't affect. If you can't eat more than 100 million live bacteria at a time, it is generally difficult to have any health care effect, so you should take it continuously for a period of time; The third is to ensure that the product has enough live bacteria to reach the intestine.

First of all, the role of probiotics must be "specific strains", "sufficient quantity" and "living bacteria", but the actual situation is that it is difficult for beneficial bacteria in probiotic drinks to enter our intestines through gastric juice to play a role. Even if it passes the test of gastric juice, the amount that eventually enters the intestine is very small.

The University of London study tested common probiotic products on the market to find out whether those products contain as many microorganisms as they claim, whether these bacteria can pass through the acidic environment of the stomach and whether they can reach the small intestine. Results Only one probiotic can survive in gastric acid environment and reach the small intestine, but the number of bacteria is lower than its claimed number. Therefore, the current probiotic products may not have a good effect on health.

Secondly, probiotics are only auxiliary functions and cannot play a direct therapeutic role. Probiotics research is also to cooperate with drug treatment, not to replace drugs. In 2005, the American Society for Microbiology held a seminar on probiotics. The minutes of the meeting clearly pointed out that up to now, the vast majority of probiotics used by the human body are used to prevent and support the treatment of diseases, not to treat them.

In the past decades, scientists have conducted thousands of studies and published many research results on promoting digestion, improving diarrhea, enhancing immunity, allergies, cancer, women's health and so on. Unfortunately, most probiotic products do not have enough evidence to prove the impact on human health.

If you have a stomachache and constipation, it is still difficult to get immediate therapeutic effect by drinking probiotic drinks. Don't be overly superstitious about the powerful effects of probiotics.

So probiotics are good for the human body, but we must not be too superstitious about its efficacy, because after all, it cannot be compared with medicine.
