 Yogurt is white? The worlds top science journal: Taking probiotics is basically useless.


Then, on September 6, the worlds leading science and technology news magazine, New Scientist, followed up with a story: Probiotics are mostly useless and can actually hurt you. Next is the probiotics useless which we saw in the past few days.

Net friend:

Is probiotics really useless?

When probiotics were useless, many people were not calm when the news was announced. You know, probiotics are called probiotics, as the name suggests, because they are good for the body.

If the probiotics are really useless, then maybe the yogurt we usually drink is white. This is a bad news for yogurt lovers and the health care crowd. After all, many people even lick the yogurt lid, they feel that they eat is full of health and happiness ah!

But the effect of probiotics on human body has been recognized for a long time.

In 2001, the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) defined probiotics as living bacteria that can play an effective role in the health of food users by ingesting appropriate amounts.

Chinas Prebiotic Health Food Declaration and Review Regulations (Trial) (Food and Drug Supervision [2005] 202): Prebiotic health food is a kind of micro-ecological products which can promote the ecological balance of intestinal flora and play a beneficial role in human body.

It is most likely to be over interpretation of research results.

So how did this paper, which was included in Cell, come to the conclusion that probiotics are useless?

The reporter interviewed Dr. Gao, a molecular nutritionist who has studied the probiotic mechanism of lactic acid bacteria, and is now an editor of Fruit Shell Net. He believed that the overinterpretation of the research results by foreign media and many domestic publicists may mislead the public.

In fact, the first paper examined the colonization of 11 mixed probiotics in the host intestine and found that colonization varied from person to person, with some colonizing in the intestine and others not in the intestine. This finding highlights the fact that probiotics may need to be customized according to different peoples physical and gut characteristics, which does not equate to probiotics being unproductive.

Then, what is colonization? Pan Wensheng, director of gastroenterology at Zhejiang Peoples Hospital, explained that probiotics settle in the intestine. Generally speaking, probiotics can be left in the intestine, and can be in harmony with other intestinal sister in order to play a role.

In the second study, the team used the same batch of mixed probiotics (11 species) as in the first, and recruited a small group of volunteers, who were given antibiotics for a period of time (destroying the normal structure of the flora), and then divided them into three groups. One group ate pre-stored fecal bacteria from their respective intestines, and the other group took mixed bacteria. Probiotics, the rest of the normal diet, do not take strains, as a control.

The results showed that those taking fecal bacteria recovered the fastest, while those taking probiotics recovered the slowest. However, the slow recovery of the original bacterial structure is not the same as that of probiotics.

In other words, judging from the two articles themselves, there is no direct reference to the beneficial or harmful statements of probiotics.

At present, the role of probiotics may be overstated.

So, what are the experts opinions about whether beneficial bacteria are beneficial to human body?

Cao Qian, deputy director of the Center for Inflammatory Bowel Disease, Shao Yifu Hospital, Zhejiang University Medical College, said: Although probiotics are used both in clinic and in non-prescription medicine, people will think probiotics is a good thing, but at present, the role of probiotics may be overstated, we can not say probiotics to now. What are the advantages of the bottom?

Even if we do the experiment, we can not simply divide the subjects into two groups: those who eat probiotics and those who do not eat probiotics for comparison. The main reason is that we can not control the number of original bacteria in the gut of the subjects except eating and not eating this variable.

For different patients, it may be effective for some people to use probiotics, but some people are not effective, he said. Cao said that any treatment should be symptomatic and correct. And in the course of the treatment of bowel disease, often take a variety of treatment and a variety of drugs, which is difficult to say that the real key role must be probiotics.

Every individual has a different number of bacteria in the gut, Pan said. People cant know exactly how many bacteria are in the gut and how many bacteria are in the gut that are normal. Its not like we can detect white blood cells in the human body with an instrument. Quantity to determine whether a person has inflammation.

However, Previous studies have shown that probiotics are effective in treating inflammatory bowel diseases, nonspecific enteritis, hepatic encephalopathy, and some functional bowel diseases such as indigestion and abdominal pain, and can alleviate symptoms of the disease.

As Director Pan said, the small intestinal world is as complex as a mystery to humans, and there are still many uncertainties.

Is yogurt really white?

Cao suggested that probiotics are not a panacea. Maybe normal people do not necessarily need supplements. When people dont fully understand probiotics and intestinal problems, we should treat probiotics correctly and use probiotics carefully. Therefore, it can only be said that the two papers in Cell are a new discovery in the study of intestinal probiotics. It reminds people that the function of probiotics may be exaggerated to some extent. The type, quantity and individual situation of probiotics affect the direction and limits of probiotics. Of course, yogurt can be continued to drink, although the number of probiotics in yogurt is not enough to play a role in the human intestinal tract, and some yogurt in the process of active probiotics will be killed, but yogurt also contains other nutrients. Most importantly, for many yogurt lovers, theres no other reason to drink yogurt. Source: Legal Evening News - opinion editor: Qian Yue Xiao _NBJ10675
