In recent years, from the beverage tablets to capsules, all kinds of probiotic products is popular, people expect swallowed billions of live bacteria to achieve the purpose of medical treatment and care. This lively, mainly from manufacturers clamor. It is said that probiotic products in the world has been formed 19 billion pound market.
However, experts say: In addition to a waste of money, the probiotic products for ordinary people without any additional benefit.
Manufacturers are always claiming that this or that probiotic products have health benefits, such as, "you can help boost the immune system and improve the natural defense capabilities" to "help form a natural bowel regularity" or "maintaining good intestinal bacteria dominant "Wait.
All these claims are covered by an "unverified," the seal.
There was a case can illustrate this point: Since 2009, the European Food Safety Authority (EFSA) received a total of 129 health claims related products, probiotic products application submitted by the manufacturer, so far without any kind of approval.
After a group of international experts from the 20 strict examination, each statement were rejected by the same reason - "could not be confirmed."
Probiotics tag should be disabled
Since December 2012, even in Europe, we have banned the use of 'probiotic' word, which is to prevent some unwary consumers too literally to have a "healthy" this impression.
Technically, this means that no product can be used as the manufacturer claims can bring health benefits of probiotic products to sell. Under the current legal framework in Europe, "probiotic" simply means to tell consumers products added some bacteria.
Scientists now know that each of us live in the intestinal tract are trillions of bacteria to form a complex internal ecosystem - human microbial groups.
In a healthy diet and no antibiotics, "Excuse me" situation, they have maintained a good balance, and related to the host, such as infection, type 2 diabetes and weight gain and other health problems.
Despite growing evidence of the importance of intestinal bacteria, but the problem is to accept incoming called 'good' bacteria that probiotic supplements can help maintain or restore this balance?
Wholesome unproven claims
Scientific research about probiotics is utilized business, be converted into hundreds of millions of the market. In China, the once "encircling the cities" is a representative of three oral. In recent years, a variety of higher grade, an upgraded version is still popular around the world.
Commercial probiotic products for health is really good for you?
The European Food Safety Authority believes that so far there is no evidence to support this claim. The agency spokesman said, EFSA rejected health claims about probiotics since 2009, all submitted.
The main reason is, in most cases, these microorganisms "lack of adequate characteristics", which means that species and strains is not clear, and this is for the manufacturer of a specific product is "essential" in.
The manufacturer claims, such as "healthy gut, increasing the overall well-being, enhance the body's resistance" and other effects, the expression vague and can not be scientific assessment.
Most importantly, many say the lack of support "sufficiently high quality human studies' evidence.
"Good" intestinal bacteria failed to meet
Last month, the University of London School of Pharmacy researchers for eight probiotic products (including five kinds of capsules or powder formulations and three liquid products) test results give the industry a fatal blow - bacteria contained in capsules and tablets have been killed by stomach acid in the stomach before did not reach the intestine. In contrast, the liquid product is considered to be a significant number of bacteria can successfully reach the intestine.
However, the researchers explained that they did not assess the efficacy of probiotics, but only for the bacteria to the intestinal tract can be detected. "After that, who knows what will happen?"
Taking the pills will not help
Having said that, people buy and use such evidence has not been officially recognized support and hopes to get health benefits on a vaguely defined, just a waste of money it?
Gut-associated disease experts Royal Liverpool University Hospital Jonathan? Professor Rhodes said, "the complex relationship between intestinal bacteria and health is gaining recognition, changing gut bacteria may have an impact on health."
He pointed out that so far only been shown to alleviate the probiotic effect in a very few specific cases.
Recent large-scale systems analysis study published in the journal PLOS ONE by Canadian scientists completed 84 studies involving more than 10,000 test results of international patients.
Conclusion: "In general, probiotics beneficial to the prevention and treatment of gastrointestinal diseases."
But the problem is that only certain bacteria, for a handful of very specific diseases, such as Clostridium difficile infection and strong (broad spectrum) antibiotics cause diarrhea flora disturbance caused to have an impact.
For the average person, "just in case" based probiotic products can not get much benefit.
University of Aberdeen, Nutrition and Health Research Institute microbiologist warned that "If you are healthy, probiotic products is unlikely to cause you any harm, but in some cases, may even be some benefits, For example, you use a broad-spectrum antibiotics, however, if you have unhealthy - especially if you have some kind of gastrointestinal inflammation - which may mean the risk that probiotics might make you worse, not better, "he in 2008. He presided over the completion of a study on thrown a famous view: "in any case the use of probiotics is not desirable."
Acute test in patients with a group of Dutch researchers conducted pancreatitis, trying to study probiotics can prevent patients frequently suffer from this deadly infection. As a result, after giving 6 strain mixtures thereof "flawless reputation probiotic", 16% of the patients died, while the control group mortality rate was 9%.
Probiotic products is somewhat similar to vitamin supplements, eating a normal healthy person can get enough vitamins through diet, by completely without supplements to add extra.
Probiotics is the same - if you are healthy, that is to say there is no evidence to prove your intestinal flora imbalance, then you probably do not need probiotics.
Scientists differences
In general, probiotics within the industry scientists insist there is sufficient evidence to support their claims about the health benefits of probiotics, the European Food Safety Authority refused to approve these applications is not justified.
And more independent scientists not agree.
Under what circumstances probiotics effective
Swallow billions of bacteria has been confirmed in very rare cases can be helpful, these mainly related to intestinal health, including pouchitis, Helicobacter pylori infection, powerful antibiotic associated C. difficile infection and diarrhea taking .
King's College London Hospital researchers gave 186 cases of patients taking what is called Symprove liquid probiotic drinks, after 12 weeks of treatment compared with placebo, it reduces the level of pain the patient. The study, published earlier this year in the "digestive Pharmacology and Therapeutics" magazine.
In summary, for healthy people, taking the probiotic product does not provide additional health many products of bacteria does not reach the only probiotic flora rare cases can help.
