you will be fond of to be propagated as a panacea for the intestines – and now far beyond him: probiotics to result in the non-medication products, the sales charts of the pharmacies. What you bring really, is, since, controversial. Meanwhile, findings show that these bacterial preparations can sometimes even be counterproductive or harmful piling up.
lactic acid producers
For some time now, studies and property, plant and seem to be increasingly books, the the solution of important health problems – the tendency to obesity, a weakened or misguided immune system to brain and depression – in the human intestines home. More precisely, flora said in the bowel. There are more bacteria than human cells in the body. They do not help there only to digest the food. The findings that they are also made from the heart to the brain is important for the health, piling up anyway. However, Stress, illnesses and medications can damage you. In abdominal rumbling, diarrhoea or after antibiotic therapies for many to grasp, therefore, is often anything but cheap probiotics.
There are usually Cocktails from viable micro-organisms – often mixtures of bacteria, such as lactobacilli and bifidobacteria. As a capsule or powder, you can buy them in drugstores or pharmacies. The additional bacteria to strengthen the immune system and the damaged intestinal flora back into balance. “It is attractive, Because I can do something Good for me,” says Britta Siegmund, Director of the clinic for gastroenterology at the Charité.
disappeared without a Trace in the intestines
pharmacist and many Doctors to advise patients. And in fact, accumulate evidence, and what the gut bacteria play important roles, constantly. However, Evidence that probiotics are helpful, straightforward and to the intestine or the total health, it is less reliable. Although many of the research evidence have been found. However, the studies have mostly been with a few volunteers carried out, differ greatly in study design, and are often funded by probiotics manufacturers.
Currently, says Siegmund, multiply more of the results that make skeptical. A study of the immuno Eran Elinav and his colleagues at Israel’s Weizmann Institute, which appeared in September in the journal “Cell” (PDF) lied about a sustainable effect in the intestine to doubt. The researchers had 15 healthy subjects over four weeks, probiotics, oral, and to examine their gut flora. The added bacteria left behind in about half of the Tested, no traces. Despite the low number of test Subjects, the result indicates that some people may simply be resistant to probiotics.
is not to stimulate The immune system to always be good
“The intestinal flora of every human being is unique,” explained Andreas Sturm, head of the Department of Internal medicine at the DRK-Kliniken Berlin Westend. The specialist for the treatment of intestinal disorders says: “The Microbiome is influenced by our genetics, by what we eat and where we live.” An interference in the intestinal flora is also always an intervention in the immune system. This can, but need not necessarily have positive consequences, and negative are possible. Effects estimate is difficult, so storm.
A medical reason for taking probiotics, to the doctors, so far, some were able to, was her gift to antibiotic therapy. As the bacteria killers do not only kill the cause of the neck pain and the blood poisoning, but also inhabitants of the Intestines. The renowned Cochrane Collaboration, an international network of Doctors and scientists, here. She explained to 2017, according to evaluation of numerous studies, there is at least “moderate” evidence of effectiveness.
Braking probiotics
A study by the Weizmann Institute, an unexpected result but. 21 test persons were treated, after they had taken antibiotics, in different ways: One group received probiotics, the other not, got the third your own Microbiome back transplanted. The latter achieved the best results, but is relatively expensive. In patients in the probiotics group populated the bacteria in the intestine. Surprisingly, it took but a few months longer, until it had built up its own intestinal flora again, as in the comparison group without the therapy. Probiotics delayed in the case of this small number of test Subjects so the Regeneration of the intestinal flora, rather than speed up. So they could “cause certain people a displacement of the natural colonization,” says storm.
And in the case of serious infections, additional bacteria may be even dangerous. In a study conducted in several Dutch hospitals in 2008, 15 patients who suffered from an acute inflammation of the pancreas had died, after taking additional intestinal bacteria, significantly more than the comparison group. The cause could have been that strong inflammation of the intestinal wall is permeable. It can then happen that the bacteria that should actually support the intestinal flora, do not enter the blood stream, where they were never meant to be.
Where is the Use of a Hand
A fundamental Problem is that it is very difficult to investigate the effect of probiotics in standardized study situations. In addition, the composition of the bacteria and the amount of “from manufacturer to manufacturer are different,” explains storm. Often too many microbes in the powder of a bag. And very many people take apparently probiotics, although they have no serious complaints. Whether you use them or maybe even damage, is hardly to assess. Under the supervision of a doctor or even in the context of a study, this happens almost never.
of course, the Benefit demonstrated, however for manufacturers and retailers. “Probiotics are currently a Lifestyle product,” says Charité-gastro-entero-login Siegmund. And a million-dollar business. According to studies by the market research company Insight Health 2017 were implemented in pharmacies in Germany alone, 140 million euros, with probiotic products, around 60 million euros more than in 2015. Companies that invested in a timely manner, to success stories. The Austrian family-owned company Allergosan about began about 25 years ago in a Graz-based pharmacy and developed probiotic supplements. Now it employs over a hundred employees. The sales figures of the “OmniBiotic”-the company’s products increased in 2015 and 2016, respectively, to around 50 percent. It is even sold with a bacteria mixture in order to facilitate a reduction in weight, thanks to the supposedly slender microbes do.
