It all began with the publication in the journal Clinical and Translational Gastroenterology. The scientists decided that probiotics can cause brain fog, it is a violation of intellectual activity. This could manifest as impaired memory or concentration difficulties. The researchers found that bacterial preparations from the pharmacy take up residence in the intestine and then produce a lot of lactic acid. From this develops acidosis, and the brain can be affected. And it may very well be that it is now necessary to prescribe probiotics as a prescription medication.
After that, the International Organization for probiotics rightly indignant and stated that the results of one study can not be extrapolated to the practice. of probiotics experts pointed out that all these mists in mind there are no clear criteria. Then it turned out that no one checked the level of lactic acid from the very people to study. Maybe they have previously been acidosis? No one checked whether the acidosis will be held if cancel probiotics. Well, a lot of different things that point to the poor quality of the study.
Defenders of beneficial bacteria thought of the thousands of other studies in which nothing was found shocking. They also pointed to a whole army of frightened consumers who trust their probiotics, and now try to discover the warning signs.
It is clear that the authors of the controversial study became famous. But it seems that the harm to public health will get more than the potential benefits.
