Probiotics, useful bacteria, can alleviate the symptoms of hay fever, according to an online edition for girls and women from 14 to 35 years old Pannochka. net This is evidenced by the results of a review of several studies.

But doctors say that they are not yet able to explain the mechanism of action of probiotics in seasonal allergies.

Scientists have suggested many years ago that allergic diseases can be caused by a shortage of bacteria in the body due to too clean living conditions (excessive hygiene). Living in a clean environment means that our body does not face numerous microbes, to a meeting with which it was prepared by evolution. It is believed that this leads to disturbances in the functioning of the immune system, which can not find its natural satellite.

Researchers from the Medical Center of Vanderbilt University Medical Center in the United States analyzed 23 studies, which included a total of 1919 people. The quality of the studies varied, but two of them were randomized controlled trials (RCT), which are considered the gold standard for scientists.

The authors say that in 17 studies it was found that in people with seasonal allergy prolonged use of probiotics is associated with a decrease in the severity of symptoms and a better quality of life compared to those who took placebo instead of probiotics.

In 6 other studies, scientists failed to prove that probiotics affect the symptoms of hay fever. These results are reported in the new issue of the scientific journal International Forum of Allergy & Rhinology.

According to the researchers, the results look promising, but to confirm the effectiveness of probiotics, it is necessary to conduct more than one job. Nevertheless, given the harmlessness of probiotics, they recommend allergy sufferers to try this interesting option.
