What happens when you live too clean

Scientists point out that the lifestyle is too clean to change the bacteria inside the body and easily lead to allergies, asthma, type 1 diabetes.

Today people live much cleaner than their ancestors thanks to sanitation, water purification and the support of soap, detergent, antibacterial and disinfection products. In short, we have less contact with bacteria than before. For a long time, experts supporting "hygiene theory" believe that a clean lifestyle changes bacteria inside the body , increasing the risk of allergies, asthma or other problems related to the immune system. Translate. Now, the work of the American author group published in the Cell magazine provides more evidence that "hygiene theory" is correct.

According to Times, the research team led by Tommie Vatanen from MIT's Broad Institute and Harvard compared the living environment of Russian, Finnish and Estonian children and found that there were differences in contact bacteria between these three groups. Specifically, Russian children have a lot of contact with E.Coli or Bifidobacterium species, while Finnish children have much contact with Bacteroides. Estonian children are exposed to all of these types because the area is moving away from agricultural to urban lifestyles.

"We know that Russian children live near the countryside, so they are more exposed to bacteria in the soil and from animals," said Ramnik Xavier from the Broad Institute of the author's group. "Finnish children live in super clean environments and spend most of their time inside solid houses." From the differences in bacteria, the authors found a link to type 1 diabetes: Finnish children are more susceptible to disease than Russian children.

Many other works confirmed contact with bacteria in the soil in particular and rural environment in general promote the production of fatty acids, against pathogens causing respiratory infection problems and affect too metabolism.The bacteria will "teach" the immune system to protect children from allergies and metabolic disorders such as diabetes.

Vatenan and his colleagues continue to study intestinal bacteria in the hope of finding the exact type and dose of bacteria that help control, even prevent type 1 diabetes and allergies.
