A study from the University of Copenhagen (Denmark) reveals that the lower the number of bacteria that live in our intestines during childhood, the greater the risk of allergies when we become adults. This implies that "babies born by natural delivery, and therefore exposed to bacteria in the maternal rectum, have a lower risk of suffering from asthma and allergies than those born by cesarean section, who are exposed to less variety of microorganisms by to be born ?, concludes Hans Bisgaard, a researcher at the University of Copenhagen and co-author of the study.
According to Bisgaard and his colleagues, we must be in contact with a large number of different bacteria in the first months of life , when the immune system is developing and "learning." The researchers say that it is ironic that bacteria and dirt, considered a threat to our lives, are now imposed as a fundamental ingredient for a healthy life. In fact, there are previous studies that point to a connection between the intestinal flora and other diseases such as diabetes or obesity.
