A study by 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 by becoming adults. That means that "babies born vaginally, and are therefore exposed to maternal rectal bacteria have a reduced risk of asthma and allergies than those born by cesarean section, who are exposed to less variety of microorganisms to born ", concludes Hans Bisgaard, a researcher at Copenhagen University and coauthor of the study. According to Bisgaard and 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 it is ironic that the bacteria and dirt, considered a threat to our life now imposed as a key ingredient for a healthy life. In fact, previous studies suggest a connection between the intestinal flora and other diseases such as diabetes or obesity.
