A large number of studies have examined and demonstrated the positive impact of a healthy gut flora. And again and again, researchers make new findings. One example is that the risk of developing asthma increases significantly if an infant lacks specific bacteria in the gut or if these have been destroyed during the first months of his or her life.
Researchers at the University of British Columbia in Vancouver discovered that the gut flora plays a role in a child’s likelihood of developing asthma. Using data from an extensive Canadian children’s health study, the scientists looked at the analysis of stool samples and determined the makeup of the participants’ gut flora at the age of three months and at one year old. Simultaneously, they recorded which of the children were most at risk from asthma or already suffered from asthma.
The result: Children who are highly at risk from asthma or which showed an allergic response to a skin prick test had much lower amounts of bacteria of the geni Lachnospira, Veillonella, Faecalibacterium and Rothia in their gut flora at the age of three months. This outcome is in line with findings in a number of other studies which showed that children are significantly more at risk from developing allergies if they grow up in a too-clean environment with few germs and bacteria.

This demonstrates the importance of the right bacteria in the gut and it implies that even more caution is advised when treating babies and infants with antibiotics, which should really only be given in case of bacterial infections.
