The Health Benefits of a Different Microbiota
More specifically, a study published in the Frontiers in Immunology journal in 2019 compared the gut microbiota of rural Amish infants with that of young children raised in urban environments. The main takeaway? Amish infants had a greater richness and variety of bacterial species in their gut microbiota. By living on farms, children from Amish communities are exposed early on to a host of microorganisms that colonize their intestinal tract, in part because of their closeness with farm animals.
Given that gut microorganisms directly influence gastrointestinal immunity, a diverse population could prove beneficial for children’s health.
An Impact that Begins in Early Childhood
In addition, a study published in 2023 in the European* Journal of Allergy and Clinical Immunology* found that there is a window of opportunity during early childhood when exposure to different environmental factors, such as time spent outside or with animals, plays a critical role in the development of the immune system.
By studying children with infantile eczema, the researchers discovered how the immune system of children living in rural areas is better equipped to identify and respond to threats. This would mean children raised in the countryside have better immune regulation than their urban counterparts.
Of course, more studies are needed to draw clear conclusions about the relationship between environmental factors, gut bacteria and the development of a strong immune system, but signs are pointing to the benefits of being in contact with various animals during early childhood.
