Assumption: All human guts contain similar microbiota.
This study analyzed the gut microbiota of infants and determined that two factors significantly impacted the types of microbiota found. The factors were elective cesarean birth and ingestion of infant formula.
This study does not define any particular gut microbiota as “good” or “bad.” It simply states that the make-up is *different* in babies, depending on type of delivery and what they are fed. From here we can research how each of these microbes works and what we can do to keep our babies as healthy as possible. So, I don’t see this study as an endpoint, but as a beginning.
