It is becoming more and more clear that our gut flora is the central issue for health. (More here on that)
It is best to start with the the healthiest gut flora possible. This means that it is best that we are born vaginally. We are a blank slate in the womb. Being born vaginally gives us our mother’s flora.
Evidence is now coming out about how important this is. Leaving mothers with a more informed choice. If you can have a vaginal birth, you are giving your child the best start possible.
The researchers found that infants born by cesarean delivery were lacking a specific group of bacteria found in infants delivered vaginally, even if they were breastfed. Infants strictly formula-fed, compared with babies that were exclusively or partially breastfed, also had significant differences in their gut bacteria.
“We want parents (and physicians) to realize that their decisions regarding c-section and breastfeeding can impact their infant’s gut microbiome, and this can have potentially lifelong effects on the child’s health,” says postdoctoral student and first author Meghan Azad, University of Alberta.
“The potential long-term consequences of decisions regarding mode of delivery and infant diet are not to be underestimated,” write the authors. “Infants born by cesarean delivery are at increased risk of asthma, obesity and type 1 diabetes, whereas breastfeeding is variably protective against these and other disorders.”
Beginning before birth, CHILD collects a range of information on environmental exposures such as pets, air pollution, household cleaning products, maternal and infant diet and more, and child health outcomes (including biological samples and clinical assessments). The researchers will use this information to study the development of the gut microbiome and its relationship to conditions such as wheeze and allergies in future studies.
“Children born by cesarean delivery or fed with formula may be at increased risk of a variety of conditions later in life; both processes alter the gut microbiota in healthy infants, which could be the mechanism for the increased risk,” writes Dr. Rob Knight, a Howard Hughes Medical Institute Early Career Scientist and an Associate Professor with the BioFrontiers Institute and Departments of Chemistry and Biochemistry and Computer Science, University of Colorado, Boulder, Colorado, United States, in a related commentary.
“These issues are of direct relevance to pregnant women and health practitioners and should be considered when choices such as elective cesarean delivery and other interventions are discussed,” state the commentary authors.
