BBC – Future – What we do and don’t know about gut health
Our microbiomes start developing when we’re born, when microbes colonise the human gut. Babies delivered by natural birth have been found to have higher gut bacterial counts than those delivered by Caesarean section because of the contact they make with their mother’s vaginal and intestinal bacteria, says Lindsay Hall, microbiome research leader at Quadram Institute Bioscience.
“C-section-born infants miss out on that initial inoculation, and some of the microbes they come into contact with will be from the skin and environment” says Hall.

“This is very important for infants to develop their immune systems. Recent work has suggested that disturbances in early life gut microbiome have negative consequences for host health,” she says.
