The Link Between C-Sections and Food Allergies

In the babies who were born by a vaginal birth, 11% had a food allergy. That's seemingly going against the grain of previous studies that said there was a link between C-section and having food allergies. The hypothesis that could explain the link between how babies are born and developing an allergy is called the microbial exposure hypothesis. And this suggests that a lack of exposure to a variety of microbes in early life can influence the developing immune system and predisposed it to an allergic phenotype.
