Microbiota and Food Allergy

AbstractEmerging evidence suggests that the increasing prevalence of food allergies is associated with compositional and functional changes in our gut microbiota. Microbiota-host interactions play a key role in regulating the immune system. Development of a healthy gut microbiota and immune system occurs early in life and is largely shaped by exposure to maternal microbes through vaginal/natural delivery and breast milk, whereas use of antibiotics can disrupt gut homeostasis and significantly raise the risk of allergic diseases. Thus, changes in the quantity or diversity of gut microbes affect oral toleranace through interations of microbial molecules with pattern recognition receptors on immune cells and confer susceptibility to food allergies. On the other hand, short chain fatty acids w...
