Abstract: The prevalence of food allergy is rising and non-genetic factors such as diet have attracted close attention. The intake of high-fiber diets may induce oral tolerance and reduce the incidence of food allergy by interacting with the intestinal microbiota and modulating the intestinal mucosal immunity. This review describes the current status of studies on the interactions among dietary fibers, the gut microbiota and food allergy, with a focus on how dietary fiber affects the onset of food allergy by regulating the gut microbiota. The purpose of this article is to provide scientific information for developing reasonable diets for allergy sufferers and dietary fiber foods with the potential to alleviate food allergy.

Key words: food allergy; dietary fiber; gut microbiota; short-chain fatty acids
