膳食纤维与肠道微生物互作调节食物过敏的研究进展

食物过敏的发病率逐步上升，遗传之外的影响因素如饮食受到密切关注。其中，高膳食纤维的食物摄入可能通过与肠道菌群互作和调节肠道黏膜免疫的方式来诱导口服耐受和降低食物过敏发生率。本文在阐述膳食纤维、肠道菌群和食物过敏三者的联系及研究现状的基础上，重点讨论膳食纤维通过调节肠道菌群影响食物过敏的发病机制，旨在为研究过敏人群的合理膳食及开发具有改善食物过敏体质的膳食纤维食品提供科学信息。

Dietary Fiber Regulates Food Allergy by Interacting with the Gut Microbiota: A Literature Review

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.
