Abstract

Food allergy is a serious food safety and public health issue. However, the medical interventions for allergy treatment are still suboptimal. Recently, the gut microbiome–immune axis has been considered as a promising target to reduce the symptoms of food allergy. In this study, we explore the oral administration of lotus-seed resistant starch as a means to protect against food allergy using an ovalbumin (OVA) sensitization and challenge rodent model. The results obtained showed that lotus-seed resistant starch intervention alleviated the food allergy symptoms (such as reductions in body temperature and allergic diarrhea). Furthermore, lotus-seed resistant starch also attenuated the increase in OVA-specific immunoglobulins and improved Th1/Th2 imbalance in OVA-sensitized mice. These anti-allergic effects might be associated with the actions of lotus-seed resistant starch on intestinal microbiota. Taken together, our findings suggest that daily ingestion of lotus-seed resistant starch might be effective for the alleviation of food allergy.
