Scientists at Stanford University have uncovered a compelling link between gut bacteria and food allergies. Their study, published in Science Immunology, found that individuals with certain microbial imbalances were more prone to severe allergic reactions. By analyzing stool samples from children with and without food allergies, researchers identified specific bacterial strains that help regulate immune responses.
In a promising follow-up experiment, mice with depleted gut bacteria developed allergies, but symptoms improved after receiving microbiota transplants from healthy donors. These findings open the door to potential probiotic treatments that could prevent or reverse food allergies. While more human trials are needed, this research marks a significant step toward understanding how gut health influences allergic diseases.
