A new study from Yale School of Medicine has uncovered a link between skin injuries and the development of food allergies. In mice, researchers found that when a new food was introduced into the gut at the same time as a skin injury, such as a cut or even sunburn, the animals developed food allergies to that food. This connection may explain why children with chronic skin conditions like eczema are three times more likely to have food allergies, with skin inflammation sometimes preceding allergic disease.
The findings suggest that the immune system may “remember” foods introduced during times of skin damage as dangerous, even though the gut is normally tolerant to new foods. This challenges the notion that allergens must enter the body directly through broken skin, suggesting instead that signals between the skin and gut may drive allergic responses.
