Gut health linked to childhood allergies, study finds
A study published in Nature Communications suggests that childhood allergies, including eczema, hay fever, asthma, and food allergies, may be caused by disorders in the gut bacteria. Researchers found that all four conditions share a common cause, which is a breakdown in the ecosystem of bacteria, fungi, and archaea in the intestine, leading to compromised gut lining and heightened inflammation. The study also found that antibiotic usage in the first year of life increases the risk of later allergic disorders, while breastfeeding for the first six months is protective. Developing therapies that target gut bacteria interactions during infancy may prevent the development of childhood allergies.
