New research suggests a link between the use of antibiotics in early childhood and the development of food allergies. But before you freak out, there’s good news- this research also shows that there may be a new way to treat these allergies!
Over a decade ago, researchers found links between antibiotic use and increased allergies and asthma. It was speculated that antibiotics kill normal gut microbes, prompting allergic responses. Those microbes help your immune system recognize the difference between harmless and hurtful molecules that make their way into your body. When this microbe balance is disturbed, it’s possible that the body can react to harmless molecules in such a way as to cause an allergic response. This was observed in laboratory mice, and new research shows that the mice provided helpful clues in understanding this problem in humans.
In recently published research, scientists documented this link in children. They also identified a particular gut bacteria, Clostridia, that is important in preventing people from developing food allergies. When young mice were given antibiotics, researchers found that they were more likely to develop allergies to peanuts. But when Clostridia was given to the mice after their antibiotic regimen, their peanut sensitivity went away.
This research is important because it helps further our understanding of the balance of microbia in the intestinal system and its relation to allergy development. Food allergies are becoming more and more common. It’s estimated approximately 1 in 13 children suffer from a food allergy. Could probiotic treatments help children overcome allergies? There’s still research to be done, but this is a promising development!
