Several new studies suggest that dietary fiber could play a role in food allergies.
This notion is based on the idea that bacteria in the gut have the enzymes needed to digest dietary fiber, and when these bacteria break down fiber, they produce substances that help to prevent an allergic response to foods, said Charles Mackay, an immunologist at Monash University in Melbourne, Australia.
So far, the research related to this idea has been done mainly in mice, and dietary factors are unlikely to be the sole explanation for why allergy rates have skyrocketed, researchers say. But if the results were to be replicated in human studies, they would suggest that promoting the growth of good gut bacteria could be one way to protect against, and possibly even reverse, certain allergies, researchers say.
