“Alternative medicine has embraced the concept of leaky gut syndrome, blaming it for nearly everything that can go wrong with a person,” says Alessio Fasano, director of the Center for Celiac Research and Treatment at Massachusetts General Hospital for Children. In contrast, “modern medicine disregards leaky gut syndrome as voodoo medicine because of claims that it causes so many problems when there is no evidence,” he notes. “In my opinion, both camps are wrong.”
