Researchers say modern society’s focus on hygiene may overprotect the human immune system, leading to more cases of inflammatory bowel disease. Dr. Gil Kaplan, a gastrointestinal specialist at the University of Calgary, said people no longer are exposed to bacteria that hundreds of years ago would “prime out the immune system properly.” He said without such exposure, it is more likely those with a genetic susceptibility to IBD will get the disease.
