"Originally, I thought there was more celiac because we were better at finding it," said Dr. Joseph Murray, a gastroenterologist and professor of medicine at the Mayo Clinic. But he was mistaken. For a 2009 study in the journal Gastroenterology, Murray's research team compared blood samples collected from about 6,500 young men at a US Air Force base between 1948 and 1954 with a comparable number of modern-day samples. Today's young men, they found, tested positive for celiac at four and a half times the rate of their forebears.
