Celiac disease is more common than you think. The National Institutes of Health estimates that as many as one in 141 Americans has celiac disease, with most not even knowing it. In addition, there are other digestive ailments that can make one sensitive to gluten.
The antigens that indicate the possibility of celiac disease occur in 1 in 110 tested blood samples. Of those, less than 1 in 10 have symptoms. No celiac gluten sensitivity has not been identified as a thing. Tests show that symptoms do not occur after people who complain they have it are given gluten, at least not within a defined period of observation. Yet in some metro areas, as many as fifteen percent of affluent white people claim they have it. These were the idiot I was bashing. To be clear: they report having gluten sensitivity, but show no symptoms after being given gluten tests.
