Sorry, but that's not how it works. If your doctor thinks that, find another one.
Celiac disease is a genetic autoimmune condition that is not caused by anything you eat. However, a reaction to gluten is a serious effect of the disease. If you don't have the genetic defect (less than one percent of the population do), you can eat all the gluten you want. There is some non-gluten wheat sensitivity that affects less than another percent of the population, more of a food allergy.
All the folks belonging to the other 98% who think they live healthier or feel better if they cut out gluten are suffering from IGS (Imaginary Gluten Syndrome).
However, that's not necessarily a bad thing. We Americans tend to eat wheat (that is, gluten), in the worst possible combinations with the real killers, salt, sugar, and fat. Think pizza dough, hamburger and hot dog buns, pastries, donuts ... So anyone cutting down on that stuff, even for a scientifically nonsensical reason, will inevitably eat healthier and live better
