His children (my aunts and uncles) certainly do, although you wouldn't know it, because they all have diseases that can be tied to gluten allergies in one way or another, and yet they still eat it.
For my own part, I was raised on a wheat farm (!!) and spent my childhood running through the fields, shoveling the grain bins, and dusting the chaff off my clothing during harvest. It's only amazing I didn't start to feel the symptoms of GI a LOT sooner.
P.S. - The rice tortillas are the best. I would really have a hard time eating GF all the time if I had to give those up.
