Thinking about this a bit more, I think there's a worthwhile analogy that helps here? I have been personally annoyed in the past, sometimes, by people who try to go gluten free despite not having a health problem. If your body *can* tolerate wheat, it can be a pretty load-bearing part of a healthy diet! People have been eating bread for millennia. If you avoid it for no reason, that can actually be *less* healthy, and it's frustrating to see people use it as a token for smugness, like when I was growing up and people operated on different levels of strictness re Ellen G. White's Health Message.

But in the end, the massive demand for gluten-free products, however individually misguided, made life a lot easier for people like me, with actual medical sensitivities. The posers are probably why I can buy Schar loaves at a normal grocery store at non-excruciating prices.
