"Nobody turns "gluten-free" unless he has to." That's demonstrably untrue. The existence of non-Celiac gluten sensitivity is not demonstrated by science. It is a clear example of the "nocebo" effect. I know lots of people eating gluten free because they believe they have to...but, there's no reason to believe that's true. Specifically, the research team that first posited gluten sensitivity followed up with a more comprehensive study, and found: "On current evidence the existence of the entity of NCGS remains unsubstantiated". And, "Recent randomized controlled re-challenge trials have suggested that gluten may worsen gastrointestinal symptoms, but failed to confirm patients with self-perceived NCGS have specific gluten sensitivity."
