> I wonder if this partly explains why so many people have "gluten intolerance" (many being self-diagnosed). It may not be something inherent to gluten, but rather the way wheat is grown and harvested. There's a class of carbohydrates called "FODMAP" (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) that are conjectured to be responsible for a lot of "gluten intolerance". There is some evidence that lower FODMAP intake reduces symptom severity in people with irritable bowel syndrome, and measures taken to cut gluten out of a diet can lead to dramatically lower FODMAP intake. So the basic idea is that a lot of people are successfully self-treating their undiagnosed IBS with a "gluten-free diet" and thus misattributing the problem to gluten.
