Duh, it's an intolerance to gluten PLUS to carbs in general. That's my whole point, though: on a restrictive alone diet, you FEEL BETTER, BUT GET WORSE. Reactions to food intake that violates the diet in the slightest get worse and worse, showing that the yeasts are still multiplying.
Maybe my example didn't quite make sense. Let's put it this way: a couple years of extremely carb-restrictive eating have led my body to be unable to tolerate 2 slices of pizza, where before, an ENTIRE pizza MIGHT mess with me, and might NOT.
