Hi Matt, I would put the products that make her feel ill side by side and compare labels. See if there is any one ingredient in common like soy for example, a common intolerance. If soy or tapioca or whatever is in everything then try other products that do not have that ingredient. Another possibility is that the carb level is too high for her. Is she diabetic or borderline diabetic? Many of the gluten free foods are much higher in carbs than their 'everyday' counterparts.
Well, I looked at all the products, and the only real similarity is the Xanthem gum, but that's in other products that are not gluten-free as well, and don't make her feel ill then... She is also not diabetic. I really have no idea what to do for her. Could the carb levels still be too high for her even without her being diabetic? If so, what can I do for her? Thank you very much for your help thus far.
