<p>“This morning she had trouble after eating a plain bagel with honey.”
-She could have developed gluten intolerance, possibly? There are various digrees of it. I myself do not have severe reacitons, but I do not like the presence of wheat in my system, I just do not feel entirely comfortable with it, others have to jump into bathroom right away though. I would try to stay away from all food containing milk and gluten and see what happen. Stick to eggs, veggies, fruit, rice, meat, potatoes. I do not know what she likes. If some feel that it is hard to avoid milk / wheat, it is not that hard but it requires reading labels.</p>
