the problem with thee tests is that they are not actually that reliable-if you cannot tolerate wheat and you know and feel it then avoid it-the test shouldnt need you to have eaten wheat to test you as they use triggers in the test to find that out. maybe eat limited amounts of wheat and stick to wholegrain-less likely to upset your stomach. You shouldnt have introduced it so heavily and so suddenly back in your diet-you've put your boidy into shock by doing that. If a vegetrarian suddenly decided to introduce a lots of meat heavily in their diet theyd have problems too! do it slowly-maybe one wholmeal slice of bread in the morning and gradually increase. if eating wheat on an empty stomach in the morning really affects you-dont eat it
