My 12 year old son has been having stomach problems for some time - an upset stomach after a lot of things he eats. I haven't been taking too much notice (I remember my nephew having similar and loads of not very nice tests done and then he outgrew it and I was trying to avoid it). That is his only problem. Firstly, could this be a problem with gluten and secondly as presumably the next step is to cut out gluten, any suggestions of the better gluten free foods? Finally, should we just cut out all gluten and wait for an improvement or go to a doctor first?
