Just discovered this thread. I've been on GF diet for over 30 years and it is very restorative to find others and learn from them. A big thank-you Kittylester. Like Whitewave I keep to gluten free to avoid migraines and as Merlotgran suggests for her GS I could not bear to go back to gluten for 6 weeks in order to take the tests. I have found all processed food difficult just as GracesGranMk2 writes. Over the years I have decided that sometimes it is due to wheat dust prevailing in the mill or processor. With others it is left in the oil for cooking or handling. Chinese restaurants used to be a problem because of MSG (a separate problem, glutamate is not gluten), or rice milled where gluten was left behind and similar. I stick to potatoes, sweet or ordinary, GF crisps and, fortunately can tolerate - and love - every vegetable, all salad stuff except when someone has added cous-cous or croutons! Keep the posts going (smile).
