Read on the lable and if it says "wheat, barley, rye, flour, vinegar" it has gluten in it. It is also very common for people with Celiacs disease to also be lactose intollerant. Cut out all dairy and wheat products and see what happens. This will be a MAJOR life change for you. Baiscally you will be limited to fresh fruit and vegetables, beef, pork, chicken and fish. You can go to a health food store and purchase "gluten free" oatmeal, pancake mix and other items but they will cost you. The gluten free pasta and bread is NASTY! Dont wast your money on those items.
Items such as all bread, pasta, salad dressing, ketchup, milk, beer, cake, breakfast cereal, croutons, pop tarts and so on are no longer your friend. I would also stay away from peanuts, pecans, walnuts and other nuts just in case. It does not surprise me that your doctor never brought up Celiac as most doctors have never even heard of it.
Dont give up...I'm now at 1.5 months wtih this and still figuring out what I can eat. Even the smallest amount of gluten can set you off. Eating out is no longer an option for you unless you eat a grilled chicken salad and squeeze a lemon on top for taste. You can do this. Please keep me posted. If I find a new recipie I will let you know.
I cant believe I just said I would "swap" a recipie....that will cost me 10 "man points."
