GFClaremont Mom replied to David in Seattle's topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsI had a similar problem and I discovered that foods containing xanthan gum gave me the same symptoms as ingesting gluten. Almost all gluten-free salad dressings, sauces, and baked goods contain this ingredient. Guar Gum is sometimes used instead of xanthan gum and it doesn't cause any alergic reaction. Some products that I've tried and enjoyed: Betty Crocker Devil's Food Gluten Free Cake Mix, Mrs. Denson's Quinoa Macaroon Cookies, Mezzetta Napa Valley Bistro Artichoke Marinara and 505 Southwestern Chunky Salsa. Hope this helps you, I know how frustrating it can be...
