How to Begin a Gluten-Free Diet
Foods to avoid:
Gluten is the elastic protein found in wheat, rye, and barley (including durum, einkorn, graham, semolina, bulgur wheat, spelt, farro, kamut, and triticale). Commercial oats may also contain gluten due to cross contamination in processing (see more on gluten-free oats below).
Recipes that use wheat flour (bleached white flour, whole wheat flour, cracked wheat, wheat bran, barley flour, semolina, durum, spelt, farro, kamut, triticale) or vital wheat gluten are not gluten-free.
Semolina, durum, spelt and whole wheat pasta, including cous cous, ramen noodles, and some soba noodles, are not gluten-free.
Beer, ale and lager are not gluten-free. Foods cooked in beer- such as brats, meats and sausage, etc- are not gluten-free.
Malt vinegar, malt flavorings and barley malt are not gluten-free.
Recipes calling for breadcrumbs, breaded coatings, fried onion rings, flour dredging, bread and flat bread, croutons, bagels, croissants, flour tortillas, pizza crust, graham crackers, granola, cereal, wheat germ, wheat berries, cookie crumbs, pancake mix, pie crust pastry, crackers, pretzels, toast, flour tortillas, sandwich wraps and lavash, or pita bread are not gluten-free.
The vegan protein sub seitan (made with vital wheat gluten) is not gluten-free; and some tempeh is not gluten-free (you must check). Flavored tofu may or may not be gluten-free due to seasoning. Injera bread (traditionally made from teff flour) and Asian rice wraps may be gluten-free, but are not necessarily gluten-free (check labels, always).
Barley enzymes used in malt (and some "natural flavors") are not gluten-free (check all non-dairy beverages, chocolate chips, coffee, teas, dessert syrups, brown rice syrup.
Hidden gluten can be found in soy sauce, tamari style stir-fry sauces, marinades, gravy, gravy mixes and gravy packets, broth and bouillon, cooking sauces and instant soups, salad dressings, cured meats, sausage, hot dogs, vegan hot dogs and "fake" meat, sausages and burgers, self-basting poultry, flavored and herb cheeses. Watch for spice blends including curry powder, dry mustard (often combined with flour).
Read labels on canned and prepared soups, tomato paste, sweeteners, confectioner's powdered sugar and brown sugar, prepared beverages, flavored and instant coffees, herbal teas (watch for barley), roasted, flavored or spiced nuts, jerky, flavored yogurts, puddings and ice creams, chocolate and chocolate chips, cocoa powder and instant cocoa mixes, flavored vinegars (avoid malt vinegar, and fake "balsamic" flavored vinegar), cooking wines, flavored liqueur and liquor, wine coolers (malt).
Always read labels. Call the manufacturer.
Eating out is very risky. Be aware that delis and restaurants often add flour or pancake mix to egg omelettes, and use breadcrumbs to add body to tuna salad. Gluten-free pasta might be boiled in the same water used for standard pasta (and some kitchens blanch veggies in their pasta water). Avoid French fries and fried foods fried in the same oil with glutenous breaded foods (fried onion rings, batter coated fish, veggies, meat and chicken).

*Safe if milled in a dedicated GF facility/source. Check with companies to determine if they are using allergen safety protocols, and a gluten-free facility.

About baking GF recipes:
When it comes to converting your favorite baking recipes to gluten-free, a simple one-to-one flour substitution will not yield the same results as your recipe based on wheat flour.
Gluten is a giving, stretchy ingredient that supports rise, structure, texture and kneadablity. It takes more than a single gluten-free flour replacement to make a cake, bread, muffin or cookie recipe work. A combination of gluten-free flours and starches with some extra egg whites or leavening, and xanthan gum added to improve viscosity is necessary for optimum results.
