Purpose: This diet is designed to provide adequate nutrition while eliminating foods that contain gliadin, which is the alcohol-soluble extract of gluten, a protein found in barley, oats, rye, wheat, and wheat derivatives. The dietary guidelines below are intended for people with celiac sprue (also known variously as "celiac disease," "celiac syndrome," "gluten-induced enteropathy," "gluten-induced sprue," "idiopathic steatorrhea," and "nontropical sprue") and/or dermatitis herpetiformis (DH or Duhring's disease), for whom a gluten-free diet will help to prevent such complications as abdominal cramping and bloating, diarrhea, fatigue, excess intestinal gas, and weight loss. People with celiac sprue and/or DH must follow a gluten-free diet for life.
General Guidelines for a Gluten-Free Diet
If you are restricted to following a gluten-free diet, you must be careful in the selection of both the foods you prepare at home and the foods you buy and order when away from home. For preparing food at home you may find specialty cookbooks for a gluten-free diet helpful. Dietsite recommends Against the Grain: The Slightly Eccentric Guide to Living Well Without Gluten or Wheat, by Jax Peters Lowell; Wheat-Free Recipes & Menus: Delicious Dining Without Wheat or Gluten, by Carol Fenster, Ph.D; and More from the Gluten-Free Gourmet: Delicious Dining Without Wheat, by Betty Hagman. Remember that gluten-free products do not contain preservatives; be sure to store all gluten-free foods in your refrigerator or freezer.
For tips and information on reading food products' ingredient labels and on avoiding gluten when dining out, see the following sections. For detailed information on foods that do and do not contain gluten, refer to Foods for a Gluten-Free Diet
Reading Labels
If you must avoid gluten, you can still eat a variety of foods. In fact, by experimenting with a range of gluten-free products, you will be better able to provide your body with the nutrients it needs both safely and enjoyably. In addition to shopping for gluten-free products at your local supermarket or health-food store, you can order foods directly from the manufacturer or through the Gluten-Free Food Vendor Directory
However you choose to do your shopping, you will need to be very careful not only about reading food labels but also about verifying the ingredients of any medications you purchase. The tips and information below may be helpful:
- In addition to avoiding all foods that list barley, oats, rye, wheat, or wheat derivatives in the ingredients, avoid products containing gluten stabilizers, hydrolyzed vegetable protein (HVP), and texturized vegetable protein (TVP).
- Ingredients marked as additives, cereals and cereal grains, colorings, emulsifiers, excipients, flavorings, hydrolized plant protein (HPP), malts, preservatives, starches (including modified starch or modified food starch), vegetable gum, and vinegar may be derivatives of gluten-containing grains.
- If an ingredient list does not appear on a food product's label, contact the manufacturer for detailed information (the manufacturer's name and address must appear on the label). There are no laws requiring that a product label indicate the inclusion of food sources that contain gluten, and food manufacturers and processors may change a product's formula without announcement. When in doubt about the contents of any commercial product, do not use the product until you have obtained the necessary ingredient information from the manufacturer. Most food manufacturers will provide information about their products upon request.
- Before you take any medication, check with your pharmacist or the product manufacturer to make sure that the medication is gluten-free. All medications have fillers or dispersing agents, some of which may include wheat starch.
Dining Out
Restaurant menus almost never provide explicit information about the inclusion of gluten in dishes. If you must avoid gluten, order very carefully. Always ask your waiter to list the ingredients in dishes, and follow these guidelines:
- Ask your waiter specifically whether the dishes that you are interested in contain any of the following ingredients: barley, bran, bulgur, cereal additives or products, durham, emulsifiers, flour, graham, HVP or TVP, malt or malt flavoring, millet, oats, rye, starch (modified starch or modified food starch), wheat, wheat germ, vegetable gum.
- Inquire about the methods of preparation as well as about the foods themselves. Flour and cereal products that contain gluten are often used in the preparation of dishes. Order meat, poultry, or fish, for example, only if the dish is prepared without breading, gravy, or sauce.
- Beware of food that is grilled; a restaurant's grill may be contaminated with gluten from other foods.
- Beware of fried foods; the grease in which a restaurant fries food may be contaminated with gluten from other foods.
