Introduction to a Gluten-Free Diet
Individuals with gluten-related disordersmust avoid gluten for health reasons.This includes anyone diagnosed with celiac disease, non-celiac gluten sensitivity (NCGS), or dermatitis herpetiformis (DH), theskin condition related to celiac disease.Gluten is the generic name for certain types of proteins found inwheat, barley,andrye and their derivatives.
When individuals with celiac disease ingest gluten, an immune response occurs which damages the lining of the small intestine and can lead to symptoms and health problems in virtually all body systems. Even very small amounts of gluten can cause problems,whether or not obvious symptoms are present. In the case of non-celiac gluten sensitivity (NCGS),damage to the small intestinemay notoccur, but gluten must still be avoided.
The gluten-free diet should not be started before being properly diagnosed with a gluten-related disorder. Starting the diet without complete testing makes later diagnosis difficult. Tests to confirm celiac disease could be falsely negative if a person were on a gluten-free diet for a period of time. For a valid diagnosis to be made, gluten would need to be reintroduced for at least several weeks before testing.
Following a gluten-free diet is a major lifestyle modificationand can feel daunting, particularly for the newly diagnosed. There is a lot to know about foods, ingredients, and changes in lifestyle and cooking, and you may be wondering just where to start. Try taking things “one step at a time” to help make your gluten-free transition more manageable.
STEP1: Learn What Foods toInclude orAvoid
While the basis of a gluten-free diet is avoiding certain foods, you should also learn what foods are safe to eat.There are many naturally gluten-free foods you can still enjoythathappen to be delicious and healthy!Focus on shopping the perimeter of your grocery store: vegetables, fruits, fish, poultry, meats, anddairy productsaregood places to start.In their natural forms,without potentially gluten-containing flavorings or ingredients added, these foods are gluten-free andarestaplesof a gluten-free diet.
If you are going gluten-free,thesegluten-containinggrainsshould be eliminatedfromyourdiet:
- Wheat–Includes all varieties and forms such as: durum, spelt, semolina, couscous, bulgur, emmer, farina,farro, and einkorn.
- Barley
- Rye
Avoidvarieties andderivatives of thesethree grainsincluding:
- Triticale, a hybrid of wheat and rye
- Wheat starch that has not been processed toreducegluten to the levels that meet the definition of gluten-free
- Malt extract –derived from barley
- Malt vinegar– derived from barley
- Brewer’s yeast –usuallyderived from beerthat is brewed from wheat, barley,orrye(although can also be derived from sugar beets)
Choosenaturally gluten-free grains and flours,including rice, corn, soy, potato, tapioca, sorghum, quinoa, millet, buckwheat, cassava, coconut, arrowroot, amaranth, teff, flax, chia, yucca, bean flours, and nut flours.
What about oats?
What about oats? Research indicates that certified or labeled gluten-free oats consumed in moderation (up to ½ cup dry rolled oats daily) are tolerated by most people with celiac disease. See our article: Are Oats and Oat Flour Gluten-Free? The safest oat products are thosethathave been certified gluten-free. While products labeled gluten-free should comply with the FDA definition of containing no more than 20 ppm of gluten, this is not third-party verified. GFCO’s standard for gluten-free is 10 ppm of gluten or less.Consult with your physician or dietitian before adding oats to your gluten-free diet.
While distilled alcoholic beverages are gluten-free, most beers, ales, lagers, and malted beverages areNOT gluten-free because they aremade from gluten-containing grains. Beers made from gluten-free grains, such as sorghum, are gluten-free.Beers with “gluten-removed” on the label may not be gluten-freeandshould be avoided.Check out our article:Does Fermentation or Distillation Make a Product Gluten-Free?
STEP2:CarefullyReadFood Labels
An important part of successfully following a gluten-free diet is reading packaged food labels carefully. This includes “gluten-free” claims on packages, as well as product ingredient lists. Since ingredients can change at any time, it’s important to read labels every time you shop.
Look for a GFCO gluten-free Certification Mark
A productthatcarries athird-party gluten-free certification,such asGluten-Free Certification Organization (GFCO)’s mark, is considered safe for gluten-free consumers. If a product iscertified gluten-free,you can stop at this step.
Look for items labeled gluten-free
If a product is not certified gluten-free but bears a “gluten-free” claimand is regulated by the FDA,*it is considered safe to consume. The FDA gluten-free labeling regulation also applies to products labeled “no gluten,” “free of gluten,” or “without gluten”.
Check the list of ingredients
For productsthatare neither certified nor labeled gluten-free, it is essential to read the ingredient list.If any of the following are present on the ingredient list, the product is not gluten-free:
- Wheat ** (including all types of wheat such as spelt)
- Rye
- Barley
- Oats unlessthe oats or oat-containing products arecertified gluten-free
- Malt
- Brewer’s yeast
A product that is labeled gluten-free may include the term “wheat” in the ingredient list (e.g.,wheat starch) or in a separate “Contains wheat” statement, but the label must also include the following statement: “The wheat has been processed to allow this food to meet the Food and Drug Administration (FDA) requirements for gluten-free foods.”Read our statement on “Contains: Wheat.”
*FDA and USDA
The FDA gluten-free labeling regulation is a part of FALCPA (the “Food Allergen Labeling and Consumer Protection Act”). FALCPA applies to FDA-regulated products only. The FDA regulates the vast majority of packaged foods. The USDA regulates meats, poultry, egg products,and mixed products which generally contain more than 3% raw or 2% cooked meat (e.g.,some soups and frozen entrees). Products regulated by the USDA are not required to comply with FALCPA, but an estimated 80-90% do so voluntarily.
**Looking for wheat on ingredient labels
FALCPA requires that the top 8 allergens be clearly identified, wheat being one of them. Derivatives of wheat,such as “modified food starch,” must clearly indicate that “wheat” is the source when this is the case. If there is any doubt about whether a USDA regulated product is complying with FALCPA labeling, the following ingredients may be derived from wheat and need to be avoided or investigated: starch, food starch, modified food starch,anddextrin.

STEP 3: Explore Gluten-Free Goods
There are many gluten-free grains you may not have tried before, like sorghum, teff,and buckwheat (which is naturally gluten-free, despite its name). Often when some doors are closed, others are opened. Look at your gluten-free diet as an opportunity to discover new gluten-free foods and cuisines. Get inspired by Mexican and Indian spices and ingredients. Corn tortillas, salsas, guacamole,and beans are naturally gluten-free. Cook with traditional Indian ingredients like cumin, turmeric,and lentils.
Othernaturally gluten-free foodsare fruits and vegetables; fresh meats, poultry and fish; legumes, nuts and seeds, and plain dairy products. These foods in their pure forms are gluten-free. Processed or flavored versions may have gluten-containing ingredients.
Gluten-free substitutesfor foods commonly made with wheat are widely available at mainstream, international,andspecialtyfood stores, direct from gluten-free food manufacturers,and from websites.
Distilled alcoholic beverages, distilled vinegars, and wine may be safely included in the gluten-free diet.Read our article,“Does Fermentation or Distillation Make a Product Gluten-Free?”

STEP 4: Watch Out for Cross-Contact with Gluten
When preparing gluten-free foods,take careto prevent cross-contact with foods containing gluten. Cross-contact can occur if foods are prepared on common surfaces, or with utensils that are not thoroughly cleaned after preparing gluten-containing foods.
Using hard to clean equipment for both gluten-free and gluten-containing foods is one potential source of cross-contact. Toasters, strainers,and flour sifters should not be shared. Deep-fried foods cooked in oilthat arealso used to cook breaded products should be avoided.
Spreadable condiments in shared containers may also be a source of cross-contact. When a person dips into a condiment–suchas mustard, mayonnaise, jam, peanut butter,or margarine–asecond time with the knife used for spreading, the condiment becomes contaminated with crumbs and is not safe for consumption by individuals who cannot tolerate gluten. Consider using condiments in squeezecontainers,whenyou can,to prevent cross-contact.
Wheat flour can stay airborne for many hours in a bakery or at homeandland onexposed preparation surfaces,utensils,or uncovered gluten-free products, potentiallycausing a problem foranyone avoiding gluten.
