Foods with gluten are foods made from wheat, barley, rye or triticale, a cross between wheat and rye. That covers obvious items such as bread, pasta, crackers, cakes and beer, but gluten also turns up in places most people would not guess, from soy sauce to salad dressing to some candy. This guide gives a gluten foods list by food group based on NIDDK and the Celiac Disease Foundation, explains the hidden sources of gluten, and shows how FDA gluten-free labels work. It is written for people who need to avoid gluten for a medical reason, such as celiac disease or a wheat allergy, and their families.
Peptide Labs does not sell gluten-free foods. This article is general nutrition information, not medical advice.
Key Takeaways
- Gluten is a protein found naturally in wheat, barley and rye, per NIDDK; triticale also contains it.
- All wheat types count, including durum, semolina, spelt, emmer, farro, farina, graham and khorasan.
- Hidden sources include traditional soy sauce, malt, some sauces, soups, candy, lunch meats and seasoned snacks.
- An FDA gluten-free label means less than 20 parts per million gluten.
- Do not cut out gluten before celiac testing; NIDDK says it can affect the results.
Foods with gluten: the grains to know
NIDDK lists the grains that contain gluten: wheat and types of wheat such as durum, emmer, semolina and spelt; barley, which may appear as malt, malt extract, malt vinegar or brewer’s yeast; rye; and triticale. The Celiac Disease Foundation adds wheatberries, farina, farro, graham and KAMUT khorasan wheat to the wheat family. Ancient or heritage wheats are still wheat, so our guides to farro, bulgur and couscous all cover gluten, as does our barley guide. Any food made from these grains contains gluten unless the gluten has been removed and the food is labeled gluten-free, which includes whole wheat flour and rye bread.
Gluten foods list by food group
| Food group | Common foods with gluten | What to check |
|---|---|---|
| Breads and pastries | Bagels, pita, naan, croissants, rolls, muffins, donuts, flatbreads, cornbread, potato bread | Cornbread and potato bread usually contain wheat flour too |
| Pasta and noodles | Pasta, ravioli, dumplings, gnocchi, couscous, ramen, udon, chow mein, egg noodles | Soba is often only part buckwheat, with wheat flour added |
| Crackers and baked goods | Pretzels, graham crackers, cakes, cookies, pie crusts, brownies | Gluten-free versions must say gluten-free |
| Cereal and granola | Wheat cereals, corn flakes or rice puffs with malt, granola with regular oats | Malt extract or malt flavoring means barley |
| Coatings and stuffings | Breadcrumbs, panko, breaded meats and fish, croutons, stuffing | French fries and fried snacks are on the check-the-label list |
| Sauces and gravies | Traditional soy sauce, roux-based cream sauces, many gravies | Wheat flour is a common thickener |
| Drinks | Beer and malt beverages | Only beer labeled gluten-free is an exception |
| Tortillas | Flour tortillas | Check corn tortillas for a gluten-free label too |
Hidden sources of gluten
The hard part is not bread; it is processed foods where gluten plays a supporting role. NIDDK says gluten may be found in candy, condiments, hot dogs and sausages, ice cream, salad dressing and soups, and that many ingredients and additives, such as colorings, flavorings, starches and thickeners, are made from grains that contain gluten. The Celiac Disease Foundation lists these hidden sources of gluten to check every time:
- Soy sauce: traditional soy sauce is brewed with wheat.
- Malt: malt extract, malt syrup, malt flavoring and malt vinegar come from barley, and brewer’s yeast is a barley product per NIDDK.
- Snacks: potato chips, French fries, energy bars and granola bars can include wheat or malt in seasonings or coatings.
- Meats: processed lunch meats, sausages, hot dogs and self-basting poultry.
- Soups, dressings and marinades: often thickened or flavored with wheat.
- Sweeteners and candy: brown rice syrup and some candy bars.
- Meat substitutes: seitan is made from wheat gluten itself.
Some ingredients sound unrelated to wheat but are made from it, and some wheat-derived ingredients are processed so heavily that the food can still qualify as gluten-free. Our maltodextrin guide explains how that common additive is made, and our wheatgrass guide covers the gluten question for wheat grass powders. When in doubt, the label and the manufacturer are the authority.
How to read labels for gluten
Two federal rules matter. First, wheat is one of the nine major food allergens, so packaged foods that contain wheat must say so, either in the ingredient list or in a Contains statement. Barley and rye are not major allergens, so they will not appear in a Contains statement; you have to read the ingredient list itself for barley, rye, malt and brewer’s yeast.
Second, the FDA gluten-free rule (21 CFR 101.91) says a food labeled gluten-free, no gluten, free of gluten or without gluten must have less than 20 parts per million of gluten. It cannot contain a gluten grain such as spelt or an unprocessed ingredient such as wheat flour. It may contain an ingredient like wheat starch that has been processed to remove gluten, as long as the finished food stays under the limit. If such a food lists wheat, the word must be followed by an asterisk explaining that the wheat was processed to meet FDA gluten-free requirements.
A real label example: Benefiber chewable fiber tablets use wheat dextrin as the fiber, the label says the product contains wheat, and the package is also labeled gluten-free. Our Metamucil vs Benefiber comparison explains the difference between the two fiber sources. A wheat-derived ingredient in a gluten-free product is not the same thing as safe for a wheat allergy, so people with an allergy should ask their allergist.
Cross-contact and naturally gluten-free grains
NIDDK warns that cross-contact happens when gluten-free foods touch foods or surfaces that contain gluten, which can make them unsafe for people with celiac disease. Grains are a common example. A 2010 pilot study found that 7 of 22 naturally gluten-free grains, seeds and flours sold without a gluten-free label had gluten at or above 20 parts per million, the FDA limit. That is why people with celiac disease are usually told to look for a gluten-free label even on grains that do not contain gluten themselves.
Oats are the classic case. NIDDK says research suggests most people with celiac disease can safely eat moderate amounts of oats, and that the oats should be gluten-free; see our oats guide and oat milk guide. Grains that do not contain gluten include quinoa, buckwheat, millet, sorghum, teff and amaranth; each guide covers its own gluten and cross-contact details.
Who needs to avoid gluten
NIDDK describes celiac disease as a chronic digestive and immune disorder that damages the small intestine, affecting an estimated 2 million people in the United States. People with celiac disease need to remove gluten from their diet, and NIDDK notes that a doctor or registered dietitian can guide them. A wheat allergy is a different condition handled by an allergist. Non-celiac gluten sensitivity can cause symptoms such as abdominal pain and tiredness, but NIDDK says it does not damage the small intestine.
This list is a reference for people with a diagnosed need, not a reason for everyone to cut out gluten. If you suspect a problem, see your clinician first: NIDDK says doctors do not recommend starting a gluten-free diet before celiac testing because it can affect the results. Wheat and rye also contain fructans, a type of FODMAP, which is a separate issue covered in our low FODMAP guide, and our elimination diet guide explains why food testing should be supervised.
Frequently Asked Questions
What foods contain gluten?
Foods made from wheat, barley, rye or triticale: bread, pasta, crackers, baked goods, many cereals, breaded foods, flour tortillas, beer and many sauces and gravies.
What are the most common hidden sources of gluten?
Traditional soy sauce, malt ingredients, salad dressings, soups, gravies, processed meats, seasoned chips and fries, candy and seitan, per NIDDK and the Celiac Disease Foundation.
Does gluten-free mean zero gluten?
No. Under the FDA rule it means less than 20 parts per million of gluten, and any unavoidable gluten must stay below that limit.
Why is barley not listed in the Contains statement?
Only the nine major allergens, including wheat, must be called out there. Barley, rye and malt appear only in the ingredient list.
Are oats a food with gluten?
Oats do not contain gluten themselves, but they are often cross-contacted with wheat. NIDDK advises people with celiac disease to choose oats labeled gluten-free.
Should I stop eating gluten to see if I feel better?
Talk to your clinician first. NIDDK says going gluten-free before celiac testing can affect the results.
