What foods contain gluten? Prepare yourself: The list is long! In fact, I split it up into three lists to make this information easier for you to absorb.

When purchasing processed or packaged foods, always check ingredient labels. In many cases, it is easy to determine what foods contain gluten because their ingredient label contains the word “wheat,” “barley,” or “rye.” However, hidden sources of gluten can be tricky.

When eating out, assume that the less-than-obvious foods in these lists contain gluten—unless proven otherwise.

The following are the three lists that describe what foods contain gluten, which you must avoid if you have celiac disease or non-celiac gluten sensitivity (often shortened to “gluten sensitivity“):

What Foods Contain Gluten: A List of Cereal Grains That Contain Gluten

Technically, all cereal grains contain some form of gluten. Yes, even corn and rice. And some people with celiac disease or gluten sensitivity need to avoid them as well. It all depends on which forms of gluten you are sensitive to.

But the traditional advice for celiacs and other gluten-sensitive people is to avoid wheat, barley, and rye (and sometimes oats because of potential cross-contamination with wheat).

If you are following the traditional gluten-free diet, the following list includes the grains to avoid.

Just be aware that if you aren't healing as expected on the traditional gluten-free diet, some medical detective work might be in order. You might, in fact, need to go beyond the traditional gluten-free diet, and avoid consuming the other “gluten-free“ grains (corn, oats, millet, rice, and sorghum) —at least temporarily.

  • Atta flour – A wheat-based flour used to make most South Asian flatbreads
  • Barley – Any ingredient that contains the word “barley” should be avoided, for example, barley grass, barley malt, barley syrup, and sprouted barley
  • Bulgur – A quick-cooking form of whole wheat, most commonly found in tabbouleh salad
  • Couscous – A tiny pasta made of wheat or barley that is considered a staple in North Africa
  • Dinkel – An ancient relative of wheat also known as spelt
  • Durham wheat – The hardest of all forms of wheat and has high gluten content, commonly found in pasta
  • Einkorn – Considered to be the oldest form of cultivated wheat, first grown over 10,000 years ago
  • Emmer – An ancient form of wheat originally domesticated in what is now southeast Turkey
  • Farina – A milled cereal grain typically made from wheat germ and the inner parts of wheat kernels, and most commonly served warm as a cereal food
  • Farro – Encompasses three varieties of ancient grains: einkorn, spelt, and emmer wheat
  • Graham flour – A form of whole wheat flour that is unrefined and unbleached, often used to make graham crackers and pie crusts
  • Groats – Hulled or crushed grain, especially oats, but possibly wheat or rye
  • Kamut – The trademarked brand of an ancient form of wheat called khorasan wheat
  • Maida – A finely milled, refined, and bleached wheat flour made from the endosperm of the grain (the starch component)
  • Mir – A cross between wheat and rye
  • Oats – On the traditional gluten-free diet, typically not considered a gluten-containing grain, but often cross-contaminated with wheat, rye, or barley (unless certified gluten free)
  • Rye – Typically used as a flour for making bread
  • Semolina – Made from durum wheat; if pasta has an ivory color approaching yellow, it is almost certainly made from durum semolina
  • Spelt – An ancient relative of wheat also known as dinkel
  • Wheat – Any ingredient that contains the word “wheat” should be avoided, for example, sprouted wheat, wheat berries, wheat bran, wheat germ, wheat grass, and wheat starch

On an ingredient label, you might see wheat, barley, and rye in their Latin names. They are: Triticum vulgare (wheat), Hordeum vulgare (barley), Secale cereale (rye), Triticale (a cross between wheat and rye), and Triticum spelta (spelt, a wheat variety).

Pseudo grains such as amaranth, buckwheat, and quinoa are not grains. Rather, they are the grain-like seeds of broad-leafed plants. Unfortunately, these pseudo grains are sometimes cross-contaminated with gluten. Some experts recommend avoiding them as well for people who have celiac disease or gluten sensitivity, but many don't.

If you are eating pseudo grains and not healing as expected, it might be worth doing some medical detective work and removing them from your diet—at least temporarily. It might be that the brand you are eating is contaminated with gluten, but a different brand would work for you.

Or, it might be that these pseudo grains are hard for you to digest because your gut needs more healing time. In that case, you could try reintroducing them into your diet later.
