The quick answer is no, corn tortillas do not contain gluten. Corn tortillas are made from corn masa flour, which is naturally gluten-free. Gluten is a protein found in wheat, barley, and rye. For people with celiac disease or gluten sensitivity, corn tortillas are a safe gluten-free option.
What is gluten and why must some people avoid it?
Gluten is a protein found in grains like wheat, barley, and rye. It helps give elasticity to dough, allowing it to rise and keep its shape. Gluten is found in many bread and baked products.
For people with celiac disease, gluten triggers an autoimmune response that damages the small intestine. Even small amounts of gluten can cause symptoms like abdominal pain, bloating, diarrhea, vomiting, and fatigue. The only treatment for celiac disease is sticking to a strict lifelong gluten-free diet.
Some people without celiac disease have a gluten sensitivity or intolerance. For these people, gluten can cause uncomfortable gastrointestinal symptoms. A gluten-free diet helps manage these symptoms.
Are corn tortillas gluten-free?
Yes, corn tortillas do not contain any gluten. Here’s why:
- Corn tortillas are made from masa harina, which is a type of corn flour made from dried and ground corn that has been treated with limewater. This process is called nixtamalization.
- Corn does not contain gluten naturally. Therefore, corn-based products are inherently gluten-free.
- Masa harina is produced from 100% corn with no wheat, barley or rye added. Without these gluten-containing grains, the corn flour remains gluten-free.
- Reputable brands that produce corn tortillas follow gluten-free manufacturing protocols to avoid cross-contamination with gluten. They may be certified gluten-free by organizations like the Gluten-Free Certification Organization (GFCO).
So you can confidently eat corn tortillas on a gluten-free diet. Always check the label to confirm the product is certified gluten-free if you are highly sensitive.

Other Mexican gluten-free foods
Beyond corn tortillas, some other naturally gluten-free foods common in Mexican cuisine include:
- Corn chips
- Corn tamales
- Corn arepas
- Corn empanadas
- Corn gorditas
- Hominy (posole)
- Corn on the cob
- Fresh corn kernels
Most Mexican rice dishes are also gluten-free, as rice does not contain gluten. Other gluten-free proteins you may find in Mexican dishes include pork, chicken, beef, fish, shrimp, beans, lentils, and eggs.
What about flour tortillas?
While corn tortillas are gluten-free, flour tortillas are not. Flour tortillas are typically made from wheat flour, which contains gluten. So you’ll need to avoid these if you follow a gluten-free diet. Opt for corn or other gluten-free alternatives instead.
Risk of cross-contamination
While plain corn tortillas don’t contain gluten, there is a risk of cross-contamination during manufacturing. Trace amounts of gluten could make their way into the product if it’s produced in a facility that also handles wheat flour.
Those who are highly sensitive should look for brands that are certified gluten-free. These companies adhere to strict protocols and testing to ensure no cross-contamination occurs. Labels will clearly state the product is certified gluten-free.
You can also make your own fresh corn tortillas at home. This avoids any risk of cross-contamination from manufacturing. Simply mix masa harina with water and press into tortillas.
What about restaurants?
Plain corn tortillas served at restaurants should also be gluten-free. However, there is a higher risk of cross-contamination compared to packaged brands. Here are some tips for eating corn tortillas safely when dining out:
- Ask if the restaurant has a dedicated gluten-free menu
- Ensure the corn tortillas are not prepared alongside flour tortillas on the same surface
- Request corn tortillas freshly made rather than pre-packaged, if possible
- Avoid chips and fried foods, which may be cross-contaminated with flour-based breading
- Check that sauces and salsas are gluten-free
Let your server know about your gluten-free needs when ordering. Reputable restaurants trained on food allergies can make accommodations to prevent cross-contact.
