Corn is NOT a wheat, barley, or rye product. Despite being called a "grain," it belongs to a completely different botanical family and does not contain gluten proteins.
However, some corn products can be contaminated. Cornbread mixes often contain wheat flour. Corn chips may be fried in shared oil. Some corn tortillas are made on shared equipment. Always check labels on processed corn products and look for a GF certification.

Celiac Safety Glossary
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Gluten-free certification
- Gluten-free certification, such as the GFCO (Gluten-Free Certification Organization) seal, verifies that a product contains fewer than 10 parts per million (ppm) of gluten — stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
- Malt (Barley)
- Malt is fermented barley used as a flavoring or sweetener in cereals, chocolates, and beer; it is a major source of hidden gluten that is often overlooked on ingredient lists.
