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.
