Although corn, like wheat, rye and barley, does have a protein content it does not cause harmful effects to the intestines of someone with celiac disease. Therefore, it is considered safe for celiacs to eat from a gluten perspective.

Corn, or maize as the plant is called, is the largest cereal grain and is native to the Americas.
The grain can be eaten as a vegetable, known as corn on the cob or sweetcorn, as well as being ground into flour or meal. Corn on the cob has a medium Glycemic index (GI) of 55 whereas once processed into cornmeal the GI goes up to 69 - something to keep in mind if you also suffer from diabetes as well as celiac disease.
