Is cornmeal flour gluten free?

Yes, pure cornmeal is naturally 100% gluten-free. Cornmeal is created by grinding dried corn kernels into fine, medium, or coarse granules. Because corn is a naturally gluten-free grain, traditional cornmeal contains no gluten proteins.

It is widely used to make cornbread, corn tortillas, polenta, grits, and crispy coatings for fried foods. However, store-bought cornbread mixes often combine cornmeal with wheat flour for a lighter texture. Additionally, cross-contamination can occur if cornmeal is processed in commercial mills that also grind wheat. People with celiac disease should choose cornmeal products clearly marked with a certified gluten-free label.
