The Full Answer

Even though corn flakes are made from corn, the standard versions — including Kellogg's Corn Flakes — contain "malt flavoring" derived from barley, which contains gluten. That makes the regular cereal unsafe for people with celiac disease.

This is one of the most common "gotchas" in gluten-free shopping: a corn or rice cereal that seems safe but is disqualified by a single barley-malt ingredient. Always read the ingredient list rather than assuming.

For a safe option, choose certified gluten-free corn flakes (Nature's Path makes a GF corn flakes) or other certified GF cereals that do not use malt flavoring.

Hidden Gluten Risks in Corn Flakes

Celiac Safety Glossary

Celiac disease
Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
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.
