Overview
About Corn
Corn is naturally gluten-free, so the common worry that it contains gluten is a myth, though corn products milled in wheat facilities can pick up gluten by cross-contact.
The real triggers are different: corn is high in free glutamates, the same savory compound behind MSG reactions, and moderately high in salicylates. It is also high in lectins and sits on the pro-inflammatory side, which is why some people feel bloated or headachy after corn even though it passes as a safe grain.

Watch for
What trips people up
- High in free glutamates, so it can provoke the same headaches or flushing that people blame on MSG
- Moderately high in salicylates, a trigger if you react to aspirin or salicylate-rich foods
- High in lectins, which can bother people who are sensitive to them
- Naturally gluten-free, but processed corn products can be cross-contaminated with wheat, so check labels if you have celiac disease

FAQ
Common questions about Corn
Does corn contain gluten?
No. Corn is a naturally gluten-free grain and safe for celiac disease on its own. Confusion comes from the term corn gluten, which is a marketing name for a corn protein and is not the wheat gluten that causes celiac reactions. The one real risk is cross-contact when corn is processed on shared equipment with wheat, so choose certified gluten-free corn products if you are strict.
Why does corn bother me if it is gluten-free?
Corn is high in free glutamates and moderately high in salicylates, and it is also high in lectins. Any of these can cause symptoms like bloating, headaches or flushing that have nothing to do with gluten, which is why some people react to corn while tolerating other gluten-free grains like rice.
