Grits
Yes. Grits are made from corn and are naturally gluten-free, though check instant/flavored versions and watch for cross-contamination.
Watch out for:
- Instant/flavored grits may add wheat-based seasonings
- Shared equipment cross-contamination with wheat
- Restaurant add-ins (e.g., flour-thickened gravy)
Oatmeal
Pure oats are naturally gluten-free, but most oatmeal is contaminated with wheat during processing. Only buy certified gluten-free oatmeal.
Watch out for:
- Cross-contamination during farming and processing
- Avenin sensitivity in ~8% of celiacs
- Flavored oatmeal may contain malt or barley-based ingredients
