Celiac.com 09/23/2020 - We get more than a few question about popcorn. Specifically, is popcorn gluten-free, and safe for people with celiac disease? The short answer is that, yes, popcorn is gluten-free. Corn is gluten-free. That means that plain popcorn, either air-popped, or cooked in oil, is gluten-free. It's still gluten-free if you add some butter and salt.

Beware of Gluten in Popcorn Seasonings

Unless wheat or gluten ingredients are added, popcorn is always gluten-free and safe for people with celiac disease. Watch out for seasonings, including any pre-mixed brands. Read labels carefully to avoid wheat or gluten in seasonings you may add to your popcorn.

Remember, any wheat or gluten should be declared on the allergen warning.

As always, please read labels carefully. When in doubt, check manufacturer websites.
