The Full Answer
Popcorn is made from corn, which is a naturally gluten-free grain. Plain popcorn — air-popped, stove-top, or microwaved — is safe for people with celiac disease.
The main concerns are flavored popcorn varieties that may contain malt flavoring, wheat-based seasonings, or soy sauce. Movie theater popcorn is generally safe (butter flavoring is typically GF), but check with the specific theater.
Microwave popcorn is also generally safe in its plain and butter varieties. Brands like Orville Redenbacher's and Pop Secret list most of their plain and butter varieties as gluten-free.
