Is Popcorn Gluten Free?

Yes, plain popcorn is naturally gluten-free as it comes from corn, which is not a gluten-containing grain. However, some flavored popcorn products may contain gluten ingredients or be processed in facilities with gluten cross-contamination, so it’s important to check labels if you have celiac disease or gluten sensitivity.
