Does whole grain rolled oats contain gluten?

While oats themselves are naturally gluten-free, they are often processed in facilities that also handle wheat, barley, and rye, which contain gluten. This can lead to cross-contamination, meaning that the oats may become contaminated with gluten during processing.

To be considered safe for people with celiac disease or gluten sensitivity, oats must be certified gluten-free. Look for labels that specifically state "gluten-free" or "certified gluten-free."
