Which food item is recognized as gluten-free?

Oats are recognized as gluten-free, but this acknowledgment comes with a caveat. Raw oats themselves do not contain gluten, which is a protein found in wheat, barley, and rye. However, oats are often processed in facilities that handle gluten-containing grains, leading to possible cross-contamination. Therefore, it's crucial for individuals with gluten sensitivities or celiac disease to choose oats that are specifically labeled as gluten-free, confirming they were processed in a dedicated environment free from gluten contamination. This attribute makes oats a suitable grain option in a gluten-free diet when sourced appropriately.

In contrast, barley, rye, and wheat are not gluten-free as they all contain gluten, making them unsuitable for those who need to avoid it.
