Oats are naturally gluten free so there is no ''removing'' gluten process. To ensure purity, gluten-free oats, also known as purity protocol oats, are grown in separate fields and processed in facilities that have never handled gluten-containing grains. While oats themselves do not contain gluten, this strict process guarantees there is no cross-contamination from grains that do. However some gluten-free intolerant or people with celiac disease still cannot tolerate oats.
