Quaker does not label any of its products as gluten free because of the possibility of cross-contamination with other grain types or foods in the manufacturing or shipping process. Products such as Quaker Oats do not contain gluten naturally.
Gluten is a protein combination found in wheat, rye and barley, which gives elasticity or stretchiness to dough. Labels should be checked carefully for information concerning the possibility of gluten contamination. Certified gluten-free oats are available for purchase from brands such as Bob's Red Mill.
Oats are generally considered a safe food for celiac patients as long as the oats are processed separately.
