Are artificial flavors and colors gluten free?

Q: I know that natural flavoring may contain gluten, but what about artificial flavoring and coloring. Are they gluten-free?


Artificial flavorings and artificial colorings contain chemical compounds and are considered gluten free. However, note that some people may react to artificial flavors and/or colors for different reasons such as sensitivities and/or allergies.

As a general guideline, I always recommend that you only consume foods that are labeled gluten free (unless they are plain natural unprocessed GF whole foods). Foods that are labeled gluten free have to adhere to the FDA limit of 20 parts per million of gluten, which is considered a safe concentration for those with celiac disease.
