'Gluten-Free' Food Labels Now Mean What They Say

Any food with a "gluten-free" label in the United States now must meet a new set of standards outlined by the Food and Drug Administration (FDA).

The new rule goes into effect today (Aug. 5), and requires that foods labeled gluten-free have less than 20 parts of gluten per million parts of food — the lowest level that can be detected with current measuring tools. Any food labeled gluten-free cannot contain wheat, rye, barley or any of their crossbreeds, unless the grains are first stripped of gluten.
