Updated:CHARLOTTE, N.C. —
Starting Tuesday, gluten-free labels on packaged foods will have real meaning.
Until now, the term gluten-free had not been regulated, and manufacturers made their own decisions about what it meant.
Now, anything labeled gluten-free will contain less than 20 parts per million of gluten -- ensuring those products are technically free of wheat, rye and barley.
This new requirement is especially important for people who suffer from celiac disease.
