Washington — Starting Tuesday, “gluten free” labels on packaged foods had real meaning. Until then, the term “gluten-free” was unregulated, and manufacturers made their own decisions about what it means.
This new requirement is especially important for people who suffer from celiac disease and don’t absorb nutrients well. They can get sick from the gluten found in wheat and other cereal grains.
Under a rule announced a year ago, food manufacturers had until this week to ensure that anything labeled gluten-free contains less than 20 parts per million of gluten — ensuring that those products are technically free of wheat, rye and barley. That amount is generally recognized by the medical community to be low enough so that most people who have celiac disease won’t get sick if they eat it.
Currently, wheat must be labeled on food packages but barley and rye are often hidden ingredients.
Celiac disease causes abdominal pain, bloating and diarrhea, and people who have it can suffer weight loss, fatigue, rashes and other long-term medical problems. Celiac is a diagnosed illness that is more severe than gluten sensitivity, which some people self-diagnose. According to the American Celiac Disease Alliance, an estimated 3 million Americans have celiac disease.
A decade ago, most people had never heard of celiac. But awareness and diagnosis of the illness have grown exponentially in recent years. It’s not entirely clear why. Some researchers say it was underdiagnosed; others say it’s because people eat more processed wheat products, such as pasta and baked goods, than in past decades, and those items use types of wheat that have a higher gluten content.
The standard will ensure that companies can’t label products “gluten-free” if they are cross-contaminated from other products made in the same manufacturing facility. The rules don’t apply to restaurants, but the Food and Drug Administration is encouraging them to comply.
Gluten-free foods have become big business in the last several years, topping an estimated $4 billion in sales last year.
