Gluten-free labels

Although gluten intolerance is different from a food allergy, it can cause serious symptoms. Gluten causes serious health problems in people who have celiac disease, a chronic digestive disorder. Gluten is a protein that occurs in grains such as wheat, barley and rye. It's found in many foods and food ingredients.

The FDA has established initial guidelines for use of the term "gluten-free" on food labels. Currently, the "gluten-free" label is voluntary — it's up to the manufacturer whether to include it. Many foods are naturally gluten-free and may or may not be labeled as such. The FDA is in the process of refining guidelines for gluten-free labeling.

The bottom line: Be cautious

Always double-check labels to be sure you know what you're eating and drinking. Even though a food product may have been safe the last time you purchased or consumed it, it's possible that the ingredients have changed or the label has been updated. If you have any doubt about food ingredients, contact the manufacturer about whether the food possibly contains a food allergen.
