Are you on a gluten-free diet and wondering why your symptoms aren't getting better? Jacalyn See, a registered clinical dietitian, discusses the risks of hidden gluten and provides tips to help patients with celiac disease maintain a gluten-free diet.
There are many places where hidden gluten can arise. It can occur in the home, restaurants, in other people's homes, fields or factories, and from unclear labeling on food products.
Hidden gluten may occur in your own kitchen, especially if some family members are maintaining a regular diet. Here are some examples of where hidden gluten may arise due to the accumulation of crumbs:
How can you reduce this problem? This is a personal choice. One way to reduce the risk of hidden gluten is to have a gluten-free kitchen or a gluten-free household. Another way is having a separate area for gluten-free items such as a separate toaster, condiment jars, or drawers.
Restaurants are another place where hidden gluten may occur. This happens through cross contamination between gluten and gluten-free items in deep fryers, grills, soups and dishes with multiple ingredients, and salad bars. Kitchens play a larger role in cross contamination through lack of proper food handling and poor employee education. Here are some tips to protect yourself from hidden gluten while eating in a restaurant:
Eating at someone's home can also be challenging when trying to maintain a gluten-free diet. To prepare, call the host or hostess and find out what is being served.
Contamination in the field or factory is another source of hidden gluten. This can occur in fields where gluten-free grains are adjacent to wheat fields. It can also occur in shipping, storage, and processing. To avoid this situation, avoid foods labeled "made in a facility with," "made with shared equipment," and buy grains labeled gluten-free.
The Food Allergy Labeling and Consumer Protection Act requires that wheat be labeled clearly on all items containing wheat. However, manufactures are not required to label malt or barley. Medications and vitamins can also be a source of hidden gluten. It's best to buy items labeled gluten-free, contact the manufacturer, or ask a pharmacist if you have questions.
