Gluten-free Diet

A gluten-free diet means not eating foods that contain wheat, rye, and barley. The foods and products made from these grains should also be avoided. In other words, a person with celiac disease should not eat most grain, pasta, cereal, and many processed foods.

Despite these restrictions, people with celiac disease can eat a well-balanced diet with a variety of foods. They can use potato, rice, soy, amaranth, quinoa, buckwheat, or bean flour instead of wheat flour. They can buy gluten-free bread, pasta, and other products from stores that carry organic foods, or order products from special food companies. Gluten-free products are increasingly available from mainstream stores.

“Plain” meat, fish, rice, fruits, and vegetables do not contain gluten, so people with celiac disease can freely eat these foods. In the past, people with celiac disease were advised not to eat oats. New evidence suggests that most people can safely eat small amounts of oats, as long as the oats are not contaminated with wheat gluten during processing. People with celiac disease should work closely with their health care team when deciding whether to include oats in their diet. Examples of other foods that are safe to eat and those that are not are provided in the table.

The gluten-free diet requires a completely new approach to eating. Newly diagnosed people and their families may find support groups helpful as they learn to adjust to a new way of life. People with celiac disease must be cautious about what they buy for lunch at school or work, what they purchase at the grocery store, what they eat at restaurants or parties, and what they grab for a snack. Eating out can be a challenge. When in doubt about a menu item, a person with celiac disease should ask the waiter or chef about ingredients and preparation or if a gluten-free menu is available.

Gluten is also used in some medications. People with celiac disease should ask a pharmacist if prescribed medications contain wheat. Because gluten is sometimes used as an additive in unexpected products—such as lipstick and play dough—reading product labels is important. If the ingredients are not listed on the label, the manufacturer should provide a list upon request. With practice, screening for gluten becomes second nature.
