You might want to visit health-food stores more often, since these carry many gluten-free foods. In a regular grocery store, safe foods for people who can't digest gluten tend to be located along the perimeter: fresh fruits and vegetables, unprocessed meats, fresh seafood, milk, eggs, yogurt, butter and unprocessed cheese. Other safe foods include clear soups, packaged fruits and vegetables, plain nuts, unflavored potato chips, popcorn and sugar. All grains aren't forbidden, by the way. You can enjoy those that are naturally gluten-free, such as corn, quinoa, rice, soy and potato flour. When dining out, be prepared to talk to the wait staff or someone from the kitchen about which ingredients are OK and where substitutions are needed. But take heart: An increasing number of restaurants cater solely to people with celiac disease.
