(HealthDay News) -- Celiac disease is an overactive immune system disorder affecting about 1 in 100 people worldwide, says the Celiac Disease Foundation.
People with celiac disease may well damage their intestines by eating foods that contain gluten. Currently, the only treatment is a strict gluten-free diet.
Foods with wheat, rye or barley -- such as breads and beer -- must be avoided. Naturally gluten-free foods include fruits, vegetables, meat, poultry, seafood, dairy, beans, legumes and nuts.
For people with celiac disease, it is extremely important to always read nutrition labels. Some processed foods, such as dried fruit, can contain gluten.
