Celiac disease patients with a better adherence to a gluten-free diet over the long term had a lower risk of developing symptoms of depression. About a third of patients developed symptoms of depression over their lifetime despite adherence to a gluten-free diet. (17)
Beer is often overlooked as a source of gluten.
Gluten free diet for gluten-related disorders:
Once diagnosed with a gluten-related disorder, treatment is focused on elimination of all sources of gluten from the diet. Even small amounts of residual gluten in the diet are known to contribute to the celiac disease process. Dietary counseling is based on support of the patient in the major lifestyle change of a gluten-free diet for life. This is best accomplished by a qualified dietitian. Adherence may be difficult due to the large variety of processed foods in the U.S. which contain gluten. Patients will require education to avoid all foods containing wheat, rye, barley (including all types of beer), and oats. Distilled alcohol beverages and wine are generally free of gluten. Patients should be counseled to avoid occult sources of gluten in foods. Gluten containing foods should be substituted for corn, soy, buckwheat, beans, vegetables, fruits, nuts, tapioca flour, rice, potatoes, and lean meats. Oat consumption is controversial, with research showing that oats may provoke gluten related disorder, while other research has supported oats as generally safe to consume.
