A gluten-free diet helps manage symptoms of celiac disease and other medical conditions associated with gluten consumption. It means eating only whole foods that don't contain gluten, such as fruits, vegetables, meat and eggs, as well as processed gluten-free foods like gluten-free bread or pasta.

The claimed benefits of the diet are improved health, weight loss and increased energy. As one of the criteria for using the claim "gluten-free," FDA set a limit of less than 20 ppm (parts per million) for the unavoidable presence of gluten in foods that carry this label.
