There are many reasons people who wish to lead a healthier lifestyle chose to avoid gluten in their diets. Those with gluten allergies and intolerances, however, don't have a choice. For them, consuming undetected gluten poses a real health risk. The trouble is that traces of gluten can be found in foods that don't naturally contain it, due to cross-contamination, cooking methods, food additives, etc. This is especially true when it comes to restaurant and commercially processed food.
