People might follow a gluten-free diet for any number of reasons from an intolerance to grain or a lifestyle change. In short, a diet that is gluten-free means that one cannot eat any kind of bread, wheat or grain product. This can be a difficult thing to do, but more grocery stores are starting to carry whole aisles dedicated to the diet. A journal can help gluten free dieters set realistic goals if they are diving into this diet head first. However, it can also help those with an intolerance deal with their feelings when all they want is fried chicken.
