A gluten-free diet (GF diet) is a diet that excludes foods containing gluten. Gluten is a protein complex found in wheat (including kamut and spelt), barley, rye and triticale. A gluten-free diet is the only medically accepted treatment for celiac disease. Being gluten intolerant can often mean a person may also be wheat intolerant as well as suffer from the related inflammatory skin condition dermatitis herpetiformis, There are a smaller minority of people who suffer from wheat intolerance alone and are tolerant to gluten.
“Despite the health claims for gluten-free eating, there is no published experimental evidence to support such claims for the general population.” A significant demand has developed for gluten-free food in the United States whether it is needed or not.
