The GFCF Diet is an acronym for (Gluten Free Casein Free Food). A gluten-free casein-free diet (or GFCF diet) eliminates intake of the naturally-occurring proteins gluten (found naturally in wheat, barley, and rye) and casein (found in milk). Brown and white rice flours form the basis of most gluten free baking. Brown rice flour contains more nutrients because it is less refined. Sweet rice flour makes an excellent thickener for gravies or cream sauces. Sometimes called glutinous flour, it does not contain any gluten. Jowar flour is another name for sorghum flour.
