Is gluten free the same as grain free?

No, gluten-free is not the same as grain-free. Gluten is a type of protein found in certain grains such as wheat, barley, and rye. A gluten-free diet eliminates these specific grains. However, a grain-free diet goes a step further by eliminating all grains, including rice, oats, and corn, which are typically considered safe on a gluten-free diet. Thus, while all grain-free diets are inherently gluten-free, not all gluten-free diets are grain-free.
