Tip - Is Polenta Gluten-Free? | eHow

Polenta, another name for cooked cornmeal or corn porridge, is naturally gluten-free. The only grains that do naturally contain gluten are wheat, rye and barley. Since so many other grains are processed in facilities that also handle wheat, rye and barley, however, some varieties of polenta may become contaminated with trace amounts of gluten.
