<<Disclaimer: Verify this information before applying it to your situation.>> Thank you kindly to all who responded. 3 sensitive celiacs had no problem with Bob's Red Mill Polenta/Corn Meal. Others recommended: Indian Head Brand Arrowhead Mills Cornmeal (which I have in my cupboard and states its GF status on the package, but is a finer grind--better for polenta than grits).
