<<Disclaimer: Verify this information before applying it to your situation.>> I called Balance Bar about a year ago concerning the gf status of their bars. I was told that they could not gaurantee Balance Bars were gf. I recently read the summary dealing with power bars. In this summary listmembers said Balance Bars were gf. I decided to email the comapany and I got this response from Craig Jennings at Balance Bar: "The only bar that contains gluten is Almond Butter Crunch." He did not say anything about the belts being floured. From the emails I read recently it seems soy lecithin is used on the belts. Hope this helps. Doug Indiana, USA
