<<Disclaimer: Verify this information before applying it to your situation.>> I stepped over the line a couple of weeks ago to solve the maltodextrin question for myself. I tried a bag of Tim's Cascade potato chips in which maltodex was the only iffy ingredient. I'm sorry to say that, for me, it was bad news. My reactions are usually limited to sense of well being. I've become pretty good at telling when I've ingested gluten. I hope this little bit of empirical evidence can help. John P.S. Did I already write this?
