<<Disclaimer: Verify this information before applying it to your situation.>> In looking for snacks for my son that won't give him cramps, I came across all of the different brands of popcorn cakes (he hates rice cakes and I can't say that I blame him).The flavor of choice is, no surprise, the caramel corn flavor. Well, according to Quaker Oats, they still don't publish a list because of the possibility of cross-contamination. The corn cakes, however, are all GF *except* the bananna nut flavor (no big loss - I tried some and they weren't all that good). We've been trying out the Quaker Caramel Corn cakes and they are definitely a big hit with no signs of reaction (yet). I'm checking on the popcorn cakes from Orville Reddenbacher but, since they don't publish a number on their packages, it's taking a little longer. Just thought you'd all like to know what we found out! Enjoy! KJB
