<<Disclaimer: Verify this information before applying it to your situation.>> Wendy, I have used Cocoa Pebbles (one package) for variety, had no obvious problem but I will not repeat them but I will try Fruity Pebbles and see what they taste like. Post claims them both to be GF. My favorite is Sun Flakes and in cool weather I like Grits or Cream of Rice with syrup. I use Corn Pops as an occasional change of taste and texture. Bob in FL
