<<Disclaimer: Verify this information before applying it to your situation.>> Argh! I totally have felt like barfing since Saturday evening after eating a sandwich made with two slices of GF rice bread. This makes the second time I've gotten really sick for several days since going GF. Both times was after eating baked goods leavened with yeast. I have, however eaten baked goods containing xanthan gum & leavened with baking powder with no problem at all. I know for sure now, I'm yeast sensitive. This is really a big disappointment to me because that Kinick-Kinick bread was REALLY delicious. Does anyone know how to make a decent GF sandwich bread without yeast? ~Valerie in Tacoma, WA
