<<Disclaimer: Verify this information before applying it to your situation.>> Dear Listmates: I found a really good buy on Atkins shakes & carefully checked the ingredients list on the packaging & checked the information available on the Atkins website. I couldn't figure out what in my diet was causing symptoms & since I had started mixing the shake with soy milk, I contacted the soy milk manufacturer to find out if something had changed in their production. The reply was that nothing had changed, it was still gluten free. So I stopped drinking the shakes & felt better. Then I sent an e-mail to Atkins. Here's the answer - oops!! The Shakes are NOT gluten free. I apologize for not addressing that question in your previous email. I had also asked about the Atkins bars & here is the reply I got about them: Thank you for your inquiry in regards to Gluten in the Atkins Advantage Bars. You'll be pleased to know that almost all of the bars are Gluten free. Here is a listing of the flavors: Creamy Lemon Chiffon Creamy Berry Cheesecake Almond Brownie Banana Colada Chocolate Coconut Chocolate Macadamia Nut Chunky Peanut Butter Chocolate Peanut Butter Chocolate Rasberry I am now going to e-mail Atkins again and ask why the shake products contain gluten & why this information is not clearly identified at the Atkins website. I'll update for the list. Helen in Vancouver, BC
