Just stay away from the dream fields stuff and 99 percent of the chocs! I buy the ketchup and the davinci syrups for flavoring, because neither have polyols in, and that's all.
I did try some walden farms stuff but it was all vile - and I've tried some of the baked things on previous goes at Atkins but they've stalled me and it's so much cheaper/easier to make my own.
