Simple question:

Are those low carb bars listed in the induction list of safe foods? If it isn't in there, then no they are not okay. (hint....they arent)

Currently the US government has some major issues with the so called health food manufactors because of the way they label their foods. It has to do with sugar alcohols and the way the body processes them. Some people are affected others arent. Your mileage will vary.

Do a search on Low carb bars on this web site and you will find tons of threads covering the bad parts.
