Meh, if I was keeping my diet kosher/was fasting, I would not eat it. It defeats the whole purpose of kosher/keeping a fast. The purpose is sacrifice, or at least for the fasting part. One is akin to a lawyer looking for those legal loopholes by searching for all these replacements. Faith is not about this. If there is a God, he would not like this. Then again, I am an atheist, but that is beside the point.
