I almost posted this question 5 minutes ago! How eerie. I had the same thought today.
(I mentioned this to a relative who dryly said, "if you're a believer, it's flesh, not bread, and is therefore induction legal." I can't believe he said that with a straight face, but was obviously kidding).
Anyway, I'm curious to hear thoughts on this, too. Here's my two cents. While it's clearly not induction "legal," the amounts of anything in there certainly cannot be enough to cause any ill effects on ketosis, etc. I'd call it "trivial" and would probably breathe more carbs in standing in a bakery.
Our church skipped handshaking and drinking from the cup from the swine flu, which is now in my state. I don't drink from the cup anyway - that skeeves me out.
