I was on Taste of the Wild website and found this article on xylitol (Wikpedia def - Xylitol is a five-carbon sugar alcohol that is used as a sugar substitute). I understand it is in gum and other foods that is supposed to be good for your teeth. If this was posted I apologise but didn't see anything in a search.
