almost forgot. most sources say xylitol is the cat's pajamas for everything, tooth decay control, sugar replacement for glycemic control, i have even seen people recommending it for use as a supplement, i can't imagine why. then i heard someone say that it causes brain damage (in humans) it took me a while to track it down and i'm still looking for where i put it, but i found a study out of Duke university that said that it did cause brain damage. i only found the 1 study, so make of it what you will.
