I didn't know that, thanks for the info. It's just sickening. Another reason why I won't use fluoride toothpaste. How does the FDA justify allowing this stuff in products? I heard that aspartame got invented by accident by a scientist trying to make some kind of ulcer drug. I don't know if it's the truth or not, but I heard the pentagon actually had it listed as a chemical warfare agent early on. I know they say everything will kill you these days, but some of these chemical additives will probably get the job done quicker.
