I’m not going to say you’re wrong about aspartame being safe because I don’t know for sufe, but I question whether you’re right. The fact that Donald Rumsfeld was the CEO of the company that held the patent, couldn’t get it approved then magically got it approved after his buddy Ronald Reagan appointed him to a position where he could do so makes me wonder if it ever should have been approved.
