Ugh. I love my Coke Zero. So much for the government keeping us safe. How long have they been telling us this trash is ok??
This is rubbish.
They way they determined Saccharine caused cancer in rats, for instance, was to feed them the equivalent of drinking 100's of cans of Tab a day. The rats got sick from it. Imagine that.
Some people just can't accept the fact that LIVING is bad for you. And, others can't accept the fact that somewhere, someone might doing something that they enjoy so they work hard to stop it. (Lots of these control freaks are called "liberals", but I'm editorializing.... :-) )
IMHO, Moderation is the key. Nothing wrong with a Diet Coke or two. If you're going through a case or two a day, though, maybe you've got something to worry about.
