So, since 20% more than 0 is still 0, the new ketchup still has no vitamin C. I find it hard to believe that they would try to get away with such a misleading claim. Are you sure you’re reading it correctly?
According to this site, vitamin C in ketchup is in fact a new thing – which suggests that it does have more than 0% now.
Here’s a site that sells lots of different types of ketchup, in case this hijack has picqued your interest. 
With regard to “Real” as a trademark: the USP&T Office lists 5,689 uses of the word in trademarks. None seem to match the claim that Stinky made (although my search was not exhaustive).
As for the opening post…
Are you really surprised that there are pizzas out there that have non-cheese cheese on them? You should check out the alleged cheeses at your local supermarket; if you read the label (and of course, you should always read the label), you will find a lot of “pasteurized proccess cheese food product” masquerading as real cheese. Yes, it’s so disgusting they actually have to tell you that it’s ‘food’. Most of the cheeses in the deli sections are OK (the expensive, small producer stuff), but anything with a major company label on it, like Kraft, or anything “individually wrapped” is just plain plastic. I gag everytime I see someone buy that shit.
And that’s how you mortally offend a cheese lover. Here endeth the rant.
Just what is the dividing line between low grade mozzerella and high grade edible white glue?
Wouldn’t that mean that the pizza contains nothing but cheese?
