Without meaning to defend it too much, as I believe it's mostly a marketting/lobying thing...
As I understand it, the issue was whether or not you could count a pizza towards your vegetable quota. The argument came down to the nutritional content of the tomato sauce on the pizza; nutritionally, this was very similar to the requirements for other things that can be classified as vegetables, and so one portion of pizza was deemed to also count as one portion of vegetables.
