I heard a lobbyist for the tomato paste industry talk about this on the radio the other day. He said it is full of vitamins and nutrients. But I think this is one of those times when we need to stop listening to talking heads and just use common sense. Pizza is not healthy food.
It is not the worst food out there, and there are several types of pizzas where some are a lot healtiher than others.
When I eat pizza I usually eat the Italian types witch is usually small/medium in size and have a thin crust. These
pizzas dont have much calories at all in them, and some of them even consists of chicken on top, so its not bad at all.
