Is it? I doubt there are many fibers in there. Unless you count the tomato sauce it doesn’t really contain a lot of vegetables either. I’d be really surprised if tomato sauce on the average pizza is healthy, it’s probably so over processed that all the fibers and vitamins etc are gone and it’s just a big carb nuke. And a pizza contains too much fat as well. A good pizza might be decent compared to most fast food, but I can’t imagine the average fastfood or supermarket pizza being a healthy meal.
