According to recent diet trends paralleling the diets of humans as they evolved (Paleo, Primal, etc.), the worst part of the pizza is the wheat crust, followed by the cheese and possibly oils depending on how the pizza was made. "Primal" pizza substitutes are made with almond flour crusts, minimal dairy, and loads of fresh meat and veggies with oils such as olive oil.
