Is pizza a protein or dairy?

Pizza is neither strictly a protein nor a dairy. It's a combination of different food groups:

* Protein: The pizza dough contains gluten, which is a protein. The toppings, like pepperoni or sausage, are also high in protein.

* Dairy: The cheese is the primary source of dairy in pizza.

* Carbohydrates: The pizza dough is primarily made from carbohydrates.

* Fats: The cheese, toppings, and even the dough itself contain fats.

So, while pizza has components from both protein and dairy categories, it's more accurate to call it a mixed food.
