Is pizza a lipid carbohydrate or protein?

Answer 1

The answer to that question is that all three of these substances are found in Pizza. Lipids are generally found in fatty substances and since pizza contains many of these it is loaded with lipids.
Complex carbohydrates are contained in the dough that the crust of the pizza is composed of and simple carbohydrates are in the vegetables.

Meat and cheeses will contain proteins and as you load meat onto your pizza you load it with more protein.
