Is Pizza Junk Food?

Assuming your toppings consist of meat and veggies as well

I think it's considered whatever the pizza consists of, there is alot of oil and fats depending on where it's made.

Home-made ones with the right ingredients are fine. Just so long as you don't make the mistake of buying anything from a supermarket. If you make it from scratch with ingredients from a specialist store without all the sugar and crap like that in it, it's fine to eat all day long.

well it really depends bc you can make a pizza from fats and meats , to a vegetarian pizza

Pizzas from restaurants or from supermarkets contain your quota of fat and salt for the entire week. That should tell you a lot.

not if it is topped with shrooms.

Then it's considered parapharnalia.
