Can you stay healthy this way?
Pizza may be a tasty dish now and then but you will find that it would make a very unhealthy diet.
A medium pepperoni pizza has far too much sodium and potassium to be healthy, a medium, thin crust cheese pizza has enough low-density lipoprotein to suffice for a week, and if you load on sausage, pepperoni, and extra cheese you will have to work overtime at construction at least a week on lettuce leaves and oatmeal to clear the LDL from your arteries.
but i heard that pizza is good for health as it contains vegetables and cheese.
Yes, you can put anything on a pizza.. Even certain fruits and vegetables.. You don't have to live on meat alone.
