Why is Frozen Pizza ultra-processed on average?
Frozen pizza must survive freezing, months of storage, and oven reheating while maintaining appetizing appearance and texture. The crust requires freeze-thaw stable dough conditioners (DATEM, sodium stearoyl lactylate). The sauce uses modified food starch to prevent water separation. "Mozzarella" on cheap pizzas is often a blend with modified food starch. Meat toppings (pepperoni, sausage) add their own layer of processing with nitrites and preservatives.

Is DiGiorno pizza ultra-processed?
DiGiorno pizzas carry long ingredient lists across crust, sauce, cheese and toppings; check the box for dough conditioners, modified food starch and phosphates. Each product page shows its own score.
