How many calories in a DiGiorno cheese pizza? A whopping 1,740 calories if you eat the entire thing. Assuming you slice it into 6 pieces, it's 290 calories per slice. As the case with most frozen foods, the sodium is high - 670 mg per slice or 4,020 mg for the entire thing. Considering that (and the cholesterol, saturated fat, etc.) it's hard to make the case that DiGiorno pizzas are healthy, especially when you consider the ORAC value is so low. Keep in mind, too, that it was measured using a frozen pizza. Cooking it may actually lower the amount of antioxidants, since heat destroys many nutrients such as vitamin C (which yes, it does contain a little).
