The folks at DiGiorno -- those of the "it's not delivery, it's DiGiorno" commercials -- have launched individual-sized frozen pizzas.
They appear to have no problem with someone consuming:
11 grams of saturated fat (55% of a day's worth)
1,170 milligrams of sodium (half a day's worth)
... in one sitting.
Not surprisingly, fiber shows up at a paltry 3 grams (that's basically one gram per 200 calories!)
Those values are equivalent to what you get from three slices of Domino's pepperoni pizza.
I am not a huge fan of frozen pizzas (I like to buy ready-to-bake Rustic Crust whole grain crust and make my own), if single-person ones are on your grocery list, I recommend:
Earth's Best (380 calories, 6 grams saturated fat, 760 milligrams sodium, 8 grams fiber)
Lean Cuisine (320 calories, 2.5 grams saturated fat, 540 milligrams sodium, 4 grams fiber).
