I think once Roberto caporuscio told me that he had an article from a famous US Newspaper that did a comparative analysis between Pizza Napoletana and US pizza and the results were that Pizza Napoletana was much lighter and better nutritionally balanced.
I believe this is an abreviated account of the information you are refering to Marco:
Madelyn Fernstrom of the UPMC Weight Management Center (University of Pittsburgh Medical Center ) c. 2004 came up with the following information:.
The weight management center has been analyzing the pizza made by Roberto Caporuscio.
Fernstrom's department has calculated that the 5-inch Regina Margherita pizza has 461 calories, 16 grams of protein and 9 grams of fat. That's close to 420 calories in just one slice of an extra large cheese Pizza Hut pizza (cut in 12 pieces), according to that restaurant's nutrition facts. That one slice has 15 grams of fat and 20 grams of protein.
A 12-inch medium cheese hand-tossed Pizza Hut version (at 240 calories a slice -- cut in eight slices for a medium) would have 1,920 calories. That compares with a 12-inch Regina pizza at 800 calories.
