The BBC just publish an article in their "World's Table" section called "Is there no such thing as Italian cuisine?" which is about the new book La Cucina Italiana Non Esiste. The author is Alberto Grandi, food historian and professor of economic history at the University of Parma.

One example given in the article about pizza:
Pizza is the most famous example of this. Born as a cheap street food
in Naples, in the 19th Century it was almost synonymous with poverty
and filth. Pizza is "a crust of leavened bread dough, oven-toasted,
with a sauce of a bit of everything on top", wrote Pinocchio author
Carlo Collodi in 1886. He added that pizza had "an air of complex
filth that perfectly matches that of its vendor".
Grandi has a podcast Denominazione di Origine Inventata (DOI) which is co-hosted by Daniele Soffiati. It is in it's fourth season and is quite interesting. Grandi doesn't take issue with the quality of the food, just the stories that are invented around it. One thing he often mentions his how many people immigrated from Italy between 1850 and 1914 (like my great grandparents), hunger being one of the main reasons.
