Fun fact: Brazilian Italians came from northern Italy (venesians, lombardi's, etc) before the 1900s and American Italians came from southern Italy (campanha, calabria, scicily, etc) after the 1900s. Because of the latin culture and language, Italians fully integrated with brazilians but were fully segregated in the US. Today, they couldn't be more different to each other. So much so, that Brazilian Italians are not that big in pasta because they used to eat rice and polenta with just a sprinkle of pasta recipes (just the famous ones, like bolognese) before coming to Brazil.
