Cultural Tip
In Italy the Mediterranean diet emphasizes legumes (lenticchie, ceci, fagioli), fish, and dairy as primary protein sources. While meat is common, many Italians prefer lean cuts and incorporate plant‑based proteins. Remember that in informal speech you can drop the article and say 'Quali sono buone fonti di proteine?' but in formal writing the article 'le' before 'fonti' is preferred.
