Does pizza protect against cancer?

Italian researchers dug into a big network of hospital studies run between 1991 and 2000, comparing thousands of people with various cancers against people in hospital for other reasons, and asked one crucial question: how much pizza do you eat?

Regular pizza eaters had lower odds of several cancers of the mouth, throat and digestive tract. The authors call pizza a “favorable indicator” — likely a sign of a healthy Mediterranean diet — not a miracle cure. Italian nonnas everywhere remain unsurprised.
