Far from being just a glib reminder to take it easy on junk food, “you are what you eat” is literally true on a chemical level. When you break down food into its molecular components, the isotopes of the elements contained within get incorporated into your body. Featured VideoNow a new study applies that method to a 2,700-year-old Italian necropolis, and it’s revealing more than just the inhabitants’ diet. Discovered in the late 19th century, the Novilara necropolis is located near Italy’s northeastern coast and contains hundreds of bodies. Curiously, despite being a stone’s throw from the Adriatic Sea, those buried in Novilara didn’t eat a lot of seafood.
