This Delicious Herb Might Be Why The Italians Live So Long

In Acciaroli, Italy, a remote village of only a few thousand people -- if that many -- there's a staggering number of centenarians -- 300 -- and experts don't think it's a coincidence. That's why researchers from the University of California, San Diego and the University of Rome, La Sapienza are teaming up to study them. 

The coastal city is located south of Naples, next to the Tyrrhenian Sea, where locals often get around on foot and enjoy a Mediterranean Diet that relies heavily on the herb rosemary. Rosemary is thought to improve memory, and to help with blood circulation and the nervous system. The Mediterranean Diet as a whole is rich in fruits, grains, vegetables, and seafood.
