In a recent review published in Nutrients, researchers use environmental, nutritional, and lifestyle data to determine whether Cilento, Italy, shares trait characteristics with ‘Longevity Blue Zones (LBZs).

LBZs, which are often referred to as ‘blue zones,’ are regions throughout the world with distinct geographical profiles but shared long citizen life expectancy. These regions include Okinawa Prefecture, Japan, Nuoro Province, Sardinia, Italy, the Nicoya Peninsula, Costa Rica, and Icaria, Greece. However, many scientists hypothesize that this list is not exhaustive, with other LBZs potentially waiting to be discovered.
