Blue Zones Diet: Dietary Secrets from the World's Longest-Living Communities

The concept of "Blue Zones" was introduced to the world through the investigative journalism of Dan Buettner, who collaborated with National Geographic and a team of longevity researchers to uncover the lifestyle secrets of communities with unusually high numbers of centenarians – those who live past 100 years of age. These pockets of extraordinary longevity are found in specific regions worldwide, namely Sardinia, Italy; Okinawa, Japan; Nicoya Peninsula, Costa Rica; Ikaria, Greece; and Loma Linda, California.
