Question 130 of 433

What are the Blue Zones?

Crates of grains, legumes and sweet potatoes at a market

The short answer

Five regions identified by the writer Dan Buettner and his research colleagues as having unusually many people who live past 90 and 100: Okinawa in Japan, Sardinia in Italy, Nicoya in Costa Rica, Ikaria in Greece, and the Seventh-day Adventist community of Loma Linda, California.

The name came from the blue ink researchers used to circle villages on a map. The idea became a set of books, a cookbook, and a documentary series, and it has influenced how cities are designed.
