Live longer with these dishes from 'blue zones' in America | CNN
"Blue zones" are places around the world where people often live to be 100 or even older. One key to this longevity is a plant-based diet. "Blue Zones" author Dan Buettner showcases such places in the US in his new cookbook.

One of the most visually striking recipes in the book is made from purple sweet potatoes, which Buettner considers a key longevity staple for people in the blue zone of Okinawa.
“The dietary intake of Okinawans until 1975 came from purple sweet potatoes,” he said. “I would argue it produced the longest-lived population in the history of humankind.”
Blue zone recipes were also found in Gullah Geechee cuisine, a method of cooking developed by descendants of enslaved Africans who settled in the Sea Islands of Georgia, Florida, North Carolina and South Carolina. Stews and soups may be thickened with benne seeds, an heirloom version of sesame seeds brought over on slave ships.
