Buettner who travels the globe to examine and unlock the secrets of long life has written a book called The Blue Zones: Lessons for Living Longer From the People Who’ve Lived the Longest. For the Sardinian people, this could be a diet of bread, wine and cheese. The cheese, known as pecorino sardo, is made from grass-fed sheep’s’ milk that results in a product which is high in omega-3 fatty acids. It was being made in Sardegna centuries before the Romans captured the island.
Sardinians also eat a diet of fiber rich fava beans (high in folate), a type of nutritive wafer thin bread known as Carta da musica and a leavened bread made with a bacteria used to rise the bread that creates a mixture of substances with positive effects (vitamins and lactic acid that may counter attack probable harmful bacteria found in the digestive tract). They wash this all down with divided amounts of Cannonau, a dark red wine said to contain the world’s highest levels of antioxidants.
Buettner is quick to acknowledge that nothing can be said for sure but his findings are based on the way the longest-lived people in the world eat and some of them happen to live in Italy.
