A new book out (discussed on THE SPLENDID TABLE/NPR) called THE BLUE ZONES highlights where people regularly live over 100 yrs of age. They are small areas of Italy, Costa Rica, Okinawa and Loma Linda, CA. All these people have a similar PLANT-BASED diet, eating meat/fish sparingly. They also have a few close friends who they regularly interact with. The place in Italy drinks a wine that has 5 times the anti-oxidants of other wine. The people in Loma Linda are exclusively 7th Day Adventist and eat nuts and vegetable based diet (read "biblical-based) It was really an informative piece.
