Q: I’ve been hearing about the world’s so-called “Blue Zones” what can you tell me about them?
A: There are specific regions world-wide where people live much longer and remain in far better health than the populations of all other regions of the world. Scientists have labeled these regions “Blue Zones”. Although there are close to twenty regions of the world that have been labeled as Blue Zones, the Blue Zones that have been extensively studied are the Italian island of Sardinia, the Japanese island of Okinawa, Costa Rica’s isolated Nicoya Penisula, the equally isolated Greek island, Ikaria, and Loma Linda, California. In all these regions, despite variations in diet and lifestyle related to cultural differences, there are strikingly similar dietary and lifestyle qualities that all of them share. Next week, in part two of my discussion about Blue Zones, I’ll go into detail about what these regions have in common that produces such health and longevity.
