In the southernmost region of Japan lies Okinawa, a cluster of islands famous not only for its turquoise waters and vibrant culture but also for something truly extraordinary: longevity. Okinawans are among the longest-living people in the world, with a remarkable number of centenarians (those over 100 years old).
Their secret? A unique way of eating and living, known as the Okinawa diet.
Let’s explore what the Okinawa diet is, why it’s linked to longevity, and how you can bring its principles into your own lifestyle.
