Live Longer and Better: The Blue Zones

Do you know that a century ago, the human life expectancy in the United States was about 53 years? With the advancements in healthcare and increasing consciousness of our diet, the average life expectancy has extended to 78 years. In fact, there exists a couple regions in the world where 100 years old is commonly reached. These regions are given the name of “blue zones.”



There are actually 5 known regions that are now identified as Blue Zones!

  • Sardinia, Italy

  • The islands of Okinawa, Japan

  • Loma Linda, California

  • Nicoya Peninsula, Costa Rica

  • Icaria, Greece


So what is making them live so long? Well, besides the geographics and other natural advantages, the common characteristic of these populations is that they generally maintain a healthy diet and lifestyle; no smoking, less stress, plant-based diet, and moderate physical activity.



Obviously, we cannot just copy and paste all of their practices into our own lives, but we certainly can learn something from their lifestyles and maybe try to implement some of their staple foods into our diet!


In the next a few blog posts, we will be seeing the diet of each of the five regions more closely!
