“Blue Zone” is a nonscientific term given to geographic regions that are home to some of the world’s oldest and healthiest people. The individuals who live in these areas report low rates of chronic disease and long life expectancy.
The term was coined by Dan Buettner, an American author and explorer who studied areas of the world in which people live exceptionally long lives. In the course of conducting his research, Buettner termed these areas “Blue Zones” because he and his colleagues drew blue circles around them on a map.
In his book, “The Blue Zones,” Buettner details five known Blue Zones:
▪ Okinawa, Japan
▪ Sardinia, Italy
▪ Nicoya Peninsula, Costa Rica
▪ Icaria, Greece
▪ Loma Linda, California, USA
Blue Zone characteristics include:
▪ High life expectancy (many residents live to be over 100 years old)
▪ Low rates of chronic diseases such as heart disease, stroke, and cancer
▪ Strong social connections and community support
▪ Plant-based, nutrient-rich diets
▪ Active lifestyles with moderate exercise
Buettner details that genetics probably only account for 20% to 30% of longevity. Environmental influences, including diet and lifestyle, will likely play a huge role in determining your life span.
Buettner found that people who live in Blue Zones eat a diet full of whole plant foods. They tend to follow the 80% rule, which means that they stop eating when they feel 80% full, rather than 100% full. They consume alcohol in moderation, exercise in moderation, and get plenty of sleep.
Living longer, healthier lives is something we all can get behind. Incorporating “Blue Zone” practices into our daily routines may help us do just that!
