The Blue Zone: A Book Review

By Sally J. Feltner, M.S., Ph.D.

Ponce de Leon began his quest for the fountain of youth in 1531 and humans have been seeking magical solutions for keeping us younger and living our later years in relatively good health.

In 2009 with the backing of the University of Minnesota School of Public Health, AARP and the National Geographic, Dan Buettner established the Blue Zone Project and authored The Blue Zones: 9 Lessons for Living Longer from the people who lived the longest, He interviewed those who were either centenarians or those in their later years and began to investigate what factors may have contributed to five regions of longevity hot spots in the world that included:

• Sardinia in Italy with the highest concentration of centenarian men.
• Seventh Day Adventists in Loma Linda, California, where some residents live ten more healthy years than the average American.
• The Nicoya Peninsula in Costa Rica that has the world’s lowest rates of middle-age mortality and the second highest concentration of male centenarians.
• Ikaria, Greece that has one of the world’s lowest rates of middle age mortality and lowest rates of dementia. Only 20 percent of people over 80 showed any signs of dementia, whereas a similar study of long-lived people near Athens showed an almost 50 percent rate of dementia- a rate similar to that for older Americans.”
• Okinawa, Japan home to the world’s longest living women.

Remarkably, all the regions had common characteristics that included family and purpose, community and spirituality, stress reduction and physical activity. Mr. Buettner later published The Blue Zones Solution and coauthored with Ed Diener, The Blue Zones of Happiness.

One major practice was that all their diets, though not vegan, were predominantly based on plants. Meat and other animal products are either the exception or used as a condiment. Okinawans, practice a philosophy called hara-hachi bu regarding food; they only eat until they are 80% full

In the Costa Rican Zone, everyone feels like they have a plan de vida or life plan. Even at ages above 60 and 70, inhabitants don’t stop living. They keep themselves busy; they love to work. It provides them a “reason to waking up in the morning” called ikigai. There is no word for “retirement” in Okinawa.

The book introduces some very interesting longevity “superstars.”

• Marge Jones, at 100 years old from Loma Linda begins every day with a mile walk, a stationary bicycle ride, and some weight lifting. “I’m for anything that has to do with health”, she says
• Kamada Nakazitam, 102 years old from Okinawa says “To be healthy enough to embrace my great – great grandchild is bliss.”
• Ellsworh Wareham, age 91 from Loma Linda, assists during heart surgery procedures, something he does about two or three times a week
• Abuela Panchita, 100 year old Costa Rican woman whose 80 year old son, Tommy bicycles to see her every day, spends every day cooking, splitting logs and using a machine to clear brush from her
• The notion of moai in Okinawa stands for “a social support network. Says 77 year old Klazuko Mann, “each member knows that her friends count on her as much as she counts on her friends.”
• From the author: “I once pressed a 101-year-old woman in Ikaria, Greece to tell why she thought people there lived so long. ‘We just forget to die,’ she said with a shrug. None of them went on a diet, joined a gym, or took supplements. They didn’t pursue longevity – it simply ensued”

The final chapters in the first book boil it all down into nine lessons and a cultural distillation of the worlds’ best practices in longevity. Buettner provides credible information available for “adding years to your life and life to your years.”

However, there is a downside that is currently happening. From the Author: “Sardinians today have already taken on the trappings of modern life. For example, junk foods are replacing whole-grain breads and fresh vegetables traditionally consumed here. Young people are fatter, less inclined to follow tradition, and more outwardly focused.”

The first book concludes with a chapter on Your Personal Blue Zone. Other books give us more explicit ways to establish Blue Zones in other areas such as the U.S.

From the back cover of The Blue Zones Solution – “Propagating the Blue Zones would not only prevent a rise in the prevalence of diabetes (and other misfortunes) it would allow us to eliminate more than 80 percent of the burden we have now. That’s revolutionary.”
