Dan Buettner coined the term blue zones—regions around the world where people live the healthiest and the longest. These Centenarians share similar lifestyles, although living thousands of miles from each other.

Average life expectancy around the world is 77 years. However, award winning journalist and New York Times bestselling author Dan Buettner discovered five regions where people typically live to be over 90. Buettner named these cities ‘Blue Zones’ to identify them by their life expectancy. Researchers found that although their lifestyles change slightly, the people of blue zone areas were living longer and had more fulfilled lives compared to the rest of the world. This is due to their primarily plant-based diet, their spirituality, family and social networks, along with regular exercise and drinking moderate amounts of alcohol. The five cities classified as blue zones are Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Ikaria, Greece; Loma Linda, California. 

1. Okinawa, Japan

Okinawans are among the healthiest living people in the world and Okinawan women live the longest in all the earth, with an average lifespan of 90 years. They follow a plant based diet, eating mostly sweet potatoes, rice, grains and soy. The Okinawan household does not have much furniture; meals are eaten on tatami mats on the floor. By getting up and down several times a day to relax or eat their meals, older people are able to gain lower body strength and, in turn, protect themselves from having dangerous falls. In addition, their diet and active lifestyle of gardening and walking everywhere helps their body stay strong. Their physical and mental welfare is accompanied by a social network called Moai. This social network consists of lifelong friends who support each other emotionally and financially in times of need. Okinawans know that there are always friends who surround them and are willing to lend support in time of need. By these simple lifestyle habits, the people of Okinawa have been able to live centenarian lives with less illness than those in other regions. 

3. Sardinia, Italy

The Sardinian lifestyle has been culturally isolated from the rest of Italy as it is an island town. Sardinians' long life is the benefit of living within strong healthy families and a plant based diet accented with meat. Sardinian seniors are often surrounded by children and grandchildren, which results in lower rates of stress, depression and suicide. Men in this blue zone region are known for gathering in the street in the afternoons to share laughs with one another. Laughter reduces stress, which can lower one’s risk of cardiovascular disease. In addition to being surrounded with family and laughter, Sardinians still hunt, fish and harvest everything they eat. Their diet consists mainly of whole grain bread, fruits, beans and garden vegetables. An average of two glasses of wine daily are consumed by Sardinian residents, which is known to reduce stress among men. Meat is reserved for Sunday family meals and other special occasions. Although diet and family network help add years to Sardinians’ lives, a research team discovered that there is a rare genetic quirk carried by the island’s inhabitants.The M26 marker is linked to exceptional longevity, and due to geographic isolation, the genes of the residents in this area of Sardinia have remained mostly undiluted, resulting in nearly 10 times more centenarians per capita than the United States.

4. Nicoya, Costa Rica

The Central American nation of Costa Rica is home to Nicoya, an 80- mile peninsula just south of the Nicaraguan border. The people of Nicoya believe in having a sense of purpose for everyday living. This purpose encourages them to feel needed and want to contribute to a greater good. With the purpose driven life they live, they continue to work and find joy in their physical chores. Usually, they are surrounded with family and frequent social gatherings from friends and neighbors. Nicoya centenarians regularly take in the sun. This helps their bodies produce Vitamin D which is known to keep bones strong and contributes to a healthy body function. Their Mesoamerican diet consists of corn, squash and beans. These foods are rich in vitamins, proteins, fiber and healthy fats,creating a complete, nutritional diet that has helped Nicoya people live well into their 100s. 

4. Ikaria, Greece

The small island of Ikaria in Greece sits on the Aegean Sea and is home to an almost dementia-free society. Lifestyle, clean air, relaxed pace and diet contribute to the longevity of Ikarians, with one in three making it to their 90s. The people of Ikaria tend to relax mindlessly through gardening, walking to a neighbor's house or playing late night domino games. Through the games and socializing, Ikarians are able to create connections with others. Studies have found that having a strong social network is part of living a healthy life. Their faith also aids in their longevity, as most Ikarians are Greek Orthodox Christians. While practicing calls for fasting almost half of the year, it cuts about 30 percent of calories out of the normal diet — the only proven way to slow the aging process in mammals. Lastly, almost all Ikarians drink goat milk as it provides potassium and the stress-relieving hormone tryptophan. 

5. Loma Linda, California

A community of an estimated 9,000 Adventists who live in Loma Linda, California put the US on the blue zone list. Adventists live 10 years longer than other Americans. Their beliefs, their volunteering, diet, exercise and fellowship add years to their lives. The Seventh-day Adventist Church encourages and provides opportunities for its members to volunteer. Through volunteering, many are able to focus on others and this allows Adventists to ward off depression. Their well balanced diet of vegetables, fruits, legumes and lots of nuts is influenced by the Bible. Adventists cite Genesis 1:29: “And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in which is the fruit of a tree yielding seed; to you it shall be for meat.” They also avoid smoking and drinking, a healthy habit that will help prevent future health issues. Many Adventists go on daily walks or participate in low intensity exercise. Their active bodies can stay consistently strong. Adventists’ time spent with like minded people who support their habits is what continues to make them some of the longest living Americans.
