Want to live to 100? Japan’s centennials have the secret to longevity

What if you could live to 100 in reasonably good health? There are five so-called ‘blue zones’ around the world where people are living substantially longer and healthier lives than the global average. One of them is the island of Okinawa in Japan.

In Okinawa, 68 out of every 100,000 people are over 100 years old, according to data provided by 'Science Direct'. So, what are these elders’ secrets to longevity?

For life expectancy in Okinawa to be so high, in addition to diet, other factors such as climate, environment, and the healthy lifestyle of its inhabitants or genetics itself have an influence.

However, the inhabitants of the Japanese island have made it clear that food is key to living as long as possible and they take extreme care of their diet.

The Okinawan diet is based on vegetables, soybeans and medicinal plants such as turmeric or mugwort. Added to this are foods that they occasionally consume such as fish, seafood, lean meat, seaweed or fruits.

What they don’t eat also matters, such as refined sugars, ultra-processed food, sausages, nuts, poultry, many seeds or dairy products.

According to 'Heathline' this type of diet, low in calories and high in carbohydrates, is perfect for prolonging life expectancy as much as possible: 85% carbohydrates, 9% proteins and 6% fats. The ratio is 10:1 carbohydrates to protein. And the protein they eat is of animal origin, such as seafood or red meat.

According to the aforementioned media, this diet is ideal for controlling weight, but also for preventing diseases, as it is full of antioxidant foods. The question is, is this diet safe?

The answer is yes. And this is corroborated by a study published in the 'National Center for Biotechnology Information', which links the absence of saturated fats and sugars to living longer and better, since their consumption is associated with heart problems, obesity, diabetes or cancer.

On the one hand, the sweet potato provides fiber, calcium, potassium, carotenoids and vitamin C. Meanwhile, the melon prevents degenerative diseases, in addition to helping with constipation and reducing the risk of chronic diseases linked to aging.

On a comparative level, the closest thing to the Okinawa diet is the Mediterranean one, with the difference that Okinawa belongs to the 'Blue Zones', where the population lives the longest on average in the world.

Today, Okinawa has the highest life expectancy in the world, with almost all of its inhabitants exceeding 90 years of age. The following places follow Okinawa in the longevity ranking: Icaria (Greece), Sardinia (Italy), Nicoya (Costa Rica) and Loma Linda (USA).

To complement their diet, the people of Okinawa also add other cultural and social elements that help raise life expectancy to unsuspected limits.

For example, limiting the time of solitude, enhancing the circle of friends that each person shares until their old age. It is what they call 'moai' and is completed with 'yuimaru' which is the traditional practice of helping members of your community when they need it.

Finally, Okinawans, usually have an ‘ikigai’, the Japanese word for ‘sense of purpose’. One 102 year-old man’s ikigai was two prize bulls he took care of every day, according to a World Economic Forum article. But another person’s ikigai might be family or faith.
