Yumi Yamamoto, a longevity researcher, listed four secrets from Japan's longest-lived people, such as eating until 80% full or keeping your back straight.
Yumi Yamamoto, research director at LongeviQuest, an organization that verifies the ages of the world's oldest people and collects information about them, said the organization has verified four supercentenarians this year who are over 110 years old, according to a December 5 Business Insider post. Among them is Fusa Tatsumi, who celebrated her 116th birthday in the spring and is the oldest person in Japan.
LongeviQuest has identified 269 people over 110 years old in Japan, many of whom live in Okinawa, one of the so-called Blue Zones where the number of people living over 100 is unusually high.

Like other Blue Zones, long-lived people in Japan tend to eat less meat and spend more time with family. But they have other specific habits that are more specific than some countries, according to Yamamoto.
"The Japanese have a saying: eat until you're 80% full , leave room for the end of the meal," said Yamamoto, the great-granddaughter of Shigeyo Nakachi, who was the second oldest person in Japan when she died in 2021 at the age of 115.
According to animal studies, this habit helps Japanese people be conscious of their diet, limits calories, reduces inflammatory diseases and is beneficial for longevity.
The average daily calorie intake for a person in the Okinawa Blue Zone is only about 1,900, lower than the 2,000 calories recommended by the US Food and Drug Administration.
One of the biggest lessons Yamamoto learned from talking to long-lived people was "don't do anything in excess, do everything in moderation ."
Kane Tanaka, the oldest Japanese person in history, lived to be 119 years old and loved Coca-Cola but only drank one bottle a day.
"He's not an addict, nor does he drink too much. This is common in Japan. Japanese people eat a balanced diet and don't overeat," Yamamoto said. "That applies not only to food but also to lifestyle habits like staying up late."
Experts agree that snacking in moderation can help make healthy eating more sustainable. This approach is known as the 80/20 rule (eating healthy 80% of the time and being more flexible in the remaining 20%).

Yamamoto said that in Japan, people often exercise to the radio . Since 1928, a radio program has guided listeners through 5-minute exercises every day. Yamamoto tries to exercise to the radio every morning like the long-lived people in Japan.
Many studies show that short periods of high-intensity physical activity reduce the risk of cancer and heart disease, thereby improving longevity.
Most Blue Zone long-lived people do not go to the gym but incorporate exercise into their daily lives, such as walking, climbing stairs, or playing group sports to socialize and exercise.
Yamamoto says body posture is also important. Her great-grandmother always kept her back straight . "I noticed that centenarians and centenarians in Japan always kept their backs straight, very disciplined and strict with themselves," she says. "As humans, we tend to hunch over a little as we get older, but Japanese seniors always keep their backs straight."
Research shows that good posture keeps the body comfortable, prevents pain and helps functions function properly.
