14. Japan is the world’s most lived country.
For decades, scientists and researchers have studied Japan’s population because it is considered one of the world’s healthiest countries. They also have the longest average life expectancy with a low mortality rate with cancer and heart diseases. In the 1960s, it was the opposite; Japan had the shortest life expectancy with high mortality with many diseases, including stomach cancer. However, decades of medical research, better healthcare, and a population taking better care of themselves have made the difference to lower rates. One of the most significant lifestyle changes the population did was being more active and eating healthier.

Japan’s diet of fish, vegetables, and low sugar drinks might be the key for the long life expectancy. The lower numbers are thought to be because of a low prevalence of obesity, with a low intake of red meats and saturated fatty acids. They also spend time eating lots of fish, plant foods like soybeans, and low-sugar drinks like green tea. An increase in animal foods, like dairy products, and a decrease in high salty foods helped decrease mortality for other diseases like cerebrovascular ones. It helped with high blood pressure and reduced the chances of stomach cancer. A diet with plant food and fish, a modest quantity of dairy, and being active were the key to a healthier population.
