The average life expectancy of Japanese people is 87.71 years for women and 81.56 years for men, which is the data for 2020. Compared to 2015, women increased by 0.73 years and men by 0.81 years.
Japan not only has many long-lived elderly people, the average life expectancy is also very high, Japan's Okinawa is famous in the world, is the longest average life expectancy in the whole of Japan, where there are more than 400 centenarians, with the title of "land of gods".
The situation that arises is inseparable from the dietary relationship of the Japanese, or to be more precise, it is closely related to the control of the amount of food and the reasonable combination of diet.
There is an old saying in China: eat less, live longer, from the surface meaning, it is said that eat less, life expectancy is longer, this is the life experience summed up by the ancestors, but now it is left behind by people.
Every day big fish and meat, overeating, not eating, or eating too much high-calorie food, modern people have many diseases and unhealthy diets, so can you prolong your life after reducing the amount of food? An American study tells you the answer.
01
American studies have found that reduced meal intake is related to life expectancy
Biological scientists at a research institute in the United States have done relevant experiments on mice and monkeys and found that there is a certain relationship between the amount of food and the long life span.
The average lifespan of monkeys is about 20 years, and the study found that if the monkeys reduced their daily diet by 3% on the original basis, their lifespan could reach 43 years, and these monkeys did not show obvious signs of aging in behavior and appearance.
Through research scientists, it is understood that monkeys who eat about 30% less per day can live to a maximum of about 43 years old, which has far exceeded the average lifespan of monkeys, and there will be no signs of aging in appearance and behavior after 30 years old.
In the 20 years of the experiment, the mortality rate of monkeys who reduced their intake was about 15%, and the mortality rate of normal eating was close to 40%, which was a huge numerical difference that led scientists to believe that eating less could lead to longevity.
The authenticity of this study's conclusions still needs to be supported by many other research conclusions, not completely true, but eating too much and too much support will definitely bring damage to human health.

Eating too much causes a variety of diseases
1. Cancer
When the human body consumes too much protein or fat, it will increase the workload of the digestive system, and foods that cannot be digested well will remain in the intestine to produce toxins and even carcinogens.
In addition, eating too much and holding too much will cause the ability to inhibit the activity of cell carcinogenesis factors to decrease, increasing the chance of cancer.
2. Premature aging
The food eaten in the body is digested, metabolized, and oxidized, producing energy, but the body's oxidation reaction will also produce harmful free radicals, such as free radicals, which will lead to cell damage and arterial hardening, thus inducing disease, aging, and even death.
The more energy the human body consumes, the more oxygen free radicals are produced, and the speed of aging of the human body will also accelerate, on the contrary, eating less can reduce the production of oxygen free radicals, thereby delaying aging.
3. Alzheimer's disease
Eating too much, the brain will produce the birth factor of fibroblasts, which will make fat cells and capillary endothelial cells enlarge, promote cerebral arteriosclerosis, insufficient supply of blood oxygen to the cerebral cortex, slow brain atrophy and brain function degradation, and eventually induce Alzheimer's disease, thereby shortening a person's life.
Japanese experts found that about 30% of elderly dementia patients have long-term satiety habits in their young adulthood.

Japanese longevity is related to "eating"!
The European Journal of Nutrition published a study of public health from the Graduate School of Medicine, Tohoku University in Japan, which analyzed data from more than 92,000 people and found:
The "seven types of foods that Japanese people eat" and "one type of food that they don't eat often" may be the secret of Japanese longevity!
The study evaluated participants' diets based on eight Japanese diet indexes, with higher scores indicating more Japanese eating habits. Using a validated 147 food frequency questionnaires, the researchers surveyed the eating habits of more than 90,000 people, with an average follow-up time of 18.9 years.
The results showed that participants whose eating habits were more Japaneseized had a lower risk of death. The risk of all-cause death, the risk of cardiovascular death, and the risk of death from heart disease decreased by 11% compared with those with the lowest scores on the 8 Japanese diet index.
The researchers concluded that the Japanese diet was associated with a reduced risk of all-cause death, cardiovascular death, and cardiac death. This may be related to the wholesome nutrients in the Japanese diet in seaweed, stains, yellow-green vegetables, fish, and green tea, contributing to a long and healthy life.
04
When eating, how much is the healthiest to eat?
The meal must be seven points full to be considered good.
If you want to effectively control weight, you must keep each meal only seven points full, and when you eat seven points full, the body can already get sufficient nutrition, and continuing to eat at this time will lead to excessive intake of nutrients.
Some people usually eat until they last, which is actually very detrimental to health.
When you find that your eating speed has become significantly slower, which is what we call "eating until seven points full", you feel that the food that was originally delicious has become less delicious, and you can quickly stop eating with a slight shift of attention.

The 3 rules of japanese health and longevity may be worth learning from
1. Eat less salt
Japanese people also eat very little salt, and their daily salt intake is less than half of Chinese.
As early as 1975, the Japanese government began to pay attention to the issue of national salt reduction and launched a series of salt reduction campaigns. Moreover, under the supervision of the World Health Organization, the Japanese are now paying great attention to controlling salt from all aspects of the diet.
2, love to eat deep-sea fish
When it comes to which country likes to eat fish the most, Japan can be said to be the last to be the best, because Japan is surrounded by the sea and is very rich in seafood resources, so Japanese people like to eat fish.
Fish is a high-protein, low-fat meat that is very good for good health. Many studies have proved that long-term eating of fish, especially deep-sea fish, can not only prevent cardiovascular disease, reduce cholesterol, but also prevent the occurrence of Alzheimer's disease.
3, like to bathe
Japanese people are very fond of soaking in hot springs, bathing on the one hand can keep the human body clean, develop good hygiene habits, on the other hand, soaking in hot springs can promote human blood circulation, play a role in health care, beauty, and have a very healthy effect on the body. #爱乐养生指南 #
