Japan has been an aging society for many years. Health preservation and life-extending habits have always been hot health topics. Okinawa Prefecture, Nagano Prefecture, Shimane Prefecture, Miyazaki Prefecture and other well-known “longevity prefectures”, which foods do residents usually spend the most money on? Hisao Akitsu, a well-known general internal medicine physician known as the “King of Medical Miscellaneous Medicine” by the Japanese media, analyzed the relationship between diet and health based on the latest “Household Survey” of the Ministry of Internal Affairs and Communications and the food expenditures of residents in each ward. He found that 4 types of food may It’s the key to longevity!
Okinawa Prefecture ranks first in average life expectancy following the age of 65: Tofu is my favorite! “Soy Isoflavones” Reduce 3 Cancer Risks
Among the various administrative regions, the most eye-catching is Okinawa Prefecture, which ranks first in the average life expectancy following the age of 65. Okinawa women have a low cancer attack rate. According to a survey by the National Cancer Research Center of Japan, even colorectal cancer and lung cancer, which cause the most cancer deaths among Japanese women, have the lowest cancer attack rates in the country for Okinawa women.
Hisao Akitsu analyzed that the amount of tofu purchased in Okinawa ranks first in Japan. Local people often use it for stir-fry or as an ingredient in miso soup and eat it in large quantities. Tofu contains soy isoflavones, which have similar structures to female hormones. Studies have found that they can reduce the risk of colorectal cancer, lung cancer, and breast cancer.
Ingesting soy isoflavones through tofu and other soy foods has many benefits. Nutritionist Li Wanping once wrote on Facebook that research has found that the active factor “genistein” in soy isoflavone foods can improve glucose metabolism and lower insulin. impedance.
In addition, because the structure of soy isoflavones is similar to estrogen, many people are worried that if it is absorbed in the diet, will it cause breast cancer? In fact, moderate intake of soy isoflavones can help balance the body and reduce the risk of breast cancer and breast cancer recurrence. There is even a Japanese epidemiological study that found that the intake of soy isoflavones is related to a reduced risk of lung cancer, and clearly mentioned that it is derived from soy foods.
Nagano Prefecture ranks second in average life expectancy following the age of 65: The amount of vegetables purchased is extremely high!Potassium helps excrete sodium and protects cardiovascular system
Nagano Prefecture, which has “the second highest life expectancy following the age of 65”, is also known today as a healthy and longevity prefecture. However, in fact, residents of Nagano Prefecture have not always lived a long life. Since Nagano Prefecture residents are accustomed to eating local dishes such as pickles, their intake of sodium content is very high. According to statistics from Showa 40 (1965 AD), Nagano Prefecture ranked fourth in the country in terms of salt intake. Not only did it have a high number of patients with high blood pressure, but its death rate from stroke was also the first in the country. Male life expectancy was only ranked ninth in the country. , the life expectancy of women is only 26th in the country.
Later, fortunately, enthusiastic doctors promoted salt reduction campaigns in Nagano Prefecture, raising overall residents’ health awareness, and coupled with clever tips such as eating more vegetables, the average life expectancy was gradually increased and Nagano Prefecture became a well-known healthy county. Today, the average daily vegetable intake of Nagano Prefecture residents is as high as 379g, far exceeding the national average of 301g in Japan, and 1.5 times that of the counties and cities with the lowest vegetable intake.
Hisao Akitsu analyzed that although the local diet in Nagano Prefecture does tend to consume more salt due to pickled vegetables and other dishes, even following the salt reduction campaign, the current amount of salt purchased is still the third in the country; however, due to the excessive intake of various types of Vegetables, and vegetables are rich in potassium, which can help the body excrete excess salt, help lower blood pressure and protect cardiovascular systems. In the long run, the disadvantages of higher salt intake will be offset.
Shimane Prefecture ranks third in average life expectancy following 65 years old: clams can protect the liver; mackerel reduces the risk of heart disease
On the other hand, Shimane Prefecture, which has “the third highest life expectancy following 65 years old”, is also praised for having the highest number of centenarians in Japan for 11 consecutive years, and nearly 90% of those over 100 years old are women.
Hisao Akitsu analyzed that Shimane Prefecture ranks first in Japan in terms of clam purchases. Clams are rich in ornithine, an amino acid that can improve liver function. In addition, the county ranks second in the country in terms of the amount of mackerel purchased. Mackerel is rich in Omega3 fatty acids such as DHA and EPA, which can help blood flow smoothly. It not only has the effect of reducing triglycerides and preventing dementia, but research has also found that it can reduce the risk of diabetes and heart disease. The mortality rate of women from diabetes and liver disease in Shimane Prefecture is significantly lower than that in other counties and cities, which may be related to this eating habit.
What’s special is that Miyazaki Prefecture, which spends the most money on mackerel in Japan, ranks 22nd in average life expectancy following the age of 65, but has a “healthy remaining life” (the age at which one can live a healthy life without being bedridden or being cared for). ) ranks in the top 3, presumably because the Omega3 fatty acids in mackerel can help blood flow smoothly.
Omega-3 fatty acids are nutrients that the body cannot produce on its own but are very important to the human body. Nutritionist Lin Yuwei once pointed out in an article that Omega-3 fatty acids can protect eyes, reduce fatty liver, joint inflammation, triglycerides, and maintain skin. It is complete, reduces dryness and itching, improves depression and improves brain degeneration. It is recommended that people consume an appropriate amount of seafood containing Omega-3 fatty acids in their daily diet.
