According to one statistic, the average height of people over 40 in China is higher than that in Japan, but people under 40 are not as good as Japan. The reason is that Japan was seriously short of food after World War II, but later the economy developed, paying special attention to nutrition and having a high understanding of balanced nutrition.
Economic improvement does not mean good nutrition. At present, due to malnutrition, the death toll is higher than any infectious disease. Statistics show that the economic losses caused by poor health are as high as more than 30 billion yuan.
The main causes of malnutrition are low nutrition awareness and insufficient nutrition knowledge. I think that people eat when they are hungry and eat whatever they like, but I don't think that eating is also a science.
Nutrition is a manifestation of a person's cultural quality, so how to use food and keep healthy depends on your basic nutrition knowledge. There is no bad food, only poorly matched food. The Ministry of Health announced eight principles of national diet: first, the food is diverse, mainly cereals; The second is to eat more fruits and vegetables; The third is to eat milk and soy products regularly; Fourth, eat proper amount of fish, poultry, eggs and lean meat, and eat less fat and meat dishes; The fifth is to master your appetite and maintain a proper weight; The sixth is to eat something light and less salt; The seventh is to limit drinking and not to drink too much; The eighth is to eat clean, hygienic and non-perishable food.
In addition, according to the actual situation of China people, the Nutrition Society of China put forward a pagoda for residents' dietary food, which is divided into five layers: the first layer is the bottom of the pagoda, which is cereals. Various foods contain more, and light manual workers have 500 grams per day; On the second floor are fruits and vegetables. Ordinary people eat 400 ~ 500 grams of vegetables and 0/00 ~ 200 grams of fruit/kloc-every day; The third layer is animal food such as fish, meat and eggs. Generally, 200g of fish, 50-100g of meat and 20-50g of eggs; The fourth layer is milk and milk. The average person drinks 250 ~ 500ml every day, and the fifth layer is salt and sugar. The daily intake of salt should not exceed 6 grams, and the daily intake of sugar should not be too much.
I hope everyone will pay attention to nutrition, reasonably match meals and be a healthy and progressive person.
