The Chinese diet has evolved over millennia from the ancient two meals a day to the current three meals a day. In fact, this traditional habit has not changed for a long time, and the literature reports that the general public has only started to adapt to three meals a day since the liberation. In ancient China, the average family only had a morning meal and a nursing meal, and since there was no night life at that time, basically they went to bed at night, so there was no dinner or night. It is documented that Chinese people gradually started to have three meals a day only after the Republic of China. With the popularization of education, schoolchildren at home had to go to school on time during the day, so they couldn’t eat and feed themselves as before, and parents had to change their lifestyles with the change of rhythm of their children’s lives. It is said that the children could bring a steamed bun to school every morning, and the adults slowly ate some breakfast with their children, and had lunch with them at noon. Later, the family has a TV, every day night life is getting richer and richer, three meals a day fixed, sometimes watching TV late, but also to eat some late night snacks. With the liberalization of everyone’s mouth, the diseases caused by the mouth into the increasingly prominent, such as diabetes, gallstones, kidney stones, hypertension …… Thus, the two-meal-a-day system was once again brought to attention. Famous writer and collector Ma Maidu wrote an article suggesting a two-meal-a-day system, the reason is: “People now three meals a day, people who go to work are nervous about breakfast, lunch conditions are not good to make up, dinner, if you do it yourself, but also tired, in short, for working people, three meals are not satisfactory. In fact, the custom of three meals was formed after the Song Dynasty, before the Tang Dynasty we ate two meals, the morning meal called “morning food”, the evening meal called “Asr food”, Han Yu’s poem lamented: the morning meal is not full of intestines, winter clothes to cover the iliac. At present, 8 hours a day at work, eat a meal in the middle, because eating this meal at least an hour of time wasted, the loss is not worth it. If you eat two meals, go to work at 10:00 a.m. and leave work at 4:00 p.m., you will have plenty of time to eat at both ends, which is good for your body and in line with the health concept of eating early and eating early at night. 6 hours a day to work high efficiency, energy concentration, uninterrupted will not waste time, the evening can also stimulate social consumption, the next day a late start also does not hinder, think about eating two meals is really a lot of benefits. 1, in the country, improve the employment rate, 30 hours of work per week than 40 hours of work theoretically improve 25% employment, so as to ease the employment pressure brought about by the delayed retirement; 2, improve social consumption, which will lead to a substantial increase in evening consumption, alleviate social conflicts; in the individual, eat two meals nutritious enough, eat three easy to obesity, increased disease, affecting life expectancy; 3, personal time to increase, you can free arrangements, such as study, which will improve the happiness index. Poor in the past, three meals are carbohydrates, animal protein intake is low, people are easy to starve, hungry and no spirit; and today big fish and meat and oil, eat more easily sleepy, also no spirit, the general people are sleepy after lunch, no efficiency; if changed to two meals a day, the country has improved efficiency, the people improve the pleasure of life, the whole nation’s health and good, three birds with one stone, why not?” Today’s medical research has proved that some people two meals a day has not caused nutritional deficiencies, but because of the intake of protein and other high-fat substances to reduce the workload of internal organs, beneficial to avoid the occurrence of some diseases. Some studies have shown that overeating at dinner is closely associated with diabetes, fatty liver, intestinal cancer, obesity, and high blood pressure and kidney stones. My view is the same, if you are obese and combined with the above diseases, or have a family history of these diseases, you may wish to ban dinner to try. If the moment can not control the first can do the following: 1, quantitative and not overeating; 2, eat dinner early, never go late; 3, dinner more vegetarian; 4, dinner less high calorie, high calcium, high fat and easy to bloat food. In short, learn to eat a good dinner, look towards health.
