There are even many friends who like to stay up late. They don't eat dinner, but just wait until the evening 1 1 to have a snack and dance and go clubbing with friends. This has put the cart before the horse with the development concept of "three meals a day", but these night cats feel that their bodies have not changed. Then, the question is, who clearly stipulates that people must eat three meals a day, and who clearly stipulates when to eat three meals?
In fact, "two-meal system" and "three-meal system" both occurred in ancient history. In ancient China, the system of two meals was adopted, and the time for eating was in the morning (7: 00-9: 00 am) and in the morning (15: 00- 17: 00 am). The two time ranges of eating are called morning food and morning food respectively.
As China was an agricultural country in ancient times, everyone followed the sun according to the life rule of "sunrise and sunset", so it was a very effective way to have dinner after dawn and shortly after dark. There was no need to light a lamp. After the sun had completely set, they went back to their rooms and fell asleep.
Because during the day, everyone has to work in the fields, and the farmland with pure human food is very large and the task is complicated, so young people don't feel warm at all, so as not to delay time. However, during the busy farming season, some women will take their cookies to the fields and give them to their hard-working husbands. Some men just take some food with them to solve the problem of food and clothing.
In addition, in ancient Chinese dynasties, the relevant provisions of the night ban were more or less ordered. It was not until the Song Dynasty that the food culture became popular, restaurants and pubs were open until late at night, and the curfew time was slowly revoked. Before that, catering only provided people with the energy to live and work hard, without nightlife culture. Just two meals is enough, and you can save firewood.
Of course, the key to the two-meal system is aimed at ordinary people. Royal aristocrats don't need to save firewood and food crops between meals a day, and they have various meals. It was not until the south of China gradually became rich that the daily diet of ordinary people changed from two meals a day to three meals a day. According to the description of "Qing Li paper money": "In China, the frequency of solar eclipse is generally three times a day in the south and twice a day in the north."
To be sure, from the Han and Tang Dynasties to the Song Dynasty, the change from the two-meal system to the three-meal system slowly affected most of the Central Plains, but it was not so obvious to ordinary people. At most, it is based on the fact that in the winter leisure and busy farming season, people eat their own meals and have a meal that is not the staple food at this time in the afternoon.
Later, during the Republic of China, European culture spread to China, and Europeans widely ate three meals a day, so this culture and art changed the vast majority of China people. Nightlife culture is getting richer and richer. People not only burn wood for cooking, but also have oil lamps for lighting at night. More and more things that are convenient for daily life have entered the daily life of ordinary people. Our life is no longer farming or doing business.
Three meals conform to the law of life and the law of intestinal digestion and absorption. The interval between meals is 4-5 hours, which is just the time spent on gastrointestinal motility ingredients. It is time for breakfast, lunch and dinner. If you feel hungry, you can eat the next meal, which has no pressure on your stomach and intestines.
On the other hand, three meals a day is in line with most people's work schedules. Breakfast is 7:00 am, lunch is 65438+ 02:00 pm, and dinner is 5:00 pm. After 10:00, it's time for everyone to relax slowly and plan to sleep.
Generally speaking, who can make it clear when everyone eats three meals? This is an increasingly rapid social development, and it is more and more convenient for its doctors and senior nutritionists who study health scientifically. In fact, in some remote places in China, people still keep the good habit of eating two meals a day, or follow the pace of the sun in their daily life. But for people nowadays, it is really difficult to eat two meals a day. How lucky you and I are to have a big meal.
