Mongolian traditional food can be divided into three types, the first is meat products (red food), the second is dairy products (free food), and the third is milk drinks. Mongolian people have a special diet. Diet is divided into two seasons, summer and winter. Summer is from April to 10, and the main food is dairy products. During this period, I ate less meat. The main thing is that you need to eat meat to increase fat and resist the cold in winter. After several months of accumulation, dairy products need to be digested and absorbed in summer, which is very beneficial to health. Mongolian children eat dairy products since childhood, but it is forbidden to eat too much meat, otherwise it will be bad for their health. So in ancient times, few Mongolians suffered from hepatobiliary and gastrointestinal diseases. Mongolians have long known how to eat scientifically and how to maintain themselves. There is a Mongolian proverb: Eat breakfast by yourself, share lunch with friends, and give dinner to the enemy. Its meaning is similar to China's "Eat well for breakfast, eat well for lunch and eat less for dinner". The unique food culture has created the strong physique of Mongolians. In recent years, with the changes of society, the diet structure, eating utensils and eating styles of Mongolians have changed under the influence of the West. Pastoral areas, which are deeply influenced by traditional food culture, still retain some ancient food culture, but it may be influenced by the Soviet Union and the West. Now Mongolian food and western food have become a new dietary pattern. In cities, people's eating patterns are completely westernized. There are many big hotels and small restaurants in Ulaanbaatar, the capital of Mongolia. Their dining environment, tableware and serving procedures are completely in line with European standards. The dining environment is exquisite, and the tableware is all knives, forks and plates. Although there is milk tea and Mongolian food in small restaurants, there is no difference between the structure, mode and tableware of Mongolian food and western food. The same is true of ordinary people. Besides salad, soup and set meal, bread, cream, butter and jam will be prepared on the table. Primitive Mongolians and non-Mongolians usually divide human beings into black, yellow, white and brown. Caucasians, also known as Caucasians, are mainly distributed in Europe; Yellow race, also known as Mongolian race, is mainly distributed in East Asia. At the end of the twentieth century, biologists found that Neanderthals were not the ancestors of modern Europeans, so it is not difficult to deny that Beijingers were the ancestors of modern East Asians. In recent twenty years, the research of physical anthropology, especially the progress of fine-grained DNA and Y chromosome, shows that human beings originated in Africa 200,000 years ago. Modern people entered Eurasia from Africa about/kloc-0.0 million years ago, and one of them began to enter East Asia from Southeast Asia about 60 thousand years ago and gradually evolved into a Mongolian race. Autosomal studies also support the above conclusions. There are not many human bones found in Paleolithic Age in East Asia, especially 5000-65438+ 10,000 years ago. Neolithic human bones are very close to modern Mongolian bones and should belong to Mongolian race. They are in the process of the formation and differentiation of Mongolian race, which is generally called primitive Mongolian race or Mongolian race formation. In the Bronze Age, Indo-Europeans appeared in East Asia. From the Paleolithic Age to the Neolithic Age, East Asia is the main distribution area of Mongolian race, and it is not a problem that Han and Mongolian generally belong to Mongolian race. The problem now is how to understand the non-Mongolian ethnic composition of Mongolian and Han nationality. Recent research shows that non-Mongolians in East Asia not only exist, but also have a larger proportion than most people think, and the time is earlier than some experts estimate. About four thousand years ago, when the Xia Dynasty was founded, Indo-Europeans began to enter East Asia one after another. After a comparative study of Chinese and Indo-European languages, Edwin G. Edwin G. Pulleyblank pointed out that Indo-European languages entered China no later than India, and Yueshi, Wusun and Tuholo are all Indo-European languages. Yu Taishan echoed at a distance, saying that it is not excluded that the heroes, the fish, the dog, the ghost, the Fang and the Xiongnu belong to Indo-Europeans. In fact, Sima Qian had a clear meaning at the beginning of Historical Records Biography of Xiongnu: "Xiongnu is also a descendant of Xia Houshi, called Chunwei". Wang Guowei believes that ghost face, Kun Yi, stubbornness and Xiongnu come down in one continuous line. Hu Houxuan believes that the Turkish side belongs to the Xia nationality. Xu Zhongshu and others have long pointed out that the heroes of the western regions and the heroes of the Central Plains belong to the same family, and before the month branch, they were Yu; Wang Jingru also proved that spitting fire in summer.
