Children grow up to be weaned off, which is our traditional eating habits this practice is not scientific. Studies have found that weaning affects calcium uptake to a certain extent and bone development shortly.
A six-month follow-up survey of 474 7-year-old and 9-year-old pupils in Shenyang was conducted by the School of Health of China Medical University. It was found that the height of students who drank 400 ml milk per day increased by 0.72 cm and 0.46 cm, respectively, compared with those of the control group who did not drink milk. Also, the weight and bone mineral density of the children who drank the milk increased significantly.
The main terrain of Europe is plain, with a small population and a large area. The climate is mainly temperate marine climate, which is suitable for forage growth and animal husbandry development. In the areas where animal husbandry develops relatively fast, cheese production develops relatively fast. (Typically cheese-rich Western European countries: France, Italy and the Netherlands)
European latitude is higher, dairy meat food is what high protein foods and calorie, which can quickly provide energy for the body to withstand the cold. Animal husbandry produces a large amount of fresh milk, which can not be consumed, making cheese for a longer time to preserve. The more you do, the bigger you get, and eventually, it becomes indispensable to the whole people from the Royal family. As a result, Europeans rely on dairy meat.
Genetically speaking, we can say that the Chinese around you are lactose intolerant.So we should provie the lactose intolerant treats .Both in Europe and Asia, primitive humans were lactose intolerant genotypes. High lactose tolerance is a characteristic that has evolved gradually in human milk-drinking history, which is not very long.
About 11,000 years ago, herdsmen in West Asia domesticated dairy animals (sheep) and began using dairy products. But the genes for lactose tolerance did not appear in Hungary's vast, fertile plains until about 7,500 years ago. To reduce the problem of lactose intolerance, the ancient nomadic people invented various fermented dairy products, such as yogurt, cheese, through lactic acid bacteria fermentation, part of lactose into lactic acid bacteria.
After several thousand years of evolution, lactose tolerance has reached over 80% in Europe, North America, and Central Asia. In Poland, this evolution from 0 to 80 percent took only 130 generations. The explanations given by evolutionary biologists are:
People with lactose tolerances genes are more likely to consume nutrientsthey should test for lactose intolerance before drinking milk , and their offspring are 19% higher than those with lactose intolerance. Lactose tolerance genes have thus become "the most powerful genes found in the genome so far".
So why don't the Chinese have this gene? Because we don't drink milk. So there is no such powerful natural selection.
In the Neolithic Age about 10,000 years ago, the ancestors of different parts of Eurasia began to produce agricultural products and domesticate livestock. The purpose of domesticating livestock is to obtain a stable and reliable source of food. Apart from dogs, most domesticated livestock is used for food.
The climate in West Asia is dry and hot, and the terrain is mainly plateau and mountainous areas, which is suitable for the development of animal husbandry. Cattle and sheep have become the main livestock in West Asia. The Chinese civilization originated from the alluvial plain of the Yangtze River Basin in the Yellow River, suitable for grain cultivation, and the pig with the wider diet became the first choice *. Compared with cattle and sheep, pigs produce little milk, have short lactation period, and have difficulty in collecting (nipple). They are not qualified dairy animals. Killing meat is more cost-effective. Buffalo and buffalo, which helped farm, did not appear on a large scale until the Bronze Age, four or five thousand years later than in Western Asia.
Because of the differences in dietary habits, it also leads to differences in body shape. Europeans are indeed much stronger than Asians in eating meat and drinking milk. This also explains the low-carbon and high-protein diet mode advocated by the fitness circle at present, that is, the way foreigners eat, so the form of fitness meals is also the majority of Western food.
The human skeleton is the "warehouse" of calcium storage, which is rich in stock and benefits all one's life. In the past, experts generally believed that before the age of 30 is a good time to supplement calcium, but now they emphasize that childhood is the most important! Nowadays, many young women do not pay attention to drinking milk at ordinary times. When they enter pregnancy or lactation, they drink milk in large quantities. They think that this can meet the growing needs of fetuses or infants, and also reduce the excessive loss of calcium from mothers.
However, the study of "Nutrition of milk to breast-feeding mother's bone" in Tongji Medical College of Huazhong University of Science and Technology reveals that this is not helpful, because the bone quality of those who increase milk consumption is not better than those who do not drink milk, and women who have milk drinking habits have the least bone calcium loss. The study further confirmed that the effect of drinking milk on improving calcium nutrition is long-term, and can not be a quick success and instant benefit.
Relevant experts stressed that in the future, we should not publicize "weaning" unilaterally, but cultivate the habit of drinking milk for life. From nutrition and health improvement, "drinking milk every day, benefiting for life, health for generations, national prosperity" is our goal.
