Besides getting enough calcium and vitamin D, protein is also a particularly important factor in bone development. Crops in Europe and America are different from those in Asian countries. They take barley and wheat as their main food crops and are rich in protein. In Asia, rice is mainly grown, mainly carbohydrates.

Since modern times, European and American countries have implemented the animal husbandry mode of large pasture grazing and mechanized management, with a vast land and few people, and animal husbandry and fishery are generally developed; Because Europe and America have a large population and poor economic conditions, most Asian countries are operated by small farmers, and animal husbandry and fishery are not as good as Europe and America. Therefore, the quantity and variety of meat and dairy products on the white table are better than those of the yellow race, and the yellow race consumes less protein than the white race.

Some yellow people also suffer from lactose intolerance and cannot digest dairy products well. It is precisely because of the habit of the yellow race eating rice as the staple food that they consume the most carbohydrates that can quickly replenish energy, and the intake of protein, minerals and vitamins is far less than that of whites, which leads to the gap between the yellow race and whites.

Secondly, there are geographical and environmental factors.

From the Chinese perspective, northerners are usually taller than southerners. The height of men in North China and Northeast China is generally above 1.72cm, and the average height of women is also above 1.62cm, ranking among the best in China provinces. In southern provinces such as Guangxi, Guizhou and Hunan, the height of men is below 170cm, and the average height of women is even below 160cm. The difference between northerners and southerners is equivalent to the difference between whites and yellow people.

Because of the cold climate, people living in high latitudes are more likely to stimulate the secretion of growth hormone. Because of the heat in low latitudes, people here need less body surface area to help dissipate heat, so people are shorter.

At the same time, people tend to eat more food because of the cold and fast calorie consumption, so they get more nutrition every day.

Due to the influence of the cold climate, these white people are generally taller than the yellow people.

It is under the influence of diet structure and geographical environment that whites gradually evolved to be taller than yellow people.

China has a promising future.

However, recent data also show that the average height of China people is increasing rapidly.

19 18 years, the average height of men in China is only 160cm, and that of women is 149cm. It took only a hundred years for the average height of China people to increase 10cm.

If compared with Shandong Province, which is the highest in China, the average height of men is 175.44cm, which is not far from that of the United States, Britain, Poland, Spain and Italy, and the average height of women is 169.45, which is closer to Latvia, which ranks first in the world.

This is precisely because of the influence of China's rapid economic development. Due to the development of animal husbandry, China has a larger supply of meat and livestock, providing more and more meat for people. At the same time, economic development has improved people's living standards and enabled people to consume more kinds of meat and dairy products.

I hope that in the near future, the height of Chinese people can be further improved, the gap between modern whites and us can be shortened, and the level of whites can be caught up. Looking forward to your attention to our official WeChat account? Yuan Shi? )
