As we all know, Japanese people are generally short. What is the Japanese diet like? Japan is an island country. They never lack seafood, so they can get a lot of calcium from food. Calcium plays a great role in the growth and development of human body. Everyone knows that people who lack calcium will get rickets, osteoporosis, short stature and so on. Obviously, the short stature of Japanese people is not caused by calcium deficiency.
Many people think that the taller Europeans are, the better, because they like to eat beef and cheese. Yes, beef and cheese give Europeans a good calcium supplement, while China people prefer to eat pork, but they don't get as much iron as Europeans. In addition to coastal cities, people in inland areas of China are still short of calcium.
But think about it, China is a vast country, and the height of China people also exists? High in the north and low in the south? Fashion. Why is this? Is it just the difference in diet between North and South? Of course not. What is the height of China people if there is seafood in coastal areas to supplement enough calcium? High in the east and low in the west? Yes, the reason why northerners are generally tall is because of different races. In fact, most ethnic groups in northern China belong to Mongols, and some are descendants of Caucasians. Mongolians and Caucasians are taller than other races. It is said that Shandong people migrated from the descendants of ancient Caucasians, so China has the saying of "Shandong man". It's not because Shandong people have seafood to eat or lack calcium, but because the races are really different.
Even if China grew up in a foreign country and his diet was the same as that of foreigners, he wouldn't grow taller. Because height has nothing to do with diet, but more to do with race.
