After Huangshi taught Ling'er how to measure her body, the measurements of women on the island, as well as several other basic lengths, such as the length of clothes, sleeves, trouser lengths, and shoulder widths, were all counted a day later, and dozens of copies of white Yingying's paper were filled with tables and numbers.

Huang Shi flipped through it casually, most of the body data of these women in the Ming Dynasty were very "miserable", at a glance, the height was below 1.50 cm, the only few people who were exceeded, Huang Shi looked at it, that is, Ruyi, Qu'er them, but unfortunately their height did not exceed 1.60 cm.

In addition to them, Hong'er is the tallest, reaching 1.65 centimeters, taller than Jiang Da and Jiang Er, and this height advantage has protected her safety for a certain period of time. And Ling'er is only about 1.55 meters, which is slightly shorter than Jiang Er'er.

It can be seen that these are all because of the nutritional and genetic factors that have played a great role in it since childhood, but there are also regional factors, as a homeless person from the north, Hong'er's skeleton is much taller than several other little girls of the same age.

According to these data, Huang Shi couldn't help but think of a topic on the Internet, that is, how tall the ancient Han people were, some people said that their average height is higher than that of modern people, Huang Shi really doesn't believe in this conclusion, after all, in addition to the genetic factors of both parents, the most important thing is the nutritional level, and the intake of protein and other nutrients of modern people is not comparable to ancient people.

In human adolescence, that is, the golden period of growth and development, it is the most important to correctly supplement adequate nutrition and supplement the nutrition of bone tissue, because it affects the degree of growth and development of bone tissue.

In the human body's bone tissue, in addition to calcium accounting for 30% and phosphorus accounting for 16%, the rest is almost bone collagen and water. Therefore, supplementing calcium, phosphorus and collagen can effectively promote the growth and development of bone tissue.

Calcium supplementation alone does not make much sense, and phosphorus supplementation is also needed, although the phosphorus content in the diet of the current society is not low, and it seems that there will be no phosphorus deficiency problem. However, almost all phosphorus in plants exists in the form of phytate phosphorus, and the human body also lacks phytase to decompose, so the absorption and utilization of these phosphorus by the human body is not high.

This is in the modern society, even if almost every household has fish and meat every day, it is still necessary to advocate the same calcium and phosphorus supplements, not to mention that in the Ming Dynasty 500 years ago, people at this time were still mainly based on grain food, that is, large families, their servants can have three or four opportunities to eat meat all year round It is very good.

Therefore, when Huangshi first arrived in this era, most of the people who saw it for the first time were shriveled and thin, with dull skin, without a trace of luster, and of course, more of them still looked like they didn't even have flesh on their breasts and buttocks, so Lao Huang was extremely envious of those who could find fragrant grass within 10 steps through their predecessors.

The foundation and quality of this kind of population was naturally not what Huangshi wanted, so from the day they came, he arranged their nutritional diet plan. It is a soup made every day, made from frozen bones bought from modern times in Huangshi, or big fish caught from the offshore waters of Dongluo Island, and the fish bones after the fish meat is removed.

These two kinds of bone broth are very good, according to Dr. Chen Lishui, it can boil out some bone collagen, although it does not dissolve much calcium and phosphorus, but it is very economical to do so, and there are no toxic side effects. In addition, the large amount of protein rich in the eliminated fish meat, and then eaten in a braised or steamed way, truly conforms to the basic health principle that medicine is not as good as food supplement.

Maybe it's because they're already at the bottom, so they haven't gone through a month of food supplements, and those who have become adults and stereotyped, although they can't change in height anymore, the flesh in their bodies and the luster on their skin are increasingly visible. And although the simple temperament has not changed, there has been a earth-shaking change in spirit.

And those girls who have not yet gone through puberty, the changes are naturally more amazing, they are all taller and taller, and their bodies have become round and jade, they seem to have become slim overnight, full of vitality.

……

It can be seen that height does have a lot to do with living conditions, as long as there is enough meat and rice to make people full, even if there is no modern luxury nutrition, it is no problem for ancient people to grow taller, but it is a little ridiculous to talk to ancient people who are taller than modern people.

Because the word ancient, starting from ancient chronicles and ending until 1840, can be counted into the scope of "ancient", and some people who do not learn and do not consider the difference in ancient units of measurement, according to the romance novel, came to the height of Zhang Fei at the end of the Han Dynasty 1. 85 meters, Guan Yu is 2 tall. 10 meters, even ordinary horses can't move the conclusion.

Some people even put forward the gene theory in a hurry, saying that when the Han people were strong, the big man was valued, so the tall gene was the dominant gene, and it was more likely to be developed; In previous invasion massacres, shorter people were considered less threatening by the alien race and were much more likely to survive, and the genes of the short Han people became the dominant genes due to human factors.

In fact, according to scientific research, the height of the ancient Chinese began 5 or 6,000 years ago, and until 1949, their height has been on a downward trend during this period.

Through the analysis of Chinese human bone samples in the middle and late Yangshao period, which was five or six thousand years ago, to the Tang Dynasty, between 618 and 907 AD, it is estimated that the average height of men in the Yangshao period was 1 according to the international formula for measuring human height with femurs. 69 meters to 1. 70 meters, 1 for women. 63 meters, these two data are very similar to the average height of modern Chinese, indicating that people's nutritional status was very good at that time.

The study also showed that after the mid-to-late Yangshao period, the height of Chinese men continued to decline slightly, gradually leveling off by the Han Dynasty, while women continued to decline, which was related to the fact that men consumed more meat than women. Even the Tang Dynasty people in their heyday were not as tall as the average of the Yangshao period.

Because for millions of years in human history, 97% of the time was hunting and gathering for a living, often migrating, and rarely farming. Basically, you eat whatever grows on the ground, and you eat whatever you hunt. This way of life helps humans to maximize the use of resources in the natural environment, and does not rely entirely on a single food, so as to obtain better nutrition. This is why people who lived 5,000 years ago were not as poor in nutrition as modern people think.

In the middle and late Yangshao period, due to the intertwined effects of climate change, agricultural development, population increase and other factors, the height of Chinese began to decline. Especially 5,000 years ago, when the earth entered the Xiaoice period, the climate became colder, the types of food grown by people decreased, and the nutritional value of the food ingested decreased, which led to the decline in the height of Chinese.

Since then, with the development of agriculture and the improvement of the level of concentrated planting, the types of food have become less and less, the source of food for ancient humans has become narrower and narrower, and the nutritional status has naturally become lower and lower, and the height has also declined, until the period after the liberation of China, it has begun to bottom out.

In fact, this phenomenon exists not only in China, but also in the whole world, because the scientific community also generally believes that the formation of agricultural society and the way of life of fishing and hunting were replaced by agriculture 6,000 years ago, which caused the decline in the average height of human beings.

Professors at the University of Oxford, UK, after analyzing the bones of thousands of ancient human males excavated from Denmark, Sweden, Norway, the United Kingdom and Iceland, found that the average height of adult human males reached an average maximum of 1 between the 9th and 12th centuries AD during the Middle Ages, between the birth of modern Homo sapiens 100,000 years ago and the mid-20th century. 73 meters, then gradually shorter to lower.

By the 18th and 19th centuries, on the eve of the Industrial Revolution, the average height of adult males in Europe had fallen to 1. 67 meters, a decrease of 6 centimeters from the 9th to 12th centuries. It was not until the middle of the 20th century that the average height of human males returned to its maximum value between the 9th and 12th centuries.

Huang Shi casually flipped through these tables that recorded the data of women on the island, while thinking about these marginal things, and then sighed with the scientific spirit of various "civil science".

A few days later, his friend Zeng Youyi brought him hundreds of shirts and uniforms from his brother's garment factory, which Lao Huang had specially ordered to order.

"Why are the names of these female workers in your company so weird?" When he was flipping through the list, Zeng Youyi felt very strange, because except for a few names, the other names were dirty and scummy, and those special names made him feel as if a smell of "Dream of Red Mansions" was coming to him.

"What's wrong?" Huang Shi didn't notice this, he had noticed the height stats before.

"Look at them, what are they called, Ruyi, Snow Sweeping, Snow Goose, Purple Juan, Bijin, Ping'er, Qu'er, Cooking Wine, ......" Zeng Youyi was on the list, and he pointed out several names with the characteristics of the times.

"Ugh." Huang Shi was speechless for a while, thinking to himself, this is a big negligence, these people were originally servants and maids in Jiangjiazhuang, and the rules for naming are naturally based on the way the girls are named, should they change their names after going back.
