How does our grocery store differ from a grocery store, say, in Vietnam, Laos, Cambodia? The main difference is that in THESE countries you will not find milk on store shelves. They practically do not sell it there and hardly drink it. There is only one reason: milk is not assimilated by the body in the local population. The share of Ukrainians of those who are unable to assimilate lactose does not exceed 13%, and among Jews and blacks - 70-80%.
The Soviet geographer A. Petrenko, who traveled a lot in Asia, was extremely surprised that the locals completely ignore such a useful product as milk. Cows are not valued there, they are not milked, only the bulls that are used in the farm are in price.
Somehow, Petrenko decided to treat his Asian friends with milk. As a result, Cambodians developed severe stomach upset, diarrhea, vomiting, fever, and fell ill for several days. The problem is not in milk itself, but only in one of its components - milk sugar (lactose). Lactose is the only carbohydrate macrocomponent in the milk of almost all mammals. 100 ml of cow's milk contains 4.5 g of lactose. In general, as a rule, the more fat in milk, the less lactose. The peculiarity of lactose is that it is contained only in milk and for its assimilation a special enzyme is needed - lactase. It is produced by cells located on the inner surface of the middle part of the small intestine - here lactose is broken down and the products of its hydrolysis are absorbed: galactose and glucose.
What happens in the body of those who are unable to assimilate lactose? Undigested lactose is partially absorbed into the bloodstream and then excreted in the urine. But most of the lactose ends up in the large intestine, causing serious disruption to the digestive system. In some cases, this can even be fatal.
It was once believed that all peoples are equally capable of assimilating milk, and cases of its rejection were attributed to the individual characteristics of each organism. However, in 1965, Pedro Cuatrocascas, Theodore Beiles and Norton Rosenzweig (J. Hopkins School of Medicine, USA) conducted a Comparative Study of Lactose Assimilation Ability in Whites and Blacks in the United States. It turned out, unexpectedly, that among whites the number of people unable to assimilate lactose did not exceed 15%, and among blacks about 70%. This work has caused a number of studies in different countries. It was found that the ability to assimilate milk sugar in adults is not the norm for humanity, but almost an exception. This ability is possessed mainly by the white race. Those 15% of the whites in the United States who DO NOT absorb lactose, as it turned out, have in their a family of non-white ancestors. It turned out that Jews living in Israel and the United States, Arabs, Japanese, Chinese, Eskimos, South American Indians, many Representatives of the peoples of Africa, etc. are not able to assimilate MILK, while inhabitants from Northern and Eastern Europe have almost 100% assimilation of milk
Scientists have also set themselves the task of establishing whether it is possible to develop an addiction to milk by constant training? It turned out to be practically impossible to do. On the other hand, there were small "islands" of milk consumption in Africa. Fulani Nigerian people are 70% capable of assimilating lactose, while their neighbors cannot. Therefore, Fulani themselves drink fresh milk, and only "nono" is exported to the market - a local yoghurt variety, which practically does not contain milk sugar. (By the way, yogurt and kefir do not contain lactose, so these products can be taken by all nations).
Scientists have come to the conclusion that the ability of white people to assimilate lactose is explained by the fact that their ancestors were engaged in cattle breeding for a long time, while for all other peoples who have learned cattle breeding only recently by historical standards, typical lactose "indigestibility". The longer people are familiar with cattle breeding, the greater the process. The pattern is especially clearly manifested among the peoples of Africa, where it is easier to trace the ethnic purity of people. It was found, for example, in Uganda, the environment of the pastoral tribe of Toussaint, 80% of adults assimilate lactose, and the environment of the Ganda farmers - only 20%. Similarly, in Nigeria, the Fulani pastoralists differ sharply from their neighbors, the farmers for, Yoruba and Hausa. Scientists believe that the ability to assimilate lactose arose as a result of mutations, which became entrenched in pastoralists during evolutionbeing a useful feature. And for people who were not engaged in animal husbandry, this ability was not of particular importance and therefore disappeared.
Assimilation of milk is, in addition to DNA analysis, perhaps the main indicator of the purity of European blood. Why? Then, that he goes to the very essence of the Indo-Europeans, to their history as the world's first pastoralist people.

You can write in your passport that you are Russian or German, you can look like a Caucasian on your face, but you will NOT deceive the body. 100% assimilation of milk today ONLY among pure Slavs, Germans, Balts, descendants of the Celts. And no other people in the world. So among the Slavs, Germans, Balts and Celts, milk is even called almost the same (for example: English milk, German Milch). This is our ancient common Indo-European word from the time when we were not one common people (3-2 millennia BC). The same word is plow - in English plow.
According to modern science, the prevalence of milk intolerance (lactase deficiency) among Russians is 14%, Belarusians - 15%, Ukrainians - 13% (less), Karelov - 20%, Vepsians - 20%, Estonians - 23%. The Germans have a lack of perception of lactose on average - 14.8%, the Danes - less than 3%, the French - about 40%, the Swiss - 15.6%, the northern Italians - more than 50%, the Austrians - 21%, Czechs and Slovaks - 12.5%.
Other ethnic groups have milk “intolerance”: Latinos (USA) - 53%; Balkan peoples (Europe) - 55%; residents of Crete - 56%; southern French (Europe) - 65%; Greek Cypriots (Europe) - 66%; Cypriots - 70%; Sicilians - 71%; Italians Neapolitans - 84%; Iranians (Iran) - 86%; Greeks - 86.6%; residents of the Middle East - 90%.
As for the Jews, they have one of the highest rates of milk intolerance: Jews (USA) - 68.8%; Ashkenazi Jews (Europe) - 70 - 80%; Jews (UK) - 80%.
Asians (Central Asia) - 80%; Aboriginal people (Australia) - 85%; Khanty (Siberia) - 86.9%.
