There is an opinion that such a product necessary for children as milk is not useful and even harmful to adults. Milk is supposedly capable of not only provoking the indigestion of the stomach, but also lead to a number of serious, including oncological diseases. We decided to check whether it is really so dangerous to drink milk in adulthood.
Search in Google issues about 407 000 results at the request of "milk is harmful after 30 years", approximately 1.31 million - According to the phrase “milk is harmful after 40 years” and 1.56 million, if you type in the search bar "Milk is harmful after 50 years." It turns out that the harm of milk seems to increase with age. Milk is accused of raising risks of developing cardiovascular diseases and appearance Memory problems. Eat messagesthat milk promotes leaching of calcium from the body, provokes edema and obesity, increases the risk prostate cancer And bladder in men and cancer of the mammary glands And uterus In women. At the same time, the law "On the consumer basket" assumed (concept abolished In 2020) that an adult should consume 290 kg of dairy products and milk a year. And the Ministry of Health calls The “rational” total consumption of 50 kg per year of milk, kefir, yogurt with a fat content of 1.5–3.2% and 60 kg of the same products with a fat content of 0.5–1.5%.
In milk and dairy products Contained Calcium, vitamin B12 and protein necessary for our body for the work of the muscle and bone system. Also, the milk of the milk includes a carbohydrate lactose, for the digestion of which an enzyme of lactase should be produced in the body in the necessary amount. The ability to absorb lactose appeared In the human population, only 7500 - 10,000 years ago in those regions where cows were domesticated. To date, after taking away from the chest in 80% of people of African and Latin American origin and more than 90% of Asian people, the level of lactase significantly Reduced, that is, older children and adults in these ethnic groups are unable to digest a large amount of milk. At the same time, 80–85% of immigrants from the northwestern regions of Europe produce lactase throughout life, which makes milk consumption possible in adulthood.
For many years, scientists from different countries have been looking for patterns between milk consumption and dairy products and the development of any diseases. Immediately we note that they did not consider the question of whether it is worth drinking milk to adults with lactose intolerance, since in this case, milk consumption is guaranteed to be guaranteed will lead To problems with digestion.
Milk and risk of fractures
In 1997, scientists from Massachusetts They came To the conclusion that significant (two or more glasses per day), milk consumption does not protect women aged 34 to 59 years from the risk of fractures. In 2014, Swedish scientists even notedthat women who drink more than three glasses of milk in a day, the risk of fractures increases. However, researchers warn against too literally the perception of such results, since they were obtained by observation. Consequently, it cannot be ruled out that those who were originally exposed to greater risk of fractures drank a large amount of milk for their prevention. Moreover, in the first study, in addition to milk, they studied the effect of calcium additives to prevent fractures. Researchers also did not find a significant effect of such additives, that is, calcium, which received food, was not a guarantee of bone strength. In 2015, a group of scientists from New Zealand Analyzed 59 scientific publications on the connection of milk consumption and risk of fractures. They came to the conclusion that the mineral density of the bones two years after increasing calcium consumption increases slightly, but in the future it remains unchanged, which means that the consumption of milk or additives with calcium cannot sufficiently protect against fractures.
From the data available today, it follows that the use of milk in adulthood is unlikely to protect a person from fractures, but at the same time it is not capable of provoking them, "leaching from the bones of calcium." Researcher and nutritionist Gale Kryl from the Cleveland Clinic Supplies Bottom line: "There is no sufficiently convincing evidence to justify the restriction of milk consumption." The conclusions look in a similar way meta zerosorpublished in the journal “Clinical and Experimental Studies of Style”: “From a scientific point of view, there is no reason to remove the product rich in calcium and other important nutrients from the diet of large populations”.
Milk and cardiovascular disease
There are sufficiently studies with regard to the consumption of dairy products, as well as milk and risk of cardiovascular diseases (SVD). Fats in milk, as in other products of animal origin, saturated, that is, they Raise The level of low density lipoproteins ("bad cholesterol"). Accumulating on the walls of blood vessels, these substances prevent blood flow and can cause a stroke. The most fully the question of how the consumption of milk and dairy products with the risk of SVD is connected, Meta analysispublished in 2017. Scientists analyzed 29 curtain studies with almost a million participants. They were talking about milk, fermented dairy products, cheese and yogurt. Researchers came to the conclusion that the use of these products does not increase the risk of coronary heart disease, as well as other SVDs. Moreover, the use of 10 g of cheese per day 2% reduces the risk of the SVD. Also, scientists did not reveal an increase in the risk of mortality from all causes when eating milk and dairy products.
The other is large meta It was published in the journal "Clinical Nuthersology" in 2019. Scientists came to the following conclusions: the consumption of all dairy products reduced the risk of mortality from all causes by 2%, and the consumption of cheese by 8%. Dairy products as a whole reduced the risk of mortality from Cerebrovascular diseases (strokes, blockages, stenosis and other brain arteries) by 4%, and milk - by 7%. At the same time, milk consumption increased the risk of death from coronary heart disease (coronary heart disease) by 4%, and fermented dairy products, such as yogurt, reduced this indicator by 3%. Scientists, however, made a reservation that it was premature to talk about the causal relationship between milk consumption and the risk of coronary illness, since it was not exclusively milk consumption, and milk, along with other dairy products. Instead they Recommended Choose milk with a lower percentage of fat content. Researchers from the Institute of Public Health and Clinical Nutrition of Finland Determinedthat only the consumption of a more liter of milk with a fat content of 3.5% per day is associated with an increased risk of coronary heart disease. Yurki Virtanen, one of the authors of the article, Supplies Bottom line: "Only milk consumption in very large quantities can be harmful, but there are no studies that suggest that moderate consumption is harmful."
Milk and oncological pathologies
Increased risk of malignant neoplasms from milk consumption Explain First of all, by the fact that during the period when the cow gives milk, it has increased estrogen levels. In 2005, one study tied The development of cancer of the mammary glands, ovaries and uterus with the ingress of large doses of estrogen from milk and dairy products in the body. However, later studies have refuted such a connection. Scientists Picked up 60 experimental mice (30 males and 30 females) with a different content of hormones for a little more than a week, and then examined their reproductive system. No changes in the animal organs occurred until the dose of hormones in milk was increased to one that would be 1000 times exceeding the norms of detention in ordinary milk. Similar experiments in humans, of course, are impossible due to their ineitability, but the author of the study Gregor Majich from the Center for the Genomics of Animals of the University of Ljubljan calls It is extremely unlikely that the sensitivity of people to estrogen is so more compared to mice. Laura Ernandes, engaged in breastfeeding biology at Visconsin University (USA), Agree With his colleague regarding the safety of hormones in milk: “In the end, human milk also contain hormones - we are mammals.”
Moreover, it is not completely impossible to use milk that is completely impossible. Stanford nutrition specialists Spent Experiment: people suffering from intolerance were offered to drink milk for eight days, consistently increasing the dose - from 118 ml to 710 ml. Symptoms of intolerance were not immediately manifested, but only with excess of the individual accumulation threshold. Thus, scientists Made The conclusion that even patients with milk intolerance can consume it in limited quantities.
Thus, for those who do not have lactose intolerance, scientists were not found in adulthood in adulthood. There are no studies that reliably demonstrate the growth of mortality from all causes or increasing the risk of developing cancer, depending on the volume of milk consumed. At the same time, the data suggests that milk and dairy products as a whole reduce the risk of cerebrovascular pathologies. However, it is still not worth abuse of milk, daily consumption of a more liter of fatty milk can increase the risk of coronary heart disease. In other words, to refuse a cappuccino in favor of Americano or completely eliminate the flakes with milk for breakfast only because you are no longer a child, definitely not necessary.
