The benefits and harms of milk

Table of contents:

The benefits and harms of milk are interested in a large number of people who monitor their health. Conflicting data makes it difficult to establish whether there is a need of consumption of milk for adult person.

Harm of milk

We say a child that you need to drink more milk to grow healthy and strong man. Statistics, however, says other indicators. Modern doctors showed that in USA and in some European countries, where milk consumption is higher than normal, the hip fracture is diagnosed more often, which is a major feature of osteoporosis. In most cases, osteoporosis develops in women during menopause. Earlier it was believed that the disease is caused by a lack of calcium in the body.

But today it is proved that milk destroys bones, despite the fact that it is rich in calcium. According to the statistics, the consumption of animal protein becomes a cause of fractures. Unlike vegetable, animal protein is very acidic to the human body. This means that the tissues and blood become high acidity, which is totally not like the human body and it begins to resist.

To neutralize the acid, our body uses its own calcium from the bones. Such huge losses of calcium increases the risk of cracks and fractures, weakening the bones. That animal protein has a negative impact on the performance of calcium in the body, doctors began in the early twentieth century. Already at that time it was known about a significant increase of acidity, the content of calcium in urine also increases. Such patterns of consumption of dairy products is carefully studied since the late seventies of the last century.

If you double the daily intake of animal protein to 2 times, the increase in output of calcium in the urine reaches more than 50%. The famous Atkins center sponsored a six-month study, where in the course of work it was proved that all the people who are on protein diet, after six months allocated with urine much more calcium. The results of the early research is impressive, the relationship between statistics of fractures and milk consumption is obvious.

In 2000 he published the results of research conducted at the University of California San Francisco in the Department of medicine. Was used exactly 27 statistical questionnaires, drawn from 34 countries. The main criterionis a certain ratio of bone problems with the vegetable and animal proteins. With the prevalence of gluten in menu, the person can be traced to the absence of various fractures. These studies look pretty convincing.

The reports of these unique studies have been published in renowned research journals, showing how significant the linkage of animal protein with bone fragility of a person. Recently, a group of modern researchers of the University of California has published a new work. In the focus of attention hit 1000 women over 65 years. In this case, comparing the required data from many countries-participants, considering only the ratio of consumed plant and animal protein.

Observations were conducted for about 7 years. It was revealed that women consuming more animal protein, bone fractures were diagnosed about 3.7 times more than those whose diet contained a large amount of vegetable protein. The manifestations of bone loss is detected 4 times more often in those who drank milk compared to Amateurs of vegetable protein.

The results of this experiment provide clear mapping of progression of osteoporosis and fractures statistics of all studied women. To pass the figure of 3.7 times is incredibly important from the point of view of the necessity of drinking milk.

However, there is evidence that there is no risk of developing problems with the bones in the use of small quantities of animal protein, for example, not more than 10%. Also, studies were carried out in sparsely populated rural areas of China. There the ratio of animal protein to vegetable does not exceed the 10%. The rate of bone fractures is 5 times lower compared to the studied group of women in the United States. In Nigeria, this percentage ratio is even lower, and the statistics on the frequent fractures of the femoral neck was reduced by 99%.

These observations suggest that each reasonable person to question the harm of milk to the body of an adult. It is exactly proved that the various dairy products do not protect our bones, and incrementally destroy them.

The benefits of milk

But is the milk absolutely has no benefit for people? To begin to understand the composition of this product. Milk can be called the emulsion, from a biochemical point of view. It consists of incredibly small droplets of fat, whey and casein. The fat phase of milk is rich in vitamins A, D, and dissolved vitamins E and K. it Should be mentioned that the skim milk they are present in much smaller quantities. An unusual blue-green color wheyadds dissolved vitamin B12.

On milk sugar - lactose accounts for about 5-6% of the total weight of milk. With the disintegration of lactose in the gastrointestinal tract formed by galactose and glucose. This should be considered for all diabetics.

It is known that a single glass of milk can cover about a third of the daily requirement of the average adult human for vitamin B2, as well as half of the rate and vitamin B12. In addition covered a quarter of the daily requirement for calcium binding and vitamin D. milk Also contains a lot of magnesium, potassium and selenium.

Milk is not only rich in minerals and vitamins. Conjugated linolenic acid CLA is a biologically active agent contained in whole milk, enhances immunity, prevents the development of atherosclerosis, reduces the risk of obesity and developing certain types of cancer. Diabetes type II does not give the other component is an important TRANS – palmitinovaja acid. According to some researches regular consumption of whole fat milk speeds up the growth of muscles.

Long since in the East the milk was the best way to quickly calm the nervous system. In those days, doctors recommended to drink milk in the morning to get rid of sleepiness and activate the brain. Indian Vedas believed, this drink is required to use that people became more intelligent and gained a right vision of good and evil.

Moreover, milk is very beneficial to the gastric mucosa. It is considered a very effective remedy for painful heartburn, and reduces the acidity in the stomach. Also a great use of whole milk in the treatment of cardiovascular diseases, because it consists of potassium.

It perfectly strengthens the heart function, and most importantly, prevents strokes and heart attacks, reducing the risk by 37%. It is the potassium maintains the elasticity of blood vessels, lowers blood pressure. Small quantities of milk are recommended daily to drink a high blood pressure.

It is no coincidence that milk is attributed the property of weight loss of the human body. In Canada, studies were conducted for 15 weeks. A group of persons who drink a glass of milk a day reduced their weight by an average of 4 kg more than those who sat on the same diet and not drinking milk. The authors of the experiment believe that when it detects a lack of calcium in the brain increases craving for dairy products, which is a rapid weight loss.

Phosphorus, found in this drink are extremely important for normal functioning of the nervous system. It should be noted that phosphorus and other trace elements is retained during sterilization and the pasteurization of milk, the quality and tasteproduct do not change. Do not forget that in reconstituted milk powder, minerals and vitamins in their natural form are virtually absent. It should also be remembered that the fat content more than 3.6% reduces the benefits of milk, causing the increase of cholesterol in the blood.

Intolerance of milk (lactose)

People with lactose intolerance human milk can cause irreparable harm. Under such conditions milk provokes bloating, cramping, flatulence, vomiting and even diarrhea. With a lack of the enzyme lactase to digest this product the human body can not. Also not recommended to consume milk and those people who have problems with the intestines and stomach.

The main reason for this threat of lactose intolerance is considered a certain deficiency of the enzyme lactase. This enzyme must be produced in the small intestine in humans. By eating modest quantities of different dairy products main symptoms of this failure can hardly occur or be very moderate.

Instead of giving up the daily consumption of milk, for starters, experts recommend to make the analysis and to determine the level of lactose in the body of the patient. Such analyses will help to select the suitable dairy products. You can use lactose-free dairy products, nutritional value is not inferior to whole milk.

Since lactose is the carbohydrate of milk, it is considered a disaccharide according to its chemical structure. Lactose helps calcium and other minerals to be absorbed in the human intestine. In addition, lactose is used in food production to improve taste of many foods. As excipients lactose uses and modern pharmaceutical industry.

The enzyme lactase breaks down lactose easy on simple sugar that is necessary for its assimilation. This direct lactase deficiency may be primary and secondary.

Most newborn babies lactase is always produced in sufficient quantity. With age in some people, this enzyme may disappear partially or completely. Statistics show that this happens in 70% of the total population. This process is called primary.

Hypolactasia caused by lack of enzymelactase. The symptoms of this condition represent the abdominal pain and bloating is inevitable. Typically, these symptoms often occur when the activity of lactase was reduced to 50% of the typical level that is considered normal for infants. Many adults about 10% of the activity of lactase is enough to fully digest the lactose, so as not to cause unpleasant intolerance symptoms.

Congenital lactose intolerance is a very rare form of complete lack of the enzyme lactase. In this case, the enzyme is completely not formed in the human body. Newborns that leads to severe diarrhea, even from the mother's breast milk.

Secondary lactose deficiency is caused by external factors that negatively impact directly on the villi, damaging them. Cells that produce lactose, instantly destroyed.

Often these abnormalities provoke inflammation of the small intestine and serious intestinal cancer. When such a influencing factor in the villi of the intestine disappears, they self-recover, the ability of epithelial cells to produce the important enzyme lactase as normal.

The inevitable symptoms of lactose intolerance is always caused by certain conditions of lack of the enzyme lactase, when all the lactose or its prevailing part in the digestive tract do the splits. Under the influence of osmosis unsplit lactose attracts water, which causes the increase of water content in the intestine. The volume of the intestinal content also increases. Observed increased peristalsis, digestion in the intestine is faster than normal.

Further increasing of the velocity of the existing content of the intestine in humans the absorption and breakdown of lactose are always attenuated. The colon receives water and newswoman lactose. That is the inevitable result of the fermentation process in the colon formation of gases and acids, fatty acids with a typically short carbon chain. The acidity in the colon increases due to acetic and lactic acid. Diagnosed liquefaction of feces, what causes unpleasant diarrhea.

Bloating due to generated gases such as methane, carbon dioxide and hydrogen. The intestine is substantially stretched and the person feels pain. It should be noted that in addition to the main symptoms the patient may complain of other individual symptoms of intolerance to milk. It should be mentioned that even in one particular person the symptoms may vary, depending on diet, psychological and physiological factors.

In extremely rare cases fullthe exclusion of lactose from the daily diet are sometimes not conducive to a significant reduction of major symptoms. In their background they are such reasons as a set of minor symptoms associated with irritation of the intestinal wall.
