Do you remember how as a child you were forced to drink milk and were told that it is very useful? Probably, this situation occurred with every second child. Parents did this for a reason, because it was believed that milk is a very useful product, not only for children, but also for adults. However, according to recent studies, the use of milk is not as smooth as we would like. In this article, we will talk about the benefits and harms of milk for the human body, and learn a lot of interesting things on this topic.
Is it useful to drink milk for children, adults and the elderly? We analyze the composition of cow's milk
Infants and children
Babies need mother’s milk, as they have not yet fully developed the digestive system and immunity. And this product is well absorbed in their small body. This is due to lactase, an enzyme that breaks down milk sugar (lactose).
But it is only about the mother’s milk. Give cow or goat milk in a diluted form is not necessary, because there is a high probability of rickets (lack of vitamin D). With the use of animal milk, the baby gets several times more phosphorus and calcium than it needs. Calcium is easily excreted, but phosphorus is not. To do this, the kidneys use large amounts of vitamin D and calcium, which is why the baby has a deficit of these elements.
When the kidneys are so developed that they can easily remove excess phosphorus, they do not use the entire supply of vitamin D and calcium. Therefore, after one year of life, the milk of a cow or goat can be given to children not only, but also it is necessary.
But what happens to our body when it gradually Matures? The amount of lactase begins to decrease. In Chinese and Japanese, this occurs at an early age, which is why they develop complete lactose intolerance (the medical term is hypolactasia). Europeans lose this enzyme more slowly.
In older people, the components of the microflora in the intestine change. Lactase does not work well and lactose, respectively, is not digested, but goes to the large intestine, where it is digested. The result of this process is the following symptoms:
- Abdominal distention;
- Abdominal pains;
It is interesting to know: scientists believe that the use of milk as a raw material for making cheese, yogurt or yogurt makes it possible to use dairy products even for those who have lactose intolerance, since the bacteria used to create fermented milk products contribute to the breakdown of lactose.
If you do not suffer from hypolactasia, you can safely drink milk, because it is a source of protein, calcium and many vitamins.
Nutritional value in one hundred grams:

- Phosphorus (11.3%);
- Cobalt (8%);
- Molybdenum (7%);
- Iodine (6%);
- Potassium (5.8%).
And in smaller quantities, magnesium, sodium, chlorine, chromium, selenium, and zinc.

How is cow's milk useful for human health
The beneficial properties of milk convince many not to give up this product. Here are just some of its positive aspects:

The benefits of milk for women suffering from mastopathy are also visible. It is made into a decoction with the addition of dill seeds. By drinking 0.4 liters of this product daily for a maximum of 14 days, you can get rid of seals and constant pain.
If we talk about the benefits of milk for men, we immediately remember athletes who need a large amount of protein. During training, they lose a lot of energy, so they constantly drink protein drinks. They can be periodically replaced with milk, which is rich in protein.
Some urologists recommend taking milk to increase potency. The components contained in the composition have a positive effect on the reproductive system of male representatives.
And how is milk useful for children? Its rich composition speaks for itself. Starting from one year old and older, if your child wants milk and does not feel uncomfortable after drinking it, then give him no more than three glasses a day.
Important: boiling helps to kill any harmful bacteria, but beneficial components are preserved.
It is believed that immunoglobulins, which are formed in protein foods, help kill bacteria that cause viral and infectious diseases. To get more immunoglobulin, you need a fast-digested protein that just gives milk.
Remember, all the minerals and vitamins that are in milk are found in other products. Therefore, this drink is not something necessary for children. If your baby doesn’t like it, don’t force it.
Important: if your child has had a rotavirus infection, in no case do not pour him milk. The ban on the use of this product should continue for two weeks. The thing is that rotavirus suspends the production of lactase, which breaks down milk sugar.
Is milk useful at night?
It is believed that a glass of milk before going to bed helps to cope with insomnia. It contains amino acids such as tryptophan and phenylalanine, which have a sedative property. If you want to improve your sleep, one hour before going to bed, eat a spoonful of honey and wash it down with milk. You can add a small pinch of nutmeg to the drink for better action.
Harm of milk to the body and contraindications to its use
There are enough contraindications to the use of milk. Its harm was especially often discussed after a number of experiments were conducted at the Harvard research center, the results of which were disappointing. For this reason, this medical school has completely removed whole milk from the list of products that benefit.
So, here is what harm milk can bring to a person:
- One glass contains about 10% of the daily dose of cholesterol, which is forbidden for an adult. The milk contains solid beef fat, which is the worst. This excess fat can lead to the appearance of atherosclerotic plaques. If you want to drink milk, its fat content should be equal to 0%.
- Milk that is sold in stores is brought from businesses where cows produce it 300 days a year. In its natural habitat, the animal gives this product only 180 days per year. In production, cows are fed special feeds, resulting in a 30-fold increase in the content of the hormone estrone-sulfate in milk. This compound increases the likelihood of cancer.
- Milk is a real allergen. One in four people suffers from lactase deficiency.
- Constant use of this product may cause the development of type 1 diabetes.
So, they say a lot about milk, some people consider it useful and drink as much as they want, while others decide to completely abandon it, because of the recently appeared information about the harm. If you are inclined to periodically use this drink, it is better to buy a natural one and boil it. Or buy only those products that are Packed in a Tetrapak or glass bottle. In addition, it is believed that ultra-pasteurization is the most careful type of treatment, in which all harmful bacteria are killed, and minerals and vitamins remain.
The benefits and harms of milk for children and adults is an urgent question that no one can give a final answer to yet.
