Along with chalk, you eat dust, dirt, and various metal impurities. Only seasoned chalk can be used for food. special training to meet the requirements for food products and have Required documents. For example this one

Most of those who eat chalk consider it a neutral product that cannot cause harm. On this issue, scientists are divided in opinion and cannot answer unequivocally regarding the benefits or harm of eating chalk. They know only one thing - a craving for such a product can signal a malfunction of the body and that it is missing something. In such cases, it is advisable to determine why you want to eat chalk.

I want to eat chalk: what is missing in the body

It is generally accepted that if you really want chalk, then the body is sorely lacking iron or calcium. You definitely need to pay attention to this need of the body, especially if a person cannot resist such a “dish” or is ready to sit for hours and enjoy the smell of a freshly whitened room.

Often this condition is observed in pregnant women, because their body at this time requires much more useful vitamins and minerals. All those who use chalk for food (not only pregnant women) prefer lump chalk, because the natural product contains calcium, which is so necessary for the formation of tissues, bones, nerve cells, nails, hair, cartilage. It also has a positive effect on the functioning internal organs, condition of children's skin.

In this case, you need to pay special attention to your food, switch to balanced and proper food, try to buy only natural products.

The lack of calcium in the body must be compensated. Therefore, you should not ignore the desire to eat a piece of chalk combined with such symptoms as frequent fractures, caries, weak brittle hair, often peeling nail plate, muscle cramps, poor skin elasticity.

The craving for using chalk as food may also indicate endocrine disorders in organism. Diseases thyroid gland can provoke rapid removal of calcium from the body. In this case, just replenishing it is not enough; you need to be examined and cure the disease.

In very rare situations, those who like to eat food chalk have mental disorders. They just need to calm down and chew on something. Such people can eat more than 500 grams. product per day. We are not talking about any benefit here. If you can’t overcome this addiction on your own (get distracted by something or replace chalk with nuts, seeds, pieces of fruit), then it’s better to consult a psychologist.

Where do you get chalk for food?

In Russia alone there are about a hundred places where natural chalk is mined, but there are 3 special zones where the level of their production is the highest.

Volgograd region. The quarry stores about 25% of all chalk reserves throughout the country. The mineral mined here is considered one of the highest quality in the country. The amount of foreign impurities in chalk does not exceed 2%, which, if desired, allows it to be consumed as food. There are slight difficulties in obtaining it. They are associated with the high water content in chalk.
Belgorod region. About 23% of Russia's chalk reserves are located here. Good quality possible thanks to the 98% carbonate content in it.
The Saratov region has only 11% of chalk reserves in Russia.

Those who like to eat chalk should keep in mind that not all of it is equally healthy. You should use lump chalk with caution. It is not advisable to eat school chalk, as it may contain dyes, plaster and glue. The ban on consumption due to minor impurities also applies to goods purchased in construction stores or only mined in a quarry. It is also not advisable to try chalk that is fed to animals, since it rarely undergoes a cleaning procedure. The best option There will be food chalk for food.

Eating chalk and pregnancy

If you want chalk during pregnancy, this can be explained by the same lack of calcium and the increased need for vitamins and minerals during pregnancy. In addition, food preferences change noticeably during this period. According to the study, cravings for chalk occur in approximately 20% of all pregnant women.

Is it possible to eat chalk during pregnancy and will it be beneficial? Scientists say that this is more psychological relief and satisfaction of one’s “want” than saturating the body with minerals with the help of such food. To replenish the amount of necessary elements for pregnant women, it is better to pay attention to the right foods.

If you want to eat chalk, then 1-2 small pieces taken as food will not cause any harm to either the expectant mother or the fetus (provided that it contains no harmful substances).

Frequent use of chalk by children can dry out the epithelium of the larynx, digestive and respiratory organs; small cracks may appear, which will become an ideal environment for the proliferation of harmful microorganisms.

If a lack of calcium or iron is detected in a child or adult’s body, then constantly eating chalk will not save the situation. It is better to buy chalk for food at a pharmacy or pay attention to pharmaceutical drugs with these minerals or increase foods rich in them in your diet. In the latter case, it is worth paying attention to dairy products, buckwheat, pork or beef liver, prunes and pomegranates, bananas, apples, apricots, homemade black and red berries. There is no need to neglect dishes made from fish, seaweed, and vegetables. Nuts, dairy products, rosehip infusions, and citrus fruits will also be relevant.

Possible harm of chalk to the health of an adult

Many people, at the first sign of a lack of calcium or iron in the body, try to buy food chalk and make up for their deficiency naturally. But they do not take into account that such food (especially its overuse) may have a negative impact on the health of an adult:

Chalk can be deposited on the walls of blood vessels and in the kidneys, on the mucous membrane respiratory tract. The risk of kidney stones increases.
Once it enters the stomach, it can cause destruction of the epithelium and the formation of gases (especially if exposure to hydrochloric acid occurs).
High risk of increased blood clotting.
The risk of diseases of the endocrine system increases.
Muscle tone decreases.
Chalk as food can cause problems with stomach acidity.

Unpleasant consequences are mainly caused not by the chalk itself, but by its poor quality or too frequent use.

If you use chalk in food, it is better to buy a special product at the pharmacy. It is necessary to pay attention to its characteristics: the color is only white (there should not be any inclusions of another color). High-quality chalk should only be dry, clean and smooth. Its texture is delicate and fragile, but it should not crumble in your hands. Only by choosing such a product can you at least not extract maximum benefit from it, but not to harm the body.

Online stores can also become an analogue of pharmacies for buying chalk. But the selection of goods in them must be approached thoroughly, having previously studied the characteristics of the form’s reputation and reviews about it. This is important in order not to fall for the tricks of low-quality chalk manufacturers.

The phenomenon when a person wants to eat something unusual often occurs in Everyday life. It could be ice, clay, paper or something else equally exotic. But the undoubted leader in changing food habits is chalk. To verify this, just look at the forums. “I eat chalk!”, “I think about it all the time!” - these messages are very numerous, and they are not getting smaller over time. Therefore, it is worth understanding the reasons for this phenomenon and whether it is harmless to the human body.

Why do you want to eat chalk?

What happens in the body if it signals an imbalance in such an unusual way? Doctors, when asked why you want to eat chalk, answer that, first of all, this may indicate a decrease in hemoglobin levels. arises from various reasons: unbalanced diet, transferred surgical intervention, bleeding, taking certain medicines, chronic diseases. Therefore, if a person says, “I eat chalk,” the first thing he needs to do is take a blood test, which will help identify a lack of iron in the blood. According to statistics from the World Health Organization, about 2 billion people suffer from anemia. This disease develops when there is a difference between the iron used by the body and the iron supplied with food. Very often, when such a problem occurs, diet alone will not be enough. Specially designed ones come to the rescue iron supplements. Knowing this, a person with chalk should visit a doctor for diagnosis and treatment.

Iron deficiency anemia leads to the fact that the human body becomes defenseless against dangerous diseases. Therefore, one should not dismiss this, at first glance, harmless symptom like the desire to chew on a piece of chalk.

What you should pay attention to

If a person can say about himself “I eat chalk!”, he should be wary of other manifestations of iron deficiency anemia. These include pale skin, weakness, rapid heartbeat, decreased immunity, brittle nails and hair, shortness of breath, and unstable psycho-emotional background. Similar symptoms they say that iron deficiency anemia has already average degree heaviness, and without medical care not enough.

Familiar Stranger

In order to make sure whether you can eat chalk and how safe it is for the body, you need to understand what this substance is.

Chalk is a sedimentary rock organic origin, one of the many types of limestone. The basis of chalk is calcium carbonate (up to 98%), besides it, the composition of chalk includes: a large number of and metal oxides. Chalk is insoluble in water.

This mineral is widely used in agriculture, in the production of paper and metals, sugar, glass and chemical industry. He has mass useful properties, but, unfortunately, it will not affect iron deficiency in the blood in any way. Therefore, to the question of whether it is possible to eat chalk with anemia, the answer lies in the expediency of this action, because eating calcium carbonate in no way helps to eliminate iron deficiency.

Other disorders in the body

In addition to anemia, there are some other abnormalities in the human body that can lead to changes in taste preferences. Problems with the liver or thyroid gland cause calcium deficiency. If this organ does not function properly, a person may have a desire to eat chalk. This is explained by the fact that calcium in such conditions is excreted from the body faster than it is supplied with food.

Vitamin deficiency can also be the reason why you want to eat chalk. by the human body Calcium is absorbed only with a sufficient content of vitamins D, E and C. They regulate the absorption of this microelement, its level in the blood and the supply of the mineral to the bloodstream. bone tissue and teeth. Therefore even healthy people may experience an irresistible craving for eating chalk - this is how they compensate for the lack of calcium in the body.

During pregnancy

Well, who doesn’t know about the cute eccentricities of women during pregnancy. Perhaps the desire to chew on a piece of chalk is one of the most common. But is everything as harmless as it seems at first glance? If you want to eat chalk, what does this mean during pregnancy?

Research shows that even absolutely healthy women in an “interesting” position, symptoms of calcium deficiency appear in 17% of cases. This manifests itself as muscle pain, sensations of “crawling goosebumps”, muscle cramps. And in cases of complicated pregnancies concomitant diseases, this percentage reaches 50. Calcium deficiency can cause the development of such serious illnesses, such as osteoporosis and osteomalacia. Chronic deficiency of this microelement can lead to delayed fetal development. That's why future mom must receive the required amount of calcium, the norm of which is 1400-1500 mg per day.

How to avoid a deficiency of this important microelement? It should be noted that the largest amount of it is contained in calcium carbonate, and this is chalk. Nevertheless, it is worth informing your obstetrician-gynecologist about unusual taste preferences so that he can exclude iron deficiency anemia using laboratory tests.

What kind of chalk should you not eat?

In order not to harm the body, you need to eat only the “correct” calcium carbonate. But in order to find it, you will have to make some effort. This “product” is not sold either in a pharmacy or in a supermarket. Neither stationery chalk, which contains gypsum and glue for strength, will work, nor construction chalk - it also contains a lot of harmful additives. So what kind of chalk can you eat? If a person cannot do without such a “delicacy”, it is preferable to eat natural chalk, mined in quarries or extracted from rocks - it does not have harmful impurities. Being environmentally friendly natural product, it will replenish calcium deficiency in the body naturally. This chalk can be purchased in online stores.

Negative consequences

A small piece of chalk is unlikely to cause significant harm to the body. But a large amount of regularly eaten mineral can cause calcium to begin to be deposited in the kidneys and lungs. If taken uncontrolled for a long time, the mineral will accumulate in the pancreas, which can lead to the development diabetes mellitus and pancreatitis. Disturbances in the functioning of the cardiovascular system will not be long in coming after just a few months of drinking chalk in large quantities. Kidney stones can also form due to high content calcium. Therefore, before making a decision about whether chalk can be eaten, a person should also know about negative consequences consumption of this product.

Diet adjustments

Knowing why you want to eat chalk, you can adjust your diet in such a way that, if not reducing this desire to zero, then significantly weaken it. It is necessary to eat iron as well. These include: liver, veal, pomegranate, milk, cheeses, cottage cheese, sea fish, greenery.

Chalk is used in different areas– from industry to medicine. But for some people, this is food that they enjoy gnawing on. Some people start when they are still in school, while others are already at a conscious age.

“As a child, I picked at the whitewashed walls at home, then I carried chalk to school - it was the most delicious there. Not like now – pressed, with lime,” shared the Belgorod woman Ninel. – Now I buy chalk from my own store: I make seeds and all sorts of other things for the garden. This construction chalk is like powder. It happens that I eat three spoons of it every day. And I can’t explain why I want it. They say this happens when the body doesn’t have enough calcium.”

There are huge deposits of chalk in the Belgorod region - the names speak about this settlements: Belgorod, Belomestnoye, Melovoe. Kreida is even translated from Ukrainian as “chalk”. The soft white limestone is found mainly in the southeastern, southern and southwestern regions.

Belgorod chalk is widely ordered through online stores. For example, on Amazon 200g of limestone sells for $15. Anastasia from Belgorod and makes money from chalk, and eats it herself:

“When my husband and I come to the mountain, I look where the chalk is best. We cut off a suitable piece and immediately pack it, and when we arrive home, we process it: we bake it in the oven or dry it in the air.”

White business

Nastya started selling recently. First I read forums on the Internet, and then I decided.

She sells 100 g of chalk for 50 rubles, however, people take several kg at once. According to the girl, there are about 100 people in her client base.

“I have clients who have been eating chalk for 30 years, starting in school. I joined this hobby not so long ago: three years ago. Chalk contains calcium, which is very useful for our body, because it is the basis bone structure. In addition, chalk normalizes the iron content in the blood and has a very good effect on tooth enamel, preventing the occurrence of caries. It also helps people suffering from heartburn,” says Anastasia.

Russian-speaking chalk sellers don’t bother with names. Packages are named by origin: Sevryukovsky, Novooskolsky, Orenburg, Volokonovsky, Belgorod, Chernigov, Artyomovsky, Kramatorsk and others. According to connoisseurs, the taste of chalk depends on where it was mined. There are even videos on the Internet with recipes on how and what types of chalk are best mixed in a plate and how to bake chalk cakes.

“There is a soft, creamy chalk that immediately dissolves in the mouth, turning into mush, and has the smell of concrete and plaster,” Nastya explained. – There is hard chalk with the smell of rain, which is hard to bite off, and when chewed, turns into a grain. There is chalk interspersed with clay - for gourmets. That’s what it’s called – clay mill.”

Ours tastes better

On their forums, chalk eaters write that sawn chalk from Belgorod differs from Orenburg in structure, color and hardness: it is softer and melts in the mouth. And in general it is famous for being more popular among food lovers than any other.

On YouTube about 6 thousand videos where people of different ages They taste chalk from the Belgorod region on camera, covering their faces. This unusual delicacy is becoming more and more popular every day, not so much among Russians, but among Americans, Europeans and Asians.

By the way, melo-eaters are ashamed to talk about their addiction. Of the 30 respondents found on chalk forums, only two responded to us.

“I don’t understand why there should be a shame in eating chalk if this is what nature gives us. People began to eat chalk since ancient times, when there were no toothpastes, shampoos, or medicines. Our ancestors used chalk for these purposes and added it to food. This is why our grandparents are so strong and resilient,” says Anastasia.

On different websites where they sell chalk, they write almost the same thing: “ Only pure natural chalk, mined in quarries in the Belgorod region! Lump chalk is not subjected to any chemical treatments, unlike industrial and clerical!»

However, what is interesting: in Belgorod they do not produce edible chalk, at most for animal feed. There is no food GOST for it - in principle, it does not exist in Russia. And there is no certification for products on the Internet. Therefore, we can only guess what additives sellers use in their products.

Legitimate earnings?

From a legal point of view, such earnings cannot be called legal.

"Earth and others Natural resources are in private, state, municipal and other forms of ownership. Chalk is the same resource,” explained a representative of the Lawyer Karamazov company. Alexey Kolesnikov. – And here it is important to know who owns the chalk quarry. If it is private property, then such extraction of chalk will be theft: if more than 2 thousand rubles worth of chalk is collected, this is criminal liability under Art. 158 of the Criminal Code of the Russian Federation, if less - under Art. 7.27 Code of Administrative Offences.”

Most often, chalk quarries are used by the state, and it allows only individuals to extract chalk and other natural resources. This is regulated by Art. 11 of the Law of the Russian Federation “On Subsoil”. In particular, the law states that use is formalized by a license. And if you extract chalk without it, you will be held accountable. According to Art. 7.3 of the Code of Administrative Offenses of the Russian Federation for violating the rules for the use of subsoil, you can pay a fine of 3 thousand to 5 thousand rubles, for officials - from 800 thousand – up to 1 million.

In addition, citizens who sell goods and are neither individual entrepreneurs nor legal entities may be held liable for illegal activities and non-payment of income taxes.

Dangerous hobby

Head of the public health center and family prevention Lyudmila Kropanina warns that calcium abuse can lead to severe disorders, the formation of stones in the body and serious kidney problems:

“Calcium is absorbed only when it enters the body with additional supporting substances, and the calcium that we have in our quarries is not optimal for absorption. The risk of metabolic disorders will be 100%.
This topic with chalk did not appear just now - it has always been relevant. It’s just that earlier chalk lovers could not gather in one place due to the lack of the Internet. People who have a need to consume chalk should consult a doctor. They probably have something unbalanced: thyroid, high stress, overweight or other. The hype that is observed with meloeating is a lack of information and a lack of medical influence. These consumers need a different therapy – and it’s not chalk.”

Alena Antonova

The reasons for eating chalk are quite different, so we conducted a small survey among chalk eaters to find out who eats chalk and why.

In fact, chalk is not food product. When we call chalk food grade, we mean purified natural chalk without additives or chemicals, which is suitable for food, unlike stationery or precipitated industrial chalk.
Chalk is a rock of organic origin, based chemical composition The chalk contains calcium carbonate with a small amount of magnesium carbonate. Calcium carbonate is very poorly absorbed by the body, so it is practically impossible to get an excessive dose of calcium by consuming chalk. Chalk is a fairly inert substance, so you won't be able to harm yourself if you eat a small amount of it.

Is it possible to eat chalk? What does chalk taste like? Why do you want to eat chalk? How did you start eating chalk?
These are the questions we asked people who eat chalk:

Yazgul K.
I have been eating chalk since childhood, because my mother worked as a teacher and she ate chalk herself. At that time, you know, chalk in schools was not stationery :) There was lump chalk, natural, well, this very taste remained in my memory.
Then, when I grew up, I started eating calcium gluconate (tablets), because at school they found out that everyone ate this kind of chalk and replaced them with stationery chalk so that the chalk would not disappear from the boards. But all the same, by some miracle we found natural sawn chalk, and when it was not there, we ate calcium gluconate in batches. Believe me, at that time it also tasted better, not as bitter as it is now.
I think that I eat chalk because of anemia, i.e. low hemoglobin (I have suffered from this since childhood and constantly take medications). As soon as hemoglobin is normal, the desire to eat chalk disappears. But I can’t stop being drawn to the smell of chalk, dampness, wet asphalt, concrete, basement... That’s why I can smell chalk as much as I want!
I have been eating chalk for over 15 years (I’m 19 now).

Natalia T.
Before, I had never eaten chalk and didn’t want it and didn’t even know that they ate it. And one morning, in the fifth month of pregnancy, I woke up and realized that I terribly wanted chalk, namely lumps. I couldn’t find it for a long time and I don’t know why, but I started replacing it with lemons.
When I finally found chalk in our city market, I liked it from the first crunch. I started eating 1 kg per month, the amount increases every month, after 2.5 years I eat more than 5 kg.
I like chalk for its structure, density, crunch and even white color... When there is no chalk, it’s like a drug addict’s withdrawal symptoms. It seems to me that even the body is afraid, I want to sleep, in short - there is no life without chalk!

Darina M.
I never thought that I would eat chalk. The daughter-in-law broke her leg and really wanted to eat chalk after that. I tried it for company, so to speak. Liked. I still eat it :)

Ekaterina K.
Even at school I started carrying chalk (we had pieces of chalk and they were always of different densities). I collected a large bag and when I was doing my homework I constantly ate chalk and chose a tastier piece to crunch, I don’t know what it was connected with... And so on until grade 9 maybe.. Then I stopped, and when I was pregnant, I wanted it again, not just wanted it, but as the girl above writes, withdrawal symptoms began. I slept and saw the chalk in pieces like at school)))
Well, in the end I ordered natural 2 kg, ate for 3 days and gave birth. Now it’s lying there.. periodically I can gnaw off a small piece, but no more...

Marianna H.
I've been eating chalk since school. My classmates laughed at me. But I didn't care.
10 years later, I still haven’t stopped eating it. Relatives are surprised and do not understand how they can eat it. But anyone who does not crave the need for chalk will not understand what it is.
I like the fact that when I want chalk, my mouth starts to water. I have a mad desire to eat it: I feel like I’m about to eat not a piece, but a whole kilogram. This cannot be expressed in words, this desire. And when you take a piece and bite, you feel the crunch and understand that this is happiness for chalk-eaters. The chalk simply melts in your mouth. I want more and more. But this will only be understood by those who are chalk.

We now know that:
Most meloeaters are girls. Many of them started eating chalk as children.
Also, the desire to eat chalk often occurs in pregnant women.
None of the respondents could name specific reasons. For one hundred percent of respondents, the desire to eat chalk came from within, from the body itself.
Many doctors, especially of the old school, say that such a desire arises due to a lack of certain elements in the body, but as we already know, chalk gives practically nothing to the human body and is completely eliminated from it naturally. No harm, and no particular benefit.
