Why is there a need for chalk?

Most products do not contain necessary for the body the amount of minerals and vitamins, their lack causes various health problems. Many products that should contain calcium are unnatural, which means they have 0 benefits. Without getting calcium, you have a desire to chew on a piece of chalk, thus receiving a large amount of calcium.

If you have convulsions (even with hypothermia), blood begins to clot worse, hair loses its shine and falls out, bones and nails become brittle, it means there is not enough calcium.

In addition to slagging the cells, it has a detrimental effect on the condition of delicate gums and fragile baby teeth: solid particles scratch the mucous membranes and enamel, leading to the development of caries, stomatitis, and other oral diseases.

Chalk dries out the epithelium of the larynx, respiratory and digestive organs, promotes the formation of microcracks where favorable conditions for habitation and reproduction of pathogenic microorganisms. Therefore, to the question: “Is it harmful to eat chalk,” there is only one answer - it is very harmful, especially for children.

Dangerous consequences

Many people, exhausted by diseases associated with calcium deficiency or anemia, ask: where can I buy chalk for food?

If you are very lucky and have the opportunity to buy pure chalk, the benefits of its use are small: calcium is absorbed quickly and effectively only from natural products that contain all the mineral elements and vitamins in combination. When eating chalk, there is a danger of sedimentation and concentration on the mucous membrane of blood vessels, deposits in the kidneys, liver, and respiratory tract. And when it gets inside the stomach, with the assistance of hydrochloric acid, chalk causes a violent gas formation reaction that destroys the epithelium.

It is difficult to unequivocally answer the question of whether they eat chalk. Of course, it does not apply to food, but in some cases it may be useful. Consider all the arguments for and against taking it, find out when and how it can be done.

It is a sedimentary rock white, formed from the fossilized remains of algae and animals that lived here thousands of years ago. It contains calcium with inclusions of magnesium, metal oxides, and quartz grains.

A person needs calcium from birth, and chalk itself could serve as one of its sources. But various additives may be undesirable and even harmful to nutrition. There are several types of this substance, externally similar, but differing in chemical composition:

• Building. It contains chemical additives necessary for the work that are harmful to health.
• Clerical. For strength, gypsum is added, and pigments are added for color. It is not dangerous, but is not intended for food.
• Stern. It is used to feed animals and is not suitable for humans.
• Food. This product is as free from impurities as possible and can be used for food.
• Children's crayons. During their production, it is taken into account that the child puts everything into his mouth and can bite off a piece, so the amount of additives is minimized.

It should be taken into account that the calcium contained in crayons is poorly absorbed by the body. Therefore, even having chosen a species that is safe for the body, it is worth thinking about the advisability of eating it.

The desire to chew on a crayon doesn’t just happen. If the body lacks calcium, it looks for ways to solve this problem, causing the need to make up for this deficiency in any way. This need may arise in pregnant women and young children and is eliminated by taking a vitamin complex.

Once in the stomach, calcium changes its properties. Under the influence of gastric juice, it oxidizes and ceases to be chemically neutral. As a result, it irritates the mucous membrane without providing therapeutic effect. Calcium is not retained in the body, so dieting becomes pointless. It does not help with heartburn, but it causes constipation and metabolic disorders.

The appearance of an irresistible desire to chew crayons can be a symptom of a dangerous disease. It is advisable to undergo examination and make sure that it is not caused by iron deficiency anemia. In this case, a course of treatment will be required.

Pure chalk, free of impurities, is harmless in small quantities, but does not bring any benefit. Better adjust your diet, eat more calcium-rich foods, buy calcium gluconate at the pharmacy.

It often happens that the body demands to eat something unusual. And in Everyday life– this is a common phenomenon. Some people like to chew on ice, others like paper, and others enjoy the act of eating clay. But chalk occupies a leading position among food preferences.

This statement is not unfounded. It's easy to verify. All you have to do is go to the forums, where they are full of messages: “I eat chalk!”, “I want to chew a piece of chalk,” “I eat chalk every day, and I can’t refuse.” Such messages are numerous, along with this, people understand that eating chalk is not the norm, which is why they ask questions - why do they eat chalk and is it so healthy? Or maybe, on the contrary, eating chalk is harmful?

In reality, the benefits and harms of the product are ambiguous. In small quantities, natural chalk has no effect negative influence to your health. According to doctors, such a taste preference is nothing more than a signal from the body that there are not enough mineral components.

Let's figure out why chalk is harmful to the body? Why can't people give up this habit, and what negative consequences can there be?

Why do you want to eat chalk?

The habit of eating stationery chalk is a perverted nutritional requirement body. In the majority clinical pictures the reason lies in calcium or iron deficiency in the human body.

When a person experiences an irresistible desire to eat a piece of chalk, but cannot control himself or is ready to enjoy the smell of fresh whitewash for hours - this is not normal, the body is signaling a failure. It means that the body needs mineral components.

Despite the fact that it is now popular healthy image life and proper nutrition, a person’s diet can hardly be called complete. Some people strictly limit their food intake, while others, although they try to buy farm-made food that is “supposedly natural,” still do not get the required amount of vitamins and minerals.

The point is that in modern world It’s really difficult to find natural products that do not contain harmful components, while being rich in substances necessary for normal functioning all organs and systems. And we are talking about real cheese, milk, cottage cheese and other products that are the main source of calcium for humans.

When there is a deficiency in the body mineral element, the body gives a signal that makes you crave chalk. The chalk product consists of 98-99% calcium carbonate, which is why there is an abnormal need to eat it.

The second reason for dietary habits is iron deficiency anemia. In other words, the body is acutely lacking iron. If you eat enough dairy products, pathological cravings can be leveled out. If milk and cheese do not help, it is recommended to donate blood to determine the concentration of hemoglobin. It is possible that the analysis may show low iron content and hemoglobin levels.

Iron deficiency anemia weakens the body, making it defenseless against many diseases. Therefore, one should not ignore such a symptom as the desire to chew a piece of chalk.

The benefits and harms of chalk for the body

People who consume chalk need to visit the dentist regularly, since calcium deficiency in the body leads to brittle enamel. When eating solid food, microcracks appear on it, in which pathogenic microorganisms can settle, leading to the development of caries.

Is it good to eat chalk? It is believed that in this way calcium enters the body, which is beneficial for teeth, bones, etc. But in reality, a strange eating habit does not bring any benefit. Why is that?

Calcium, which is contained in chalk, is not absorbed in the human body, and therefore there is no benefit. At best, its effect is neutral, at worst, serious health problems can develop. But the second option is not excluded only in cases where a person consumes literally kilograms of chalk.

Medical experts comment on eating habits:

• There is an opinion that eating chalk leads to the formation of kidney stones. This is an ambiguous statement. This really happens if a person eats kilograms of it every day and for long period time. Then not only the kidneys suffer, but also blood vessels/ arteries, gastrointestinal tract, lungs and other internal organs, as they are covered with a layer of chalky plaque. But 2-3 pieces a day will not do any harm. But provided that the chalk is clean;
• Is it harmful to eat chalk? It depends on what it is, doctors say. Stationery chalk contains additional substances, in particular, it contains gypsum, glue, and sometimes dyes. This is definitely not good for the body. Unrefined chalk or whitewash may contain harmful substances of various natures, which will affect health and well-being.

Truly pure calcium can only be purchased in pharmacies - it is calcium gluconate. It is sold in tablet form. Of course, its taste is somewhat different when compared with ordinary crayons, but you can be sure of safety, since the drug goes through several stages of purification from various impurities.

Negative effects of drinking chalk

Chalk is a sedimentary rock of organic nature and is one of the many types of lime. The basis is calcium carbonate, containing a small concentration of magnesium and metal oxides. Does not dissolve in water. If the reason for the desire to chew lime is calcium deficiency, then to some extent it can be absorbed, provided that there is a sufficient amount of vitamin D in the body, ascorbic acid and tocopherol. The mineral component itself is not absorbed.

When the cause of pathological desire lies in iron deficiency anemia, then drug treatment aimed at replenishing iron deficiency is required. Consumption of chalk has no effect on iron concentration, and anemia leads to various problems with health - constant weakness, pale skin, hair loss, etc.

If you eat a lot of organic minerals, the functionality of the kidneys and lungs may be impaired. Uncontrolled consumption over a long period of time increases the risk of developing diabetes mellitus or pancreatitis, since lime can settle on the pancreas. Cardiovascular disorders will not be long in coming.

These complications are a consequence of excessive consumption. If the “dosage” is several pieces per day, then it’s okay. If you really want to, then, of course, you can, medical experts say.

It wouldn’t hurt to get tested for content minerals– timely response to body signals can protect you from many problems in the future.

Eating chalk during pregnancy

Perhaps everyone is familiar with the eccentricities of pregnant women who interesting position ready to experiment with your diet. This is explained by the fact that during pregnancy there is an increased need for vitamins and minerals. But how harmless is such a habit?

Research shows that even absolutely healthy woman Without pregnancy pathologies, you may have a desire to eat chalk. Such pathological cravings are detected in 17% of cases. Most often, the desire is caused by a lack of calcium in the body. If the pregnancy is complicated chronic diseases, then every second woman changes taste preferences.

Is it possible to eat chalk during pregnancy? Doctors still recommend consuming calcium gluconate, since this drug is safe and has no contraindications. However, if you really want chalk, then you shouldn’t deny your body.

There will be no harm from a few pieces, provided that there are no harmful substances in its composition. But no benefits are identified, with the exception of psychological satisfaction.

Why do you want to eat chalk? The desire to taste something unusual is probably familiar to every person. Chalk tops the list of strange food addictions. It is often chewed on by schoolchildren and pregnant women. Experts are convinced that a bad habit can be an indicator dangerous diseases or conditions and have a detrimental effect on health. Are there safe ways satisfy the body's needs? Read.

What is chalk?

To answer the question of why you want to eat chalk, you need to figure out what the named substance actually is. So what is chalk?

Chalk is a natural material of organic origin, one of the many types of limestone. This substance is formed from ancient sediments - skeletal fragments of animals, shells of prehistoric mollusks, calcareous growths of algae. Cretaceous rock consists of two parts: carbonate and non-carbonate. 98–99% of the carbonate part is represented by calcium carbonate. The non-carbonate part is formed by metal oxides, quartz sand, clay, marls and other compounds.

In Soviet times, they wrote on school boards with this kind of chalk. It was called lumpy. Later, especially for educational purposes, they began to produce pressed chalk, the basis of which was gypsum mixed with limestone, starch, glue, and dyes.

Thus, chalk is mostly a calcium carbonate salt.

Why do you want to eat chalk?

Experts are convinced that unusual gastronomic preferences are a signal from the body that there are not enough substances for its normal functioning. The mechanism of natural self-regulation is triggered. You need to listen to such calls very carefully so as not to trace the onset of the disease.

Why do you want to eat chalk? First of all, this may indicate that a person has decreased level of hemoglobin in the blood. It has been noted that with iron deficiency anemia, the functioning of taste and olfactory receptors occurs. Patients complain that they have an irresistible desire to eat chalk, clay, sand, paper, sniff kerosene, paints, and wet tobacco ash. If there is weakness, decreased immunity, cardiopalmus, tearfulness, brittle nails, pale skin, then you must immediately visit a doctor and get tested for your hemoglobin level.

One more probable cause a strange desire to eat chalk can become calcium deficiency in the body. Experts say liver dysfunction is the culprit for poor absorption of the mineral in the body. thyroid gland, as well as a lack of vitamins D, E and C. This means that if a wild craving arises to chew chalk, it is necessary to check the condition of these organs and increase the consumption of vitamins, preferably natural ones, since their absorption is 90% (synthetic ones are absorbed only by 10 %).

Having determined why you want to eat chalk, let’s figure out whether limestone will help replenish calcium reserves in the body and whether it’s dangerous to chew on it.

Will chalk make up for calcium deficiency? Limestone damage

Is chalk capable of replenishing the lack of calcium in the body? To answer this question, let us turn to human physiology.

It has been proven that calcium carbonate, which is the main component of chalk, contains 40% elemental calcium. This is much more than in other mineral salts (citrate, gluconate, lactate and others). However, the absorption of this form of calcium is quite low - only 17–22%. And this is subject to normal or increased acidity of gastric juice. If the acidity is reduced - and such cases in medical practice quite a lot - the degree of absorption of the macronutrient is practically equal to zero. So eating chalk will not bring any benefit to the body, but it will add a lot of health problems.

One such problem is the formation of kidney stones. Calcium carbonate settles in the main organ of the excretory system and causes the formation of sand and the hardest kidney stones that are difficult to dissolve - calcium oxalate.

In addition, the body spends a significant part of the body on the absorption of large amounts of chalk. of hydrochloric acid stomach, which protects the body from the penetration of harmful microorganisms with food. As a result barrier function gastrointestinal tract weakens. People often suffer from infectious diseases.

Eating chalk poses another serious danger - lead contamination of the body. American scientists studied calcium compounds natural origin and found in them high doses heavy metal(6–25 mcg per 800 mg calcium). Getting rid of lead, once it has entered the human body, will be very difficult in the future. The metal affects the brain, kidneys, and red blood cells. Lead is especially dangerous for children. Metal poisoning causes a decrease in their intellectual abilities (and therefore academic performance), and a change in behavior (unmotivated aggression is observed).

What to replace chalk with?

If the answer to the question of why you want to eat chalk is a banal lack of calcium, it is necessary to establish the cause of poor absorption of the macronutrient, eliminate it, and only then replenish mineral reserves, having first decided what to replace the chalk with.

There are many natural remedies that can effectively and gently improve liver function. For example, elecampane is tall. The root of the plant increases bile formation, enhances bile excretion, cleanses the liver and bile ducts of toxins and waste.

Safely recover hormonal balance White cinquefoil will help with thyroid diseases. The use of plant rhizomes has been proven to be highly effective for both hypothyroidism and hyperthyroidism.

For ease of use, both plants are available in tablet forms - preparations Mesi-Vit And Tireo-Vit. The entire variety of beneficial substances inherent in herbs by nature is preserved in the named biocomplexes thanks to the use of a unique cryoprocessing technology.

Bioavailable natural vitamin complexes, For example Apitonus P.

After restoring the impaired functions of the liver and thyroid gland, you can begin to eliminate calcium deficiency. Preference should be given to easily digestible and safe forms of calcium and preparations based on them, such as Osteomed, in which the mineral is presented in its citrate form.

If an attempt to find out why one wants to eat chalk brought a person to a hematologist’s office, then the reason for the strange food addiction is a low level of hemoglobin. In this case, nature will again come to the rescue. There are many plants that can effectively replenish iron deficiency in the body. One of them grows literally under our feet - stinging nettle (contained in the preparation Nettle P). Biologically active iron atoms contained in hot herb can easily integrate into the formula of human hemoglobin (they are heminic) and quickly increase its level.

Eliminating pathologies that prompt the body to demand chalk for itself will save a person from many health problems, so neglect strange symptom not worth it.

Is it possible to eat chalk, or is it a bad habit? First of all, this is a symptom of a lack of certain microelements, which in itself is not good.

“Are your crayons edible?” - sellers in stationery stores hear this question much more often than you might imagine. Buyers say this in a whisper, embarrassed by their strange taste preferences, as if expecting to be laughed at... In fact, there is nothing shameful here. “Malnutrition” is just a sign of a lack of calcium or iron in the body. If you are constantly tempted to chew chalk, this is a reason to think about your health.

Why do you want to eat chalk?

Let's figure out why you want to eat chalk. Which of the two microelements are you missing? The choice of treatment method depends on this.

It's no secret that all food products in modern stores are by no means highest quality. Therefore, almost every city dweller suffers from a lack of microelements and accompanying problems. On supermarket shelves it is almost impossible to find natural milk, cheeses, and fermented milk - and they are precisely the main source of calcium for humans. Not getting enough of it, you feel an irresistible urge to chew chalk: we all remember from school chemistry course that it consists almost entirely of calcium.

Symptoms of calcium deficiency - (including hypothermia), deterioration and appearance hair, nails and teeth, as well as less noticeable signs - bones become brittle, blood clots worse. If there is a slight deficiency of this microelement, it is enough to know which foods contain calcium and consume them more often: this is still dairy, but also fish, nuts, legumes, rose hips, citrus fruits, cereals, vegetables... If there is a severe deficiency, you can enhance the effect by taking special dietary supplements or calcium gluconate tablets.

Mel-eaters should also be examined regularly by a dentist - at least once every four months. When teeth lack calcium, their enamel becomes fragile and brittle. While chewing rough food, microcracks form on it, into which putrefactive microorganisms enter, causing the development of caries. With what formerly a doctor detects and cures caries, the less suffering will fall on the patient. And the cheaper the dentist’s services will cost him. But if your teeth are already seriously damaged as a result of calcium deficiency, get ready for significant expenses. In this case, it is especially important to find a good dental office with honest prices. Here is the website of the Eva-Dent clinic - they do their work conscientiously, but the cost of treatment is acceptable for people of any income level.

In addition, people suffering from iron deficiency (anemia) constantly want to eat chalk. They are given away by dry pale skin, fast fatiguability and drowsiness, in some cases early gray hair, rapid pulse, shortness of breath. In this case, you need not calcium-containing, but iron-containing products - this is primarily red meat (better), beef liver, hematogen. If you do not eat animal products, you should take dietary supplements or vitamin cocktails with. Eating chalk if you have iron deficiency is useless, and moreover, it can be harmful.

Is it harmful to eat chalk?

Many chalk eaters are interested in: is it harmful to eat chalk? In what quantities does it not pose a health hazard? I will answer these questions.

There is an opinion that chalk consumed as food provokes the formation of kidney stones. This is only true under one condition: if you consume it in unimaginably large quantities, literally in kilograms. Then not only the kidneys will suffer - the entire intestines, blood vessels and even the lungs will become covered with a layer of limescale. But two or three small pieces Clean chalk a day will not do any harm - however, it is worth emphasizing: just clean chalk.

Is it possible to eat school chalk sold in office supply stores? It’s better not to – it contains plaster, glue, and sometimes dyes, and all this will certainly not benefit your body. Unrefined chalk from a quarry or from a hardware store, as well as whitewash, may contain bad impurities of a very different nature. Calcium for animals is also not thoroughly purified. Truly high-quality, pure chalk can only be bought at a pharmacy, in the form of calcium gluconate tablets. It tastes a little different from regular chalk, but you can be sure of its safety. This drug costs a penny - unlike more expensive dietary supplements. Which sometimes are no better - except that they are packaged in prettier and brighter packaging.

We figured out whether eating chalk is harmful, but whether it is healthy is still an open question. The fact is that calcium is quite poorly absorbed by the human body, especially in its pure form. Eating crayons and whitewash, even in large quantities, does not fully solve the problem of micronutrient deficiency. Roughly speaking, it is more advisable to eat one hundred grams of cottage cheese than one hundred grams of chalk: in combination with other substances, in particular acids and vitamin C, calcium is absorbed better. Therefore, nutritionists advise drinking calcium-containing medications with citrus juices. And of course, optimize your nutrition.

Calcium for pregnant women is one of the most important microelements, since it forms the child’s skeleton. A woman can feel its deficiency throughout the entire nine months, and even after childbirth, so gynecologists advise taking special mineral and vitamin complexes from the first trimester. Whether they are so good is also a moot point: balanced nutrition pills still do not replace, but can only serve as an addition to it. Among adherents of naturalistic motherhood, there is an opinion that taking medications for pregnant women can cause a lack of lactation after childbirth. And if you take into account the fact that everything fewer women V last years practices breast-feeding, this statement no longer seems unequivocally absurd.

There is one folk recipe against calcium deficiency - eggshells ground in a coffee grinder to a powder form are added to food or taken dry, washed down with the juice of sour fruits (orange, lemon, cranberry...). Unlike pure chalk, it does not lead to the formation of limescale on the walls internal organs, and therefore eggshell as a source of calcium - a purer and harmless product.

We all know the basic truths about what you need to eat 3-4 hours before going to bed, about how useful calcium is for bone tissue, about the content of vitamins in a particular product. But this is not an example for everyone. Often, many of us, having unique food preferences, eat...chalk. Is it necessary to do this? Certainly not.

Essence of Chalk

At its core, chalk is neutral, but many doctors are categorically opposed to eating it. Some people consider it an indispensable source of calcium. Women in “interesting situations” have a special affinity for chalk. What causes this? The body of a pregnant woman is in dire need of calcium due to the need for the formation of bone tissue by the child growing in the womb. And children who have not reached school age, happily remove pieces of lime from whitewashed walls and eat them during the period of active growth.

How does chalk affect the body?

Calcium from chalk cannot be called useful; in such a concentration it has a negative effect on blood vessels. And its impact on digestive system person and completely aggressive. In the acidic environment of the stomach, it harms the mucous membranes of the gastrointestinal tract. Doctors recommend using special vitamin and mineral complexes if you need calcium; this is much better than eating chalk. Although many of those who eat it refer to the fact that it is added to pet food, which means it is safe, but this is not at all the case. The fact is that digestive tract and the stomachs of animals are evolutionarily oriented towards coarser and more aggressive food.

It is also worth remembering that special chalk that is adapted for human consumption does not exist in nature and cannot exist. And the material used in construction contains a great variety of chemicals and other harmful substances, which can be fraught with poisoning. School chalk is also completely unsafe; during its production, to make it hard so that it crumbles when writing on the blackboard, it is supplemented with gypsum compounds.

Another aspect that speaks of harmfulness may be the coloring of chalk, because chemical, not food, dyes are used to produce colored chalk. Only when making crayons for drawing is it taken into account that children at an unconscious age can bite off if they try it on their teeth, so natural, safe dyes are used for it.

Eating chalk as a harbinger of disease

Another reason to eat chalk may not be a lack of vitamins or macroelements and calcium, but such serious illnesses like anemia or anemia. In these cases, a person develops iron deficiency, hemoglobin drops, and a lack of oxygen occurs. He feels numbness in the limbs, a decrease in body temperature, malaise, dizziness, and apathy sets in.

All this happens exactly until the person defeats the disease. I want chalk, but it doesn’t cure, it only aggravates the body’s problems, a course is needed for treatment special drugs and procedures. You can help without medical influence and restore the internal reserves of the body with the help of pomegranate juice, raising hemoglobin; red grape wine; hematogen, which is now sold at any pharmacy kiosk.

Modern lifestyle has a huge impact on human health. More and more often you can find people suffering from vitamin deficiency and insufficient amounts of nutrients in the body. That is why in Lately Chalk for food is very popular.

I want chalk, what does that mean?

Many consider the need for chalk to be a very strange phenomenon, abnormal for the average human body.

In everyday life, the desire to chew chalk is usually associated with pregnant women; indeed, they often have such taste preferences. This is due to the fact that during the period of fetal formation and growth female body double portions of vitamins and microelements are required.

Particularly important is the adequate amount of calcium that lump chalk contains for meals. He serves building material for most fabrics, nerve cells, skeleton, cartilage tissue, hair, nails, internal organs and skin of a small person.

However, a lack of calcium can accompany absolutely any person; it is usually characterized by the following symptoms:

• Brittle and dull hair;
• Caries, bone fragility (frequent fractures);
• Brittle nails prone to splitting;
• Dull skin tone;
• Loss of skin elasticity;
• Muscle cramps;

Such states characterize pronounced violation calcium metabolism, which natural food chalk will help you cope with.

What is chalk made of?

The composition of chalk for food is represented by a combination of inorganic salts(carbonates). The main element of such compounds is considered to be Ca (calcium). Many are sure that natural lump chalk is nothing more than the carbonate CaCO3, known to everyone from school.

However, an in-depth study of this issue makes it possible to verify that chalk for food includes other elements of the periodic table:

• Of course, calcium oxide takes up almost half component composition substances. The CaO content in the mineral reaches 55%.
• The second position in the list of components is occupied by carbon dioxide or CO2. Its share in the composition of chalk sometimes reaches 43%.
• The oxide of a metal such as magnesium (MgO) occupies a very small volume, which usually does not exceed 2%.
• The quartz component affects the density of food chalk in direct proportion. The more SiO2 a substance contains, the higher its density. The mass fraction of quartz from the total volume sometimes reaches 6%.
• Al2O3 is quite slightly inferior in volumetric content to quartz inclusions. The total volume of aluminum oxide in limestone corresponds to 4%.

Sometimes you can find natural chalk with a pinkish or even reddish tint. The breed has this feature thanks to increased content iron oxides. In ordinary white chalk, the Fe2O3 content does not exceed the threshold of 0.5%.

Where is chalk mined?

Those wishing to compensate for calcium deficiency should know what food chalk is and where it comes from.

In the territory Russian Federation There are more than 100 deposits of natural chalk. Among them, three zones stand out in which the concentration of carbonate reserves reaches high levels.

The Volgograd region takes a huge share of this figure; its quarries account for up to 26% of the country's reserves. Lump chalk from these deposits is of excellent quality, it contains a minimal amount of impurities. The number of foreign inclusions does not exceed 2%. However, Volgograd chalk is quite saturated with water; the water content in dry chalk exceeds the specified standards by almost 10-15%. This fact makes it difficult to obtain.

The next position is occupied by the Belgorod region, where up to 24% of chalk reserves are concentrated. The delicious chalk mined here is 99% carbonate, which is an excellent indication of its high quality.

The Saratov region owns an 11% share in the total chalk wealth of the Russian Federation.

Harm and benefits of chalk when eaten

Lump chalk for food is becoming increasingly popular, harm and benefit of this substance are still discussed by experts today. It is not possible to unambiguously evaluate a sedimentary mineral, because it has both negative and positive influence on the human body.

The benefits of natural chalk for food are as follows::

1. Strengthens fragile bones and serves as a preventive measure against caries;
2. Helps maintain healthy and beautiful hair, nails, teeth and skin;
3. In small quantities it helps to improve the functioning of the digestive system;
4. Provides joint mobility and muscle elasticity;
5. Promotes proper operation of cardio-vascular system;
6. Participates in metabolic processes at the intercellular level;
7. Affects blood clotting and hemoglobin levels (indirectly).

Tasty chalk for food has a negative effect only when there is an excess of it in the body.

Excessive calcium intake leads to the following side effects:

1. Increased blood clotting;
2. Reduced strength of bone tissue and tooth enamel;
3. The emergence of a risk of diseases of the endocrine system;
4. Angina;
5. Decreased muscle tone;
6. The appearance of kidney stones;
7. Increased acidity of gastric juices, which contributes to the development of diseases of the gastrointestinal tract (gastritis and ulcers);
8. Gout;
9. Calcinosis (deposits of Ca salts in the tissues of internal organs).

Talking about negative consequences consumption of chalk for food, we can conclude that they are caused by the quantity and quality of the mineral consumed.

Which chalk is best for food?

People with a lack of calcium in the body are often interested in where to buy chalk for food and which one is best. They are also studying the question of what is the most delicious chalk for food.

When you want to chew on block chalk, blackboard chalk usually comes to mind. However, this product not only will not bring benefits, but can also cause harm due to the presence of chemical additives in it. Such substances poison the body, the resulting toxins disrupt the functioning of internal organs and spoil health in general.

It has been proven that school crayons dry out the airways by settling on the epithelium of the larynx. They also clog blood vessels, liming occurs, which leads to malfunctions cardiovascular systems.

The solid particles that this type of chalk contains can scratch the tooth enamel, which will inevitably lead to caries. They act similarly on the oral mucosa, creating microscopic wounds in it that are invisible to the human eye. These cracks are a direct path to the appearance inflammatory processes and the penetration of infection into the body.

Once in the stomach, school chalk causes a reaction similar to the extinguishing process. This chalk is less tasty compared to its natural counterpart.

Everyone has their own cockroaches in their heads.

Some people like to sniff gasoline.

Someone loves it salted fish with a scent.

Someone is intoxicated by the smell of paint or sniffs their little finger after picking it in their ear.

Don’t feed someone bread – let them chew resin.

Someone bites their nails or pencil lead.

For someone else, take out and put in a flabby carrot. This is me talking about myself. So sometimes there is a desire to gnaw on a carrot, and, moreover, a flabby one - I can’t save it. The same probably applies to people chewing chalk. Well, they want to gnaw on it, what can you do? Pulls. And I’m not talking about stupid children who put everything they can get their hands on in their mouths. And not about pregnant women who suddenly want to taste chalk so much that they can scream. Therefore, they need it, although until that moment they had never experienced such a desire. The body, therefore, requires it. And if that’s the case, let them chew on it. Just not the chalk you use to write on blackboards in classrooms. Half of it is gypsum and some chemical additives. Let them chew on children's crayons. Moreover, they are not colored. After all, color, again, is a certain chemical additive. Let them chew on white crayons. Or, at worst, they scrape the whitewash off the walls. Although construction chalk is harmful. It happens that pregnant women even chip away at the plaster and chew it. This is their path, pregnant women. And it's not about them. But the point is that they are quite adults and, at first glance, normal people who eat chalk. It happens that they gobble up both cheeks. And not out of hunger, but out of some incomprehensible attraction. How to explain this, citizens? And what is the justification for eating chalk like this? And most importantly, is there any benefit from this, or just harm?

They say that chalk is useful. In limited quantities and from the pharmacy. This chalk is called calcium gluconate. You have a calcium deficiency and are prescribed this gluconate. But we are not talking about pharmacy chalk!?

Doctors say that people who eat chalk experience a lack of iron in their bodies. The body, they say, asks to compensate for this deficiency, so they eat chalk. But iron is found in many foods. In apples, for example. Isn't it better to eat a kilo of apples than to eat crushed chalk, which is added to the feed of pigs and cows? Although this chalk is food grade, the stomachs of cows and people are different.

Therefore, the need to chew chalk is an oddity. Deviation from the norm, albeit minor. And we need to fight and get rid of it, because chalk, although a neutral substance that does not affect metabolism and the functioning of internal organs, is not worth using as a food product. Even those that are mined in quarries or extracted from rocks are considered environmentally friendly.

What can happen from eating too much chalk?

Liming of vessels. Which over time can lead to cardiovascular diseases. And when interacting with gastric juice, chalk becomes like slaked lime, which corrodes the walls of the intestines. Not far from an ulcer or something worse. So it’s better to stop consuming chalk altogether. Or reduce it to a minimum, if you can’t do without it.

They also say that chalk helps with heartburn. So: this is all nonsense...
