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 can 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 of the 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 are limb cramps (including during 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, seaweed, citrus fruits, cereals, vegetables... With 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. And the sooner the 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 have already been seriously damaged, prepare 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 indicated by dry pale skin, rapid fatigue and drowsiness, in some cases early gray hair, rapid pulse, and shortness of breath. In this case, you need not calcium-containing, but iron-containing products - this is primarily red meat (preferably dried), beef liver, hematogen. If, for ethical reasons, you do not eat animal products, you should take dietary supplements or vitamin cocktails with spirulina. 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 of clean chalk a day will not do any harm - however, it is worth emphasizing: just pure chalk.
Is it possible to eat school chalk, sold in stationery stores? It’s better not to – it contains plaster, glue, and sometimes dyes, and all this certainly will 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 essential microelements, since the child’s skeleton is formed from it. 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: pills still do not replace a balanced diet, but can only serve as a supplement 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 given the fact that fewer and fewer women are 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 of internal organs, and therefore eggshells as a source of calcium are a cleaner and more harmless product.
First of all, such a desire is explained by an acute deficiency of mineral elements in the body: iron, calcium, magnesium, and is also a sign of some disease.
To the common question: “is it possible to eat chalk?” doctors give a negative answer, since edible chalk is not sold here, and the insufficient number of minerals should be replenished through the consumption of foods rich in natural substances.
It is even more dangerous to eat school crayons, whitewash powder containing chemical additives, as well as chalk pebbles for rodents, which are not intended for humans.
Why do you want to eat chalk?
To find out the cause, you need to undergo a medical examination. The test results will determine which mineral intake and absorption is insufficient; in accordance with the diagnosis, the doctor will prescribe treatment. Perhaps he will simply recommend increasing consumption healthy products, rich in calcium, iron, or will prescribe medications ().
Pregnancy and chalk
Many women eat chalk in incredibly large quantities when carrying a child. This is caused by anemia, or low calcium content in food.
Is it possible to eat chalk during pregnancy, the composition of which is intended for whitewashing?
In no case. There is an accumulation of harmful chemical components: gypsum, lime, adhesive binder. Organism expectant mother exposed to poisoning, toxins reach the baby. This leads to the development of many diseases. The intestines, blood vessels, and respiratory tract are at risk.
Can pregnant women eat chalk used in school?
It is not possible for the same reason that it is harmful to the body. chemical composition. The desire to eat a piece will go away immediately if you fill your diet with healthy foods enriched with natural mineral and vitamin complexes.
Harmful to children
Can children eat school chalk?
If you see a child chewing on a piece of chalk, stop this behavior immediately. Such chalk is not at all absorbed by the body and is very toxic for a growing organism. 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 and other oral diseases.
Chalk dries the epithelium of the larynx, respiratory and digestive organs, promotes the formation of microcracks, where favorable conditions are created for the habitat 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: it is absorbed quickly and effectively only from natural products that contain all the mineral elements and vitamins. When eating chalk, there is a danger of sedimentation and concentration on the mucous membrane of blood vessels, deposits in the kidneys, liver, 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.
How can you replace chalk if you really want to eat it?
What kind of chalk can you eat?
Pharmaceutical companies produce calcium gluconate, which is an analogue of natural chalk, has a similar taste, but is practically safe for consumption. The pills won’t bring much benefit, but they will get rid of the addiction to chewing household chemicals.
Can a pregnant woman or child eat chalk that contains calcium gluconate?
It is possible and even necessary if you get the doctor’s approval. Small portions will not cause harm, but increased consumption of the drug can cause constipation, disrupt metabolism, lead to liming of the mucous epithelium, connective tissues and even the development of terrible diseases: pancreatitis, heart attack.
For the human body, chalk is not only unnecessary, but also unhealthy. And if you really want it, this is a violation of taste preferences. This may also be signs of iron deficiency anemia, in which hemoglobin synthesis is impaired due to iron deficiency.
Why is there a need to use chalk?
You want to eat a piece of chalk or lime when there is not enough calcium in your body. Calcium is the basis bone tissue and participates in water-salt metabolism. Calcium is able to normalize the excitability of the nervous system and muscles. With a monotonous diet, insufficient consumption of cottage cheese, cheese, milk, calcium deficiency may occur in the body. Peas, beans, buckwheat and oatmeal also contain calcium salts. However, calcium is best absorbed from fermented milk products, chicken eggs and milk. With a lack of vitamin D, its absorption deteriorates.
The absorption of calcium is directly affected by the amount of phosphorus entering the body. A person suffering from anemia may have the impression that consuming chalk will solve all problems. However, crayons cannot compensate for iron deficiency in the blood. When chalk begins to come into contact with the acidic environment of the stomach, it begins to turn into a kind of slaked lime, which has an extremely negative effect on the mucous membrane of the digestive organs. Calcium is deposited in the lungs and kidneys, pancreas, this can lead to pancreatitis. If you take chalk for a long time, you may develop diabetes mellitus, liming of blood vessels, and the appearance of kidney stones. This all in turn leads to the development of cardiovascular diseases. It happens that the need to eat lime or chalk is caused by a peculiar perversion of taste and a bad habit. It is not recommended to use chalk and lime, because it can disrupt intestinal functions, resulting in constipation and the risk of introducing an infection into the body.
Is it harmful to eat chalk?
A small piece of chalk, of course, will not do much harm. And if you really want to chew it, then you should choose chalk at least without harmful impurities and dyes. You can't eat construction chalk. It is a roughly processed material containing a lot of chemicals and impurities that are added to give it certain properties. Chalk for pets (rodents, parrots) can cause burping and for humans it simply tastes disgusting. Stationery crayons are also unsafe; glue and plaster are often added to them for hardness. It is best to eat natural chalk, which is mined in quarries or that which is extracted from rock. If the problem is a lack of iron in the diet, then it is necessary to include foods that are rich in this trace element. It is necessary to increase the consumption of the following foods: liver, veal, buckwheat, pomegranate, carrots, beets, kiwi and apples. These products can increase hemoglobin levels. Copper is also necessary for anemia, it promotes the absorption of iron and is found in green vegetables, egg yolks, apricots, cherries, figs and seaweed.
The need to eat chalk, lime or a mixture of clay and river sand (popularly called “pechnina”) indicates that a person has a very distorted taste. Chalk, pechnina, and lime are substances alien to the body, it does not absorb them, and their use not only does not bring any benefit, but can even cause some harm. Moreover, these substances can be contaminated, and “liver” is also difficult to remove from the body and is absolutely not absorbed by it.
As observations have shown, in some cases, such a perversion of taste affects people who have a violation of mineral metabolism in the body. This usually reveals a lack of calcium in the body. This most often happens in women during pregnancy and breastfeeding, and in children during periods of rapid growth and adolescence. But sometimes practically healthy people whose mineral metabolism is not impaired also eat chalk.
Calcium is needed not only for the formation of bone tissue, but also for the normal functioning of the nervous and muscular systems.
The need for calcium is high in the first years of a child's life. It is estimated that children between 1 and 6 years of age should receive approximately 1,000 milligrams of calcium per day. In the future, due to increased growth and intensive ossification process, the need for it increases. Children and adolescents from 7 to 17 years old require an average of 1,200-1,400 milligrams of calcium per day.
Adults need to get about 800 milligrams from food, and pregnant women and nursing mothers need 1,900 and 1,500 milligrams of calcium per day, respectively.
The body's absorption of calcium largely depends on the presence in food of various compounds that promote or inhibit absorption. For example, the absorption of calcium salts noticeably worsens if the food contains a lot of phytin, oxalic acid or an excess amount of fat. And it improves significantly when vitamin D is added to food.
There is a lot of calcium in milk, cottage cheese, feta cheese, and cheese. Almost half a liter of milk or 100 grams of cheese per day satisfies the needs of an adult. Calcium salts are also contained in rye bread, fruits, vegetables (especially white cabbage).
To restore the disturbed mineral balance, it is sometimes enough to create a correct diet. In some cases, the doctor prescribes calcium supplements.
However, following a diet containing a large amount of all the necessary moral salts and taking prescribed medications does not always completely eliminate the craving for chalk or “pechnina”. Obviously, this is a consequence of poor absorption of calcium salts. Increasing the dose of the drug usually has no effect. Therefore, in such cases, doctors usually prescribe vitamin D and fish oil in winter, and in summer they recommend spending more time in the air: this vitamin has the ability to be formed in the skin under the influence of ultraviolet rays. You can also add foods rich in vitamin D to your diet - cod liver, fish, eggs (yolk)

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 need of the body. In most clinical pictures, the cause lies in a deficiency of calcium or iron 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 a healthy lifestyle is now popular 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 fact is that in the modern world it is really difficult to find natural products that do not contain harmful components, while being abundant in substances necessary for the normal functioning of 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 of a mineral element in the body, 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 over a long period of time. Then not only the kidneys suffer, but also the blood vessels/arteries, gastrointestinal tract, lungs and other internal organs, as they become 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, gypsum, glue, and sometimes dyes. This is definitely not good for the body. Unrefined chalk or whitewash may contain bad substances in its composition. of different nature, 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 a calcium deficiency, then to some extent it can be absorbed, provided that the body has a sufficient amount of vitamin D, 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 health problems - 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 would be a good idea to get tested for the content of mineral substances - timely response to the body’s 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, in an interesting situation, are ready to experiment with their 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 a completely healthy woman without pregnancy pathologies 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 pregnancy is complicated by chronic diseases, then every second woman’s taste preferences change.
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.
