Edible table salt is a universal mineral product that has been widely used in cooking, medicine, cosmetology and animal husbandry since ancient times.

The substance is a crushed transparent crystals with a pronounced taste and odorless. Depending on the purity, in accordance with GOST R 51574-2000, four grades are distinguished: extra, highest, first and second.

Salt can be finely and coarsely ground, various additives (iodine and other minerals) may be present in the substance. They give colorless crystals a grayish, yellow or even pink tint.

The daily requirement of salt for a person is 11 grams, which is about one teaspoon. In hot climates, the norm is higher - 25-30 grams.

Nutritional value of salt:

Edible salt is essential for the proper functioning of any organism, but it is very important to follow the recommended dosage. Lack or excess of a substance can cause significant harm to health. Let's see how NaCl is useful and harmful, how it is produced and where it is used.

The chemical composition of edible salt

The formula of edible salt is known to every student - NaCl. But you will not find absolutely pure sodium chlorine either in nature or on sale. The substance contains from 0.3 to 1% of various mineral impurities.

The composition of table salt is regulated by GOST R 51574-2000, which we have already mentioned above. Regulations:

According to the same GOST, salt is a crystalline bulk product without impurities, except for those associated with its production. Sodium chloride has a salty taste without foreign aftertastes. In the salt of the highest, first and second grade, there may be dark particles, within the content of iron oxide and a water-insoluble residue.

Salt production

Methods for the extraction of sodium chloride have not changed much since ancient times, and the production of the substance is available in almost every country. Let's name the main methods:

• Evaporation in special sea water tanks. In this case, the composition usually includes many useful elements, including iodine.
• Extraction from the bowels of the earth in quarries and mines - such a substance contains almost no moisture and impurities.
• Washing out and evaporating the brine, thus producing salt of the "Extra" variety, it is distinguished by the highest degree of purification.
• Collecting from the bottom of salt lakes, this is how self-planting salt is obtained, which, like sea salt, contains many mineral elements necessary for organisms.

Salt types

Today there are many types of salt. Among them there are, one might say, classic and exotic. The first have long been included in our diet. They have long been used to this day in cooking and the creation of various medicinal and cosmetic products:

• Rock salt - ordinary salt without special impurities.
• Iodized salt - sodium chloride, which is artificially enriched with iodine, it is very popular in regions where people suffer from iodine deficiency.
• Fluoridated salt - enriched with fluorine is good for teeth.
• Dietary salt has a reduced sodium content, which makes it taste slightly different.

Exotic types of salt are used in various cuisines of the world, including volcanic Indian salt, Himalayan pink, French smoked and many others. Such products differ in shades and the presence of specific flavors.

Beneficial features

Salt is not produced by the body on its own, but is very important in metabolic processes. Chlorine is needed for the synthesis of hydrochloric acid in the stomach, as well as other substances that are responsible for the breakdown of fat. And sodium ensures the correct functioning of the muscles and the nervous system, it affects the condition of the bones and the absorption nutrients large intestine.

Salt is involved in metabolic processes at the cell level, thanks to it the tissues receive the required amount of elements. The sodium-potassium compound is responsible for the penetration of amino acids and glucose through the cell membrane.

Salt is present in the diet of each of us, almost no dish can do without it. Sometimes this spice is used in small quantities even in dessert recipes. Nutritionists advise limiting its consumption to those who follow their figure. Why should white crystals be avoided? What is the calorie content of regular salt?

Salt on our table

Salt is a seasoning that has long been used for cooking. It is a white natural substance, sodium chloride. In everyday life, the expressions “stone”, “cooking”, “edible” salt are often used. What is the difference between these concepts? If you determine how many calories are in salt, is there a difference between its individual types?

In stores you can find salt in different forms:

• coarse or fine grinding, extra;
• purified or unrefined (stone);
• iodized, fluorinated and not additionally enriched;
• different shades, up to black (it all depends on the composition of the minerals).

Sea salt is recognized as the most useful, which contains almost half of the periodic table. If earlier it was used mainly for external treatment, today there is a purified marine product. How many calories are in table salt? Is it possible to use it in unlimited quantities?

Probably, for many consumers it will be a discovery that the calorie content of salt in 100 gr. equals zero. This indicator does not depend on the type of spice. However, this does not mean that white crystals can be eaten in unlimited quantities. The fact is that our body needs very little of this spice: scientists tend to figure 5 g per day.

If the calorie content of table salt is zero, then what is included in its composition and what kind of it will be most useful? White crystals contain about 0.1% fat and carbohydrates and no proteins at all. The basis of salt is sodium chloride, but this is far from the only mineral in the composition of the product. To a much lesser extent, it includes:

• ash;
• potassium;
• calcium;
• magnesium;
• iron;
• cobalt;
• manganese;
• molybdenum;
• zinc;
• copper.

Sometimes salt is artificially enriched with iodine or fluorine. Sea crystals have the richest composition. Today, consumers have many new varieties of salt at their disposal, for example, Himalayan pink, considered the most valuable, "Flower of the Sea", brown, etc. Everyone chooses according to their taste.

Our wicked friend

Although the crystalline product contains all the substances necessary for human existence, one should not exceed the daily allowance of 10-15 g. If a person consumes too much of this natural substance, he is threatened by diseases of the cardiovascular system, kidneys and stomach. However, the most surprising fact is that salt, the calorie content of which is zero, can lead to obesity! The spice, entering the body, stimulates human consumption of sugar and fats, impoverishing the diet and depriving it of foods rich in fiber and calcium. As a result, lovers of salt become owners of a whole bunch of diseases, the worst of which is diabetes.

But you don't have to give up salt completely. This threatens to upset the stomach (the spice supports its work, promotes the production of gastric juice), worsening of cardiac activity. Sodium is essential for the transmission of impulses through the nerves and muscles. This crystalline substance is very important for normal water-salt metabolism.

With its imbalance, the activity of the nervous system is disturbed, the person becomes irritable and restless.

Also, the most common symptoms of salt deficiency are:

• nausea;
• loss of taste;
• dizziness;
• weakness, drowsiness.

However, if you adhere to the norm in the use of spices, the body will always be in good shape.

From time immemorial, mankind has paid increased attention to such a seemingly simple substance as table salt. Indeed, such a large number of traditions and superstitions are not associated with any food product. People have been familiar with salt for about 10 thousand years. There were times when it was called a divine gift and valued more than gold. They fought for deposits, and because of its lack, “salt riots” often broke out. What is known about this controversial product? What is the calorie content of salt and what are the acceptable daily intake rates? Need to figure it out.

Benefit or harm

On the benefits and harms, there are the most ambiguous opinions. What is the calorie content of salt, what is its specific benefit or harm to the body? Such questions are increasingly of interest to the mass consumer. Scientists are still puzzling over “what is the point”, and huge amounts of money have already been spent on numerous studies. The purpose of one of the experiments was to study the effect of a certain amount of salt on human body. As a result, it turned out that, consumed in excess, it can negatively affect a person’s vision. This is explained by the fact that when eating salty foods, blood pressure, including eye pressure, can rise.

On the other hand, a decrease in consumption can lead to various cardiovascular abnormalities, the risk of myocardial infarction or stroke. Such serious consequences are caused by a lack of sodium in the body. With the complete rejection of salt, the activity of nerve cells is disrupted, insulin production decreases, and renin, on the contrary, increases. In this regard, a reasonable conclusion suggests itself that everything is good, that in moderation.

Salt as a symbol of vitality

Salt is not just a food seasoning that can improve the taste of a dish. This is a kind of magical symbol of vital energy, which is able to ward off misfortunes and sorrows, the evil eye and everything that negatively affects a person. In ancient times, during the offering, sacrificial animals were sprinkled with salt so that they would appease the gods with their taste. It has long been considered a talisman against evil spirits and evil spells.

Salt, in its ritual meaning, in combination with bread means financial well-being and wealth, it is not for nothing that on the wedding day the bride and groom are blessed with bread and salt. The expression "Bread and salt to you" also serves as a wish for wealth. In modern times, this is how important foreign guests at the government level are welcomed at the airport.

Such a different salt

Salt is a universal product. An interesting fact is that the calorie content of salt is zero. There are different colors (white, pink, black), large stone and extra, as well as iodized, fluoridated, dietary, marine. And this is not a complete list. The purpose of salt is completely different, one type can be salted with salads, another can be used for canning, the third - for medical purposes to prevent diseases.

According to the method of extraction and production, salt can be divided into 4 main types:

• Stone. It is mined in mines and quarries. It is the purest type of salt with a high content of sodium chloride (98-99%) and the minimum amount moisture.
• Cooking room. It is obtained from salty sources by evaporation, contains about 98-99.8% sodium chloride.
• Sadochnaya (marine). It is formed from sea or lake water by evaporation in specially equipped pools. It differs from other species by a lower content of sodium chloride, as well as taste properties.
• Self-planting. The least useful for the body due to the low content of sodium chloride, based on the name, it independently settles at the bottom of the salt lake, from where it is then extracted using special equipment.

Salt application

Salt, in other words, is one of the most important components that are used in the daily life of both people and animals. The calorie content of table salt is 0 kilocalories. This resource is also used in many industries. Salt is used as a basis for the production of chemical products (chlorine and from which various plastics are made, in particular PVC. In total, there are about 14 thousand areas of salt application.

As for table salt, which everyone eats, this substance is crystalline sodium chloride, each constituent element of which performs a certain vital function in the human body, despite the fact that the calorie content of salt is zero. The daily requirement is 10-15 grams. About seven kilograms come out per year. These indicators also depend on the conditions and type of climate. Water-salt exchange occurs more intensively in countries with a hotter climate.

Salt is the only natural mineral that the human body can absorb. Table salt is actively used for canning various kinds of seamings, since the brine tends to stop the vital activity of bacteria.

Useful properties and treatment with salt

Salt (calorie content per 100 grams 0 kcal), has good preventive, as well as medicinal properties. With nasal congestion and a runny nose, you can rinse your nose with a special solution. Pharmacies have a wide variety of irrigation preparations based on ordinary sea water. With inflammation of the throat, rinses are carried out (half a teaspoon of salt in half a glass of warm water). Salt also helps with the bites of various insects. To do this, you need to prepare a mixture, one to one, and lubricate the bite site. Itching and pain pass quickly. At home, salt is simply indispensable for mild poisoning, as it is able to remove poisons and toxins from the body.

Salt is widely used in the so-called balneology. treat a large number of various diseases, improve metabolic processes in the body, remove toxins and toxins. Baths are prescribed for diseases of the spine, arthritis, as well as disorders of the neurovascular system.

From the foregoing, we can conclude that zero calorie content (meaning edible salt) makes this product incredibly dietary, but unsuitable for eating in large quantities.

Food salt rich in vitamins and minerals such as: calcium - 36.8%, chlorine - 2595.2%, iron - 16.1%, cobalt - 150%, manganese - 12.5%, copper - 27.1%, molybdenum - 157.1%

Benefits of table salt

• Calcium is the main component of our bones, acts as a regulator of the nervous system, is involved in muscle contraction. Calcium deficiency leads to demineralization of the spine, pelvic bones and lower extremities, increases the risk of osteoporosis.
• Chlorine necessary for the formation and secretion of hydrochloric acid in the body.
• Iron is a part of proteins of various functions, including enzymes. Participates in the transport of electrons, oxygen, ensures the occurrence of redox reactions and activation of peroxidation. Insufficient consumption leads to hypochromic anemia, myoglobin deficiency atony of skeletal muscles, increased fatigue, myocardiopathy, atrophic gastritis.
• Cobalt is part of vitamin B12. Activates the enzymes of fatty acid metabolism and folic acid metabolism.
• Manganese participates in the formation of bone and connective tissue, is part of the enzymes involved in the metabolism of amino acids, carbohydrates, catecholamines; necessary for the synthesis of cholesterol and nucleotides. Insufficient consumption is accompanied by growth retardation, disorders in the reproductive system, increased fragility of bone tissue, disorders of carbohydrate and lipid metabolism.
• Copper is part of the enzymes that have redox activity and are involved in the metabolism of iron, stimulates the absorption of proteins and carbohydrates. Participates in the processes of providing tissues of the human body with oxygen. Deficiency is manifested by violations of the formation of the cardiovascular system and skeleton, the development of connective tissue dysplasia.
• Molybdenum is a cofactor of many enzymes that provide the metabolism of sulfur-containing amino acids, purines and pyrimidines.
