Extract salt many millennia. At first way of its receiving was an evaporation of sea or salty lake water, burning of some plants. Now commercially develop fields of table salt on site of the dried-up ancient seas, receiving it from mineral of halite (rock salt).

Except direct use in food table salt is used as safe and widespread preservative for preservation of products as a component of production of hydrochloric acid, soda. Properties of table salt in the form of its strong solution in water long since used for a vydelyvaniye of skin.

Advantage of table salt

In an organism table salt is not formed therefore has to arrive surely from the outside, with food. Absorption of table salt almost completely happens in a small intestine. Its removal from an organism is carried out by means of kidneys, intestines and sweat glands. Excess loss of ions of sodium and chlorine arises at plentiful vomiting, heavy diarrhea.

Salt is the main source of ions of sodium and chlorine which contain in all bodies and fabrics for an organism. These ions play an important role in maintenance of water and electrolytic balance, including activating a number of the enzymes participating in regulation of this balance.

Useful properties of table salt also are that she participates in carrying out nervous impulses and muscular contractions. One fifth all amounts of daily requirement of salt go for production of hydrochloric acid of a gastric juice without which normal digestion is impossible.

At insufficient intake of salt in an organism at the person arterial pressure decreases, become frequent heartbeat, convulsive reductions of muscles, weakness appear.

In medicine solutions of sodium chloride apply to cultivation of drugs, to completion of deficit of liquid in an organism and desintoxication. At catarrhal diseases and antritis of saline solution wash out a nasal cavity and okolonosovy bosoms. Solutions of table salt have weak antiseptic properties. At locks enemas with solution of table salt which is capable to stimulate a peristaltics of a large intestine help.

The daily need for sodium chloride makes about 11 grams, 1 teaspoon of salt contains such amount of salt. In hot climate at the expressed sweating the daily need for table salt is higher, and makes 25-30 g. But often the real amount of the consumed salt exceeds this figure by 2-3 times. Salt caloric content almost zero.

At abuse of table salt arterial hypertension develops, kidneys and heart work in a busy schedule. At its excess contents in an organism water begins to be late that leads to developing of hypostases, headaches.

At diseases of kidneys, a liver and cardiovascular system, at rheumatism and obesity it is recommended to limit consumption of salt or to absolutely exclude it.

Poisoning with table salt

The use of salt in large numbers can not just have an adverse effect on health, but also be the cause of a lethal outcome. It is known that the lethal dose of table salt makes 3 g/kg of weight, these figures were established in experiments on rats. But poisoning with table salt more often happens at domestic animals and birds. Lack of water aggravates this situation.

When such amount of salt gets to an organism, the composition of blood changes and sharply arterial pressure rises. Because of redistribution of liquid in an organism work of a nervous system is broken, blood cells – erythrocytes, and also cells of vitals are dehydrated. Delivery of oxygen in fabric is as a result broken, and the organism perishes.
