How useful is the salt?
Mankind has been using salt from immemorialtimes, but the way of its production has changed little. Salt - a substance of natural origin - is produced by evaporation of sea water or extracted in mines and quarries from deposits of rock salt (halite). Galite was formed many millennia ago in the place of the dried up seas. From it, sodium chloride is produced by purification.
The importance of salt for the human body
Disputes about whether the salt is harmful or usefullong. To understand the usefulness of salt, it is worth remembering that table salt is sodium chloride. Without sodium it would be impossible to transmit nerve impulses and contract muscles. When there is a shortage of this microelement in the body, a person can feel drowsiness and muscle weakness, and in more severe cases - a violation of coordination of movements. Chlorine is necessary for the production of gastric juice, since hydrochloric acid is formed with the help of chloride ions. And salt is practically the only source of chlorine for humans.
The body begins to fill the lack of salt withstocks located in the muscle and bone tissues, which can lead to their destruction (osteoporosis). Lack of salt leads to nervous disorders, digestive disorders, problems with the cardiovascular system. It is believed that completely without salt the human body can last no more than 10 days.
How much salt do you need
How much salt is needed for normallife? On average, it is 4-6 grams per day. However, we get salt also with vegetables, various products (bread, cheese, etc.). Especially a lot of salt is contained in fast food. Therefore, often its consumption is much more than the daily rate, which is far from being harmless. Salt, entering the body in large quantities, leads to fluid retention. From this, kidneys and cardiovascular system suffer, blood pressure rises. The least useful salt is the "Extra" type, in which there are practically no useful substances.
Recently, more and more oftencooking sea salt. But is its use justifiable, what is the use of sea salt? In contrast to the purified salt, in marine (as well as in unrefined rock) contains more than 80 useful microelements. Therefore, in those countries where salt is used (Japan, Spain, etc.) evaporated from sea water, there are much fewer cardiovascular diseases and disorders of the nervous system. But the content of iodine in sea salt, despite the widespread opinion, is not very high. Therefore, if necessary, it is necessary to use iodized salt. By the way, such salt, as well as sea salt, can not be subjected to heat treatment, otherwise they will lose their useful properties.
Salt in everyday life
Salt is used not only for food. With a cold, doctors advise washing the nasopharynx with saline solution (0.5 tsp per 1 of water). With bruises and bites of insects, acetic-salt compresses are applied. When coughing, warm the chest with warm salt.
Salt is also a cosmetic. To strengthen the nails is recommended to make a salt bath. A mixture of honey and salt is a wonderful body scrub, which also has toning properties.
