What is the useful salt?
Humanity has been using salt since time immemorial, but the method of its production has changed little. Salt - a substance of natural origin - is produced by evaporation of sea water or is mined in mines and quarries from deposits of rock salt (halite). Halite was formed many millennia ago at the place of dried seas. Salt is made from it by cleaning.
The value of salt for the human body
Disputes about whether harmful or useful salt has been going on for a long time. To understand the usefulness of salt, it is worth remembering that table salt is sodium chloride. Without sodium, transmission of nerve impulses and muscle contraction would be impossible. When there is a shortage of this trace element in the body, a person may feel drowsiness and muscle weakness, and in more severe cases, a lack of coordination of movements. Chlorine is necessary for the production of gastric juice, since hydrochloric acid is formed using chlorine ions. And salt - almost the only source of chlorine for humans.
The body begins to fill the lack of salt from the reserves located in the muscle and bone tissue, 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 is needed
What amount of salt is needed for normal life? On average, it is 4-6 grams per day. However, we get salt with vegetables and various products (bread, cheese, etc.). Especially a lot of salt found in fast food. Therefore, its consumption is often much more than the daily norm, which is far from harmless. Salt entering the body in large quantities leads to fluid retention. The kidneys and the cardiovascular system suffer from this, and blood pressure rises. The least useful salt of type "Extra", in which there are practically no useful substances.
Recently, sea salt has been increasingly used in cooking. But is its use justified, than sea salt is useful? In contrast to the purified salt, in the sea (as well as in the crude stone) contains more than 80 useful trace elements. Therefore, in those countries where salt is evaporated from sea water (Japan, Spain, etc.), there are much less cardiovascular diseases and disorders of the nervous system.But the content of iodine in sea salt, despite popular opinion, is not very high. Therefore, if necessary, it is worth using iodized salt. By the way, such salt, like sea salt, cannot be subjected to heat treatment, otherwise they will lose their beneficial properties.
Salt in the home
Salt is used not only in food. In case of a rhinitis, doctors advise rinsing the nasopharynx with saline (0.5 tsp. Per 1 degree of water). For bruises and insect bites, apply vinegar-saline compresses. When coughing warm the chest with heated salt.
Salt is also a cosmetic. To strengthen the nails it is recommended to make salt baths. A mixture of honey and salt is a wonderful body scrub, which also has tonic properties.
