If the iodine deficiency suffers the most part of the population of Russia, then there is one microelement, the lack of which is practical for everyone! This is selenium.
According to the Institute of Nutrition of the Russian Academy of Medical Science more than 80% of the Russian population experience a deficit of selenium. To maintain health, we need very little selenium. The World Health Organization considers that a woman needs 55 micrograms per day, 70 mkg for a man, and 1 mkg of this substance for 1 kg of weight for children. It should be remembered that the micrograms that are measured are selenium, a thousand times less than a milligram, the traditional value of vitamin doses (1 g is 1000 mg and 1 mg is 1000 μg). But you can appoint yourself no more than 50 micrograms of selenium per day.
Unfortunately, food can not completely provide us with selenium. This substance enters the plants from the soil, in which it is extremely small in the territory of Russia. Moreover, selenium is additionally ruined by fertilizers and heavy metals. Poisoned earth contains a useful trace element in poorly digestible form.
Most of all, selenium is known as a microelement of longevity. Since not only protects the cell membranes from damage by aggressive forms of oxygen, but also actively helps vitamin E, a powerful antioxidant, to fully reveal its antioxidant potential. In addition, it turned out that he is able to protect our body from mercury, cadmium, lead, thallium and other harmful substances, satellites of modern civilization, flooded the environment.
At one time, this extremely important microelement even seemed to many scientists a real panacea for all diseases. He was prescribed in large and even gigantic doses. But after a while it became clear that the excess of this substance is no less harmful than its lack. So its use should be treated with extreme caution.
Selenium has a very strong anticarcinogenic effect, and not only prevents, but also stops the development of some malignant tumors.
It provides protection and motility to spermatozoa, and this is its quality is widely used in the treatment of male infertility.
But its main property is the normalization of the metabolism. It is necessary for the synthesis of iodine-containing hormones of the thyroid gland. Therefore, the fight against iodine deficiency is impossible against the background of selenium hunger.
Now in the pharmacy network there are more than 100 selenium-containing drugs. Interest in them is often heated artificially by the manufacturers themselves. And, of course, choosing what you need is not easy. OTC drugs leave, designed to make life easier for a person, is designed for a competent, consumer-interested consumer and a qualified pharmacist who is ready to give professional advice. But in fact, even from the annotation, we do not get all the necessary information.
So, when choosing a drug, pay attention to the following points.
What is its chemical structure. Preparations of the first generation contain selenium in the form of inorganic salts, which are poorly absorbed and often cause side effects: nausea, discomfort in the stomach. And, if selenium is a part of the preparation in this form (for example, sodium selenite, sodium selenate or selenium sulphide), then the packaging, as a rule, is silent about this. Modern pharmacology advises giving preference to drugs in which it is in the form of compounds with organic substances - bio-ligands (selenium-cysteine, selenium-methionine or divalent forms of selenium). They are safe, effective, but, alas, are expensive. The manufacturer of such additives always places on the package detailed information about the composition, for it has nothing to hide, it is proud of new technologies.

- Features of histophysiology of the thyroid gland of rabbits in the first half of pregnancy against the background of exposure to selenium-containing drugs
Chekurov IV. Scientific adviser: Dr. AB Abramova, Doctor of biological sciences, professor. FSEI HPE "Orenburg State Agrarian University", Orenburg Actuality. Selenium is a biologically active microelement, which is part of a number of hormones and enzymes, connected in this way with the activity of all organs, tissues and systems. Its presence in the body along with other microelements is necessary for
- HYGIENE OF PLANNING HUMAN SETTLEMENTS
Planning activities are of great importance for protecting the population from the harmful effects of emissions from industrial enterprises. According to SNiP P-60-75 "Planning, development of cities, towns and rural settlements", the territory for the construction of new and reconstruction of existing cities and settlements should be chosen taking into account the possibility of rational allocation of seats
- Physiological and hygienic assessment of basic microelements.
Microelements are chemical elements found in the tissues of the human body in concentrations of 1: 100,000 or less. To microelements also include chemical elements, in low concentrations contained in water, soil, etc. Some trace elements are absolutely necessary for the most important processes of the vital activity of the human body, as well as for the normal course of many metabolic processes

By its structure and composition, the bird's egg is perfect. A microscopically small living cell in a fertilized egg is capable of
- CHA-CHA: EIGHTH GIRL (a fairy tale about OK'SYUMORON)
We have such a custom in Cuba: when guests come, they should wash their glasses and gently stroke them and sprinkle sugar pellets there, saying: "I'll put the glass where I'll sit with my friends." But it's not that. Here the old Doña Ivanna Rossita Buernos (the Russian name was given to her nine months later, after the ship under the Russian flag entered the port of Havana) told a tale about an eight-legged
- MINERALS BETWEEN IRON
In countries where iodine deficiency is a public health problem, a legislative act on the continuous iodization of salt should be adopted and enforced. Many minerals are essential micronutrients and play a vital role in promoting growth, health and development. In this chapter, those that are most important when introducing
- Sanitary protection of water resources and water use objects
The most general provisions on the use and protection of underground and surface water sources are set out in the document "Fundamentals of Water Legislation". The document distinguishes between two categories of water use. The first relates to the use of a water body for domestic and drinking water supply (centralized or decentralized) and water supply to food enterprises

Function Iodine is an indispensable substrate in the synthesis of thyroid hormones, which are among the most important metabolic regulators (1). Thyroid hormones are needed for normal growth and development, to absorb oxygen in the cells and to maintain metabolic rate (2). Thyroid hormones are also of great importance for mental development and delay
Micronutrients should be added to the PP taking into account daily requirements. However, the information available on this issue is clearly insufficient, since there are no clearly established doses of trace elements for patients in intensive care units. Nevertheless, the often occurring micronutrient deficiency may be accompanied by some clinical manifestations and ultimately affect the results of treatment. Highly
