The ecological situation, lifestyle and malnutrition negatively affect human health. Therefore, in 2022, disease prevention, the most important part of which is the rationalization of nutrition, should be given special attention.
The inclusion of properly selected mineral elements and vitamins in the daily diet is not always possible. Deficiency can be replenished with the help of vitamin complexes or food supplements with selenium, which affects all types of immunity.
Content
It is an integral part of proteins, liposaccharides, enzymes. Known as an element of longevity. It is also part of the antioxidant enzyme glutathione, which protects body cells from damage and oxidative stress.
It was discovered by a Swedish scientist who studied the production of sulfuric acid at the beginning of the 19th century, according to Amilia Gripsholm.
He received his name from Selene (from the Greek Moon), as he was constantly with tellurium, which received the name Tellus - Earth. But only in the second half of the 20th century, it was recognized as vital for humanity.
It has a carcinogenic property - it slows down the development of malignant tumors. It is used to treat male fertility - it provides sperm motility. The element is also used for the synthesis of thyroid hormones. In addition, studies have shown that Se is able to protect the body from harmful substances such as lead, cadmium, thallium, and mercury.
Selenium, Se is a chemical element of the periodic table with atomic number 34. It belongs to group VI. Similar in chemical properties to arsenic.
Natural Se is rare. It is a mixture of six isotopes.The source of accumulation is most often igneous rocks or thermal waters. Se isomorphic impurities are characteristic of native sulfur and sulfides.
Se obtained chemically is amorphous, brick-red powder. Melts quickly, forms glassy soot.
Due to the type of chemical bonds, that is, the molecular structure, it exists in various allotropic forms:
Used by Se for electrophotographic copiers, as a toner for photographic manufacturers. Expands the range of black and white photographic images. It is widely used to give cast steel a fine grain structure.
It is also used in the production of essential medicines. Modern pharmacology recommends drugs for use, where Se forms compounds with bioligands (biological substances), for example, selenocysteine, selenomethionine, or divalent organic forms of Se. They are effective, safe, but expensive.
Attention! Labeling of drugs should be easy to read, understandable, reliable, not mislead consumers.
Selenium as a trace element is very important for the life of humans and animals.
Due to non-compliance with sanitary and epidemiological requirements for soil quality, people are prone to oncological and cardiovascular diseases. For prevention, treatment, compounds such as selenite or sodium selenate, included in various vitamin complexes, are used, and animal feed is enriched with this element.
According to research by the US Academy of Sciences, the human body needs quite a bit of Se per day to maintain health - 55 micrograms for adults, 70 micrograms for women during pregnancy and lactation, 15 - 30 micrograms for children, respectively, according to age.
You don't have to prescribe anything on your own. Exceeding or lowering the dosage should be done under the supervision of a specialist.
According to WHO, the allowable intake of selenium per day is 400 mcg. Exceeding this threshold can lead to undesirable consequences.
The element is not synthesized by the body, only comes from outside. 10-20 grams of Brazil nuts can satisfy the daily requirement. However, the opportunity to eat Brazil nuts every day is not available to everyone.
Selenium is also found in sea water and most seafood - fish, squid, shrimp, crabs, mussels, sea kale.
Important. During cooking, the content of all elements and salts is reduced, but if you consume at least 200 g of seafood per day, selenium deficiency can be avoided.
Se is concentrated in the kidneys of domestic animals - sheep, pigs. But eating 100-200 g of kidneys daily is not a pleasure for everyone.
Not the last position in the ranking of selenium-containing food products is occupied by cereals, especially germinated grains, wheat bran. A large amount contains bread made from wholemeal flour.And more is contained in the dough prepared on sourdough - it neutralizes phytin, which absorbs important micronutrients, including Selenium.
The necessary amount of a microelement to satisfy the daily dose contains some vegetables - radishes, beets, tomatoes, white cabbage, garlic. Among fruits - orange, among berries - raspberries, blueberries.
Satisfying the daily dose is almost impossible. Therefore, in order to maintain immunity and normal life, it is necessary to artificially introduce a small amount of a microelement.
Small amounts of a microelement are vital for a person. The main part is concentrated in the kidneys, liver, spleen, heart, male testes.
Useful facts:
The amount of selenium-containing food products depends on the quality of the soil. In Russia, the soil is systematically destroyed by fertilizers, the supply of Se is below the minimum in more than 80% of Russians.
After 45 years, deficiency increases greatly, which can lead to stroke, heart attack. Therefore, entering the Balzac age, you need to pay special attention to selenium.
BAA (biologically active additive) for food, round brown tablets with beige splashes. They help to strengthen the immune system, maintain a healthy state of the cardiovascular system.
Previously, many mistakenly assumed that Se is not important enough for the body compared to, for example, iron or fluorine. Today it is proved that the microelement performs the most important functions of the life of the body. It should be taken with food at 50-70 mcg daily.

It is usually found where there are natural layers of selenium ores. Sometimes it is observed in people living far from the mines, as a result of the pursuit of a healthy lifestyle or the uncontrolled use of drugs with this microelement
To protect yourself from excess, you must adhere to a healthy diet, monitor weight, sleep well.
In people living far from the sea, Selenium enters the body in small doses. The usual diet does not provide the daily need of the body, moreover, it can be poorly absorbed. Therefore, doctors recommend that adults take additional selenium-containing drugs.

Decades ago, Selenium was not a popular nutrient.
Today, scientists have proven that the trace element is crucial for health - it affects the activity of the components of antioxidant systems and the hormonal metabolism of the thyroid gland.

A constructive way out of the situation is to take vitamin complexes, biological supplements or other selenium-containing drugs.
Remember. Self-medication is dangerous. Reception must be agreed with a specialist.
