The environmental situation, lifestyle and unhealthy diet negatively affect human health. Therefore, in 2024, the prevention of diseases, the most important part of which is the rationalization of nutrition, should be given special attention.
The inclusion of correctly selected mineral elements and vitamins in the daily diet is not always possible. The 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 the cells of the body from damage and oxidative stress.
It was discovered by a Swedish scientist who investigated the production of sulfuric acid in the early 19th century, by amilia Gripsholm.
He received his name from Selene (from the Greek Moon), since he was constantly with tellurium, which received the name Tellus - Earth. But only in the second half of the XX century, it was recognized as vital for humanity.
Possesses carcinogenic properties - 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 Mendeleev's periodic table with atomic number 34. Belongs to group VI. The chemical properties are similar 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. Isomorphic Se impurities are characteristic of native sulfur and sulfides.
Se, obtained by chemical means, is amorphous, brick-red powder. It melts quickly to form a glassy soot.
Due to the type of chemical bonds, that is, the molecular structure, it exists in a variety of allotropic forms:
Se used for electrophotographic copiers, as toner for photographic manufacturers. Expands the range of black and white photographic images. It is widely used for giving fine grain structure to cast steel.
It is also used in the production of essential medicines. Modern pharmacology recommends medicinal products for use in which Se forms compounds with bioligands (biological substances), for example, selenocysteine, selenomethionine, or bivalent organic forms of Se. They are effective, safe, but expensive.
Attention! The labeling of medicinal products should be easy to read, understandable, reliable, not misleading consumers.
Selenium as a trace element is very important for the life of humans and animals.
Due to non-compliance with the sanitary and epidemiological requirements for the quality of the soil, people are prone to cancer, cardiovascular diseases. For prevention, treatment, compounds such as selenite or sodium selenate are used, included in various vitamin complexes, and animal feed is also enriched with this element.
According to research by the US Academy of Sciences, the human body needs very little Se per day to maintain health - 55 mcg for adults, 70 mcg for women during pregnancy and lactation, 15-30 mcg for children according to age.
You do not need to assign anything to yourself. Excess or decrease in dosage should be done under the supervision of a specialist.
According to WHO, the permissible 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 the 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, seaweed.
Important. During cooking, the content of all elements and salts is reduced, but if you consume at least 200 g of seafood per day, a selenium deficiency can be avoided.
Se is concentrated in the kidneys of domestic animals - rams and 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 sprouted grains, wheat bran. Contains large amounts of wholemeal bread. Moreover, more is contained in the dough prepared with sourdough - it neutralizes phytin, which absorbs important micronutrients, including Selenium.
The required amount of a trace element to meet the daily dose contains some vegetables - radishes, beets, tomatoes, cabbage, garlic. Among the fruits - an orange, among the berries - raspberries, blueberries.
Satisfying the daily dose is almost impossible. Therefore, to maintain immunity and normal life, it is necessary to artificially introduce a small amount of a trace element.
Small amounts of a trace element 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 Se supply is below the minimum for more than 80% of Russians.
After 45 years, the deficiency greatly increases, which can lead to stroke, heart attack. Therefore, entering the Balzac age, you need to pay special attention to selenium.
BAA (biologically active additive) to food, round brown tablets interspersed with beige. They help to strengthen the immune system, maintain a healthy state of the cardiovascular system.
Earlier, many people mistakenly assumed that Se was not important enough for the body compared to, for example, iron or fluorine. Today it has been proven that the trace element performs the most important functions of the body's vital activity. It should be taken with food, 50-70 mcg daily.

To protect yourself from excess, you need to adhere to a healthy diet, monitor your weight, and sleep well.
In people living far from the sea, Selenium enters the body in small doses. A normal diet does not provide the body's daily requirement, and it can be poorly absorbed. Therefore, doctors recommend that adults take additional selenium-containing drugs.
