Скачать или смотреть Does your body need more Selenium?

In biological systems, selenium is an essential trace element, meaning that it is required by living organisms in small amounts for normal physiological functions. Selenium is a crucial component of selenoproteins, a family of proteins that have various roles in the body. These roles include antioxidant defense, thyroid hormone metabolism, immune system function, and reproductive health.

Dietary sources of selenium include fish, shellfish, meat, poultry, dairy products, and certain nuts and seeds. The selenium content in food can vary depending on the selenium content of the soil in which the plants or animals are raised. In some regions, where the soil is low in selenium, dietary supplementation or the consumption of selenium-rich foods may be recommended to prevent deficiency.

While selenium is essential for health, it's important to maintain an appropriate balance. Both selenium deficiency and excess can have adverse effects on health. Adequate selenium intake is generally achievable through a well-balanced diet, and supplementation is usually only recommended under specific circumstances and with the guidance of a healthcare professional.
