Selen-
The term "selen-" refers to chemical compounds that contain selenium, a trace element essential for human health. Selenium is a vital nutrient that plays a key role in various physiological processes, including antioxidant defense, immune function, and thyroid hormone metabolism.
Importance of Selenium
Selenium acts as an antioxidant by preventing damage to cells caused by free radicals. It helps protect the body from oxidative stress and inflammation, which are linked to chronic diseases such as cancer, heart disease, and cognitive decline.
Health Benefits
Selenoproteins are a group of proteins that contain selenium and are essential for various biological functions. They play a crucial role in the regulation of thyroid hormone metabolism, DNA synthesis, and immune response. Adequate selenium intake is associated with a reduced risk of certain types of cancer, improved immune function, and better cognitive health.
Sources of Selenium
Selenium is found in a variety of foods, including Brazil nuts, seafood, organ meats, poultry, eggs, and dairy products. The amount of selenium in plant-based foods depends on the selenium content of the soil where they are grown. Selenium supplements are also available for individuals who may not get enough from their diet.
Deficiency and Toxicity
Selenium deficiency is rare in the general population but can occur in regions with low soil selenium levels. Symptoms of deficiency may include fatigue, muscle weakness, and cognitive decline. On the other hand, excessive selenium intake can lead to toxicity, resulting in symptoms such as hair loss, gastrointestinal disturbances, and neurological issues.
