Dietary selenium is an essential trace mineral that plays several important roles in maintaining good health. Its functions in the body are diverse and crucial for various physiological processes.
One of the key roles of selenium is its function as an antioxidant. Selenium helps protect cells from oxidative damage caused by free radicals, which are unstable molecules that can damage cells and contribute to aging and the development of some diseases. By combating oxidative stress, selenium plays a role in the prevention of certain cancers, heart disease, and other conditions where oxidative stress is a contributing factor.
Selenium also supports the immune system. Adequate levels of selenium are important for the proper functioning of the immune system, helping the body to resist infections and other diseases. It contributes to overall immune health and resilience against pathogens.
Additionally, selenium plays a critical role in thyroid function. It is necessary for the production of thyroid hormones, which regulate metabolism and are important for growth, development, and overall metabolic health. Proper thyroid function is essential for maintaining energy levels, regulating body temperature, and supporting the body’s metabolic processes.
To ensure adequate selenium intake, include a variety of selenium-rich foods in your diet. Brazil nuts are one of the richest sources of selenium, and seafood, poultry, and whole grains are also good sources. These foods provide not only selenium but also other essential nutrients that contribute to a balanced diet.
While selenium deficiency is relatively rare, maintaining adequate selenium intake is important for overall health. Adequate selenium supports antioxidant defenses, immune function, and thyroid health. Including selenium-rich foods as part of a balanced diet can help reduce the risk of chronic diseases and contribute to long-term health and vitality. A diet that includes sufficient selenium, along with other essential nutrients, plays a significant role in supporting overall well-being and a healthy, active lifestyle.
