Selenium is a trace element that is essential to human and animal health. It is essential for the production of several enzymes, as well as for protection against oxidative stress and cancer. Selenium also plays a role in thyroid hormone metabolism and regulation of cell growth and differentiation.
Selenium is found in a variety of foods, including grains, nuts, and seafood. The amount of selenium in food depends on the soil in which it was grown and harvested, as well as its preparation method. Whole grains are a good source of selenium, but those that have been processed, such as white rice or flour, are generally low in selenium.
The main dietary sources of selenium include Brazil nuts, tuna, beef, turkey, eggs, and certain fruits and vegetables. A serving of two to three Brazil nuts can contain as much as 100-200 mcg of selenium.
Selenium is also available in a variety of forms, including tablets, capsules, and liquids. Supplements are available in different concentrations, ranging from 50 mcg to 200 mcg. A single daily dose of selenium should not exceed 400 mcg.
The major dietary source of selenium is plant foods. Plants absorb the element through their roots, and then it is passed along to the consumer in various forms. Vegetables, fruits, grains, and nuts are all rich sources of selenium. Fertilizers, pesticides, and other chemicals used in agriculture can affect the selenium content of crops.
The daily recommended intake of selenium depends on age, sex, and medical conditions. The Recommended Dietary Allowance (RDA) for selenium for adults is 55 mcg per day for women and 70 mcg per day for men. Pregnant and lactating women should increase their daily intake to 60 mcg and 75 mcg respectively.
Selenium deficiency is associated with an increased risk for several diseases, including thyroid problems, infertility, heart disease, cancers, and neurological disorders. Deficiency can also adversely affect the immune system, making people more vulnerable to various illnesses.
Because of its many health benefits, selenium has become a popular dietary supplement. It is important to note, however, that taking too much selenium can cause toxicity. It is recommended to not exceed the daily recommended RDA of selenium.
