What is selenium?
Selenium is a trace mineral that is found in some meats, nuts, and seafood; although the best source for selenium is found in vegetables that are grown in soils containing selenium. Crops grown in the Dakotas and Nebraska are known to contain larger amounts of selenium, while certain areas in other parts of the world, such as China and Russia, are known to contain very little selenium. Brazil nuts are known to be extremely high in selenium, containing as much as 500 mg per ounce, while other foods such as cod and turkey, only contain about 30 mg per ounce. Next to Brazil nuts, tuna is the next best source for natural selenium, although the amount contained in three ounces of tuna, at about 60 mgs, is much less than a single ounce of Brazil nuts. What is Selenium Deficiency? Individuals who consume diets lacking in selenium, result in a selenium deficiency that may contribute to an increased risk of heart disease, thyroid problems, and an increased susceptibility to infections and illne
Selenium in Technology is a testing solution and in Health and Diet is a form of mineral. Please find below the answer for both –
Technology
Selenium is a portable software testing framework for web applications. Selenium provides a record/playback tool for authoring tests without learning a test scripting language (Selenium IDE). It also provides a test domain-specific language (Selenese) [1] to write tests in a number of popular programming languages, including C#, Java, Groovy, Perl, PHP, Python and Ruby. The tests can then be run against most modern web browsers. Selenium deploys on Windows, Linux, and Macintosh platforms.
Diet and Health
Selenium is a trace mineral, which is essential to good health. However, it is only needed in small amounts.
Some of the functions of selenium include, protecting our cells from free radical damage. It also helps to regulate thyroid function. And, plays a role in the immune system.
The selenium content of plant foods in our diet, is directly related to the soil concentration of selenium where the food was grown.
Selenium is a non-metallic element that carries the chemical atomic number 34. Commonly identified with the chemical symbol of SE, selenium is an example of an element that is considered to the important in the proper function of the body. Here are some facts about what selenium does in the body, and what foods can be consumed in order to ensure there is a proper amount of this important chemical element in the daily diet. First identified by Swedish chemist Jons Berzelius in 1817, selenium is among the chemical elements that help the body to make efficient use of oxygen. Working in tandem with vitamin E, selenium helps to remove toxins from the body. The element also contains properties that are thought to promote healthy chromosome development and function within the body, which is necessary to fight off the development of various types of cancers. The thyroid gland also benefits from the presence of selenium, with the element helping to regulate the functions of the gland. In fact,
Selenium is a naturally occurring mineral element that is distributed widely in nature in most rocks and soils. In its pure form, it exists as metallic gray to black hexagonal crystals, but in nature it is usually combined with sulfide or with silver, copper, lead, and nickel minerals. Most processed selenium is used in the electronics industry, but it is also used: as a nutritional supplement; in the glass industry; as a component of pigments in plastics, paints, enamels, inks, and rubber; in the preparation of pharmaceuticals; as a nutritional feed additive for poultry and livestock; in pesticide formulations; in rubber production; as an ingredient in antidandruff shampoos; and as a constituent of fungicides. Radioactive selenium is used in diagnostic medicine.
