Selenium is also present in many foods, which is the main source of selenium intake for most people. The selenium content of foods is mainly dependent on the selenium content of soil for plants, and selenium content of feedstuff for livestock. Selenium is an essential element for human health, but high levels are associated with numerous diseases.
