"Brazil nuts, seeds, green vegetables and certain mushrooms contain significant amounts of selenium in areas in which selenium is present in the soil. Fish and meat may also be good sources if the animals dwell in selenium-rich environments. The USA sets the maximal daily selenium allowance as 400 μg per day in adults, in order to avoid chronic toxicity (see below)."
"Selenosis, the condition caused by chronic selenium excess, results in deleterious effects on the skin, GI tract, and nervous system 2."
"Selenium is essential for the synthesis of selenocysteine, a rare amino acid in which the normal sulfur of cysteine, has been substituted by selenium. This is needed for the production of twenty-five different selenoproteins (proteins containing selenium) coded for by the human genome 2."
