Selenium is an essential trace element of fundamental importance to human health. The most abundant sources of selenium are Brazil nuts, seafood, meat and poultry People at risk of selenium deficiency include those with a restricted food intake (slimmers, vegetarians, the elderly), pregnant and lactating women, and those living in geographical regions with selenium depleted soils. It is recognised that soils in many areas of the world, including the UK, are deficient in selenium, often as a result of continual or intensive farming. This deficiency is manifest upwards through the food chain via plants and animals, culminating in man. A good example of this is Keshan disease, an endemic cardiomyopathy resulting from severely selenium depleted soil in the Keshan region of China-a problem that was eventually eliminated by the addition of a selenium supplement to dietary salt. In Scandinavian countries, selenium is added to agricultural fertilizers to increase depleted soil selenium levels, resulting in an increase in population average selenium intake from 30 to 90 microgm/day. Dietary selenium always occurs in an organic form (i.e. bound to an amino acid such as methionine or cysteine), whereas selenium in supplements may be organic or inorganic in form. The absorption of organic selenium (selenomethionine, selenocysteine) is generally more efficient than for inorganic selenium (e.g. sodium selenite), and the absorption of organic forms of selenium is not reduced by concurrent intake of vitamin C. Selenium levels are depleted by smoking or drinking alcohol.
