The Many Phases of Selenium

چکیده
Selenium is one of the most interesting of all nutrients. It was first known for its toxicity and was then discovered to be an essential nutrient. The power of its antioxidant activity has been widely acclaimed. The importance of selenium in immune response and as an anticarcinogen has recently received a great amount of attention. In fact, selenium has been claimed to have a protective role in at least 50 diseases of humans (Reilly, 1996). However, Reilly pointed out the evidence is not yet convincing for many of the claims. Casey (1988) rightfully stressed that the claims of many selenophiles might be exaggerated. Selenium is not a panacea. However, there is evidence that selenium can have enormous health benefits for animals and humans.
