Selenium can prevent bird flu mutations.

  There is panic talk of the bird flu causing millions of deaths if it should mutate to a form that is transmissible human to human. Some experts believe that selenium deficiency may be a driving force for viral mutations. But the information is being misconstrued...giving many people false hopes.

  Selenium deficiency could possibly increase the risk of more virulent viral strains. Selenium is an antioxidant. Oxidative stress caused by insufficient selenium could cause changes to viral RNA.

  But this is based on theory, not facts.
