Re: Study: Selenium supplements may raise diabetes risk

The important point omitted here is the TYPE of Selenium used in the trial, whether organic or inorganic: selenium, selenomethionine, selenium yeast, sodium selenite, sodium selenate, dietary supplements containing selenium.

The typical American diet provides the average adult with about 80 to 150 micrograms of selenium per day, which is more than the newly revised RDA for selenium of 55 µ but less than one half of the amount considered optimal for utilization of the protective potential of selenium, especially for cancer prevention.
Accordingly, extradietary selenium supplementation is increasingly recommended by health professionals.
Pending the outcome of ongoing human cancer prevention trials, selenium supplementation is likely to be officially recognized as a means of lowering cancer risk. These developments raise the question as to WHICH FORM of selenium is the most desirable for supplementation. In addition, the quality and safety of the selenium supplements become matters of concern as well in these trials.
