These derived from amount protect against Keshan disease plus body weight correction factor. On other hand, 40 30 calculated achieve two-thirds maximal plasma glutathione peroxidase activity assuming interindividual variability normal dietary selenium 16%. Further work is determine relationship between these nutritional standards actual around world.
