Selenium
The selenium concentration in body fluids and tissues are directly related to selenium intake. The selenium concentration in Scandinavian food is low, and the concentration
in Norwegian bovine milk is about 11 ug/l (own results, 2006), and 37 ug/l in the US . For plant products the situation is even worse; the selenium concentration
in wheat flour (whole grain) is less than 20 ug/kg in Norwegian wheat (own results), compared to 707 ug/kg in the US.
