Increased risk for developing various diseases has also been noted, even when certain individuals lack optimal amounts of selenium, but not enough to be classified as deficient.For some time now, it has been reported in medical literature that a pattern of side-effects possibly associated with cholesterol-lowering drugs (e.g., statins) may resemble the pathology of selenium deficiency. Diagnosis
Reference ranges
The European Food Safety Authority (EFSA) recommends a dietary allowance of 70 μg per day selenium intake for adults. In the US, the Dietary Reference Intake for adults is 55 µg/day. In the UK it is 75 µg/day for adult males and 60 µg/day for adult females. 55 µg/day recommendation is based on full expression of plasma glutathione peroxidase. Selenoprotein P is a better indicator of selenium nutritional status, and full expression of it would require more than 66 µg/day. Epidemiology and prevention
Selenium deficiency is uncommon, but regions in China, Europe, Russia and New Zealand have low levels of selenium in croplands and diet. The worldwide prevalence of selenium deficiency is however predicted to rise under climate change due to the loss of selenium from croplands. These diseases are most common in certain parts of China where the intake is low because the soil is extremely deficient in selenium. Studies in Jiangsu Province of China have indicated a reduction in the prevalence of these diseases by taking selenium supplements. In Finland, selenium salts are added to chemical fertilizers, as a way to increase selenium in soils. Dietary supplements may utilize sodium selenite, L-selenomethionine or selenium-enriched yeast.
