Overview

Selenium deficiency is relatively rare in healthy well-nourished individuals. Few cases in humans have been reported.

Epidemiology and prevention

These diseases are most common in certain parts of China where the intake is low[1] 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.[2] In Finland, selenium salts are added to chemical fertilizers, as a way to increase selenium in soils.[3]
