Symptoms Of A Selenium Deficiency

Selenium is considered an essential dietary mineral that helps protect the body from oxidative stress. Plant-based foods are typically the major source of this mineral in the diet, and the exact selenium concentration in a given food is determined by the soil in which it is grown. Although rare in the United States, selenium deficiency is common in China, where the soil is lower in selenium. Scientists estimate one billion individuals worldwide are currently living with a selenium deficiency. Individuals who have Crohn's disease are at an elevated risk of this particular issue, and individuals who are undergoing dialysis are also more likely to develop it.
