Selenium is a trace element which is naturally present in many foods. It is the constituent of many selenoproteins (Selenium+protein), that are essential for reproduction, thyroid function, DNA synthesis and protection against oxidative damage (oxidant defense) and infection. The role of selenocysteine in humans is being a cofactor of an enzyme called Glutathione peroxidase (GPx). It is also a powerpul partner of Iodothyronine deiodinase (ID) and thioredoxin reductase (TrxR) in thyroid metabolism.
Interpretation: Selenium deficiency has been found to play a role in human growth and reproduction. Deficiency also causes muscle weakness, anxiety and confusion. The most important result is depletion of the power of antioxidant system of the body. This causes susceptibility to many pathologies especially cancer and infections. Selenium depletion, results in fatique, mental fog, weakened immune system, muscle weakness and infertility. High Selenium is mostly because ingesting high doses of Selenium. Especially Brasil nuts are high in Selenium (Contains 90 micrograms of Selenium per nut). Normal plants may be high in Selenium if they grow on selenium rich soil, causing selenium accumulators which contain too much Selenium. Selenium also increases after inhalation of hydrogen selenite and selenium sulfide. Sodium selenite is the most toxic compound if ingested orally. High selenium causes difficulty in breathing, tremors, kidney failure, heart attacks, hair and nail loss or brittleness, skin lesions, nervous system disorders, skin rashes, nausea, diarrhea, mottled teeth.
