The Importance of Selenium


Selenium is a trace mineral essential for our health. Even though our bodies need a little amount of it to function properly, many people fail to meet daily recommended dose and stay healthy. Namely, all selenium comes from the soil. If the soil lacks this essential mineral or does not have enough of it, the foods produced by that soil will show the same deficiencies. For that reason, people who only eat foods produced locally may show signs of low selenium in the body. This is especially the case when people live in the countries where the soil does not provide enough of selenium. On the other hand, people who eat processed food, usually experience lack of selenium. These deficiencies often express as problems with the immune system, increased levels of oxidative stress, and fertility problems. Namely, many studies reveal antioxidative effects of selenium on our health. In this way, lack of selenium may contribute to heart disease, atherosclerosis, viral diseases, inflammation, and other diseases that are caused by oxidative stress. On the other hand, our immunity greatly depends on selenium level. Therefore, low selenium might contribute to autoimmune disease and even cancer.
