Selenium and human health in developing countries

Selenium is an essential trace element that plays a crucial role in human health. It is necessary for the proper functioning of various enzymes and proteins in the body, and it also acts as an antioxidant, protecting cells from damage caused by free radicals. While selenium deficiency is rare in developed countries where diets are typically diverse and balanced, it can be a significant health concern in developing countries.Inadequate intake of selenium through diet is the primary cause of selenium deficiency. This deficiency can lead to various health problems, including weakened immune function, increased risk of certain types of cancer, impaired cognitive function, and infertility. In developing countries, where malnutrition and limited access to nutritious foods are prevalent, selenium deficiency can be more common.
