Trace Elements in Human Health

In this chapter, essential trace elements: boron, cobalt, chromium, copper, fluorine, iodine, iron, manganese, molybdenum, selenium, and zinc are presented. The role and characteristics of individual trace elements is described based on the most current research. These elements play an important role in human health and ensure proper functioning of various organs. Since they are not produced in the human body, their only source is food and nutrients. The effects of trace elements on human health depend on age, genetics, diseases, diet, lifestyle, and environment and these factors are discussed in the chapter. In line with trends in modern medicine, we emphasize an individualized approach based on selected examples. It would be desirable for modern medicine to prevent the toxic effects of trace elements in predisposed persons as well as establishing personalized dietary recommendations for some trace elements to optimize health status.
