Preface

Selenium is an antioxidant substance that contributes to the growth and development of cells and strengthens the immune system. Selenium is found in the structure of selenoproteins, which help prevent cellular damage caused by free radicals.

It is known that trace elements have a role in various diseases, especially in wound healing and correction of the immune response. It has been determined by various studies that low selenium levels may be associated with mortality and morbidity.

In most diseases, the organism is under oxidative stress. Selenium-containing enzymes protect cells against lipid peroxidation and play a role in regulating inflammatory events. Therefore, administration of selenium may prevent cellular damage in patients.

This book contains comprehensive information about the effects of selenium and its various components, which are extremely important for human health, in the organism, its role in various diseases, and especially its importance in human health. The book includes contributions from leading scientists and experts in the field. In addition, the book provides a vital foundation and opportunities for future research on the relationship between selenium and human health. We would like to express our gratitude to all the authors for their excellent contributions.
