Features: This book reveals a colorful and mysterious world of trace elements. A "trace element" refers to a group of elements present in the human body that account for less than one ten-thousandth of the body's total weight. This group includes 41 elements such as iron, copper, iodine, and zinc. Among these, 14 elements—iron, fluorine, zinc, copper, iodine, tin, selenium, manganese, vanadium, nickel, molybdenum, chromium, and cobalt—are essential trace elements for the normal functioning of the human body, also known as essential trace elements. They are present in small quantities but play significant roles in maintaining normal life activities and are closely related to human birth, aging, illness, and death. If the body lacks or has an excess of any element, it can lead to conditions such as female infertility, male infertility; fetal malformations; delayed growth and abnormal development in infants and young children; low intelligence, dementia, and deafness; cardiovascular diseases, hypertension, weakened immunity, cell mutations, tumor formation, and anemia in adults; and premature aging and reduced lifespan in the elderly. This book provides a detailed account of the sources of these 14 essential trace elements, their metabolism and physiological functions in the human body, the recommended daily intake, the causes, symptoms, prevention, treatment, and management of deficiencies and toxicity. It is a nutritional reading resource for the general public, particularly middle-aged and elderly individuals, to maintain their health.
