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 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 normal human life, also known as indispensable 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 certain elements, 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, deafness, and mutism; cardiovascular diseases, hypertension, weakened immunity, cell mutations, tumor formation, and anemia in adults; and early aging and shortened lifespan in the elderly. This book provides a detailed account of the sources of these 14 essential trace elements, their metabolism in the human body, physiological functions, required amounts, causes of deficiency, symptoms, prevention, treatment, and measures to prevent toxicity. It is a nutritional reading material for the general public, especially middle-aged and elderly people to maintain health.
