The series volumes are not the outcome of a symposium. Rather, each editor has the potential to examine a chosen area with a broad perspective, both in subject matter as well as in the choice of chapter authors. The international perspective, especially with regard to public health initiatives, is emphasized where appropriate. The editors, whose trainings are both research and practice oriented, have the opportunity to develop a primary objec- tive for their book; define the scope and focus, and then invite the leading authorities from around the world to be part of their initiative. The authors are encouraged to provide an overview of the field, discuss their own research and relate the research findings to potential human health consequences. Because each book is developed de novo, the chapters can be coordinated so that the resulting volume imparts greater knowledge than the sum of the information contained in the individual chapters. Clinical Nutrition of the Essential Trace Elements and Minerals, edited by John D. Bogden and Leslie M. Klevay, exemplifies the mission ofthe Nutrition and Health series. Drs. Bogden and Klevay provide the reader with a unique perspecti ve and focused view of the importance ofthe essentiality of trace elements and minerals for optimal health as well as their requirements and functions in specific disease conditions. By including an extensive review ofthe basic concepts ofm ineral metabolism, consumption patterns over the history of Man, assessment tools, and safety issues, this text gains in importance as a valuable resource for students as well as those who are practicing health professionals. The text also includes critically important chapters that discuss the requirements ofthese essential nutrients during adolescence, pregnancy, and lactation, and in the elderly. Medi- cally related professionals will certainly find the chapters related to the genetic diseases that affect mineral metabolism of particular importance to their practice. Additional chapters provide in-depth reviews of the functions of minerals and their roles in the endocrine, cardiovascular, gastrointestinal, immune, skeletal, and ocular systems of the body. This volume is of particular importance because it includes understandable chap- ters in highly technical areas written by the leading authorities of their fields of research. Thus, Clinical Nutrition of the Essential Trace Elements and Minerals represents a comprehensive, up-to-date resource for undergraduate, graduate, and medical students, nutrition and public health educators, practicing physicians, and other health care provid- ers as well as clinical and laboratory researchers.

NJ vii FOREWORD As we cross from one century into another, a comprehensive and authoritative presen- tation of knowledge and science of the biology of trace elements and minerals not only fills a great need, but also represents growing recognition of the importance of nutrition science for its impact on health and policy. The first half of the last century was an era of discovery in nutrition with all of the vitamins discovered, culminating in the descrip- tion of the structure of vitamin Bl2 in 1947. No less important was the elucidation of the biological and nutritional essentiality of many minerals leading to an appropriate place in our list of recommended nutrients for health. But it was in the second half of the 20th century that the definitions ofe ssential nutrients and essential minerals underwent a most important change and even a paradigm shift as knowldge increased of the relationship between mineral nutrition and chronic degenerative disease. The history of mineral biology in the past three decades includes the important discoveries which have led to a virtual explosion in knowledge and understanding of the importance of these nutrients in health and disease as is so well documented in the second half of this timely text. The discovery of binding proteins which were regulatory in the metabolism of minerals, of cellular receptors, and of nuclear receptors, binding sites regulating the expression of macromolecules critical to human biology exerted by trace minerals, and the remarkable improvements in instrumentation and chemical measuring precision have put mineral nutrition research at the forefront of the nutritionallbiological revolution. Now the prom- ise of plant biotechnology adds further elements to the projection of beneficial changes in our food supply. These enhancements in knowledge have permitted a much more science-based approach to some of the most important health problems in the world, including a better understanding of iron absorption and metabolism leading to better ways of preventing the most common nutritional deficiency in the world, iron deficiency. A better under- standing of the role of zinc in growth and development and enzyme function and metabolism has permitted that mineral to take its place among those that are targeted for important interventions in worldwide problems of child undernutrition. A better understanding ofthe many functions ofc opper in biology and metabolism have permitted that nutrient to be added to the essential nutrients as a factor in our understanding of heart disease and diet-heart interactions. Clinical Nutrition oft he Essential Trace Elements and Minerals sets a high standard for presentation of the scientific bases for the importance of minerals in human biology and health and will thereby contribute in a major way to the appropriate application of science for improved public health and preventive nutrition. No less important will be its contribution to establishing the foundation for moving the science in this important field even further. Irwin Rosenberg, MD United States Department ofA griculture, Human Nutrition Research Center on Aging, Tufts University, Boston, MA ix PREFACE There is widespread interest in nutrition among health professionals and the general public. Newspapers, general circulation magazines, television, and the internet are a daily source of nutrition information, but much of it is inaccurate and misleading. The public is frequently confused about specific nutrition issues, and many people turn to their health care providers as a source for accurate and up-to-date advice. However, physicians, nurses, registered dietitians, and other health care providers need sources of accurate, clinically relevant, and current information in order to provide sound guidance to their patients. Perhaps the greatest need is for a comprehensive book on trace element and mineral nutrition. Recent confusion among both health care providers and the general public about the use of zinc lozenges to treat the common cold and chromium supplements to enhance muscle mass are two examples of the need for reliable information. The target audience for Clincial Nutrition oft he Essential Trace Elements and Minerals is the health professional: physicians, registered dietitians, nurses, nutrition researchers, and college and university faculty who teach nutrition and/or medicine. However, it is also intended as a text for students in the health sciences. Clinical Nutrition of the Essential Trace Elements and Minerals has been written to provide up-to-date information, and should be useful as both a text and a reference for those in the field of nutrition. Other books on this topic take an approach that disperses information about specific clinical topics throughout the text by element. In contrast, Clinical Nutrition of the Essential Trace Elements and Minerals employs a more practical and useful approach- discussing, within a chapter, all of the essential elements relevant to a specific condition or group of diseases. Each chapter focuses on the clinical importance of the nine trace elements currently considered to be essential: chromium, copper, fluoride, iron, iodine, molybdenum, man- ganese, selenium, and zinc. The chapters also include discussion of the three major essential dietary minerals: calcium, magnesium, and phosphorus, where appropriate. Discussion of other trace elements and minerals is provided where relevant to a specific disease or condition. Each chapter is a review of current knowledge with an emphasis on human studies and clinical nutrition. Where useful, the authors include examples from their own research to explain key ideas and concepts. Tables and figures are used liberally to enhance learning by practitioners and students. The authors contributing to this volume are recognized as experts in their field as well as experienced teachers. Clinical Nutrition oft he Essential Trace Elements and Minerals consists of 21 chap- ters divided into four major sections. The first section contains seven chapters and dis- cusses basic concepts, consumption, laboratory assessment, supplement safety, and deficiencies of the essential micronutrients and minerals. Unique features of this section are the inclusion of chapters on both prehistoric and current consumption of trace ele- ments and minerals in food and the epidemiology of trace element and mineral deficien- cies. The second section contains four chapters on trace element and mineral nutrition in healthy people, with chapters on pregnancy, lactation, adolescents, and older people. The third and largest section with ten chapters discusses trace element and mineral nutrition in various diseases, including: genetic, endocrine, skeletal, cardiovascular, kidney, gas- xi xii Preface trointestinal, infectious, surgical, and opthalmologic disorders. The final section contains an index and guide to the relevant literature. As editors, we are very excited about each of the chapters and the breadth of the content of this book. We believe that this text can improve the teaching of trace element and mineral nutrition to students and health professionals and enhance their ability to provide sound dietary and medical advice to their clients and patients.
