Series Introduction
The overriding mission of theNutrition and Healthseries of books is to provide health
professionals with texts that are considered essential because each includes: (1) a synthe-
sis of the state of the science; (2) timely, in-depth reviews by the leading researchers in
their respective fields; (3) extensive, up-to-date fully annotated reference lists; (4) a
detailed index; (5) relevant tables and figures; (6) identification of paradigm shifts and
the consequences; (7) virtually no overlap of information between chapters, but targeted,
interchapter referrals; (8) suggestions of areas for future research; and (9) balanced, data-
driven answers to patient and/or health professionals’ questions that are based on the
totality of evidence rather than the findings of any single study.
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 are coordinated so that the resulting volume imparts greater knowledge than the
sum of the information contained in the individual chapters.
Handbook of Clinical Nutrition and Aging, edited by Connie Bales and Christine
Ritchie, clearly exemplifies the goals of the Nutrition and Healthseries. In fact, this is
the first book in the series to be designated a handbook because it is clearly the most
comprehensive volume available concerning the role of clinical nutrition in preserving
the health of the elderly—especially those suffering from chronic disease. As the editors
and chapter authors remind the reader, the fastest growing population in the United States
as well as globally is the oldest-old. This important text provides practical, data-driven
options to enhance this at-risk population’s potential for optimal health and disease
prevention with special emphasis on secondary disease prevention. The overarching goal
of the editors is to provide fully referenced information to health professionals so they
may enhance the nutritional welfare and overall health of older adults.
Bales and Ritchie have organized the volume into four major areas of focus: (1)
epidemiological findings that point to significant trends in nutritional aspects of aging,
(2) key fundamentals of geriatric nutrition, (3) the effects of aging on the senses and
effects of chronic diseases of aging on overall patient health concerns that can be affected
by nutrition—as well as nutrition’s potential to reduce disease progression, and (4) broad
clinical topics that include all of the major organ systems of the body in health and in
disease. Unique areas of focus include legal and ethical aspects of end-of-life care,
extensive review of herbal and nutritionally based dietary supplements, hearing and

nutrition, and cardiac rehabilitation programs including exercise and nutritional guid-
ance. Each chapter includes a discussion of the physiology of the condition, the effects
of aging, chronic disease(s), pertinent drugs or other treatments, relevant treatment guide-
lines, and the consequences of malnutrition and/or dietary recommendations and/or
supplemental sources of nutrients.
Handbook of Clinical Nutrition and Agingsets the benchmark for providing the most
critical data on drug/nutrient interactions with specific emphasis on drugs that affect
taste. This practical information is provided in extensive, well-organized tables that are
now accessible in this valuable volume. Understanding the complexities of the aging
process, drug use, physical debilities, and mental changes that also affect nutrient status
certainly is no simple task; the standards used can often seem daunting. However, the
authors are intent on assisting those unfamiliar with this field in understanding the critical
issues and important new research findings that can impact their fields of interest. The
editors have taken special care to use the same terms and abbreviations between chapters,
and to provide clear reference to relevant material between chapters. Moreover, the
Foreword by the well-acknowledged leader in the field, Dr. Robert Russell, provides a
clear overview of the critical importance of this volume to the understanding of clinical
nutrition and health of the aging population.
Drs. Bales and Ritchie have drawn from world renowned researchers to communicate
the relevant role of clinical nutrition in the health of aging populations. The authors have
worked hard to make their information accessible to health professionals who are inter-
ested in public health, geriatrics, nursing, pharmacy, and psychology, as well as nutrition-
related health issues. The well-referenced tables and figures as well as the detailed
references provide a great value to the reader. Many of the tables provide health profes-
sionals with guides to assessment in not only the nutritional status of the senior patient,
but also help in evaluating activities of daily living, mental performance, multiple drug
uses, and lists of other well-regarded resources. A very useful and unique component of
virtually each chapter is a final section on “Recommendations for Clinicians.”
In conclusion, Handbook of Clinical Nutrition and Agingprovides health profession-
als in many areas of research and practice with the most up-to-date, well-referenced, and
easy-to-understand volume on the importance of nutrition for optimal health during the
senior years. This volume will serve the reader as the most authoritative resource in the
field of clinical nutrition and aging to date and is a very welcome addition to the Nutrition
and Health series.

Foreword
Handbook of Clinical Nutrition and Aging, edited by Connie Bales and Christine
Ritchie, is a welcome addition to the Nutrition and Healthseries. The study of the role
of nutrition in the aging process has indeed “come of age.” Public interest on this subject
is at its highest peak—in hope that specific nutrients alone (or in combination) might play
a role in the prevention of chronic diseases of aging, and indeed of aging itself. In this
light, the Recommended Dietary Allowances (RDA) have been redefined according to
a new paradigm: instead of an RDA representing how much of a nutrient it may take to
protect a population against the deficiency state, it is now defined as how much of a
nutrient it takes to prevent a chronic disease or metabolic disorder from occurring. For
example, calcium and vitamin D requirements, in part, have been set according to the
amounts needed to prevent bone demineralization and osteoporosis.
It is amazing what the last 20 years have brought forth with regard to our knowledge
of nutrition in aging. We knew very little on this subject 20 years ago. We knew that
underfed rats lived longer than ad libitum fed rats, and we knew that severe obesity had
many dire health consequences—but that was about all. Over the last 20 years, the
importance of calcium and vitamin D in bone health has been defined, the importance of
B vitamins in cardiovascular disease has been demonstrated, and the roles that nutrients
play in the prevention of other age-related diseases, such as hypertension, cancer, eye
disease, and diabetes, have been better determined. But this continues to be a dynamic
area of research, as we are learning more each day, not only about new biochemical
mechanisms, but also the interplay between nutrients and the gene. Nutrients not only
control certain aspects of gene expression, but genetic endowment controls the response
to nutrients and diet that the individual is eating.
Twenty years ago it was thought that elderly people malabsorbed most nutrients. In
fact, we now know that this is not true, and that some nutrients may be superabsorbed with
age (e.g., vitamin A). One cannot generalize about nutrient needs in aging, e.g., that all
nutrients are needed in more or less amounts. The need is very specific and individualized
for each nutrient. For example, the need for vitamin D is greater with aging as a result of
decreased skin synthesis with ultraviolet light exposure, whereas iron requirements are
lower in postmenopausal women because of a loss of menstrual periods. Whereas it was
thought that riboflavin requirements would be lower with aging owing to decreased
energy expenditure, it has been shown that requirements for riboflavin are, in fact, steady
throughout the aging process.
All practitioners have a need to communicate with their patients, and increasingly this
requires a working knowledge of the role of nutrition in aging and age-related diseases.
TheHandbook of Clinical Nutrition and Agingis an up-to-date reference that provides
(1) the trends in nutrition and health in older adults, (2) the fundamentals of geriatric
nutrition, (3) geriatric syndromes related to nutrition (e.g., loss of taste, smell, and other
senses), and (4) specific clinical topics that are intimately related to nutritional status

(vascular disorders, pulmonary disease, cancer, musculoskeletal disorders, and so forth).
Physicians who wish to take an active role in educating their patients in the prevention
of chronic diseases associated with aging will find this book invaluable. Indeed, I hope
Handbook of Clinical Nutrition and Aging will appear on the bookshelves, not only of
medical libraries, but of a wide range of health practitioners.
