Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.

Dietary Components and Immune Function focuses on immune modulation, immune mediated disease resistance, immune changes due to AIDS, immune modulated cancer therapy, and autoimmune diseases as modified by dietary supplement, bioactive foods and supplements. The potential value of such approaches in maintaining wellness and preventing disease are addressed by examining their effects in vitro and in vivo on innate and adaptive immune responses. Emerging fields of science and important discoveries relating to early stages of new nutriceuticals in cancer prevention, prior to clinical trials are also covered. This volume represents a single source of material related to nutriceuticals and their constituents as they relate to cancer therapy and prevention. As such the book will be essential reading for nutritionists, pharmacologists, health care professionals, research scientists, cancer workers, pathologists, molecular or cellular biochemists, physicians, general practitioners as well as those interested in diet and nutrition in disease resistance via immune regulation.

It is a pleasure to write the foreword to Nutrition and Table 1 Nutritional Status and Outcome of Infection Immunology: Principles and Practice. In fact, this book comes at a timely moment, when the impact of nutrition and Definite adverse outcome immunology is being widely felt because of the AIDS epi Measles, diarrhea, tuberculosis demic. This is particularly of note in Africa, where large Probable adverse outcome HIV, malaria, pneumonia sums of money are being spent on nutritional intervention Little or no effect programs in the hopes of improving immune responsive Poliomyelitis, tetanus, viral encephalitis ness. We should not forget, however, early advances in our Note: HIV= human immunodeficiency virus understanding of protein energy malnutrition (PEM). PEM can be used as a model to understand the nutritional basis of immunity, as well as the immunological influences on nutri tional status. Despite advances in agricultural production, tance. However, both in vitro studies and tests in laboratory PEM continues to affect hundreds of millions ofthe world's animals may have little resemblance to what is experienced population. The functional impact of undernutrition varies in humans under field conditions. from mild morbidity to life-threatening infection.

This book demonstrates that nutrients play a direct role as co-factors and regulators of the immune system. The book also shows that modulating the immune response with nutrients can provide a fundamental approach to preventive medicine.;Containing nearly 2300 bibliographic citations as well as illustrative figures, tables, and micrographs, this book is designed to be of interest to clinical immunologists, immunology and vitamin researchers, nutrition specialists, paediatricians, neonatologists, and upper-level undergraduate, graduate, and medical school students in these disciplines.

The activities of the Food and Nutrition Board's Committee on Military Nutrition Research (CMNR, the committee) have been supported since 1994 by grant DAMD17-94-J-4046 from the U.S. Army Medical Research and Materiel Command (USAMRMC). This report fulfills the final reporting requirement of the grant, and presents a summary of activities for the grant period from December 1, 1994 through May 31, 1999. During this grant period, the CMNR has met from three to six times each year in response to issues that are brought to the committee through the Military Nutrition and Biochemistry Division of the U.S. Army Research Institute of Environmental Medicine at Natick, Massachusetts, and the Military Operational Medicine Program of USAMRMC at Fort Detrick, Maryland. The CMNR has submitted five workshop reports (plus two preliminary reports), including one that is a joint project with the Subcommittee on Body Composition, Nutrition, and Health of Military Women; three letter reports, and one brief report, all with recommendations, to the Commander, U.S. Army Medical Research and Materiel Command, since September 1995 and has a brief report currently in preparation. These reports are summarized in the following activity report with synopses of additional topics for which reports were deferred pending completion of military research in progress. This activity report includes as appendixes the conclusions and recommendations from the nine reports and has been prepared in a fashion to allow rapid access to committee recommendations on the topics covered over the time period.

The science of animal nutrition has made significant advances in the past century. In looking back at the discoveries of the 20th century, we can appreciate the tremendous impact that animal nutrition has had on our lives. From the discovery of vitamins and the sweeping shift in the use of oilseeds to replace animal products as dietary protein sources for animals during the war times of the 1900s-to our integral understanding of nutrients as regulators of gene expression today-animal nutrition has been the cornerstone for scientific advances in many areas. At the milestone of their 70th year of service to the nation, the National Research Council's (NRC) Committee on Animal Nutrition (CAN) sought to gain a better understanding of the magnitude of recent discoveries and directions in animal nutrition for the new century we are embarking upon. With financial support from the NRC, the committee was able to organize and host a symposium that featured scientists from many backgrounds who were asked to share their ideas about the potential of animal nutrition to address current problems and future challenges.
