Preface

This publication, Food Components to Enhance Performance, is another in a series of reports based on workshops sponsored by the Committee on Military Nutrition Research (CMNR) of the Food and Nutrition Board (FNB), Institute of Medicine, National Academy of Sciences. Other workshops or symposia have included such topics as nutritional needs in hot environments, body composition and physical performance, nutrition and physical performance, cognitive testing methodology, and fluid replacement and heat stress. These workshops form a part of the response that the CMNR provides to the Commander, U.S. Army Medical Research and Development Command, regarding issues brought to the committee through the Military Nutrition Division of the U.S. Army Research Institute of Environmental Medicine (USARIEM) at Natick, Massachusetts.

FOCUS OF THE REPORT

Optimal job performance without compromising the health and well-being of employees is the goal of employers no matter what the field of endeavor. Intermittent or prolonged physiological and psychological stressors that employees bring to the workplace have an impact not only on their own performance but on that of those with whom they work and interact. The very

significant effects of sleep deprivation on performance were clearly demonstrated in the recent report of performance decrements of medical interns and residents who needed to perform important medical tasks while on duty for extended periods of time, the Exxon Valdez accident, and similar military maritime accidents (National Commission on Sleep Disorders Research, 1993). The internal stressors an individual brings to his or her job are then compounded by the day-to-day physical and mental stresses of the job itself. Along with individuals engaged in the emergency and protective services in our communities—fire fighters, police, and emergency medical personnel—military personnel in combat settings endure highly unpredictable timing and types of stresses as well as situations that require continuing vigilance for hours or even days.

The U.S. Army has been led by concerns about individuals’ abilities to avoid performance degradation and the need to enhance mental capabilities in highly stressful situations to an interest in devising military ration components that could enhance soldier performance. The Committee on Military Nutrition Research was asked to assist a collaborative developmental program between scientists at the U.S Army Research Institute of Environmental Medicine (USARIEM) and the U.S. Army Natick Research, Development and Engineering Center (NRDEC) by evaluating the performance-enhancing potential of specific food components. On the basis of recent research, the Army scientists specifically requested that the CMNR review and comment on the potential for tyrosine, other amino acids, complex carbohydrates, caffeine, carnitine, choline, and long-chain fatty acids to help sharpen an individual’s performance under the strain of military missions. The committee was requested to indicate which if any of these food ingredients would offer the most promise for future research that would lead to the development of prototype ration components. Production of sufficient quantities of prototype rations to allow human testing of the effectiveness of such ration components in enhancing individual and unit performance in laboratory and controlled field settings could then proceed. The CMNR was asked to consider the research possibilities of each of the above listed food components and to also address six general questions about using food components to enhance performance in military combat settings. The questions that were posed to the committee are included in Chapter 1 of this report.

The views of military and nonmilitary scientists from the fields of neuroscience, nutrition, physiology, various medical specialties, and psychology on the most recent research concerning physical and mental performance enhancement in stressful conditions are included in this report. Although placed within the context of military tasks, the conclusions and recommendations presented in Chapters 1 and 2 of this report may have wide-reaching implications for individuals in any job setting.

HISTORY OF THE COMMITTEE

The Committee on Military Nutrition Research (CMNR) was established in October 1982 following a request by the Assistant Surgeon General of the Army that the Food and Nutrition Board of the National Academy of Sciences set up a committee to advise the U.S. Department of Defense on the need for and conduct of nutrition research and related issues. The committee’s tasks are to identify nutritional factors that may critically influence the physical and mental performance of military personnel under all environmental extremes; to identify deficiencies in the existing data base; to recommend research that would remedy these deficiencies and approaches for studying the relationship of diet to physical and mental performance; and to review and advise on standards for military feeding systems. Within this context the CMNR was asked to focus on nutrient requirements for performance during combat missions rather than requirements for military personnel in garrison. (The latter were judged as not significantly different from those of the civilian population.)

Although the membership of the committee has changed periodically, the disciplines represented have consistently included human nutrition, nutritional biochemistry, performance physiology, food science, and psychology. For issues that require broader expertise than exists within the committee, the CMNR has convened workshops. These workshops provide additional state-of-the-art scientific information and informed opinion for the consideration of the committee in their evaluation of the issues at hand.

COMMITTEE TASK AND PROCEDURES

In May 1992, personnel from the USARIEM requested that the CMNR examine the current state of knowledge concerning the potential of a number of food components to enhance performance in military combat settings. This request originated from a Science and Technology Objective (STO) to prevent performance degradation of the soldier under the stress of sustained field operations as part of the overall initiative—“The Soldier as a System.” This initiative recognizes the importance of all aspects of the soldier’s equipment and person as important in moving toward enhanced capabilities necessary for the future (see Chapter 3; Army Science Board, 1991).

The committee was aware of the large volume and the diversity of quality of the scientific literature on the topic of performance enhancement. It decided that the best way to review the state of knowledge in this disparate area was through a workshop at which knowledgeable researchers could review published research with the committee. Such a workshop would enable the

×

CMNR to review the adequacy of the current research and to identify gaps in the knowledge base that might be filled by future research.

A subgroup of the committee met in May 1992, determined the key topics for review, identified speakers with expertise in these topics, and planned the workshop for November 1992. Invited speakers were asked to prepare a review paper on their assigned topic for presentation and publication and to make specific recommendations in response to several questions posed to them prior to the workshop. The CMNR also believed that it would be beneficial to include a review of earlier and ongoing military research. Scientists at USARIEM and NRDEC participated in the workshop, resulting in a well-rounded agenda.

At the workshop, each speaker gave a formal presentation, which was followed as time allowed by questions and a brief discussion period. The proceedings were tape-recorded and professionally transcribed. At the end of the presentations, a general discussion of the overall topic was held. Immediately after the workshop, the CMNR met in executive session to review the issues, draw some tentative conclusions, and assign the preparation of draft reviews and summaries of specific topics to individual committee members. Committee members subsequently met in a series of working sessions and worked separately and together using the authored papers and additional reference material to draft the summary and recommendations. The final report was reviewed and approved by the entire committee.

The summary and recommendations of the Committee on Military Nutrition Research constitute Part I of this volume, and Parts II through VI include the papers presented at the workshop. Part I has been reviewed anonymously by an outside group with expertise in the topic area and experience in military issues. The authored papers in Parts II through VI are ordered in this volume as they were presented at the workshop. These chapters have undergone limited editorial change, have not been reviewed by the outside group, and represent the views of the individual authors. Selected questions directed toward the speakers and their responses are included when they occurred to provide a flavor of the workshop discussion. The invited speakers were also requested to submit a brief list of selected background papers prior to the workshop. These recommended readings, relevant citations collected by CMNR staff prior to the workshop, and selected citations from each chapter are included in the Selected Bibliography (Appendix C).

ACKNOWLEDGMENTS

It is my pleasure as Chair of the CMNR to acknowledge the contributions of the FNB staff, particularly the excellent technical and organizational skills of Bernadette M.Marriott, Ph.D., the FNB program director for the CMNR. Her assistance in organizing the workshop and in bringing the proceedings to the point of publication is greatly appreciated. I wish to acknowledge as well the fine contributions by the workshop speakers and their commitment to participate and prepare detailed review papers on relatively short notice. The CMNR appreciates the assistance of COL Eldon W.Askew and others from the USARIEM, and Drs. C.Patrick Dunne and Irwin A.Taub of NRDEC for their assistance in identifying issues of concern to the military and obtaining the involvement of the military personnel who participated in the workshop. The assistance of Dr. Harris R.Lieberman in the planning and identification of participants is gratefully acknowledged. COL David Schnakenberg’s scientific expertise and his historical knowledge of relevant military studies contributed significantly, as in the past, to the success of the workshop. The critiques of the anonymous reviewers and Food and Nutrition Board liaison member, Johanna Dwyer, in addition to comments by FNB director Catherine Woteki, provided helpful insights in the development of this final document. The editorial efforts of Michael Hayes are gratefully acknowledged. The assistance of Valerie Breen, CMNR research assistant, and Donna Allen, CMNR project assistant, in word processing, editing, and proofreading this report is greatly appreciated.

Finally, I am grateful to the members of the committee who participated significantly in the discussions at the workshop and in the preparation of the summaries of the proceedings. I also I want to thank committee members who participated in the initial planning of the workshop and those who drafted initial summaries of sections of this report. In particular, I want to thank former committee members Edward S.Horton, John A.Milner, and James G. Penland. The commitment of the members of this committee, who serve without compensation to provide sound, timely recommendations for consideration by the military, is commendable. It is a pleasure to work with this dedicated group.

The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settings--among others--experience highly unpredictable timing and types of stressors.

This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.
