Recognizing the importance of good nutrition for physical and mental status, the Department of Defense asked the Institute of Medicine to guide the design of the nutritional composition of a ration for soldiers on short-term, high-stress missions. Nutrient Composition of Rations for Short-Term, High-Intensity Combat Operations considers military performance, health concerns, food intake, energy expenditure, physical exercise, and food technology issues. The success of military operations depends to a large extent on the physical and mental status of the individuals involved. Appropriate nutrition during assault missions is a continuous challenge mainly due to diminished appetites of individuals under stress. Many less controllable and unpredictable factors, such as individual preferences and climate, come into play to reduce appetite. In fact, soldiers usually consume about half of the calories needed, leaving them in a state called "negative energy balance." The consequences of being in negative energy balance while under these circumstances range from weight loss to fatigue to mental impairments. An individual's physiological and nutritional status can markedly affect one's ability to maximize performance during missions and may compromise effectiveness. With the number of these missions increasing, the optimization of rations has become a high priority.

Written by a team from the U.S. Army's Combat Feeding Directorate at the Natick Research, Development and Engineering Center, this technical volume represents a comprehensive guide to how the military designs, processes, customizes, packages and distributes highly palatable, long shelf-life food products for field personnel. The book offers new data on numerous technologies used to solve problems such as nutrient densification, lightweighting, novel thermal processing, and long-term quality preservation in delivering appetizing foods and more. Testing techniques are explained for evaluating sensory qualities of foods and their effects on physical and cognitive performance.

The present study was conducted by an ad hoc subcommittee of the Committee on Military Nutrition Research. The Subcommittee on Technical Specifications for a High-Energy Emergency Relief Ration was established by the Food and Nutrition Board of the Institute of Medicine in response to a request from USAID and DOD to develop technical specifications for a product for use in food relief after natural disasters or other emergency situations around the world. The specifications are to be used by both agencies in their calls for bids from U.S. food manufacturers to supply such a product.

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.

This book reviews the research pertaining to nutrient requirements for working in cold or in high-altitude environments and states recommendations regarding the application of this information to military operational rations. It addresses whether, aside from increased energy demands, cold or high-altitude environments elicit an increased demand or requirement for specific nutrients, and whether performance in cold or high-altitude environments can be enhanced by the provision of increased amounts of specific nutrients.

Eating enough food to meet nutritional needs and maintain good health and good performance in all aspects of lifeâ€"both at home and on the jobâ€"is important for all of us throughout our lives. For military personnel, however, this presents a special challenge. Although soldiers typically have a number of options for eating when stationed on a base, in the field during missions their meals come in the form of operational rations. Unfortunately, military personnel in training and field operations often do not eat their rations in the amounts needed to ensure that they meet their energy and nutrient requirements and consequently lose weight and potentially risk loss of effectiveness both in physical and cognitive performance. This book contains 20 chapters by military and nonmilitary scientists from such fields as food science, food marketing and engineering, nutrition, physiology, psychology, and various medical specialties. Although described within a context of military tasks, the committee's conclusions and recommendations have wide-reaching implications for people who find that job-related stress changes their eating habits.

On July 9-10, 2014, the Institute of Medicine's Food Forum hosted a public workshop to explore emerging and rapidly developing research on relationships among the brain, the digestive system, and eating behavior. Drawing on expertise from the fields of nutrition and food science, animal and human physiology and behavior, and psychology and psychiatry as well as related fields, the purpose of the workshop was to (1) review current knowledge on the relationship between the brain and eating behavior, explore the interaction between the brain and the digestive system, and consider what is known about the brain's role in eating patterns and consumer choice; (2) evaluate current methods used to determine the impact of food on brain activity and eating behavior; and (3) identify gaps in knowledge and articulate a theoretical framework for future research. Relationships among the Brain, the Digestive System, and Eating Behavior summarizes the presentations and discussion of the workshop.
