Food and Nutrition Board - Böcker

As the general public has become more aware of advances in nutrition, consumer demands for advice on matters of diet and disease have grown. This book offers recommendations to upgrade what were found to be largely inadequate nutrition programs in U.S. medical schools in order that health professionals be better qualified to advise and treat their patients. A comprehensive study of one-third of American 4-year undergraduate medical schools provided information on the current status of nutrition programs at each school. Conclusions were drawn and recommendations made from analysis of this gathered information. Questions examined in this volume include: Has medical education kept pace with advances in nutrition science? Are medical students equipped to convey sound nutritional advice to their patients? What strategies are needed to initiate and sustain adequate teaching of nutrition in medical schools?

Since its introduction in 1943 Recommended Dietary Allowances has become the accepted source of nutrient allowances for healthy people. These Recommended Dietary Allowances (RDAs) are used throughout the food and health fields. Additionally, RDAs serve as the basis for the U.S. Recommended Daily Allowances, the Food and Drug Administration's standards for nutrition labeling of foods. The 10th Edition includes research results and expert interpretations from years of progress in nutrition research since the previous edition and provides not only RDAs but also "Estimated Safe and Adequate Daily Dietary Intakes"--provisional values for nutrients where data were insufficient to set an RDA. Organized by nutrient for ready reference, the volume reviews the function of each nutrient in the human body, sources of supply, effects of deficiencies and excessive intakes, relevant study results, and more. The volume concludes with the invaluable "Summary Table of Recommended Dietary Allowances," a convenient and practical summary of the recommendations.

This series of individually authored chapters examines the nature and extent of scientific advances in the nutrition sciences and describes both future opportunities in the field and barriers to progress. Despite concern about declining attention to nutrition in universities and medical schools, the authors offer a bright and challenging future in nutrition research and training that should generate enthusiasm among young researchers and teachers for this indispensable component of biology.

This book focuses on nutrition services beginning in the preconceptional period and extending well beyond birth. It provides the rationale for the recommended nutritional services; briefly describes the necessary elements of these services; and indicates the personnel, knowledge, skills, and specialized education or training that may be needed to deliver them. It will be useful to policymakers, hospital administrators, directors of health centers, physicians in private or group practices, and others responsible for setting such standards and for overseeing health care services for expectant and new mothers and their infants.

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.

U.S. military personnel are required to adhere to standards of body composition, fitness, and appearance to achieve and maintain readiness--that is, the maintenance of optimum health and performance so they are ready for deployment at any moment. In 1992, the Committee on Military Nutrition Research reviewed the existing standards and found, among other things, that the standards for body composition required for women to achieve an appearance goal seemed to conflict with those necessary to ensure the ability to perform many types of military tasks. This report addresses that conflict, and reviews and makes recommendations about current policies governing body composition and fitness, as well as postpartum return-to-duty standards, Military Recommended Dietary Allowances, and physical activity and nutritional practices of military women to determine their individual and collective impact on the health, fitness, and readiness of active-duty women.

There has been intense interest recently among the public and the media in the possibility that increased intakes of "dietary antioxidants" may protect against chronic disease. Many research programs are underway in this area. Epidemiological evidence suggests that the consumption of fruits and vegetables may reduce the risk of both cancer and cardiovascular disease, and it has been hypothesized that this is due in part to the presence of antioxidant compounds in fruits and vegetables. As a result, these compounds have been considered together by many people and loosely termed dietary antioxidants. Closer examination, however, reveals that compounds typically grouped together as dietary antioxidants can differ quite considerably from one another, both in terms of their chemical behavior and in terms of their biological properties. This report from the Institute of Medicine's Food and Nutrition Board provides a proposed definition of dietary antioxidants so as to characterize the biological properties of these compounds.

The model for risk assessment of nutrients used to develop tolerable upper intake levels (ULs) is one of the key elements of the developing framework for Dietary Reference Intakes (DRIs). DRIs are dietary reference values for the intake of nutrients and food components by Americans and Canadians. The U.S. National Academy of Sciences recently released two reports in the series (IOM, 1997, 1998). The overall project is a comprehensive effort undertaken by the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes (DRI Committee) of the Food and Nutrition Board (FNB), Institute of Medicine, National Academy of Sciences in the United States, with active involvement of Health Canada. The DRI project is the result of significant discussion from 1991 to 1996 by the FNB regarding how to approach the growing concern that one set of quantitative estimates of recommended intakes, the Recommended Dietary Allowances (RDAs), was scientifically inappropriate to be used as the basis for many of the uses to which it had come to be applied.

Since 1941, Recommended Dietary Allowances (RDAs) has been recognized as the most authoritative source of information on nutrient levels for healthy people. Since publication of the 10th edition in 1989, there has been rising awareness of the impact of nutrition on chronic disease. In light of new research findings and a growing public focus on nutrition and health, the expert panel responsible for formulation RDAs reviewed and expanded its approach--the result: Dietary Reference Intakes. This new series of references greatly extends the scope and application of previous nutrient guidelines. For each nutrient the book presents what is known about how the nutrient functions in the human body, what the best method is to determine its requirements, which factors (caffeine or exercise, for example) may affect how it works, and how the nutrient may be related to chronic disease. The first volume of Dietary Reference Intakes includes calcium, phosphorus, magnesium, vitamin D, and fluoride. The second book in the series presents information about thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, biotin, and choline.Based on analysis of nutrient metabolism in humans and data on intakes in the U.S. population, the committee recommends intakes for each age group--from the first days of life through childhood, sexual maturity, midlife, and the later years. Recommendations for pregnancy and lactation also are made, and the book identifies when intake of a nutrient may be too much. Representing a new paradigm for the nutrition community, Dietary Reference Intakes encompasses: * Estimated Average Requirements (EARs). These are used to set Recommended Dietary Allowances. * Recommended Dietary Allowances (RDAs). Intakes that meet the RDA are likely to meet the nutrient requirement of nearly all individuals in a life-stage and gender group. * Adequate Intakes (AIs). These are used instead of RDAs when an EAR cannot be calculated. Both the RDA and the AI may be used as goals for individual intake. * Tolerable Upper Intake Levels (ULs). Intakes below the UL are unlikely to pose risks of adverse health effects in healthy people. This new framework encompasses both essential nutrients and other food components thought to pay a role in health, such as dietary fiber.It incorporates functional endpoints and examines the relationship between dose and response in determining adequacy and the hazards of excess intake for each nutrient.

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.

Malnutrition and obesity are both common among Americans over age 65. There are also a host of other medical conditions from which older people and other Medicare beneficiaries suffer that could be improved with appropriate nutritional intervention. Despite that, access to a nutrition professional is very limited. * Do nutrition services benefit older people in terms of morbidity, mortality, or quality of life? * Which health professionals are best qualified to provide such services? * What would be the cost to Medicare of such services? Would the cost be offset by reduced illness in this population? This book addresses these questions, provides recommendations for nutrition services for the elderly, and considers how the coverage policy should be approached and practiced. The book discusses the role of nutrition therapy in the management of a number of diseases. It also examines what the elderly receive in the way of nutrition services along the continuum of care settings and addresses the areas of expertise needed by health professionals to provide appropriate nutrition services and therapy.

This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.

Since 1994 the Institute of Medicine's Food and Nutrition Board has been involved in developing an expanded approach to developing dietary reference standards. This approach, the Dietary Reference Intakes (DRIs), provides a set of four nutrient-based reference values designed to replace the Recommended Dietary Allowances (RDAs) in the United States and the Recommended Nutrient Intakes (RNIs) in Canada. These reference values include Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL). To date, several volumes in this series have been published. This new book, Applications in Dietary Assessment, provides guidance to nutrition and health research professionals on the application of the new DRIs. It represents both a "how to" manual and a "why" manual. Specific examples of both appropriate and inappropriate uses of the DRIs in assessing nutrient adequacy of groups and of individuals are provided, along with detailed statistical approaches for the methods described. In addition, a clear distinction is made between assessing individuals and assessing groups as the approaches used are quite different.Applications in Dietary Assessment will be an essential companion to any-or all-of the DRI volumes.

The Food and Nutrition Board of the Institute of Medicine (IOM), part of the National Academies, was asked to evaluate the use of various dietary assessment tools and to make recommendations for the assessment of inadequate or inappropriate dietary patterns. These assessments should accurately identify dietary risk of individuals and thus eligibility for participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). The Committee on Dietary Risk Assessment in the WIC Program was appointed for the 2-year study and directed to develop an interim report which was to include (1) a framework for assessing inadequate diet or inappropriate dietary patterns, (2) a summary of a workshop on methods to assess dietary risk, and (3) the results of literature searches conducted to date.This interim report includes these three components. Building on the approach used in the 1996 IOM report, WIC Nutrition Risk Criteria, the framework proposed by the committee identifies characteristics of dietary assessment tools that can identify dietary patterns or behaviors for which there is scientific evidence of increased nutrition or health risk in either the short or long-term. The proposed framework consists of eight characteristics that a food intake and/or behavior-based tool should have when used to determine eligibility to participate in WIC programs. This interim report also includes authored summaries of the presentations at the workshop, along with the results of literature searches conducted in the initial phase of the study.

This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: * Reviews selected components of food that may influence the bioavailability of these compounds. * Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role.* Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. * Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

The current situation regarding labeling and defining dietary fiber in the United States and many other countries is arbitrary due to its reliance on analytical methods as opposed to an accurate definition that includes its role in health. Without an accurate definition, compounds can be designed or isolated and concentrated using the currently available methods, without necessarily providing beneficial health effects. Other compounds can be developed that are nondigestible and provide beneficial health effects, yet do not meet the current U.S. definition based on analytical methods. For the above reasons, the Food and Nutrition Board, under the oversight of the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes, assembled a Panel on the Definition of Dietary Fiber to develop a proposed definition(s) of dietary fiber. This Panel held three meetings and a workshop.
