Book Description
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.

Book Description
Responding to the expansion of scientific knowledge about the roles of nutrients in human health, the Institute of Medicine has developed a new approach to establish Recommended Dietary Allowances (RDAs) and other nutrient reference values. The new title for these values Dietary Reference Intakes (DRIs), is the inclusive name being given to this new approach. These are quantitative estimates of nutrient intakes applicable to healthy individuals in the United States and Canada. This new book is part of a series of books presenting dietary reference values for the intakes of nutrients. It establishes recommendations for energy, carbohydrate, fiber, fat, fatty acids, cholesterol, protein, and amino acids. This book presents new approaches and findings which include the following: The establishment of Estimated Energy Requirements at four levels of energy expenditure Recommendations for levels of physical activity to decrease risk of chronic disease The establishment of RDAs for dietary carbohydrate and protein The development of the definitions of Dietary Fiber, Functional Fiber, and Total Fiber The establishment of Adequate Intakes (AI) for Total Fiber The establishment of AIs for linolenic and a-linolenic acids Acceptable Macronutrient Distribution Ranges as a percent of energy intake for fat, carbohydrate, linolenic and a-linolenic acids, and protein Research recommendations for information needed to advance understanding of macronutrient requirements and the adverse effects associated with intake of higher amounts Also detailed are recommendations for both physical activity and energy expenditure to maintain health and decrease the risk of disease.

Book Description
As essential nutrients, sodium and potassium contribute to the fundamentals of physiology and pathology of human health and disease. In clinical settings, these are two important blood electrolytes, are frequently measured and influence care decisions. Yet, blood electrolyte concentrations are usually not influenced by dietary intake, as kidney and hormone systems carefully regulate blood values. Over the years, increasing evidence suggests that sodium and potassium intake patterns of children and adults influence long-term population health mostly through complex relationships among dietary intake, blood pressure and cardiovascular health. The public health importance of understanding these relationships, based upon the best available evidence and establishing recommendations to support the development of population clinical practice guidelines and medical care of patients is clear. This report reviews evidence on the relationship between sodium and potassium intakes and indicators of adequacy, toxicity, and chronic disease. It updates the Dietary Reference Intakes (DRIs) using an expanded DRI model that includes consideration of chronic disease endpoints, and outlines research gaps to address the uncertainties identified in the process of deriving the reference values and evaluating public health implications.

Book Description
Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate The Dietary Reference Intakes (DRIs) are quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. This new report, the sixth in a series of reports presenting dietary reference values for the intakes of nutrients by Americans and Canadians, establishes nutrient recommendations on water, potassium, and salt for health maintenance and the reduction of chronic disease risk. Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate discusses in detail the role of water, potassium, salt, chloride, and sulfate in human physiology and health. The major findings in this book include the establishment of Adequate Intakes for total water (drinking water, beverages, and food), potassium, sodium, and chloride and the establishment of Tolerable Upper Intake levels for sodium and chloride. The book makes research recommendations for information needed to advance the understanding of human requirements for water and electrolytes, as well as adverse effects associated with the intake of excessive amounts of water, sodium, chloride, potassium, and sulfate. This book will be an invaluable reference for nutritionists, nutrition researchers, and food manufacturers.

Book Description
Ensuring that the food provided to children in schools is consistent with current dietary recommendations is an important national focus. Various laws and regulations govern the operation of school meal programs. In 1995, Nutrition Standards and Meal Requirements were put in place to ensure that all meals offered would be high in nutritional quality. School Meals reviews and provides recommendations to update the nutrition standard and the meal requirements for the National School Breakfast and Lunch Programs. The recommendations reflect new developments in nutrition science, increase the availability of key food groups in the school meal programs, and allow these programs to better meet the nutritional needs of children, foster healthy eating habits, and safeguard children's health. School Meals sets standards for menu planning that focus on food groups, calories, saturated fat, and sodium and that incorporate Dietary Guidelines for Americans and the Dietary Reference Intakes. This book will be used as a guide for school food authorities, food producers, policy leaders, state/local governments, and parents.

Book Description
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 approachâ€"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 groupâ€"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.

Book Description
The National School Breakfast Program feeds 10 million children each day, and the National School Lunch Program feeds more than 30 million students. Yet the national nutrition standards and meal requirements for these meals were created more than a decade ago, making them out of step with recent guidance about children's diets. With so many children receiving as much as 50 percent of their daily caloric intake from school meals, it is vital for schools to provide nutritious food alongside the best possible education for the success of their students. At the request of U.S. Department of Agriculture (USDA), the Institute of Medicine assembled a committee to recommend updates and revisions to the school lunch and breakfast programs. The first part of the committee's work is reflected in the December 2008 IOM report Nutrition Standards and Meal Requirements for National School Lunch and Breakfast Programs: Phase I. Proposed Approach for Recommending Revisions. Phase II of the report is expected in Fall 2009. This first report provides information about the committee's approach as it reviews the school lunch and breakfast programs. In the report's second part, the committee will share its findings and recommendations to bring these meals more in line with today's dietary guidelines. The committee welcomes public comments about its intended approach. An open forum will be held January 28, 2009 in Washington, DC to receive input from the public.

Book Description
The Child and Adult Care Food Program (CACFP) is a federally-funded program designed to provide healthy meals and snacks to children and adults while receiving day care at participating family day care homes, traditional child care centers, afterschool facilities, adult care facilities, and emergency shelters. CACFP has the broadest scope of any of the U.S. Department of Agriculture (USDA) food program, serving more than 3 million children and 114,000 adults across the nation. To receive reimbursement for the foods served, participating programs must abide by requirements set by the USDA. Child and Adult Care Food Program assesses the nutritional needs of the CACFP population based on Dietary Guidelines for Americans and the Dietary Reference Intakes (DRIs) and makes recommendations for revisions to the CACFP meal requirements. The book outlines meal requirements that include food specifications that could be used for specific meals and across a full day, covering all age groups from infants to older adults and meal patterns designed for use in a variety of settings, including in-home care and in large centers. By implementing these meal requirements, consumption of fruits, vegetables, and whole-grain rich foods will increase while consumption of solid fats, added sugars, and sodium will decrease. Not only will this address the high prevalence of childhood obesity, it will also help to achieve consistency with the standards and regulations of other USDA nutrition assistance programs, particularly the Supplemental Nutrition Program for Women, Infants, and Children (WIC), and the National School Lunch and School Breakfast programs. Child and Adult Care Food Program makes practical recommendations that would bring CACFP meals and snacks into alignment with current dietary guidance. The book will serve as a vital resource for federal and state public health officials, care providers working in child and adult day care facilities, WIC agencies, officials working with the National School Lunch and School Breakfast programs, and other organizations serving at-risk populations.

Book Description
In the past 20 years micronutrients have assumed great public health importance and a considerable amount of research has lead to increasing knowledge of their physiological role. Because it is a rapidly developing field, the WHO and FAO convened an Expert Consultation to evaluate the current state of knowledge. It had three main tasks: to review the full scope of vitamin and minerals requirements; to draft and adopt a report which would provide recommended nutrient intakes for vitamins A, C, D, E, and K; the B vitamins; calcium; iron; magnesium; zinc; selenium; and iodine; to identify key issues for future research and make preliminary recommendations for the handbook. This report contains the outcome of the Consultation, combined with up-to-date evidence that has since become available.
