Nutrition has long been considered more the domain of medicine and agriculture than of the biological sciences, yet it touches and shapes all aspects of the natural world. The need for nutrients ...determines whether wild animals thrive, how populations evolve and decline, and how ecological communities are structured.The Nature of Nutritionis the first book to address nutrition's enormously complex role in biology, both at the level of individual organisms and in their broader ecological interactions.
Stephen Simpson and David Raubenheimer provide a comprehensive theoretical approach to the analysis of nutrition--the Geometric Framework. They show how it can help us to understand the links between nutrition and the biology of individual animals, including the physiological mechanisms that determine the nutritional interactions of the animal with its environment, and the consequences of these interactions in terms of health, immune responses, and lifespan. Simpson and Raubenheimer explain how these effects translate into the collective behavior of groups and societies, and in turn influence food webs and the structure of ecosystems. Then they demonstrate how the Geometric Framework can be used to tackle issues in applied nutrition, such as the problem of optimizing diets for livestock and endangered species, and how it can also help to address the epidemic of human obesity and metabolic disease
Drawing on a wealth of examples from slime molds to humans,The Nature of Nutritionhas important applications in ecology, evolution, and physiology, and offers promising solutions for human health, conservation, and agriculture.
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.
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.
An understanding of the mineral nutrition of plants is of fundamental importance in both basic and applied plant sciences. The Third Edition of this book retains the aim of the first in presenting ...the principles of mineral nutrition in the light of current advances. This volume retains the structure of the first edition, being divided into two parts: Nutritional Physiology and Soil-Plant Relationships. In Part I, more emphasis has been placed on root-shoot interactions, stress physiology, water relations, and functions of micronutrients. In view of the worldwide increasing interest in plant-soil interactions, Part II has been considerably altered and extended, particularly on the effects of external and interal factors on root growth and chapter 15 on the root-soil interface. The third edition will be invaluable to both advanced students and researchers.

The Dietary Reference Intakes (DRIs) are quantitative estimates of nutrient intakes to be used for planning and assessing diets for apparently healthy people. This volume is the second of two reports ...in the DRI series aimed at providing specific guidance on the appropriate uses of the DRIs. The first report provided guidance on appropriate methods for using DRIs in dietary assessment. This volume builds on the statistical foundations of the assessment report to provide specific guidance on how to use the appropriate DRIs in planning diets for individuals and for groups.
Dietary planning, whether for an individual or a group, involves developing a diet that is nutritionally adequate without being excessive. The planning goal for individuals is to achieve recommended and adequate nutrient intakes using food-based guides. For group planning, the report presents a new approach based on considering the entire distribution of usual nutrient intakes rather than focusing on the mean intake of the group. The report stresses that dietary planning using the DRIs is a cyclical activity that involves assessment, planning, implementation, and reassessment.
Nutrition and public health researchers, dietitians and nutritionists responsible for the education of the next generation of practitioners, and government professionals involved in the development and implementation of national diet and health assessments, public education efforts and food assistance programs will find this volume indispensable for setting intake goals for individuals and groups.

Humans have become much taller and heavier, and experience healthier and longer lives than ever before in human history. However it is only recently that historians, economists, human biologists and ...demographers have linked the changing size, shape and capability of the human body to economic and demographic change. This fascinating and groundbreaking book presents an accessible introduction to the field of anthropometric history, surveying the causes and consequences of changes in health and mortality, diet and the disease environment in Europe and the United States since 1700. It examines how we define and measure health and nutrition as well as key issues such as whether increased longevity contributes to greater productivity or, instead, imposes burdens on society through the higher costs of healthcare and pensions. The result is a major contribution to economic and social history with important implications for today's developing world and the health trends of the future.
This latest report from the British Nutrition Foundation comprehensively covers the subject of Developmental Programming and Diet. This book covers programming factors involved in the vulnerabilities ...in early development to nutrients and looks in detail at the relationship between nutrition during critical phases of development and disease risk later in life and includes coverage of obesity, diabetes, cardiovascular disease, cancer, bone health and psychiatric health. All nutritionists, dietitians and those working in developmental programming, including physiologists, endocrinologists, epidemiologists and developmental biologists will find a huge wealth of important and thorough information within this new Task Force Report.
