Abstract: The determination of protein and energy needs in developing nations is complicated by insufficient data, degree of social stress, presence of disease and infection, and differences of individuals and population. An attempt is being made, however, to define the necessary allowances for recovery from infection or mild malnutrition and for the maintenance of health. The crucial questions revolve around relative requirements under prevailing conditions, whether there are indeed different requirements for different populations, and whether those requirements can be determined in reference to healthy, will-fed populations. These questions are addressed through information on known protein and energy requirements for health maintenance and tissue repletion, and nutritional consequences of infections. Recommendations are outlined for research priorities.
Abstract: A report of a 1981 workshop by the International Union of Nutritional Sciences Committee on Protein-Energy Requirements reviews the current state of world research findings on protein-energy requirements. The 35 technical papers discuss research studies conducted on a variety of sub-populations and ethnic groups. The papers are organized under 6 principal categories: (1) general methodological studies for assessing human protein-energy requirements; (2) studies assessing adult protein requirements using (a) the standard nitrogen balance protocol, (b) long-term studies, and (c) large sample populations; (3) energy expenditure studies; (4) studies on protein-energy interactions; (5) nitrogen balance studies in children; and (6) ancillary studies concerning miscellaneous aspects that influence protein-energy requirements. Two expert reports are appended: (1) a 1977 FAO/WHO report on energy intake and protein requirements, and (2) a 1980 report reviewing collaborative research on protein requirements and energy intake.
This book attempts to bridge the two extreme ends of protein science: on one end, systems proteomics, which describes, at a system level, the intricate connection network that proteins form in a cell, and on the other end, protein chemistry and biophysics, which describe the molecular properties of individual proteins and the structural and thermodynamic basis of their interactions within the network. Bridging the two ends of the spectrum is bioinformatics and computational chemistry. Large data sets created by systems proteomics need to be mined for meaningful information, methods need to be designed and implemented to improve experimental designs, extract signal over noise, and reject artifacts, and predictive methods need to be worked out and put to the test.
A two-volume set which traces the history of food and nutrition from the beginning of human life on earth through the present.
"The purpose of this volume is to examine and explicate both the concept and the quantification of the parameter 'effectiveness' considered indispensable for the evaluation of the increasing typology of operations whose success cannot be measured by profit. Eight papers and the discussions thereof are included."--BOOK JACKET.
The Role of Food, Agriculture, Forestry and Fisheries in Human Nutrition is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Human health and wellbeing depend strongly on production, quality, and availability of food. Agriculture, or cultivation of the soil, harvesting crops, and raising livestock, which are the main sources of food, has no single origin. At different times and in numerous places, many plants and animals have been domesticated to provide food for humankind. Fishing, like farming, is a form of primary food production. Through food gathering, primitive humans first obtained fish and other aquatic products in the shallow waters of lakes and along the seashore, in areas with ebb tides, and in small streams. The breadth and complexity of the subject matter presented here is vast. This volume traces the extraordinary history of human colonization of the habitable world and is a chronicle of humankind’s early communion with the underlying realities of the earth’s physical environment, the eventual destruction of this harmonious relationship, and efforts to repair the damage. To make it easier for the reader the volume is divided into 7 sections Food and agriculture and the use of natural resources examines the relationship between food production and the resource base and demonstrate how humans have adapted and exploited Nature to feed the burgeoning populations of humans and their domestic animals. History of forestry from ancient times to the present day is analyzed and shows the linkage between forest clearance for agriculture and the rise of human populations, and current global environmental issues. History of Fishing is a saga explained that spans the full range from traditional fishing for subsistence through to the evolution of modern factory fishing fleets Impact of global change on agriculture outlines the impact of climate change, human demographic trends and the sustainability issues that arise. Economics and policy of food production analyzes the global trade in foodstuffs and the regional specializations and land use complexities. Fundamentals of human health and nutrition explains the complexities of providing a balanced and safe diet for humans throughout their life cycle from birth to old age. It explores some of the linkages between human health and the quality and quantity of food provided. Human nutrition: an overview provides, a wide ranging summary of the issues and imperatives associated with providing humans with food of a quality and standard that will ensure healthy lives. In the history of human development from the time of the earliest agricultural activities humans have cleared the natural forests and woodlands to obtain building materials and fuel wood, and to provide lands for domestic animals and crops. It is this aspect that is the main focus of the volume. The authors in this volume have analyzed and reviewed the interactions between the utilization of natural resources and human nutrition. Much attention focuses on the specific contribution by agriculture (including livestock husbandry), forestry and fisheries in meeting human needs. This synoptic overview assesses the pattern of past change in the relationship between humans and the resource base on which their lives depend. Lessons learned, or still to be learned, are teased out and elaborated. The vast breadth of the subject matter covered in this volume has meant that the work has benefited from the input of many individual contributors from vastly different parts of the globe. I am grateful to the contributors and reviewers for their time and effort and the exchange of ideas and the learning experience that I obtained by working with such a diverse and learned group. We all owe a debt of gratitude to the vast "invisible college" of colleagues whose publications that have shed light on some of the most pertinent problems facing humankind today. These four volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
This volume provides a contemporary and historical overview of infant nutrition in Europe, North America, and the Third World. It emphasizes the important role that good nutrition, appropriate health care, and a caring environment play in promoting healthy physical and social growth in children. Issues covered include breast feeding, maternal undernutrition and reproductive performance, weaning, and the social and pyschological factors of breast feeding. The book will serve as an excellent guide for nutritionists, pediatricians, health professionals and others involved in child welfare worldwide.
New Protein Foods, Volume 4: Animal Protein Supplies, Part B covers the realities of the world food problems, with special emphasis on protein supply. The book discusses the upper limits of livestock production; the government policy and the production of animal protein; and the nutritional and metabolic impact of variable protein intake in human. The text also describes the developments in pork production; issues in poultry production; as well as the use of small ruminants as food producers. The role of lysine and methionine fortification in animal and human nutrition is also considered. The book further tackles the use of microorganisms as feed and food protein; noncompetitive sources of carbohydrates for animal feeding; and recycling of animal wastes by feeding. The text concludes by discussing issues of affluent society malnutrition as the counterpart to the problems of scarcity. Nutritionists, agriculturists, economists, and people involved in public health and animal research will find the book invaluable.
