Protein Energy Requirements Under Conditions Prevailing In Developing Countries

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.

This book contains the proceedings of the Eleventh Annual Basic Symposium sponsored by the Institute of Food Technologists and the International Union of Food Science and Technology. It discusses nutrition interactions in human and emphasizes research findings from human and animal studies.

There are several reasons why a consolidation of recent advances in our understanding of the interaction of diarrhea and malnutrition is indi cated and timely. It is now widely recognized that diarrhea is a major cause of morbidity and mortality among children of poor countries. Due to recent advances in laboratory and field diagnostic techniques, many of the previously unrecognized etiologic agents responsible for diarrhea have been identified, thereby providing new scientific knowledge for rational control strategies. Increasingly these advances suggest that the morbidity burden of diarrhea may be of equal, if not greater, public health consequence than mortality. Diarrhea only rarely causes disease severe enough to require institutionalized medical care. The vast major ity of diseases are of mild or moderate severity, and because of high prev alence, diarrhea imposes an enormous morbidity burden and exerts a sig nificant negative impact on child growth and development. Moreover, the effects of successive episodes of diarrhea are likely to be cumulative. In contrast to several other childhood infections, the treatment of the diarrheal diseases is feasible because it uses simple, effective, and low cost medical technologies. Within the context of these developments, there has been a major resurgence of international interest in, and commitment to, the control of the diarrheal diseases. The World Health Organization recently has launched a global program for the control of diarrhea, and simulta neously, an independent international research center on diarrhea has been established in Bangladesh.

A two-volume set which traces the history of food and nutrition from the beginning of human life on earth through the present.

Genetic Factors in Nutrition presents the proceedings of the International Workshop on Genetic Factors in Nutrition, held in Teotihuacan, Mexico, on August 4-8, 1982. The papers explore the link between genetics and nutrition in the context of biological evolution. They provide examples of successful interaction between the two disciplines and consider some aspects of nutrient requirements, as well as utilization and consideration of methodological approaches to evaluate nutritional status, with an emphasis on malnutrition. Divided into six parts encompassing 29 chapters, this volume begins with an overview of genetics and nutrition from an evolutionary perspective, citing findings among Amerindians. It proceeds with a discussion of the potential application of genetic epidemiology in nutritional research, nutrient requirements and metabolism, the association between obesity and energy balance, and assessment of nutritional status. It also presents case studies of the correlation between genetics and nutrition before introducing the reader to genetic inheritance and growth in human groups suffering from chronic under-nutrition. Some data derived from nutrition longitudinal studies are analyzed to interpret the nutrition-genetics interaction. This book will be a valuable source of information for scientists and students in genetics and nutrition.

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.

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.
