No Thumbnail AvailableBook (stand-alone)European Inland Fisheries Advisory Commission Report of the EIFAC Workshop on Methodology for Determination of Nutrient Requirements in Fish. 1994
Also available in:
No results found.The European Inland Fisheries Advisory Commission (EIFAC) organized a Workshop on methodology for determination of nutrient requirements in fish from 29 June to 1 July 1993 in Eichenau, Germany. There were nine consecutive technical sessions during which the various topics were introduced and discussed. These topics referred to energy, proteins and amino acids, digestion and utilization of protein and energy, lipids and essential fatty acids, carbohydrates, minerals and trace elements, vitami ns, feed additives, and application of nutrient requirement data. A series of recommendations were made concerning each of these main topics and are presented in the report together with the abstracts of the papers and posters presented during the Workshop. -
Book (stand-alone)Human energy requirements
Report of a Joint FAO/WHO/UNU Expert Consultation
2004Also available in:
No results found.Since 1949, FAO has convened groups of experts to evaluate current scientific knowledge in order to define the energy requirements of humans and propose dietary energy recommendations for populations. The World Health Organization (WHO) joined this initiative in the early 1950s, and the United Nations University (UNU) in 1981. New scientific knowledge generated in the 20 years since the last consultation was held prompted the assembly of a new expert consultation to make recommen dations for energy requirements of populations throughout the life cycle. This publication is the report of that consultation, which took place from 17 to 24 October 2001 at FAO headquarters in Rome. The report is not meant merely to describe the energy expenditure and requirements of population groups. It is intended also to be prescriptive in supporting and maintaining health and good nutrition, defining human energy requirements and proposing dietary energy recommendations for populations. The new concepts and recommendations set forth in the report include: calculation of energy requirements for all ages; modification of the requirements and dietary energy recommendations for infants, older children and adolescents; proposals for different requirements for populations with lifestyles that involve different levels of habitual physical activity; reassessment of energy requirements for adults, based on energy expenditure estimates expressed as multiples of basal metabolic rates; classification and recommendations of physical activity levels; an experimental approach for factorial estimates of the energy needs of pregnancy and lactation; and recommendations for additional dietary energy needs in the two last trimesters of pregnancy. The report is accompanied by a CD-ROM software program and instruction manual on calculating population energy requirements and food needs. -
DocumentHuman Energy Requirements. A Manual for Planners and Nutritionists 1990
Also available in:
No results found.This manual presents a practical approach to calculating population energy needs. It is intended for use by economists, planners, and nutritionists in all parts of the world, who are dealing with problems of food supply at a national or regional level. An extensive collection of recent data on basal metabolic rates and energy expenditure of different population groups allows estimates of national energy needs to be derived. These figures allow for desirable changes in body weight and height, and physical activity in children and adults. During the preparation of the manual, discussions with planners allowed refinements to be made to suit their needs, especially in the development of computer modelling techniques. Assumptions are made that the reader is not fully versed in nutrition, nor in the finer physiological aspects of energy balance. The manual does highlight the numerous assumptions that are usually made when the energy needs of a population are calculated. It includes data for applying the methodology should local data not be available. A spreadsheet program and a User Guide are included to facilitate the calculation of requirements. As with the manual, data is supplied if local data is not available.
