Nutritional Requirements of Man: A Conspectus of ResearchAbstract: Information on the human requirements for specific nutrients has been brought together from thousands of international sources, both in current research and historical literature. Clinical researchers, nutrition educators and postgraduate and undergraduate students will find reviews of studies on the needs of healthy people of all ages for protein, amino acids, vitamins A and C, calcium, zinc, iron, copper and folacin. The status of research on these nutrients can be readily ascertained and used to provide a basis for further investigation or for teaching. Each chapter begins with a general introduction and a review of early studies. Some of the topics included are maintenance requirements, factors that influence nutrient status, needs of specific groups, nutrient reserves and absorption, supplementation, and environmental factors. Comments or conclusions for each section provide a synthesis of current knowledge and identify the needs for further research. |
