This book is intended to be a tool for personnel working in the field of public nutrition or related areas. Such personnel may be public nutritionists, community dieticians, physicians, nurses, mid-level managers and planners and managers in government and private institutions with responsibility for or interested in public nutrition, and relevant others who are not mentioned here. The personnel of non-governmental and international organisations and university departments concerned with health and nutrition may also find it useful. The book may not be considered as a textbook on basic issues in nutrition or research methodology. It is assumed that the people who will use the book already have fundamental skills in these areas. The approach suggested reflects the author’s viewpoint on public nutrition. The editor has drawn for the first publication of the book, and his own experiences, that of other people working in public nutrition, various theories in nutrition and health planning, education, social marketing, business planning and leadership, and managers by objectives. The World Health Organisation should also be thanked for allowing using the second issue of the book, Planning and Managing Community Nutrition Work, as a point of departure for this issue.
