World Health Organization Regional Office for Europe CopenhagenVJ Food and health data Their use in nutrition policy -making rf BANANAS 0 Ai WHO Regional Publications, European Series, No. 34 The World Health Organization is a specialized agency of the United Nations with primary responsibility for international health matters and public health. Through this Organization, which was created in 1948, the health professions of some 165 countries exchange their knowledge and experience with the aim of making possible the attainment by all citizens of the world by the year 2000 of a level of health that will permit them to lead a socially and economically productive life. The WHO Regional Office for Europe is one of six regional offices throughout the world, each with its own programme geared to the particular health problems of the countries it serves. The European Region has 31 active Member States,' and is unique in that a large proportion of them are industri- alized countries with highly advanced medical services. The European pro- gramme therefore differs from those of other regions in concentrating on the problems associated with industrial society. In its strategy for attaining the goal of "health for all by the year 2000" the Regional Office is arranging its activities in three main areas: promotion of lifestyles conducive to health; reduction of preventable conditions; and provision of care that is adequate, accessible and acceptable to all. The Region is also characterized by the large number of languages spoken by its peoples and the resulting difficulties in disseminating information to all who may need it. The Regional Office publishes in four languages- English, French, German and Russian - and applications for rights of translation into other languages are most welcome. a Albania, Austria, Belgium, Bulgaria, Czechoslovakia, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Israel, Italy, Luxembourg, Malta, Monaco,Netherlands,Norway,Poland,Portugal,Romania,SanMarino, Spain, Sweden, Switzerland, Turkey, USSR, United Kingdom and Yugoslavia.

At the same time, the concept of health has been widened, first from solely curative health care to include preventive activities for both individuals and populations, and then to embrace the promotion of health.This in turn has broadened the range of sectors concerned with health.Makers of policies on topics as diverse as city planning and agriculture, for example, must now put health on their political agendas. In this situation,itis not surprising that food and nutrition policies should draw the attention of health planners. Six European countries have made parliamentary decisions to have food and nu- trition policies: Norway in 1975, Denmark and the Netherlands in 1984, Finland in 1985, Malta in 1988 and Iceland in 1989. Several countries may be on the verge of adopting such a policy; Hungary, Poland and Sweden have laid much of the groundwork. The establishment of a food and nutrition policy usually requires the formulation of objectives for desirable changes in the diet of the population.This in turn presupposes that clear and accurate pic- tures can be drawn of the population's dietary pattern and diet - related health (or disease) pattern.These are needed to indicate where changes ought to take place. Data on the dietary patterns of populations can be obtained from several sources. Food balance sheets, household budget surveys and individual -level studies, as well as mortality statistics, are widely available, although the quality of the information they give is seldom assessed. The present volume is intended to fill this gap, to provide a critical assessment of data sources, so that food and nutrition policy -makers may use them with greater confidence. A 1988 publication, Healthy nutrition: preventing nutrition - related diseases in Europe (WHO Regional Publications, European ix Series, No. 24), described the importanceofnutrition policy -making. Taking the next step, the present volume is intended to
