Instead of presenting a long list of users and potential users of food composition data in Europe, and an even longer list of the needs that are not yet fulfilled in that field, this paper focuses on one specific user group and their problems - the nutritional epidemiologists. A close look at the difficulties faced by persons conducting international nutritional epidemiology sheds light on many of the European and non European problems in the use of food composition data.
Relevant to the broader context of users and needs of food composition data in Europe is the collection of issues presented at the workshop entitled "Towards Compatibility of Food Nutrient Composition Data Bases in Europe" |22]. At this meeting, held in Wageningen, the Netherlands, EUROFOODS was founded and work committees established to direct their efforts towards solving European food problems in five areas. Responses to a questionnaire circulated in conjunction with this meeting revealed the breadth and depth of food-nutrient data bases in Europe, and their limitations . A recent update on the number of food entries in the systems of various European countries can be found in figure 1.
