Résumé : Between September 1998 and February 2000, Belgian general practitioners (GPs) who graduated since 1965 were contacted by mail to participate in an epidemiological study on cardiovascular and behavioural risk factors (the Coronary Heart Disease Monitor or CHD-Monitor). In this article, we present data from the CHD-Monitor related to the consumption of butter on bread slices. In Wallonia 751 persons (35,7%) smear regularly butter on their daily slices of bread, in Flanders 380 (13,4%) and in Brussels 190 (32,7%) (p<0,0001 for the difference between Flanders and Wallonia and for Flanders and Brussels). In Wallonia one third of the patients with a coronary pathology and/or with diabetes mellitus declared using butter on a regular basis, in contrast to Flanders where only 1 per ten persons with the same disease(s) declared himself a consumer. The use of butter decreases with age for men in the Flanders, in contrast to Wallonia. Smokers have a spontaneously increased risk for coronary disease and mortality; moreover, they use as well in Flanders as in Wallonia more frequently than non-smokers butter on their bread slices (more than four out of 10 smokers use butter) (difference between smokers and nonsmokers is significant p<0,001 for Flanders and Wallonia). These data confirm the regional differences in butterconsumption which were demonstrated in the Belgian epidemiologic studies of the sixties and seventies. Considering the content of saturated fatty acids in butter, the regular use of butter does not make it possible to respect the norm for saturated fatty acids.
