Belgium can be divided in 4 major geographical areas: two Dutch speaking areas in the north (Campine and Flanders), a French speaking area in the south (Wallonia) and the Brussels area in between. Significant differences in mean serum cholesterol levels were observed with the lowest level in Campine, intermediate in Flanders and Brussels, and the highest level in Wallonia. Similar differences were observed in the prevalence of CHD and mortality from CHD is also higher in the French speaking part of the country. A survey of food habits since 1959 shows a higher butter and lower soft margarine consumption in the south. However, differences in smoking habits and personality traits also exist.
