Résumé : All Belgian dietetic enquiries converge to establish that Dutch-speaking communities use much more dietary margarines with a high P/S ratio than French-speaking ones. Thus, among 4000 railwaymen, 46% of the Dutch-speaking workmen use such a margarine as bread spreading fat and only 28% eat butter, whereas only between 9 and 18.5% of the French-speaking workmen eat dietary margarine, the overwhelming majority of them (between 69% and 77.5%) using butter. These figures result from a dietetic questionnaire and are authenticated by a significantly higher percentage (60.43% ± 0.89 against 53.01% ± 1.05; p< 0.001) of linoleate among the esters of plasma cholesterol of the groups that use dietary margarine compared with butter eaters. All comparative epidemiological studies on cholesterolemia in Belgium equally point out, without any exception, a relative hypercholesterolemia amoung French-speaking in comparison with Dutch-speaking people. Among his groups of railwaymen, the authors finds a mean serum cholesterol 228.65 mg/dl ± 1.31 for the 934 French-speaking men, when their age is adjusted to the Belgian male population, whereas that of the 1152 Dutch-speaking men only rises to 220.65 mg/dl ± 1.18, which is a very significant difference (p<0.001). The author establishes that this difference mainly comes from the unequal degree of saturation of spreading fats more frequently used in each of the linguistic subgroups. Besides, Belgian studies on comparative coronary morbidity are unanimous in pointing out a significantly higher prevalence of the different kinds of ischaemic cardiopathies among French-speaking than among Dutch-speaking people, and this as well in professionally as in socially different strata. Finally, the recent study of U.C.L. demographic department on coronary mortality in the different parts of the country shows a definitely higher mortality in the south. As the prevalence of the factors of coronary risk factors is practically the same in both linguistic groups, only the relative hypercholesterolemia of French-speaking people may explain their higher degree morbidity and mortality. The hyper cholesterolemia of French-speaking communities being connected with an absolute and relative overconsumption of saturated fats, the author asks that the assembly should recommend the dietetic measures advised by F.A.O.: the reduction of lipid calories to 30% of the whole ration, one third of dietary fats being polyunsaturated.
