Proportions of "lower" 16:1 and 18:1 trans acids (TL) and "higher" C20 and C22 trans acids (TH) in samples of depot fat taken at postmortem examination from 136 people who had died of ischaemic heart disease (cases) and from those who had died of unrelated causes (controls) have been determined. Whereas mean percentages of TH are virtually identical for cases and controls, the mean value of TL was significantly higher for the case specimens. Although these lower trans acids are present in small amounts in ruminant-animal fat, they are more characteristic of commercially hydrogenated fats. We conclude, therefore, that the cases consumed on average a higher proportion of those hydrogenated fats rich in 16:1 trans and 18:1 trans acids and a lower proportion of ruminant fat than did the controls.
对136名死于缺血性心脏病的人（病例组）和死于非相关病因的人（对照组）进行尸检时采集的储存脂肪样本中，“低”16:1和18:1反式酸（TL）以及“高”C20和C22反式酸（TH）的比例进行了测定。病例组和对照组的TH平均百分比实际上相同，但病例组样本的TL平均值显著更高。尽管这些低反式酸在反刍动物脂肪中含量较少，但它们更具商业氢化脂肪的特征。因此，我们得出结论，与对照组相比，病例组平均食用了更高比例富含16:1反式酸和18:1反式酸的氢化脂肪，而反刍动物脂肪的比例较低。
