The incidence of colorectal cancer in Israel is highest in European- and American-born immigrants. This is believed to be related mainly to their dietary habits. To investigate this issue further, we compared the diets of a sample of members of a well-established kibbutz (BA), which was settled by immigrants of European origin, with the diets of an age- and sex-matched sample of European-born residents of Tel-Aviv and of a previously studied kibbutz (GB). The diet of the people of kibbutz BA compared with those in Tel-Aviv was significantly lower in poultry and significantly higher in polyunsaturated fats; it also had a higher polyunsaturated/saturated fats ratio. Compared with both the Tel-Aviv residents and the kibbutz GB members, the kibbutz BA members had a significantly lower intake of saturated fats; they also had a higher intake of dietary fiber, available carbohydrates, calories, and many minerals and vitamins. However, the incidence of colorectal cancers in the kibbutz BA population was slightly, but non-significantly, higher than expected, based on age, ethnic group, sex, and calendar year-specific national incidence rates. These results are in contrast to our earlier study in which we found that kibbutz GB had less colorectal cancer than expected; thus, the results of the current study are presently unexplained.
在以色列，结直肠癌发病率在欧洲和美国出生的移民中最高。这主要被认为与他们的饮食习惯有关。为了进一步研究这个问题，我们将一个历史悠久的基布兹（BA）的成员样本的饮食与特拉维夫欧洲出生居民的年龄和性别匹配样本以及之前研究过的一个基布兹（GB）的饮食进行了比较。基布兹BA人群的饮食与特拉维夫人群相比，家禽摄入量显著较低，多不饱和脂肪含量显著较高；其多不饱和/饱和脂肪比例也更高。与特拉维夫居民和基布兹GB成员相比，基布兹BA成员的饱和脂肪摄入量显著较低；他们膳食纤维、可利用碳水化合物、卡路里以及多种矿物质和维生素的摄入量也更高。然而，基于年龄、种族、性别和特定日历年的全国发病率，基布兹BA人群的结直肠癌发病率略高于预期，但差异不显著。这些结果与我们早期的研究结果相反，在早期研究中我们发现基布兹GB的结直肠癌发病率低于预期；因此，目前这项研究的结果尚无法解释。
