In Israel, the incidence of colorectal cancer is highest in European-American-born Jews, although this incidence is lower than that found in European-born Jews living in the United States. A significantly lower-than-expected incidence was found in a specific kibbutz established by immigrants of European origin. Matched population samples from this kibbutz and the city of Tel Aviv revealed significant differences in dietary habits. The kibbutz members ate more unavailable carbohydrate and ascorbic acid and had a higher dietary polyunsaturated to saturated fat (P/S) ratio than the city dwellers. Both groups ate more crude fiber, less saturated fat, and less beef than has been reported from American and European countries. This kibbutz diet seems to have prevented large bowel cancer, parallels the "prudent" diet of Wynder, and possibly indicates the feasibility of colorectal cancer prevention.
在以色列，欧美裔出生的犹太人患结直肠癌的发病率最高，尽管这一发病率低于生活在美国的欧洲裔出生的犹太人。在一个由欧洲裔移民建立的特定集体农场中，发现发病率显著低于预期。来自这个集体农场和特拉维夫市的匹配人群样本显示，饮食习惯存在显著差异。集体农场成员摄入的不可利用碳水化合物和抗坏血酸更多，饮食中多不饱和脂肪与饱和脂肪的比例（P/S）高于城市居民。与美国和欧洲国家报道的情况相比，两组摄入的膳食纤维都更多，饱和脂肪和牛肉更少。这种集体农场饮食似乎预防了大肠癌，与温德的“谨慎”饮食相似，并且可能表明预防结直肠癌是可行的。
