In samples of adult men from two Scandinavian populations with 4-fold differences in colon cancer incidence, a comparison was made of estimated food records over 4 days, defecation habits, mouth-to-anus transit time, and stool weight. The "high incidence" group consumed more white wheat breads and total meat and beer, but less potatoes and milk than the "low incidence" group. Defecation habits were similar. Transit time and stool weight had few significant correlations with diet and defecation habits, but stool weights were higher in the low incidence group. The results are consistent with a possible protective role of dietary fiber, unrelated to transit time.
在来自两个斯堪的纳维亚人群的成年男性样本中，这两个人群的结肠癌发病率相差4倍，研究人员对他们4天的估计食物记录、排便习惯、口腔到肛门的传输时间和粪便重量进行了比较。“高发病率”组比“低发病率”组摄入更多的白面包、肉类和啤酒，但土豆和牛奶的摄入量较少。排便习惯相似。传输时间和粪便重量与饮食和排便习惯几乎没有显著相关性，但低发病率组的粪便重量更高。结果表明膳食纤维可能具有保护作用，且与传输时间无关。
