Twenty original papers that reported on the effect of wheat bran on large bowel function were analysed. Bran increased the stool weight and decreased the transit time in each study in healthy controls and in patients with the irritable bowel syndrome, with diverticula, and with chronic constipation. Statistical evaluation of the data showed, however, that constipated patients had lower stool output and slower transit whether or not they had taken bran, and they responded less well to bran treatment than controls. From these data it is concluded that bran can be expected to be only partially effective in restoring normal stool weight and transit time in patients who are constipated.
分析了20篇报道麦麸对大肠功能影响的原创论文。在每项研究中,无论是健康对照者,还是患有肠易激综合征、憩室病和慢性便秘的患者,麦麸均增加了粪便重量并缩短了转运时间。然而,数据的统计评估显示,便秘患者无论是否食用麦麸,其粪便排出量均较低且转运较慢,并且他们对麦麸治疗的反应不如对照组。从这些数据得出的结论是,对于便秘患者,预计麦麸在恢复正常粪便重量和转运时间方面仅具有部分疗效。
