The therapeutic value of increasing the daily dietary fibre intake was assessed over 3 months in a double-blind controlled trial of 18 patients. Significantly greater symptomatic relief was obtained by those on a high fibre regimen than by those in the control group, despite a marked initial placebo effect. The effectiveness of a high-fibre diet increased over the 3-month period.
在一项针对18名患者的双盲对照试验中,对增加每日膳食纤维摄入量的治疗价值进行了为期3个月的评估。尽管最初有明显的安慰剂效应,但高纤维饮食方案组的患者比对照组的患者获得了显著更大程度的症状缓解。高纤维饮食的有效性在3个月期间有所提高。
