``````````膳食纤维在防治疾病方面有五大功效： 　
　
第一、食物纤维在肠胃吸收水分膨胀，体积增加，增强饱腹感，可溶性纤维形成了胶态，延缓了葡萄糖和脂肪的吸收。逐渐使血糖和血脂水平下降。从而可以有效防止高血糖、高血脂类疾病的发生。 　
　
第二、缩短食物在胃中停留的时间，一般来说，普通食品需要28小时才能从肠道中排空，而富含食物纤维的食品只需要14-16小时，这样大大减少了对有害物质的吸收。 　　

第三、食物纤维还能吸附和稀释致癌物及有毒物使之排除体外，从而在一定程度上具有防癌的功能。 　　

第四、纤维在肠内酵解，导致肠内PH值下降，影响厌氧菌群代谢活动成为抗肿瘤发生的因子来源。 　　

第五、食物纤维还能促进胆固醇转化为胆酸，减少胆酸通过肝再循环，从而降低胆固醇，因而能抑止胆固醇上升。``````````````````````````
