Increased fiber in the diet has been shown in the past to improve bowel function in elderly outpatients and in long-term care institutions. A randomized placebo-controlled, double-blind study was conducted in a geriatric ward of an acute-care hospital to see if a palatable form of fiber would decrease the incidence of constipation and use of laxatives. In this patient sample, no beneficial effect of fiber supplementation could be found when used up to three weeks.
过去已有研究表明，增加饮食中的纤维含量可改善老年门诊患者以及长期护理机构中老人的肠道功能。在一家急症医院的老年病房进行了一项随机、安慰剂对照、双盲研究，以观察一种可口的纤维形式是否会降低便秘发生率和泻药的使用。在这个患者样本中，使用纤维补充剂长达三周时未发现有益效果。
