The beneficial effect of wheat fibres on faecal bulk and stool pattern has mainly been observed with intact wheat fibres. This study investigates the effect of extrinsic wheat fibre (VITACEL® wheat fibre), which can be easily incorporated in many food products, on faecal bulk, stool pattern, gastrointestinal complaints, satiety and food liking. In a double-blind randomized crossover trial, healthy male volunteers received meal boxes for 10 days, containing various food products enriched with extrinsic wheat fibre (∼20 grams of additional fibre per day) or control food products containing conventional levels of fibre with similar taste, appearance and caloric values. Meal boxes were integrated in the normal dietary pattern. Stool frequency, stool consistency, gastrointestinal complaints, satiety and product liking were assessed daily, and the last 5 days of each intervention, participants collected all their faeces to analyse faecal bulk. We found that consumption of extrinsic wheat fibre-enriched products significantly enhanced faecal bulk; faecal wet and dry weight showed a 1.41 ± 0.1 and 1.55 ± 0.1 times increase compared to control, respectively (p < 0.01). Extrinsic wheat fibre intervention furthermore increased stool frequency (1.3 ± 0.1 defecations per day compared to 1.1 ± 0.1 defecations per day during control diet, p < 0.05), but did not affect stool consistency, satiety, gastrointestinal complaints or product liking. So, increased consumption of extrinsic wheat fibre enhances faecal bulk and stool frequency. As this extrinsic wheat fibre can be easily incorporated in many food products without affecting appearance or taste, it might facilitate the increase of overall fibre intake and subsequently improve (intestinal) health.

外用小麦纤维的消耗会增加粪便的体积和粪便频率；随机对照试验†
主要在完整的小麦纤维中观察到小麦纤维对粪便体积和粪便模式的有益作用。这项研究调查了外在的影响小麦纤维（VITACEL®小麦纤维），可以很容易地掺入许多食品中，包括粪便体积，粪便形态，胃肠道不适，饱腹感和食物喜好。在一项双盲随机交叉试验中，健康的男性志愿者接受了10天的餐盒，其中装有各种富含外在小麦纤维的食品（每天约20克额外的纤维），或对照食品中含有常规水平的类似口味的纤维，外观和热量值。餐盒按照正常的饮食习惯进行整合。每天评估粪便频率，粪便稠度，胃肠道不适，饱腹感和产品喜好，并且在每次干预的最后5天，参与者收集所有粪便以分析粪便量。我们发现食用外在的富含小麦纤维的产品显着增加了粪便的体积。粪便的干重和湿重分别比对照增加1.41±0.1和1.55±0.1倍（p <0.01）。外源性小麦纤维干预进一步增加了大便频率（与对照饮食相比，每天排便量为1.3±0.1，而每天排便量为1.1±0.1，p <0.05），但并未影响粪便的稠度，饱腹感，胃肠道不适或产品喜好。因此，增加外在小麦纤维的消耗会增加粪便的体积和粪便频率。由于这种外在的小麦纤维可以很容易地掺入许多食品中而不会影响外观或味道，因此它可以促进纤维总摄入量的增加，从而改善（肠道）健康。
