BACKGROUND/AIMS: Dietary fibers are frequently included in diets to decrease body weight, but their scarce palatability and the occurrence of meteorism prevent a long-term intake. The aim of this study was to test a mixture of dietary fibers expressly chosen to decrease their negative properties and strengthen their positive effects.
In a series of 10 patients with a slight overweight, the effectiveness of a palatable dietary fibers mixture on gastric emptying and intestinal transit was tested with scintigraphic methods. Then, the effects on body weight and digestive sensations and characteristics of defecations, were evaluated for 4 weeks.
The intestinal transit was significantly shortened by the fiber intake, while the gastric emptying was delayed, but not significantly. The body mass index significantly and progressively decreased, whereas the sense of satiation significantly increased. No effect on abdominal bloating was referred, whereas a significant increase in number of defecations with stools of normal consistency was observed. The acceptability of the fiber mixture was good.
The present research demonstrated that it is possible to prepare a palatable mixture of dietary fibers that maintains the property of decreasing body weight, favors the sense of satiation and accelerates the intestinal transit, with normalization of the stool consistency without the occurrence of meteorism.
背景/目的：膳食纤维常被添加到饮食中以减轻体重，但其适口性差以及会导致腹胀，这使得无法长期摄入。本研究的目的是测试一种特意挑选的膳食纤维混合物，以减少其负面特性并增强其积极效果。
对10名轻度超重患者，用闪烁扫描法测试了一种适口性膳食纤维混合物对胃排空和肠道传输的有效性。然后，评估了其对体重、消化感觉及排便特征的影响，为期4周。
摄入纤维后肠道传输显著缩短，胃排空延迟，但不显著。体重指数显著且逐渐下降，饱腹感显著增加。未提及对腹胀有影响，而观察到正常质地粪便的排便次数显著增加。纤维混合物的可接受性良好。
本研究表明，可以制备一种适口性膳食纤维混合物，其能保持减轻体重的特性，有助于产生饱腹感并加速肠道传输，使粪便质地正常化且不出现腹胀。
