Prebiotic-Like Effects of SweetPearl®Maltitol through Changes in Caecal and Fecal Parameters

Prebiotic-like effects of maltitol were investigated supplementing two groups of rats with either 5% maltodextrin (control group) or 5% maltitol (maltitol group). A third group was supplemented with 5% maltitol at first and then with 5% maltodextrin (maltitol/maltodextrin group). Faecal parameters were monitored throughout the experiment and caecal parameters at the end. The weights of caecal content and caecal wall were significantly higher in the maltitol group than in the control group, but not in the maltitol/maltodextrin group. Propionic acid concentration was significantly higher in the maltitol group compared to both control and maltitol/maltodextrin group. Faecal parameters were also influenced by the dietary supplementation with maltitol: the amount of dry matter in feces decreased and alpha-glucosidase activity increased. These effects lasted 28 days in the maltitol only group, whereas they stopped some days after the switch to maltodextrin in the maltitol/maltodextrin group. Maltitol could induce prebiotic-like effects.

NUTRIOSE1^®膳食纤维补充剂对男性超重者的体重，体成分，能量摄入量和饥饿感的影响

目的评估NUTRIOSE水溶性膳食纤维对中国成年男性超重者的体重、体成分、能量摄入量和饥饿感的影响。方法在双盲条件下，将受试者随机分成两组，分别摄入含17gNUTRIOSE锄水溶性膳食纤维（实验组，n=60）和含17g麦芽糊精（对照组，n=60）的果汁250ml，每天2次，为期12周。在试验的第0周，第4周，第8周和第12周测量受试者的体重和体成分，每3天评估1次受试者的日均能量摄入量和饥饿感。结果12周后，实验组受试者平均体重较对照组轻1．5kg（P〈0．001），体质指数平均减少0．5kg／m^2（P〈0．001），身体脂肪率平均降低了0．3％（P〈0．001）。且在试验开始的第3天，NUTRIOSE水溶性膳食纤维组的日均能量摄入量就低于对照组（12周平均日能量摄入量，实验组较对照组低3079kJ／天，P〈0．001）。试验过程中，实验组受试者的饥饿感比对照组受试者的饥饿感小（P〈0．001）。结论NUTRIOSE膳食纤维补充剂有助于男性超重者改善体成分，降低体重和日均能量摄人量，减少饥饿感。
