Research points to a benefit of inulin fiber on appetite and weight regulation but results remain mixed. Objectives: To test the impact of 16 g/d of Inulin-type fructans (ITFs) on appetite and food intake in acute settings. Forty college age females received either a fiber drink with 16 g of ITFs in 330 ml water or placebo. On the 8 day of the study, appetite sensations were assessed using visual analogue scale (VAS) along with food intake. Repeated-measures ANOVA were performed comparing VAS ratings during test day. Energy consumption was compared using paired t-tests. Significance was determined at p<0.05. On the 8 day, the fiber group reported lower ratings for hunger, desire to eat, and prospective food consumption with significantly higher ratings for satisfaction and fullness. Subsequently, the fiber group consumed 21% less kcal from food at lunch (453 ± 47 kcal) compared to controls (571 ± 39 kcal) (p<0.05). Consuming 16 g/d of ITFs in the morning for 7 days, and after an overnight fast, curbed appetite sensations and helped reduce food intake during lunch meal. These findings highlight the potential of using ITFs in weight management. Future studies should explore ITFs long term benefits.
研究表明菊粉型果聚糖(ITFs)对食欲和体重调节有益,但结果仍不一致。目的:测试每日16克菊粉型果聚糖(ITFs)在急性情况下对食欲和食物摄入量的影响。40名大学年龄女性分别接受了含有16克ITFs的纤维饮料(溶于330毫升水中)或安慰剂。在研究的第8天,使用视觉模拟量表(VAS)评估食欲感觉并记录食物摄入量。采用重复测量方差分析比较测试日的VAS评分。使用配对t检验比较能量消耗。显著性水平设定为p<0.05。在第8天,纤维组报告饥饿、进食欲望和预期食物摄入量的评分较低,而满意度和饱腹感的评分显著较高。随后,与对照组(571±39千卡)相比,纤维组午餐时从食物中摄入的热量减少了21%(453±47千卡)(p<0.05)。连续7天在早晨摄入16克/天的ITFs,并经过一夜禁食后,可抑制食欲,并有助于减少午餐时的食物摄入量。这些发现凸显了使用ITFs进行体重管理的潜力。未来的研究应探索ITFs的长期益处。
