Previous research has shown that beverages containing soluble fibers can decrease energy intake at the next meal among normal weight participants. Caffeine and green tea catechins have separately been associated with increased satiety. The present study examined the satiating power of a beverage containing soluble fiber as well as a beverage containing the same fiber, caffeine and green tea catechins. These two test beverages were evaluated in comparison to an equal calorie control beverage as well as a no-beverage control condition. All beverage preloads were presented three times for a total of 0.28-0.35MJ and 0-30g fiber. Dependent measures were appetite ratings and calorie intake at a test meal. The no-beverage condition was associated with the highest ratings for hunger and the lowest ratings for fullness when compared to the other three beverage conditions. Of the three beverage conditions, the beverage containing the fiber, green tea catechins, and caffeine created the lowest hunger and the highest fullness ratings. That condition was also associated with the lowest energy intake at the next meal. The present findings indicate that the beverage containing caffeine and green tea catechins in combination with soluble fiber decrease appetite and energy intake relative to a beverage with equal caloric content.
先前的研究表明,在正常体重的参与者中,含有可溶性纤维的饮料可以在下一餐中减少能量摄入。咖啡因和绿茶儿茶素分别与饱腹感增加有关。本研究检测了一种含有可溶性纤维以及相同纤维、咖啡因和绿茶儿茶素的饮料的饱腹感。将这两种测试饮料与同等热量的对照饮料和无饮料对照条件进行了比较。所有饮料预加载物共呈现 0.28-0.35MJ 和 0-30g 纤维三次。依赖措施是食欲评分和测试餐的卡路里摄入量。与其他三种饮料条件相比,无饮料条件与饥饿感最高和饱腹感最低的评分相关。在这三种饮料条件中,含有纤维、绿茶儿茶素和咖啡因的饮料产生的饥饿感最低,饱腹感最高。该条件还与下一餐的最低能量摄入有关。本研究结果表明,含有咖啡因和绿茶儿茶素与可溶性纤维的饮料与含有相同热量的饮料相比,可降低食欲和能量摄入。
