The purpose of this study was to test the hypothesis that a preload including dried prunes consumed as a snack before a meal, compared to an isoenergetic and equal weighed bread product preload would: (a) have greater short-term effect on satiety measured by subsequent ad libitum meal intake, (b) induce greater satiety as assessed by visual analogue scales (VAS), and (c) reduce appetite for dessert offered shortly after lunch. Forty-five healthy, normal-weight subjects participated in this randomised within-subject crossover study. Statistical analysis of the results showed that when subjects consumed the preload that included dried prunes, also consumed less amount of dessert and had lower total energy intake at meal. Additionally, subjects' feeling of hunger, desire and motivation to eat, as assessed with the use of VAS, were lower at all time points between snack and meal. Since macronutrients content of both preloads were similar, the satiating power of prunes could be due to their relatively high fiber content. Identifying meal patterns and foods that promote satiety without increasing considerably the overall energy intake is very important. The addition of dried prunes to a snack seems to promote satiety besides providing valuable nutrients.
与等能量等重量的面包产品餐前零食相比，正餐前作为零食食用的干梅会：(a) 对随后的随意进食量产生更大的短期饱腹感影响；(b) 通过视觉模拟量表（VAS）评估产生更大的饱腹感；(c) 减少午餐后不久提供的甜点的食欲。45 名健康、体重正常的受试者参加了这项随机、自身交叉研究。结果的统计分析表明，当受试者食用包含干梅的餐前零食时，在正餐时也会减少甜点的摄入量，并且总能量摄入也较低。此外，受试者在零食和正餐之间的所有时间点，使用 VAS 评估的饥饿感、食欲和进食动机都较低。由于两种餐前零食的宏量营养素含量相似，因此梅干的饱腹感可能是由于其相对较高的纤维含量。确定既能促进饱腹感又不会显著增加总能量摄入的膳食模式和食物非常重要。在零食中添加干梅不仅可以提供有价值的营养，还可以促进饱腹感。
