Short-term effects of a snack including dried prunes on energy intake and satiety in normal-weight individuals

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) in...

Description
Summary: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.
