Snacks are an important part of children's dietary intake, but the role of dried fruit on energy intake in children is unknown. Therefore, the effect of ad libitum consumption of an after-school snack of raisins, grapes, potato chips, and chocolate chip cookies on appetite and energy intake in twenty-six 8- to 11-y-old normal-weight (15th to 85th percentile) children was examined. On 4 separate weekdays, 1 wk apart, children (11 M, 15 F) were given a standardized breakfast, morning snack (apple), and a standardized lunch. After school, children randomly received 1 of 4 ad libitum snacks and were instructed to eat until "comfortably full." Appetite was measured before and 15, 30, and 45 min after snack consumption. Children consumed the least calories from raisins and grapes and the most from cookies (P < 0.001). However, weight of raisins consumed was similar to potato chips (about 75 g) and lower compared to grapes and cookies (P < 0.009). Raisins and grapes led to lower cumulative food intake (breakfast + morning snack + lunch + after-school snack) (P < 0.001), while the cookies increased cumulative food intake (P < 0.001) compared to the other snacks. Grapes lowered appetite compared to all other snacks (P < 0.001) when expressed as a change in appetite per kilocalorie of the snack. Ad libitum consumption of raisins has potential as an after-school snack to achieve low snack intake prior to dinner, similar to grapes, compared to potato chips, and cookies in children 8 to 11 y old.
零食是儿童饮食摄入的重要组成部分,但干水果对儿童能量摄入的影响尚不清楚。因此,研究了 26 名 8 至 11 岁正常体重(第 15 至 85 百分位)儿童随意食用葡萄干、葡萄、薯片和巧克力曲奇饼干作为课后零食对食欲和能量摄入的影响。在 4 个不同的工作日,间隔 1 周,儿童(男 11 人,女 15 人)接受标准化早餐、上午零食(苹果)和标准化午餐。放学后,儿童随机接受 4 种随意食用零食中的 1 种,并被指示吃到“舒适饱”。在零食消费前和 15、30 和 45 分钟后测量食欲。儿童从葡萄干和葡萄中摄入的卡路里最少,从饼干中摄入的卡路里最多(P<0.001)。然而,葡萄干的摄入量与薯片相似(约 75 克),低于葡萄和饼干(P<0.009)。葡萄干和葡萄导致早餐+上午零食+午餐+课后零食的总食物摄入量较低(P<0.001),而饼干与其他零食相比增加了总食物摄入量(P<0.001)。与其他零食相比,葡萄降低了对所有其他零食的食欲(P<0.001),表示为零食每卡路里的食欲变化。与薯片和饼干相比,随意食用葡萄干可能成为儿童 8 至 11 岁的课后零食,可在晚餐前达到低零食摄入量,类似于葡萄。
