Strategies to increase fruit and vegetable consumption of preschool aged children are needed.
Evaluate the independent effects of the following meal service strategies on intake of fruits and vegetables of preschool children: 1.) Serving fruits and vegetables in advance of other menu items as part of traditional family style meal service; and 2.) Serving meals portioned and plated by providers.
Fifty-three preschool aged children completed a randomized crossover experiment conducted at a Head Start center in Minneapolis, MN. Over a six week trial period each of the experimental meal service strategies (serving fruits and vegetable first and serving meals portioned by providers) was implemented during lunch service for two one-week periods. Two one-week control periods (traditional family style meal service with all menu items served at once) were also included over the six week trial period. Childrens lunch intake was observed as a measure of food and nutrient intake during each experimental condition.
Fruit intake was significantly higher (p<0.01) when fruits and vegetables were served in advance of other meal items (0.40 servings/meal) compared to the traditional family style meal service control condition when they were served in tandem with other menu items (0.32 servings/meal). Intakes of some nutrients found in fruits (vitamin A and folate) were concomitantly higher. In contrast, fruit and vegetable intakes were significantly lower and energy intake significantly higher during the provider portioned compared with control condition.
Serving fruits in advance of other meal items may be a low cost easy to implement strategy for increasing fruit intake in young children. However, serving vegetables first does not appear to increase vegetable intake. Results provide support for current recommendations for traditional family style meal service in preschool settings.
需要制定增加学龄前儿童水果和蔬菜摄入量的策略。
评估以下餐饮服务策略对学龄前儿童水果和蔬菜摄入量的独立影响:1. 将水果和蔬菜提前供应,作为传统家庭式餐饮服务的一部分;2. 由服务人员分餐和装盘。
53 名学龄前儿童在明尼苏达州明尼阿波利斯市的一家“Head Start 中心”完成了一项随机交叉实验。在为期六周的试验期间,每种实验餐饮服务策略(先供应水果和蔬菜,以及由服务人员分餐)在午餐服务期间实施两周。在六周的试验期间还包括两个为期一周的对照期(所有餐食一次性供应的传统家庭式餐饮服务)。在每个实验条件下,观察儿童的午餐摄入量,以衡量食物和营养摄入量。
当水果和蔬菜先于其他餐食供应时(每餐 0.40 份),水果摄入量显著更高(p<0.01),与传统家庭式餐饮服务对照条件(同时供应其他餐食时每餐 0.32 份)相比。一些在水果中发现的营养素(维生素 A 和叶酸)的摄入量也随之增加。相比之下,在提供者分餐时,水果和蔬菜的摄入量显著降低,能量摄入量显著增加。
将水果提前供应其他餐食可能是一种低成本、易于实施的策略,可增加幼儿的水果摄入量。然而,先供应蔬菜似乎不会增加蔬菜摄入量。结果为当前在学前环境中推荐的传统家庭式餐饮服务提供了支持。
