Schools often offer healthy fruits and vegetables (FV) and healthy entrées. However, children may resist these efforts due to a lack of familiarity with the offerings. While numerous exposures with a food increase its liking, it may be that an exposure to a variety of FV at home leads to greater willingness to select other foods - even those that are unrelated to those eaten at home. As an initial test of this possibility, this study was designed to examine how self-reports of exposure and consumption of various FV were associated with the selection of FV and lunch entrées at school. Participants (n = 59) were a convenience sample of elementary children. A median split was used to place students into high- and low-exposure groups for self-reports of both exposure and consumption at home. The primary dependent variables were self-reports of selecting FV at school; the children's absolute and relative ratings of eight 'healthier' lunch entrées; and self-reports of selecting these entrées. These entrées were recently added to the school menu and, therefore, tended to be less familiar to children. Food ratings were collected through taste exposures conducted at school. Results indicate that children who reported more frequent exposure to FV at home consumed a wider variety of FV at school and were more likely to report selecting 'healthier' entrées at school lunch. These data suggest that exposure to, and the consumption of, a variety of FV may make children more willing to select a wider range of FV and other healthy entrées.
学校通常会提供健康的水果和蔬菜(FV)以及健康的主菜。然而,由于孩子们对这些食物不太熟悉,他们可能会抵制这些举措。虽然多次接触某种食物会增加对它的喜爱,但在家中接触各种FV可能会使孩子们更愿意选择其他食物——甚至是那些与在家中吃的食物无关的食物。作为对这种可能性的初步测试,本研究旨在考察各种FV的接触和消费自我报告与在学校选择FV和午餐主菜之间的关联。参与者(n = 59)是从小学儿童中选取的便利样本。采用中位数分割法将学生分为在家中接触和消费自我报告的高暴露组和低暴露组。主要因变量是在学校选择FV的自我报告;孩子们对八种“更健康”午餐主菜的绝对评分和相对评分;以及选择这些主菜的自我报告。这些主菜最近被添加到学校菜单中,因此孩子们对它们往往不太熟悉。通过在学校进行的口味接触来收集食物评分。结果表明,在家中报告更频繁接触FV的孩子在学校食用了更多种类的FV,并且更有可能报告在学校午餐时选择了“更健康”的主菜。这些数据表明,接触和消费各种FV可能会使孩子们更愿意选择更广泛的FV和其他健康主菜。
