Abstract While repeated exposure is an established method for inducing food acceptance in young children, little is known about parents’ experiences of repeatedly offering new or disliked foods at home. In this study, parents kept structured diary records during a 15-day period in which they offered their 2-year-old child daily tastes of one fruit and one vegetable. We explored how children’s acceptance of foods (measured in terms of willingness to taste, liking and intake) and the ease and enjoyment of the process for parents changed from the early (days 1–5) to middle (days 6–10) to later (days 11–15) phases of exposure. In addition, we explored whether prior visual familiarization to foods affected children’s behavior and/or parents’ experiences during exposure. Families were randomly assigned to look at a picture book about one to-be-exposed food for the two weeks prior to the exposure phase (‘fruit book’ and ‘vegetable book’ groups) or to a control group, who did not receive a book. Measures obtained from parents’ diary records revealed increases in willingness to taste and intake of vegetables and increased liking of both fruits and vegetables with greater exposure. Prior visual familiarization to vegetables further boosted children’s willingness to taste and liking of vegetables, and the ease and enjoyment of introducing these for parents. Children’s acceptance of foods and parents’ positivity during exposure predicted children’s liking and intake of foods 3 months later. Results confirm the potential for vegetable picture books to support parents in engaging with repeated exposure regimes and in successfully introducing vegetables into toddlers’ diets.

父母通过反复接触向幼儿介绍水果和蔬菜的经验，无论是否事先对食物进行视觉熟悉：来自日常日记的证据

摘要 虽然反复接触是诱导幼儿接受食物的既定方法，但对父母在家里反复提供新的或不喜欢的食物的经历知之甚少。在这项研究中，父母在 15 天的时间内保持结构化的日记记录，其中他们每天为 2 岁的孩子提供一种水果和一种蔬菜的口味。我们探讨了儿童对食物的接受度（以品尝、喜欢和摄入的意愿来衡量）以及父母对食物的接受程度如何从早期（第 1-5 天）到中期（第 6-10 天）到后期发生变化（第 11-15 天）暴露阶段。此外，我们探讨了先前对食物的视觉熟悉是否会影响儿童在暴露期间的行为和/或父母的体验。家庭被随机分配在暴露阶段前两周看一本关于一种将要暴露的食物的图画书（“水果书”和“蔬菜书”组）或一个对照组，他们没有接受书。从父母的日记记录中获得的测量结果显示，品尝和摄入蔬菜的意愿增加，并且对接触较多的水果和蔬菜的喜好增加。事先对蔬菜的视觉熟悉进一步提高了孩子们品尝和喜欢蔬菜的意愿，以及为父母介绍这些蔬菜的轻松和愉快。暴露期间儿童对食物的接受度和父母的积极性可以预测 3 个月后儿童对食物的喜好和摄入量。
