Brief Summary

This study examines the impact of offering strategies on the fruit and vegetable intake of children aged 4-6. Two key factors being explored are whether caregivers initiate the offering or if it's freely provided and whether children have a choice in selecting fruits and vegetables. The objective is to determine how these strategies affect the children's fruit and vegetable intake. The research follows a 2x2 factorial cross-over design, with participants exposed to four different conditions. Interventions involve home visits, informed consent, questionnaires, and children tasting vegetables to assess their preferences. A SnackBox is placed in the home, and parents ensure it's filled based on the condition - children either choose a snack vegetable or have it initiated by parents. Daily questionnaires about vegetable consumption are completed, and the study concludes with material collection. The study includes 44 children aged 4-6 and carries minimal risks with no immediate benefits. Caregivers spend around four hours participating in the study.
