Study Type: Interventional

Study Design: Basic Design - Single arm Randomization - Non-randomized Blinding - Open -no one is blinded Control - Self control

Primary Sponsor: Institute - Kewpie Corporation

Condition: Condition - Healthy children and their parents Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - This study aims to evaluate the effects of cooking activities using potato salad on salivary oxytocin and cortisol concentrations in elementary school children (aged 6 to 12 years) and their parents. By focusing on parent-child interactions specifically, children's proactive cooking challenges and parents' supportive observation we will investigate whether this experience improves children's vegetable intake. Furthermore, the study seeks to clarify the impact of these activities on building a trusting parent child relationship. Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - Cooking activities using potato salad (child-led cooking and parent's observation) Under the guidance and assistance of the research staff, subjects will prepare an arranged potato salad. During the cooking process, parents will observe their children, providing encouragement and setting an environment that allows the children to proactively engage in the activities.
