• 1 other identifier: Miffy Study
• Study Type: interventional
• Target: 210
• Locations: 1 country
• Sites: 1

Brief Summary

Fruit and vegetable (F\&V) intake among children in western countries is below recommended levels. To increase F\&V consumption in children (3-6 years), a novel method is proposed based on the concepts of repetitive taste exposure, role models, and non-food rewards guided by the dietary advice: "Eat the rainbow: go for color!" The aim is to determine the effect of this intervention to stimulate the consumption of color on the willingness to try different fruits and vegetables in 210 children aged 3-7 years old

Outcome Measures

Primary Outcomes (1)

• Change in Willingness to try between

  Children's' willingness to try pieces of fruit and vegetables is measured in three levels. Children can either eat the study foods or try the study foods: A study food is considered as eaten when: • The piece of food is completely swallowed by the child; A study food is considered as tried when: * The piece of food has entered the mouth, but is spit out again; * The piece of food is eaten and swallowed, but only partly; The measures are taken by counting the number of pieces of F\&V, each of around 30 grams. Change in willingness to try is taken between the baseline session (week 1) and the intervention session (week 2)

  Two sessions (30 minuntes) in two weeks
