Not Applicable

Completed

• Conditions: Vegetable Intake After Weaning With Vegetables or Fruits; Fruit Intake After Weaning With Vegetables or Fruits
• Interventions: Other: green beans group; Other: Artichoke group; Other: Apple group; Other: Plums group

• Registration Number: NCT01858337
• Lead Sponsor: Wageningen University

Brief Summary

* Rationale: Despite the health benefits, children's consumption of vegetables is below the recommendations. Most human food preferences are learned through mere exposure, imitation, and conditioning principles. During the last years, it has become clear that the development of food preferences starts very early in life. Furthermore, preferences that are learned early in life, are relatively stable and may track into adulthood. However, it is unclear how vegetable preferences develop from infancy until young childhood. In order to influence vegetable consumption, it is essential to study the opportunities to develop a preference for vegetable products early in childhood.

* Objective: The aim of this study is to investigate the effect of repeated exposure to vegetables compared to repeated exposure to fruit during weaning on short and long term vegetable and fruit intake. Furthermore, the stability of the learned fruit or vegetable preferences and the later food preferences are measured (i.e. vegetable, fruits, sweets).

* Study design:

In this longitudinal study we will measure the development of preferences for a particular vegetable or fruit type within 4 to 6 months old subjects, during a 19 day exposure period to fruit or vegetables (of which 9 days exposure to the target fruit or vegetable) and 6 months after this exposure period. In addition, we compare the food preferences (fruit, vegetable, sweet foods in general), after 6 months, between infants who were weaned with a variety of fruits and infants who were weaned with a variety of vegetables.

Artichoke group	Artichoke group	1 of the 2 vegetable groups. The infants were weaned only with vegetables. With Artichoke every other day and another vegetable on the days in between
Apple group	Apple group	1 of the 2 fruit groups. The infants were weaned only with fruits. With Apple every other day and other fruits on the days in between
Plums group	Plums group	1 of the 2 fruit groups. The infants were weaned only with vegetables. With Plums every other day and other fruits on the days in between

Primary Outcome Measures

Name	Time	Method
Change in Vegetable and fruit intake	At the first 19 days of weaning (4-6 months of age)	Change in Vegetable and fruit intake from before to after the repeated exposure to it. Measured at day 1 and 2 and day 17 and 18 at the intervention.
Intake of the target Vegetables and fruits at 12 months of age.	6 months after the intervention. Mean age 12 months.	Vegetable and fruit intake at 12 months of age. Measured in the lab. Fruit group received apple, plum and green beans at 3 different days
Green beans and Apple intake at 23 months of age.	when infants are 23 months of age	Green beans and Apple intake at 23 months of age.

Secondary Outcome Measures

Name	Time	Method
Vegetable and in fruit intake after the repeated exposure	After the repeated exposure period during the first 19 days of weaning	Difference in vegetable intake between vegetable and fruit groups and in fruit intake between the vegetable and fruit groups. Vegetable intake is measured on day 17 and 18 in the vegetable groups and in the fruit groups at day 19 (when fruit groups gets the first vegetable.
