An online study examining children's selection of vegetables at mealtimes: The role of meal contexts, variety and liking

Associative learning predicts that children expect to eat vegetables together with foods high in carbohydrate and protein at mealtimes. However, choosing to eat and consume vegetables may be less likely if they are presented alongside more palatable, competing foods. This study examined food choices of children (N = 180, 8-11 years, 84 female) in a mealtime context. During an online task, children chose one food for a meal, from a choice of vegetables and either a food high in carbohydrate or protein. Preference was assessed with and without a partial meal stimulus, to test the effect of other foods on the plate. Vegetables were selected more often with a meal stimulus, especially when it consisted of carbohydrate and protein foods, meaning that the vegetable option added nutritional variety to the meal. This effect was moderated by the difference in liking between the food options available. Vegetables were selected more if they were better liked than the competing food option, although it was not necessary that vegetables were better liked if they added nutritional variety to the meal. Food fussy children were less likely to select vegetables, but no other effects of child appetitive traits or parental practices were found on children's food choices. Children may be more likely to select vegetables if they add nutritional variety to a meal and are similarly or better liked than competing food options. Future research could test specific meal configurations which promote children's selection and intake of vegetables at mealtimes.
