Plate Design Increases Fruit & Vegetable Consumption in Children

Practical tool to impact children's nutrition environment

by Ashley Jordan Ferira, PhD, RDN

Color your plate, so the slogan goes. A 2018 study took this advice literally, incorporating pictures of fruits and vegetables (F&V) into school lunch plates with the goal of improving F&V consumption in preschoolers.1

F&Vs are a low-calorie, nutrient-dense (macro-, micro-, and phytonutrients) food group, but the US is getting a “failing grade” when it comes to F&V intake because typical Western diets are lacking in plant-based nutrition. Health behaviors, including dietary consumption patterns, start in early childhood and directly shape long-term practices.

On average, US preschool-aged children (ages 2-5) are consuming 0.48 cup-equivalents per 1,000 calories (CEPC)/day of vegetables and 0.97 CEPC/day of fruits.2 While whole fruit intake increased from the early 2000s to the year 2010, vegetable intake remained stagnant and subpar. 2 To date, no sociodemographic group meets the Healthy People 2010 target of 1.1 CEPC/day of vegetables.3 Schools are uniquely and regularly positioned to affect the nutrition environments of children. A 2012 study in elementary school children demonstrated that lunch trays with photographs in F&V compartments netted increased F&V consumption.4 The 2018 study adds to this evidence base, for the younger preschool-age group.1

The researchers sought to change the decision environment, making F&V consumption more likely in the young children.1 Children ages 3-5 (N=235; 51% female) across 18 preschool classrooms in Arvada, Colorado participated in the experiment, which included baseline and intervention periods, both consisting of 3 school days in a 1-week period.1 The intervention- segmented plates with F&V sections designated by pictures- took place 4 weeks after baseline (plain white plates), but lunch menus were identical in both baseline and intervention periods across all preschools.1 On day 1 of the intervention, children received a 5-minute introduction of the intervention plate to confirm they understood that pictures indicated designated spots for F&V; the children served themselves from F&V serving bowls and ate in their classrooms.1

Compared to the baseline period, calculations indicated that the children:1

  • Served themselves more vegetables during the intervention (↑13.8g/day/child on average, p<0.001)
  • Consumed more vegetables during the intervention (↑7.5g/day/child on average, p=0.001)
  • Served and consumed more fruits during the intervention (not statistically significant)

Other noteworthy findings: The children may have had a particular affinity to cucumbers and carrots, since the strongest increase in vegetable selection/consumption occurred on the day they were served (day 2).1 Lastly, in correlation analyses, the segmented, pictorial plates were associated with significant increases in the amount of vegetables taken and consumed per child, but similar associations were not seen for fruits; the authors conjecture this may be due to a ceiling effect, since the children were already taking 88.5% of fruits available at baseline.1 

Why is this Clinically Relevant?

  • Fruit and vegetable (F&V) intake is lacking2-3 and represents an obvious target for lifestyle intervention
  • Practitioners, educators, and guardians are stakeholders who can affect the nutrition environments of children; especially since behaviors obtained during early childhood are associated with positive lifelong dietary practices. Therefore, improving daily F&V intake is “low-hanging fruit” with potential to support a healthy weight and mitigate chronic disease trajectory
  • Incorporating pictorial designs of healthy foods on plates/trays should be considered to increase consumption in children1,4
