Bigger dishes can cause adults to serve and consume more food, but a new study reveals that kids are also vulnerable to this bowl-size bias. Researchers Brian Wansink, Koert van Ittersum, and Collin Payne found that children will not only ask for more food to fill larger bowls-they'll also eat 52% more!
The kids requested 69% more cereal and milk when using large bowls and also ate 52% more! In addition to taking and eating more, kids with large bowls also wasted about 14% more food than those with small bowls. Interestingly, 78% of the kids in this study reported using the same size bowl as their parents at home, which may be causing them to over- serve and overeat.
Bigger bowls cause kids to request nearly twice as much food, leading to increased intake as well as higher food waste. Based on these findings, decreasing the size of plates and bowls may be an easy way to prevent kids from over-consuming. Having a separate set of smaller dishware for children may be a simple solution for caregivers who are concerned about their kids' caloric intake! [emphasis mine]
