It might seem obvious this would entice youngsters to eat veggies. But the idea is considered controversial because rewards have been shown to backfire, causing kids to lose interest in all foods.
But, in this latest study in the American Journal of Clinical Nutrition, researchers only focused on the vegetables children didn't like. They were given a sticker for trying the tiniest amount.
Over time, those with the stickers not only ate more, but also started giving higher ratings to the vegetable they had previously sworn off.
Verbal praise on the other hand did not work so well...at least in this study.
