"If your preschoolers turn up their noses at carrots or celery,a small re?ward like a sticker for taking even a taste may help get them to eat previously disliked foods," a UK study said.
Though it might seem obvious that a reward could encourage young chil?dren to eat their vegetables,the idea was actually controversial,researchers wrote in the American Journal of Clinical Nutrition. "That's because some studies have shown that rewards can backfire and cause children to lose interest in foods they already liked," said Jane Wardle,a researcher at University Col?lege London who worked on the study. Verbal praise,such as "Brilliant!You're a great vegetable taster. ” did not work as well.
The study found that when parents gave their small children a sticker each time they took a "tiny taste" of disliked vegetables,it gradually changed their attitudes. The children were also willing to eat more of the vegetables— either carrots,celery,cucumber,red peppers,cabbage or sugar snap peas― in laboratory taste tests,the study said.
Researchers randomly assigned (分派) 173 families to one of these groups. In one,parents used stickers to reward their children each time they took a tiny sample of disliked vegetables. The second group of parents used verbal praise. The third group,where parents used no special vegetablepro?moting methods,served as a "control".
Parents in the reward groups offered their children a taste of the "target" vegetables every day of 12 days. Soon after,children in the sticker group were giving higher ratings to the vegetables―and were willing to eat more in the re?search lab,going from an average of 5 grams at the start to about 10 grams af?ter the 12-day experience. The turnaround also seemed to last,with pre?schoolers in the sticker group .still willing to eat more of the once disliked veg?etables three months later.
Why didn't the verbal praise work? Wardle said the parents' words may have seemed' "insincere" to their children.
