     Kids won't eat their vegetables? Name them again, scientists say. In a new study, 186 four-year-old

children were given regular carrots and, on other lunch days, they were given the same vegetables which

were renamed X-ray Vision Carrots.

     The study suggests kids like vegetables with cool names better and the influence of these names might

continue to exist. Children continued to eat about 50 percent more carrots even on the days when they

were no longer called cool names.

     The research, which was funded (资助) by the Robert Wood Johnson Foundation, was put up at the

yearly meeting of the School Nutrition Association in Washington DC.

     "Cool names can make for cool foods," says Brian Wansink of Cornell University. "Whether it is '

power peas' or 'dinosaur broccoli trees,' giving the food a fun name gets kids to think that it will be more

fun to eat. And it seems to keep working-even on the next day," Wansink said.

     Similar results have been found with adults. A restaurant study showed that when the Seafood Filet was changed to Succulent Italian Seafood Filet, sales increased by 28 percent and the taste rating (评级)

increased by 12 percent. "The same food, but different expectations, and different experience," said

Wansink, the author of Mindless Eating: Why We Eat More Than We Think.

     The study was done in pre-schools (幼儿园), but the researchers believe the same tricks can work

with children                .

     "I've been using this with my kids at home," said a researcher Collin Payne. "Whatever inspires their

imagination seems to inspire their appetite (胃口)."
