Dr. Joe Price says we may not realize it, but that's the choice kids face in many elementary schools.
"These are kids that every minute spent eating was a minute less playing, and so, they'd eat what they could eat quickly and they'd hurry out,"
The Brigham Young University economics professor's research shows that simply having recess before instead of after lunch boosts fruit and vegetable consumption by 54 percent.
The study also showed a 45 percent increase in the number of kids eating at least one serving of vegetables.
It's a simple trick, but it's working at Silver Creek Elementary School in Utah where the kids work up an appetite outside before coming into lunch.
Price says the fact that kids could clear their plate is startling, when you consider more than half of the healthy stuff is thrown away.
If you catch kids at the right time, he says, it seems they'll eat more greens.
When kids eat healthier, Price says, they perform better in the classroom and come home satisfied and less likely to binge on junk food.
