Give the students more time to get off campus for lunch.
In the continuing quest to improve the health quotient of school lunches, experts have proposed fancy chefs, cutesy lunch boxes and smiley-faced stickers. Now comes a more straightforward suggestion — just make the lunch period longer.
The idea that schools could persuade kids to eat better without making a single change to their cafeteria menus may sound pie in the sky, but its proponents have some data to back them up. After analyzing the eating habits of 1,001 elementary and middle school students in Boston-area schools, researchers found that the more time students had to finish their lunches, the more fruits and vegetables they ate and the more milk they drank.
One of the six schools that participated in the Modifying Eating and Lifestyles at School — or MEALS — study gave students as little as 20 minutes for lunch. Some of that time had to be spent getting to the cafeteria and standing in line when they got there. By the time they finally sat down with their trays, some kids had only 10 minutes to eat.
Of the other five schools in the study, two had a 25-minute lunch period and three set aside 30 minutes for the midday meal. The actual time to eat ranged from 10 minutes to 33 minutes (some teachers let their students go to lunch a little early), with an average eating time of 23.9 minutes.
The researchers, from Merrimack College in Massachusetts, the Harvard T.H. Chan School of Public Health and a Boston-based nonprofit called Project Bread, noticed two distinct trends.
First, the less time kids had to eat, the less likely they were to put fruit on their cafeteria trays. In schools where students had at least 25 minutes for lunch, 57 percent of kids chose a serving of fruit as part of their lunch. But when they had less than 20 minutes, only 44 percent selected fruit. Even kids with 20 to 24 minutes to eat opted for fruit only 47 percent of the time.
The study didn’t prove that short lunch periods caused kids to skip fruit, but the researchers said they doubted this was a coincidence. It’s likely that some of the students who were strapped for time went right by the fruit because they were “trying to rush through the lunch line to maximize their amount of time to eat,” they wrote. “It is also possible that these students recognized they would have less time to eat and therefore only selected foods they were likely to consume.”
