Better Eating Through Engineering
I’ve been interested in efforts to improve school lunches ever since my days as a reporter at the Seattle P-I, and here’s one of the coolest ideas I’ve run across: the “smart cafeteria.”
Despite our best efforts to get kids to love jicama sticks or broccoli spears, you can’t really force them to eat something they don’t want to. But this nifty New York Times interactive graphic, based on research from the Cornell Center for Behavioral Economics in Child Nutrition Program, demonstrates that subtle changes in the way food is presented and labeled can make a big difference in how many kids put it on their lunch tray.
The researchers explain their findings in today’s edition of The Atlantic, but here are some highlights:
- moving the salad bar in front of the cash register nearly tripled salad sales
- requiring students to buy cookies with cash (but allowing them to use lunch credits for fruit) increased fruit sales by 71 percent
- using smaller bowls decreased breakfast cereal portions by 24 percent
- keeping ice cream in a closed-top freezer reduced the number of takers by up to 30 percent
This isn’t rocket science. There’s a reason moms leave fruit in a bowl on the kitchen table and cookies in a closed jar. Grocery stores know that people pick up stuff as they’re waiting at the cash register. Fast food restaurants never forget to ask if you want fries with that. And plenty of other industries – from hospitals to auto manufacturers – have improved health outcomes through better engineering.
As I’ve documented in some detail, it’s not easy to overhaul menus in school cafeterias that are charged with magically turning pennies into healthy meals. And it’s important to advocate for nutrition policies and adequate spending that will help in those efforts. But these seem like easy fixes that would cost schools little to nothing and could make a real difference in fighting childhood obesity. And best of all, students aren’t likely to notice how much better they’re eating.
