Study: Junk foods widely available at elementary schools

Unhealthy snacks most prevalent in the South.

Junk food remains plentiful at the nation's elementary schools despite widespread efforts to curb childhood obesity, a new study suggests.

Between 2006 and 2010, nearly half of public and private schools surveyed sold sweet or salty snack foods in vending machines or other places, the study found.

There was little change over the four years, a surprising finding given vocal advocacy campaigns to improve kids' diets, said researcher Lindsey Turner, a health psychologist at the University of Illinois at Chicago and the study's lead author.

The study focused on snacks not sold during mealtimes, which until recently weren't subject to government nutrition standards.

Schools most likely to sell chips, cookies or similar foods were in the South, where obesity rates are the highest; these foods were scarcest at schools in the West.

vote buttons pins

On every other Thursday of our four-week cycle menu, we allow K-8 students to pick the entree choices. The media center specialist for each of the participating schools sets up the list of entree items on a computer for voting, and the winning entrees are given to cafeteria managers two weeks before the upcoming month to put into production. Students really like this, as it promotes ownership of the menu.

raised garden beds

We have raised garden beds that residents can reserve and use to grow their own plants. Whenever a resident brings me fresh produce from their own garden, I try and incorporate it into a dish. If I do end up using it, I will display the resident’s name and what the produce was next to the dish on the menu.

Curriculum for the mobile teaching kitchen centers around a single kid-friendly recipe, using ingredients that can provide talking points for nutrition, sustainability and food origins. “The recipe is the lesson,” Saidel says. “Every ingredient is an opportunity to talk.”

Earlier this year, Saidel, Perkins and Harvey did a student demo featuring roasted chicken and white bean tacos with greens and citrus salsa. “We can say, ‘Why are we using chicken instead of beef? Why are there some beans in here?’ You can talk about plant proteins and the sustainability and health message around...
