title: The effects of a nutrition education intervention on vending machine sales on a university campus.
abstract: OBJECTIVE
  To determine the effects of a nutrition information intervention on the vending machine purchases on a college campus.
  
  
  METHODS
  Five high-use vending machines were selected for the intervention, which was conducted in the fall of 2011. Baseline sales data were collected in the 5 machines prior to the intervention. At the time of the intervention, color-coded stickers were placed near each item selection to identify less healthy (red), moderately healthy (yellow), and more healthy (green) snack items. Sales data were collected during the 2-week intervention.
  
  
  RESULTS
  Purchases of red- and yellow-stickered foods were reduced in most of the machines; moreover, sales of the green-stickered items increased in all of the machines.
  
  
  CONCLUSIONS
  The increased purchases of healthier snack options demonstrate encouraging patterns that support more nutritious and healthy alternatives in vending machines.
