title: Eating better for less: a national discount program for healthy food purchases in South Africa.
abstract: OBJECTIVE
  To examine whether reducing prices for healthy food purchases leads to changes in self-reported measures of food consumption and weight status.
  
  
  METHODS
  Repeated surveys of about 350,000 HealthyFood participants and nonparticipants.
  
  
  RESULTS
  Program  participation is associated with more consumption of fruits/vegetables and whole-grain foods and less consumption of high sugar/salt foods, fried foods, processed meats, and fast food. There is no strong evidence that participation reduces obesity.
  
  
  CONCLUSIONS
  A substantial price intervention  might be effective in improving diets.
