SwapSHOP

This research is testing whether a smartphone app can help people to make healthier food choices when shopping for groceries.

  • During the first two weeks of the study, participants will scan and record all of their grocery shopping (food and drink). Participants will then be randomly allocated to one of six groups, three of which will receive in-app suggestions of healthier alternatives to some of their normal food choices.
  • Monitoring of food purchases will be done by scanning product barcodes, which will then be stored in the app. (If shopping at Waitrose, Morrisons or Iceland, products will need to be selected manually)
  • The study is being carried out by the Nuffield Department of Primary Care Health Sciences at the University of Oxford.

Criteria
