Yellow-sticker shoppers are wanted for interviews
The academics are hoping to take their research on by directly interviewing those involved in yellow-sticker shopping.
They want to speak to people who shop for yellow-sticker food to find out more about their experience and learn more about why and how they shop in this way.
They also want to ask shoppers to document their purchases by taking pictures and keeping diaries and receipts, and then follow this food into the kitchens of shoppers to see how yellow-sticker food is stored, prepared and eaten.
Those interested can email Sarah Kelsey, one of the co-authors of the paper.
