Buying a bigger package of chocolate bars to share with your friends? Or sharing fries at a restaurant with your partner? How does that impact your health?
The popularity of share-size snacks and shared plate options in restaurants has grown and so did concerns over how food sharing may be impacting health. Nükhet Taylor (Ryerson University) and Theodore J. Noseworthy (York University) address this question in their current research. Their empirical studies suggest that food sharing reduces perceived ownership, which, in turn, leads people to mentally decouple calories from their consequence. Sharing food is not biasing caloric estimates but sharing is biasing how consumers construe the consequence of their caloric intake. Lower perceived ownership makes caloric intake seem inconsequential as food appears less fattening when it is shared.
