Healthy lifestyle is a strong trend at the moment, but at the same time a fast growing number of people are becoming over-weight.Persuasive technologies hold promising opportunities to change our lifestyles.In this paper, we introduce a persuasive shopping trolley that integrates two tools of persuasiveness namely reduction and suggestion.The trolley supports shoppers in assessing the nutrition level for supermarket products and provides suggestions for other products to buy.A field trial showed that the persuasive trolley affected the behaviour of some shoppers especially on reduction where shoppers tried to understand how healthy food products are.On the hand, the suggestion part of the system was less successful as our participants made complex decisions when selecting food.
