There is a lot of confusion when it comes to understanding nutrition information on food packages, thus making it difficult for consumers to choose healthy products. In today's busy and fast-paced shopping environment, mobile digital technology (for example, Smartphone applications) can help consumers make 'healthier' food choices when they are shopping. This study aims to test the effectiveness of a traffic light front-of-pack system, the Health Star Rating System (HSR or Star System), and the proposed sodium, saturated fat and sugar warning labels proposed by Health Canada. The study will also experimentally test the use of a Smartphone application (app), FoodFlip, to help educate consumers on these systems on food packages to explore the impact of a learning effect on the efficacy of the labelling systems.
