简要总结
This is an online study that aims to test the effectiveness of Interpretative Nutrition Rating Systems (INRS) such as the Health Star Rating System (HSR or Star System), traffic light system and warning labels (high sodium, saturated fat and sugar) proposed by Health Canada. The study will incorporate the use of a Smartphone application (app), FoodFlip®, to help educate consumers on each INRS prior to their exposure on food packages.

结局指标
主要结局
Comprehension task - ability to identify unhealthy products (survey measure)
时间窗: 1 day (assessed immediately after app task and while viewing products with labelling system applied
The participant's ability to identify the least healthy product in a group of products in a group of 5 products in a task rating 5 products with varying levels of 'healthiness' according to modified FSANZ criteria. Question wording: Please rank these products in terms of healthiness where 1 is the"most healthy" and 5 is the "least healthy" cereal
