Study Details

Brief summary:

The goal of this study is to examine what type of front-of-package label (FOPL) would be most effective at discouraging consumption of products high in nutrients of concern in Indonesia. The main questions this experiment aims to answer are:

1. Would nutrient warning labels be more effective at discouraging consumption of products high in nutrients of concern compared to the Nutri-Level label?
2. Would nutrient warning labels improve consumers' ability to identify unhealthy products compared to the Nutri-Level label?

Additionally, this experiment also aims to determine how should nutrient warning labels be designed to most effectively discourage consumption of products high in nutrients of concern among Indonesian consumers.
