Summary
This study will be an online 3-arm randomized controlled trial. Here intervention group 1 will receive the intervention in the form of an animated cartoon "scrollytelling" outlining the various changes and reasons for changes in public health guidelines in the context of nutrition (e.g. recommendations on fat intake). Intervention group 2 will have a scrollytelling on the reasons why public health recommendations always change in the context of infectious disease control (e.g. during the COVID-19 pandemic). And finally, the control group will receive no intervention.
