Abstract
To examine the effects of exposure to conflicting nutritional information (CNI) through different forms of media on nutrition-related confusion and backlash among consumers in the UK. Cross-sectional survey administered via Qualtrics among 18-75-year-old participants in the UK. The sample was stratified by age and gender with quotas defined according to the 2011 UK census distribution. Qualtrics' Online panel of respondents in the UK. 676 participants comprising nearly an equal number of females (n 341) and males (n 335) and a majority (58·6 %) from households whose income was <£30 000. Our findings showed that nearly 40 % of respondents were exposed to some or a lot of CNI. We found that while exposure to CNI from TV and online news increased nutrition confusion, CNI from health professionals increased backlash. Exposure to CNI from social media and health websites was associated with reduced backlash. We also found that nutrition confusion and backlash were negatively associated with exercise behaviour and fruit and vegetable consumption, respectively. Our study supports the theoretical pathways that explain the influence of CNI exposure on nutrition-related cognitive and behavioural outcomes. Additionally, different types of online information sources are associated with these outcomes to varying degrees. In the context of obesity and diabetes rates in the UK, our findings call for (a) further experimental research into the effects of CNI on consumers' diet-related cognitions and behaviours and (b) multi-stakeholder, interdisciplinary approaches to address this problem.
Highlights
Should we be more concerned about consuming plant-based diets and less concerned about consuming processed red meat? Should we heed the findings of nutrition scientists if they are poised to continue contradicting each other? And should we change our dietary behaviours based on the information we receive from news and social media given how inconsistent it is? The aim of this paper is to examine the extent to which exposure to conflicting nutritional information (CNI) from various information sources shapes nutrition-related cognitive responses and behaviours among consumers in the UK
We found that participants were most exposed to CNI from television, online news and social media and were least exposed to it from doctors and health professionals
We sought to adapt Lee et al.’s (2018) model which looked at the varying influence of different media sources on nutritionrelated confusion and backlash, and subsequent effects on individual-level food consumption and exercise
Summary
They further studied the extent to which nutrition confusion and backlash affected fruit and vegetable consumption and exercise-related behaviours. Internet TV Print Lay people Health professionals Confusion Backlash Servings of fruit and vegetables Exercise frequency
