News coverage of Mexico’s front-of-package food label policy

Abstract

ObjectivesTo examine news coverage of Mexico’s front-of-package food labelling policy.MethodsWe used Lexis Nexis to identify newspaper articles that mention the proposed law in four Mexican newspapers representing politically centre-left and centre-right perspectives. We coded for type and valence of arguments, sources and research evidence cited.ResultsWe identified N=361 relevant articles. Coverage of the front-of-package food label policy was primarily news (vs editorial/opinion). While most were neutral in tone, left-leaning newspapers had slightly more positive overall coverage compared with right-leaning newspapers, indicated by publishing more stories in favour of the policy, fewer in opposition, more propolicy arguments and more frequent inclusion of perspectives by government officials and public health advocates. Despite some evidence of bias, there was a general lack of credible opposition to the policy and mention of opponents across newspapers.Conclusions and policy implicationsThe relative absence of food and beverage industry stakeholders in news coverage of the food label policy is unexpected given their documented involvement in prior food policy debates. We discuss possible reasons for their conspicuous absence and lessons for public health advocates around the globe.
