Front-of-pack nutrition labelling: are multiple formats a problem for consumers?

"Conflicts of interest : None declared."

"Funding The study was funded exclusively by the UK Food Standards Agency, contract PAU 217. Conflicts of interest: None declared. Key pointsThis is the first study that has comprehensively examined how people actually use different FOP labels to make comparisons and judgements about the healthiness of food products using different label formats.Lack of standardization in FOP labels, for instance, in the use of colour across schemes, causes confusion and can lead to incorrect inferences being made.Making comparisons across label formats was frustrating and time-consuming deterring usage in a real-life situation.Label usage and impact in promoting healthy food choices may be enhanced by achieving greater consistency in the FOP format."
