Abstract

The presence of health claims on food packaging can positively bias consumers' evaluations of foods. This review examined whether cognitive biases endure when other sources of nutrition information [the nutrition facts panel (NFP) and front-of-pack labels] appear on-pack with health claims. The following databases were searched: Web of Science, Ovid, Google Scholar, ScienceDirect, Scopus, ProQuest, and Wiley Online Library. The search terms ("health claim*" OR "nutri* claim") AND ("food label*" OR "front of pack") were used to identify studies. Twenty-four studies that examined health claims and front-of-pack labels or the NFP were included. The NFP can reduce bias, but only if consumers view it and interpret it correctly, which often does not occur. Front-of-pack labels show greater promise in reducing bias created by health claims. These findings are relevant to policymakers who are considering the effectiveness of mandating an NFP and/or a front-of-pack label alongside health claims.

Keywords: front-of-pack label; health claim; nutrition panel; systematic review.
