Abstract

Front-of-Pack Nutrition labels (FOPNLs) aim to improve consumers’ food purchases and prompt product reformulation by the food and beverage industry. Despite their widespread use, the effectiveness of FOPNL in achieving these goals is still a matter of debate. This review has gathered 65 original studies exploring the performances of four widely used FOPNLs (Multiple Traffic Light, Warning signs, Nutri-Score and Health Star Rating). Although FOPNLs have been associated with healthier food purchases, the magnitude of improvements was small and dependent on study settings. Any associated health effects were modeled rather than observed. None of the four FOPNLs clearly outperformed the other ones on any outcome. Few studies dealt with the impact of FOPNL on product reformulation. Some of those studies, but not all, found small reductions in energy, sodium, sugar and saturated fat content of foods in some food categories. Although global trends point to a small favorable effect of FOPNL, this conclusion is subject to caution since the evidence is inconsistent and comes from a wide variety of contexts and study designs. There remain numerous research gaps, notably with regard to the optimal characteristics of FOPNLs, the durability of FOPNL effects on consumer behaviors, and any possible unexpected consequences.

  • The PEF label's current alternative formats are based upon complex cue systems that have demonstrated very mixed effectiveness as an arbiter of consumer evaluation and choice in FMCG purchase situations.

    “all alternative current formats of it are based upon complex cue systems of a type that has demonstrated very mixed effectiveness as an arbiter of consumer evaluation and choice in FMCG purchase situations [13,14]”

    From Marketing Tactics for Sustainable Fashion and the Circular Economy: The Impact of Ethical Labels on Fast Fashion Choice (2023) · cites this paper as [13]

    The Results (§3.1) say that real-life studies found mixed effects of front-of-pack nutrition labels on food purchases, and the Discussion (§4.1) reports mixed evidence about their influence on healthier choices. The paper does not address PEF labels or establish that their alternative formats use complex cue systems; its findings concern nutrition labels on foods, not FMCG purchases generally.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
