Background: Many commercial infant and toddler foods (CITFs) contain added sugars, posing health risks to consumers. Front-of-pack nutrition content claims can create a ‘health halo’ over sugary products, whereas warning labels could be effective in raising awareness of potential harms.
Aims: Test whether displaying Added Sugar Warning labels (‘warning labels’) and removing nutrition content claims on sugary CITFs helps parents evaluate products and prompts purchasing of CITFs without added sugar.
Methods: Using an online shopping experiment, 1,017 Australian parents of infants and toddlers (6 to <36 months) were randomly assigned to one of four conditions, using a 2 (warning label: control/warning) X 2 (claims: absent/present) between-subjects design. Parents viewed screens displaying twelve infant/toddler CITFs (six with added sugar, six without), featuring labels and claims reflecting their condition. Regression analyses tested effects of warning labels and no claims on product perceptions, purchasing choices and intentions.
Results/findings: Significant main effects (all p<0.05) showed that cf. control condition, warning labels: reduced parent’s likelihood of choosing CITFs with added sugar (82% vs. 53%); mean purchasing intentions (M: 4.93 vs. 3.80); perceptions of suitability (M: 4.65 vs. 3.70), naturalness (M:4.55 vs. 3.82), healthiness (M: 4.48 vs. 3.76), and fibre content (M: 4.44 vs. 4.05); but increased perceptions of the level of added sugar (M: 4.70 vs. 5.70), total sugar (M: 4.62 vs. 5.07) in CITFs with added sugar, irrespective of whether nutrition content claims were displayed or not (no main effects or interactions with warning labels).
Conclusions: Displaying warning labels on CITFs containing added sugar detracts from parents’ perceptions of the healthiness and suitability of these products and reorients their purchasing preferences towards lower sugar options, even in the presence of nutrition content claims. Warning labels offer a promising policy option to inform parents about added sugars in CITFs, nudging them towards healthier choices.
