Effectiveness of front-of-pack nutrition symbols: a pilot study with consumers.

PURPOSE: The effectiveness of different front-of-pack nutrition rating systems and symbols (FOPS) has not been studied among Canadians. We pilot tested an online FOPS survey with consumers. METHODS: Members of the Guelph Food Panel were randomly exposed to traffic light, Percent Daily Value, Health Check, and Smart Pick logos on mock food packages and were asked to rate the FOPS on a Likert-type scale. The FOPS were rated on consumers' ability to understand them, credibility, and influence on purchase decisions. Participants also provided feedback on the survey. RESULTS: Participants (n=337) deemed the survey appropriate in length and language, and provided suggestions for improving survey clarity. More than 50% of the respondents believed that FOPS should be present on all food packages (65.1%) and should be government regulated (53.0%). The Percent Daily Value symbol was rated highest with respect to liking, credibility, helpfulness, and influence, but was the least understood. When they used direct comparison, consumers preferred the traffic light symbol (53.1%) over the Percent Daily Value (40.0%), Health Check (6.7%), and Smart Pick (0.3%) symbols. CONCLUSIONS: The survey was revised as a result of the pilot study feedback. Preliminary findings from this pilot study suggest that consumers prefer a single, government-regulated symbol, and value more complex FOPS, like the Percent Daily Value symbol, despite finding them harder to understand.

Consumer perceptions of the Nutrition Facts table and front-of-pack nutrition rating systems.

Preferences for, and consumer friendliness of, front-of-pack (FOP) nutrition rating systems have not been studied in a Canadian population, and studies comparing systems that are accompanied by mandatory labelling, such as Canada's Nutrition Facts table (NFt), are lacking. The purpose of this study was to evaluate 4 FOP systems relative to the NFt with respect to consumer friendliness and their influence on perceptions of the healthiness and nutrient content of food. Canadian consumers (n = 3029) participating in an online survey were randomized to score the consumer friendliness of 1 of 5 FOP conditions with or without an NFt and to score the healthiness and nutrient content of 2 foods using the provided label(s). The mean differences in scores were evaluated with analysis of covariance (ANCOVA) controlling for age, gender, and education, with Tukey-Kramer adjustments for multiple comparisons. The NFt received the highest scores of consumer friendliness with respect to liking, helpfulness, credibility, and influence on purchase decisions (p < 0.05); however, consumers still supported the implementation of a single, standardized FOP system, with the nutrient-specific systems (a "Traffic Light" and a Nutrition Facts FOP system) being preferred and scored as more consumer friendly than the summary indicator systems. Without the NFt, consumer ratings of the healthiness and calorie and nutrient content differed by FOP system. With the NFt present, consumers rated the healthiness and calorie and nutrient content similarly, except for those who saw the Traffic Light; their ratings were influenced by the Traffic Light's colours. The introduction of a single, standard, nutrient-specific FOP system to supplement the mandatory NFt should be considered by Canadian policy makers.
