Trans Fat Information on Food Labels: Consumer Use and Interpretation

Publication: Canadian Journal of Dietetic Practice and Research
16 February 2010

Abstract

Purpose: Consumers’ use and interpretation of trans fat information on food labels were explored.
Methods: Consumers completed an interviewer-administered questionnaire in one of three grocery stores selected purposively to represent geographical location. Data analysis involved examining the relationship of age, gender, grocery shopping habits, household size, and source of nutrition information with awareness, use, and interpretation of trans fat information.
Results: Ninety-eight percent (n=239) of participants were aware of trans fat, and most knew of the relationship between trans fat intake and cardiovascular disease. Although the majority of shoppers were aware of the “0 trans fat” nutrition claim on food packages (95%), they were more likely to use the Nutrition Facts panel (60%) to reduce trans fat intake. Men and consumers under age 40 were least likely to be aware of food label information. While most consumers (75%) correctly interpreted the “0 trans fat” nutrition claim and thought foods with this claim could be healthy choices (64%), only 51% purchased these foods to reduce trans fat intake.
Conclusions: Nutrition professionals should target messages to reduce trans fat intake at men and consumers under age 40. While general knowledge was good, further education is required to help consumers interpret trans fat information.

Résumé

Objectif: Explorer l'usage et l'interprétation de l'information au sujet des gras trans sur les étiquettes alimentaires.
Méthodes: Les consommateurs ont rempli un questionnaire administré par un intervieweur dans l'un des trois magasins d'alimentation choisis délibérément selon leur emplacement géographique. L'analyse des données consistait à examiner la relation entre d'une part l’âge, le sexe, les habitudes d'achat des aliments, la taille du ménage et la source d'information en nutrition et, d'autre part, la sensibilisation aux renseignements sur les gras trans ainsi que leur usage et leur interprétation.
Résultats: Au total, 98% (n=239) des participants connaissaient les gras trans et la plupart étaient au fait de la relation entre l'apport en gras trans et les maladies cardiovasculaires. Bien que la majorité des clients (95%) aient vu l'allégation nutritionnelle «0 gras trans» sur les emballages, ils avaient plutôt tendance à utiliser le tableau de valeur nutritive (60%) pour réduire leur apport en gras trans. Les hommes et les consommateurs de moins de 40 ans étaient moins susceptibles d’être sensibilisés à l'information sur les étiquettes alimentaires. Alors que la plupart des consommateurs (75%) ont interprété correctement la mention «0 gras trans» et pensaient que les aliments portant cette allégation pourraient être des choix sains (64%), 51% seulement en achetaient pour diminuer leur apport en gras trans.
Conclusions: Les professionnels de la nutrition devraient cibler les messages visant à réduire l'apport en gras trans chez les hommes et les consommateurs de moins de 40 ans. Bien que les connaissances générales aient été bonnes, il est nécessaire de fournir plus d'information pour aider les consommateurs à interpréter les renseignements sur les gras trans.
