Abstract

True dietary change typically occurs through consumer preferences, and when changes in product attributes reflect these preferences, category‐level demand can be substantially rearranged. In this study, we show that a successful new product may fundamentally change the nature of an entire category, and change consumers' nutrient consumption by altering the nutrient content of the food products they consume. Greek yogurt, for example, offers a very different combination of nutrients relative to other types of yogurts. The fact that it was immediately successful after its introduction provides an example of a transformational new product—one that potentially changed the nutrient‐consumption profiles of yogurt buyers. We use a quasi‐experimental approach with propensity score matching (DiD + PSM) to identify the effect of introducing Greek yogurt on yogurt buyers’ nutrient consumption. We find that the introduction of Greek yogurt led to yogurt purchases with greater overall protein and calorie content, but lower fat and carbohydrate content. We use the case of Greek yogurt to show that a relatively simple innovative common consumer product can have far‐reaching implications for the nature of nutrients consumed from that category. Our findings point to the importance of information policies, and their interaction with consumer preferences, on changing dietary outcomes. Les véritables changements alimentaires surviennent généralement à travers les préférences des consommateurs, et lorsque les caractéristiques des produits évoluent pour refléter ces préférences, la demande au niveau d'une catégorie peut être profondément réorganisée. Dans cette étude, nous montrons qu'un nouveau produit réussi peut transformer fondamentalement la nature d'une catégorie entière et modifier la consommation de nutriments des consommateurs en changeant la composition nutritionnelle des aliments qu'ils consomment. Le yogourt grec, par exemple, offre une combinaison de nutriments très différente de celle des autres types de yogourts. Le fait qu'il ait connu un succès immédiat après son introduction constitue un exemple de produit véritablement transformateur — susceptible d'avoir modifié les profils de consommation de nutriments des acheteurs de yogourt. Nous utilisons une approche quasi expérimentale avec appariement par score de propension (DiD + PSM) afin d'identifier l'effet de l'introduction du yogourt grec sur la consommation de nutriments des acheteurs de yogourt. Nous constatons que cette introduction a entraîné des achats de yogourt présentant une teneur globale plus élevée en protéines et en calories, mais plus faible en lipides et en glucides. À travers le cas du yogourt grec, nous montrons qu'un produit de consommation courant, relativement simple mais innovant, peut avoir des répercussions importantes sur la nature des nutriments consommés au sein de cette catégorie. Nos résultats soulignent l'importance des politiques d'information, ainsi que leur interaction avec les préférences des consommateurs, dans la transformation des habitudes alimentaires.
