What drives the reduction in sodium intake? Evidence from scanner data
Some evidence suggests that sodium intake in the United States has been declining, but little is known about the driving forces behind this trend. We construct detailed, barcode-level information on the near-universe of packaged food products to isolate and quantify the role that product reformulation, vis-à-vis consumer purchasing behavior, has played in this decline. We find that product reformulation has been a driving force in the decline. Consumers, on the contrary, have gravitated towards saltier products. We provide analyses across socioeconomic and demographic groups and find that disparities in diet quality have exacerbated over time. We discuss the implications of our findings for effective diet improvement policies.
期刊介绍:
Food Policy is a multidisciplinary journal publishing original research and novel evidence on issues in the formulation, implementation, and evaluation of policies for the food sector in developing, transition, and advanced economies.
Our main focus is on the economic and social aspect of food policy, and we prioritize empirical studies informing international food policy debates. Provided that articles make a clear and explicit contribution to food policy debates of international interest, we consider papers from any of the social sciences. Papers from other disciplines (e.g., law) will be considered only if they provide a key policy contribution, and are written in a style which is accessible to a social science readership.
