I study the evolution of the quality of grocery purchases among migrants to learn how changes in the environment affect dietary choice. Using detailed household level panel data on food purchases I find that healthfulness of grocery purchases is very persistent in the short-run. Three to four decades after moving, however, households have closed about half of the gap in healthfulness between the origin and destination area. The results suggest that dietary habits are highly persistent, but may eventually shift in the face of different local environments.
我研究移民在食品杂货购买质量方面的演变，以了解环境变化如何影响饮食选择。使用关于食品购买的详细家庭层面面板数据，我发现食品杂货购买的健康度在短期内非常持久。然而，在搬入后的三到四十年后，家庭在原籍地和目的地之间的健康度差距缩小了约一半。结果表明，饮食习惯非常持久，但最终可能会在面对不同的当地环境时发生转变。
