Food purchasing and consumption behaviors have implications for nutrition and obesity. Food retail environments, in particular, shape customer food choices and energy intake. The marketing literature offers insights about how public health practitioners can work within food retail environments to encourage healthy food choices. We reviewed experimental studies in the marketing literature to examine factors influencing customer purchase intentions and choice for food products in retail stores. Database searches were conducted in February 2016 for original, empirical articles published in English from 2000⁻2015 in marketing journals. Each research article included at least one experimental design study conducted in a real or simulated retail environment with purchase intentions or choice of food products as an outcome variable. Backward and forward reference searches were conducted for articles meeting inclusion criteria. Narrative synthesis methods were used to thematically group and summarize the findings of forty-one articles that met inclusion criteria into three categories: shelf display and product factors, pricing and price promotion factors, and in-store and customer decision-making factors. This research contributes to the literature by providing specific and actionable approaches that can increase/decrease customer purchase intentions and choice for food products in retail environments. Translating marketing strategies into public health applications can provide recommendations for future intervention research and policy related to customer food purchasing behavior.
