Designing online grocery stores to support healthy eating for weight loss

Content Analysis of Online Grocery Retail Policies and Practices Affecting Healthy Food Access

OBJECTIVE

To describe policies and practices of online grocery retailers that may affect healthy food access, including retailers participating in the US Department of Agriculture's Supplemental Nutrition Assistance Program Online Purchasing Pilot.

DESIGN

Cross-sectional, quantitative content analysis of 21 online grocery retail websites from November 2019 to January 2020.

MAIN OUTCOME MEASURES

Data collected using a coding instrument capturing the presence of policies and practices related to (1) online purchasing and delivery access; (2) availability of features that allow price comparisons and provide nutrition information; and (3) data privacy.

ANALYSIS

Descriptive statistics for features, practices, and policies across online grocery retail websites.

RESULTS

Most retailers (95%) added fees to online orders. Among pilot retailers, 38% added ≥ 3 fees, and 50% required a minimum order > $15. Few retailers (29%) displayed Nutrition Facts Labels on all products, including 50% of pilot retailers. All retailers collected personal information from shoppers and automatically shared data with affiliated companies.

CONCLUSIONS AND IMPLICATIONS

High fees, limited access to nutrition information on retailer sites, and lack of data privacy are prevalent in online grocery retail settings, including among Online Purchasing Pilot retailers. Online retail practices may perpetuate disparities in healthy food access by discouraging use through fees and making nutritious food choices difficult.

Digital Food Retail: Public Health Opportunities

For over two decades, digital food retail services have been emerging alongside advances in mobile technology and improved access to wi-fi. Digitalization has driven changes within the food environment, complicating an already complex system that influences food-related behaviors and eating practices. Digital food retail services support an infrastructure that enhances commercial food systems by extending access to and availability of highly processed foods, further escalating poor dietary intakes. However, digital food retail services are heterogeneous–food delivery apps, online groceries, and meal kits–and can be feasibly adapted to nutrition interventions and personalized to individual needs. Although sparse, new evidence indicates great potential for digital food retail services to address food insecurity in urban areas and to support healthy eating by making it easier to select, plan, and prepare meals. Digital food retail services are a product of the digital transformation that reflect consumers’ constant need for convenience, which must be addressed in future research and interventions. This paper will discuss public health opportunities that are emerging from the global uptake of digital food retail services, with a focus on online groceries, food delivery apps, and meal kits.
