Adults with lower incomes are disproportionately affected by poverty, food insecurity, obesity, and diet-related non-communicable diseases (NCDs). In 2020–2021 amid the coronavirus disease 2019 (COVID-19) pandemic, the United States Department of Agriculture (USDA) expanded the Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot program to enable eligible participants to purchase groceries online in 47 states. This expansion underscores the need for SNAP adults to have digital literacy skills to make healthy dietary choices online. Currently, a digital literacy model does not exist to help guide USDA nutrition assistance policies and programs, such as SNAP. We conducted a systematic scoping review of the academic and gray literature to identify food, nutrition, health, media, financial, and digital literacy models. The search yielded 40 literacy models and frameworks that we analyzed to develop a Multi-dimensional Digital Food and Nutrition Literacy (MDFNL) model with five literacy levels (i.e., functional, interactive, communicative, critical, and translational) and a cross-cutting digital literacy component. Utilization of the MDFNL model within nutrition assistance policies and programs may improve cognitive, behavioral, food security, and health outcomes and support equity, well-being, digital inclusion, and healthy communities to reduce obesity and NCD risks.
