Abstract
Purpose of the Review
Describe the state of knowledge on how the retail food environment contributes to diet-related health and obesity among Indigenous populations, and assess how the literature incorporates Indigenous perspectives, methodologies and engagement throughout the research process. Outcomes included dietary behaviour (purchasing, intakes and diet quality) and diet-related health outcomes (weight-related outcomes, non-communicable diseases and holistic health or definitions of health as defined by Indigenous populations involved in the study).

Recent Findings
Of fifty included articles (1996–2019), the largest proportions described Indigenous communities in Canada (20 studies, 40%), the USA (16, 32%) and Australia (9, 18%). Among articles that specified the Indigenous population of focus (42 studies, 84%), the largest proportion (11 studies, 26%) took place in Inuit communities, followed by Aboriginal and Torres Strait Islander communities (8 studies, 19%). The included literature encompassed four main study designs: type A, dietary intakes of store foods (14 studies, 28%), and type B, store food environments (16, 32%), comprised the greatest proportion of articles; the remainder were type C, store food environments and diet (7, 14%), and type D, store food environment interventions (13, 26%). Of the studies that assessed diet or health outcomes (36, 72%), 22 (61%) assessed dietary intakes; 16 (44%) sales/purchasing; and 8 (22%) weight-related outcomes. Store foods tended to contribute the greatest amount of dietary energy to the diets of Indigenous peoples and increased non-communicable disease risk as compared to traditional foods. Multi-pronged interventions appeared to have positive impacts on dietary behaviours, food purchasing and nutrition knowledge; promotion and nutrition education alone had more mixed effects. Of the nine studies which were found to have strong engagement with Indigenous populations, eight had moderate or high methodological quality. Eighteen studies (36%) did not mention any engagement with Indigenous populations.

Summary
The literature confirmed the importance of store foods to the total energy intake of the contemporary diets of Indigenous people, the gaps in accessing both retail food environments and traditional foods and the potential for both new dietary assessment research and retail food environment intervention strategies to better align with and privilege Indigenous Ways of Knowing.
