The Retail Food Sector and Indigenous Peoples in High-Income Countries: A Systematic Scoping Review

Indigenous Peoples in high-income countries experience higher burdens of food insecurity, obesity, and diet-related health conditions compared to national averages. The objective of this systematic scoping review is to synthesize information from the published literature on the methods/approaches, findings, and scope for research and interventions on the retail food sector servicing Indigenous Peoples in high-income countries. A structured literature search in two major international databases yielded 139 relevant peer-reviewed articles from nine countries. Most research was conducted in Oceania and North America, and in rural and remote regions. Several convergent issues were identified across global regions including limited grocery store availability/access, heightened exposure to unhealthy food environments, inadequate market food supplies (i.e., high prices, limited availability, and poor quality), and common underlying structural factors including socio-economic inequality and colonialism. A list of actions that can modify the nature and structure of retailing systems to enhance the availability, accessibility, and quality of healthful foods is identified. While continuing to (re)align research with community priorities, international collaboration may foster enhanced opportunities to strengthen the evidence base for policy and practice and contribute to the amelioration of diet quality and health at the population level.

The Retail Food Environment, Store Foods, and Diet and Health among Indigenous Populations: a Scoping Review

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. 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.

Leveraging Traditional Ecological Knowledge and Access to Nutrient-Rich Indigenous Foods to Help Achieve SDG 2: An Analysis of the Indigenous Foods of Sauria Paharias, a Vulnerable Tribal Community in Jharkhand, India

Indigenous food systems of traditional communities are potentially sustainable, have nutrient rich food sources and can enhance dietary diversity. Sauria Paharias, are one of the particularly vulnerable tribal groups of Jharkhand India, who despite residing in rich biodiverse environment and possessing traditional ecological knowledge, lag behind various health, and nutritional indicators. Our study explored their traditional ecological knowledge around indigenous foods (IFs), their routine consumption, access, and nutritive values. A cross-sectional mixed methods study was carried out in 18 villages of Godda district, Jharkhand. Free list of all IFs known to the community was developed using focus group discussions. This was followed by enumerating commonly consumed as well as little or historically used IFs. Following the taxonomic classification of these foods, their nutritive values were searched in literature or food samples were analyzed in accredited laboratories. Reasons for consumption and non-consumption of specific IFs were explored. The community was aware of a large number of IFs (n = 193) but only 50% of these were routinely consumed. Rest were either little used or historically consumed. About 47.6% IFs (n = 92) were identified using taxonomic classification; of which 87 IFs were classified based on their common names in secondary literature and five food items were collected, herbariums were prepared and identified. Nutritive values were documented for 84 IFs (this included both routinely consumed as well as little used); out of which 55 foods were found to have nutritive values in existing literature and 29 foods were analyzed in laboratory. Many of these IFs were rich in micronutrients like calcium, iron, zinc, folic acid, vitamin A, and vitamin C. Common reasons for preferences or non-consumption of specific IFs included taste, availability, access seasonality, opportunity cost of access and processing time. Promoting adequate intake of commonly accessed nutrient rich IFs and revival of little used IFs while addressing the causes of non-consumption and mainstreaming them into the daily diets could be an effective strategy to increase the intake of micronutrients. Policies focusing on incorporation of nutrient rich IFs into dietary diversification strategies and ongoing supplementary feeding programs can help address malnutrition in the community.

The adoption, implementation and maintenance of a school food policy in the Canadian Arctic: a retrospective case study

With increasing childhood obesity rates and type 2 diabetes developing in younger age groups, many schools have initiated policies to support healthy eating and active living. Policy interventions can influence not only health behaviours in students but can also impact these behaviours beyond the school walls into the community. We articulate a policy story that emerged during the data collection phase of a study focused on building knowledge and capacity to support healthy eating and active living policy options in a small hamlet located in the Canadian Arctic. The policy processes of a local school food policy to address unhealthy eating are discussed. Through 14 interviews, decision makers, policy influencers and health practitioners described a policy process, retrospectively, including facilitators and barriers to adopting and implementing policy. A number of key activities facilitated the successful policy implementation process and the building of a critical mass to support healthy eating and active living in the community. A key contextual factor in school food policies in the Arctic is the influence of traditional (country) foods. This study is the first to provide an in-depth examination of the implementation of a food policy in a Canadian Arctic school. Recommendations are offered to inform intervention research and guide a food policy implementation process in a school environment facing similar issues.

Local observations of climate change and impacts on traditional food security in two northern Aboriginal communities

OBJECTIVES

Our primary objective was to record participant observations of changes in the local environment, harvesting situations and traditional food species and to explore what impact these may have on traditional food.

STUDY DESIGN

A participatory study with 2 northern Aboriginal communities in Canada.

METHODS

Focus groups were conducted in both communities. Both specific and open-ended questions were asked, to gather information about the traditional food harvest and a qualitative analysis was conducted.

RESULTS

Members from both communities are witnessing variable changes in climate that are affecting their traditional food harvest. New species and changes in migration of species being observed by community members have the potential to affect the consumption of traditional food. Similarly, changes in water levels in and around harvesting areas are affecting access to harvest areas, which in turn affects the traditional food harvest.

CONCLUSIONS

Community members have been required to change their harvest mechanisms to adapt to changes in climate and ensure an adequate supply of traditional food. A strong commitment to programs that will ensure the protection of traditional food systems is necessary.

"We are not being heard": Aboriginal perspectives on traditional foods access and food security

Aboriginal peoples are among the most food insecure groups in Canada, yet their perspectives and knowledge are often sidelined in mainstream food security debates. In order to create food security for all, Aboriginal perspectives must be included in food security research and discourse. This project demonstrates a process in which Aboriginal and non-Aboriginal partners engaged in a culturally appropriate and respectful collaboration, assessing the challenges and barriers to traditional foods access in the urban environment of Vancouver, BC, Canada. The findings highlight local, national, and international actions required to increase access to traditional foods as a means of achieving food security for all people. The paper underscores the interconnectedness of local and global food security issues and highlights challenges as well as solutions with potential to improve food security of both Aboriginal and non-Aboriginal peoples alike.

Trends in Métis-related health research (1980-2009): identification of research gaps

OBJECTIVE

Several literature reviews have highlighted the under-representation of Métis in research regarding Aboriginal Peoples. However, to date, an in-depth examination of trends in Métis research has not been undertaken. This literature review aims to identify trends and gaps in Métis-related health/well-being research over the past three decades (1980-2009).

METHODS

Health, medical and social sciences literature databases including Cochrane, CINAHL, Embase, Pubmed, PyschInfo, and Web of Science were searched for Métis-relevant peer-reviewed articles published between 1980 and 2009 via two search strategies: 1) using the terms "Métis," "mixed-blood" or "half-breed," and 2) using a combination of terms: (Aboriginal OR Indigenous OR native OR "First Nation" OR Indian) and (mixed OR European OR Caucasian OR white) and "Canada". Articles pertaining to the health/well-being of Métis in Canada were retained, coded and analyzed by study type/design, gender-specificity, geography, research topic, the extent to which Métis-specific breakdown of findings was provided, and methodological quality relating to validity and reliability of the study.

RESULTS

Noteworthy strengths in Métis research were observed, including increasing attention to chronic diseases, diet/nutrition/physical activity, and maternal and child health; a trend towards increased presentation of Métis-specific results among pan-Aboriginal studies, and female-specific and qualitative studies; and an equitable focus on urban and rural areas. Gaps were seen in research related to environment/toxicology, genetics, health delivery/programming/policy, injury, mental health (MH)/addictions, social determinants of health, and violence/crime. In addition, a dearth of male-specific research was identified. Also, most articles were cross-sectional in design. Finally, despite an increase in Métis-related articles over the past three decades, a large proportion of articles remained pan-Aboriginal in nature and did not provide a Métis-specific breakdown of findings. With respect to methodological quality, nearly two thirds of all studies were of strong or moderate quality (cross-sectional studies), good quality (cohort/case-control studies) or acceptable quality (qualitative and mixed methods studies).

CONCLUSION

Several gaps exist in Métis-related health/well-being research with respect to study type/design, gender-specificity, research topics, presentation of Métis-specific findings, and methodological quality. In addition to specific gaps, the overall limited number of research articles/studies needs to be recognized. These deficiencies could be alleviated by increasing targeted funding and support for Métis-related research, and removing barriers to Métis-specific research. Addressing gaps in Métis health research will enable identification of appropriate targets for intervention and, subsequently, design, development and evaluation of interventions to address Métis health disparities and their determinants.

Conceptualizing food security or aboriginal people in Canada

Food insecurity is an urgent public health issue for Aboriginal people in Canada because of high rates of poverty; the effects of global climate change and environmental pollution on traditional food systems; and high rates of diet-related diseases. However, to date, public health has operated with conceptualizations of food security that were developed in non-Aboriginal contexts; they do not take full account of the traditional food practices of Aboriginal people or Aboriginal conceptualizations of food security. In this paper, I argue that there are unique food security considerations for Aboriginal people related to the harvesting, sharing and consumption of country or traditional foods, which impact the four pillars of food security: access, availability, supply and utilization. Thus food security conceptualizations, policies, and programs for Aboriginal people must consider both the market food system and traditional food system. Given the centrality of traditional food practices to cultural health and survival, I propose that cultural food security is an additional level of food security beyond individual, household and community levels. Conceptualizations of food security for Aboriginal people will be incomplete without qualitative research to understand Aboriginal perspectives; such research must take account of the diversity of Aboriginal people.

Human health implications of environmental contaminants in Arctic Canada: A review

The objectives of this paper are to: assess the impact of exposure to current levels of environmental contaminants in the Canadian Arctic on human health; identify the data and knowledge gaps that need to be filled by future human health research and monitoring; examine how these issues have changed since our first assessment [Van Oostdam, J., Gilman, A., Dewailly, E., Usher, P., Wheatley, B., Kuhnlein, H. et al., 1999. Human health implications of environmental contaminants in Arctic Canada: a review. Sci Total Environ 230, 1-82]. The primary exposure pathway for contaminants for various organochlorines (OCs) and toxic metals is through the traditional northern diet. Exposures tend to be higher in the eastern than the western Canadian Arctic. In recent dietary surveys among five Inuit regions, mean intakes by 20- to 40-year-old adults in Baffin, Kivalliq and Inuvialuit communities exceeded the provisional tolerable daily intakes (pTDIs) for the OCs, chlordane and toxaphene. The most recent findings in NWT and Nunavut indicate that almost half of the blood samples from Inuit mothers exceeded the level of concern value of 5 microg/L for PCBs, but none exceeded the action level of 100 microg/L. For Dene/Métis and Caucasians of the Northwest Territories exposure to OCs are mostly below this level of concern. Based on the exceedances of the pTDI and of various blood guidelines, mercury and to a lesser extent lead (from the use of lead shot in hunting game) are also concerns among Arctic peoples. The developing foetus is likely to be more sensitive to the effects of OCs and metals than adults, and is the age groups of greatest risk in the Arctic. Studies of infant development in Nunavik have linked deficits in immune function, an increase in childhood respiratory infections and birth weight to prenatal exposure to OCs. Balancing the risks and benefits of a diet of country foods is very difficult. The nutritional benefits of country food and its contribution to the total diet are substantial. Country food contributes significantly more protein, iron and zinc to the diets of consumers than southern/market foods. The increase in obesity, diabetes and cardiovascular disease has been linked to a shift away from a country food diet and a less active lifestyle. These foods are an integral component of good health among Aboriginal peoples. The social, cultural, spiritual, nutritional and economic benefits of these foods must be considered in concert with the risks of exposure to environmental contaminants through their exposure. Consequently, the contamination of country food raises problems which go far beyond the usual confines of public health and cannot be resolved simply by risk-based health advisories or food substitutions alone. All decisions should involve the community and consider many aspects of socio-cultural stability to arrive at a decision that will be the most protective and least detrimental to the communities.

Estimation of traditional food intake in indigenous communities in Denendeh and the Yukon

OBJECTIVES

Chronic non-communicable diseases related to excessive or unbalanced dietary intakes are on the rise among some Indigenous populations in Canada. Nutritional problems of Indigenous peoples arise in the transition from a traditional diet to a market diet characterized by highly processed foods with reduced nutrient density. This study aimed at assessing traditional food intake of Indigenous people in 18 communities.

STUDY DESIGN

This study was cross-sectional with a sample size of 1,356.

METHODS

This study used food frequency and 24-hour recall questionnaires to quantify traditional food intake in 18 communities in the McKenzie basin of the Northwest Territories (Denendeh and the Yukon).

RESULTS

Typical daily intakes of groups of traditional food items were generated and intake of an extensive list of traditional food detailed for adult men and women. Per capita intake of traditional food items was also calculated.

CONCLUSION

Reliance on traditional food intake is still high in Denendeh, as well as in the Yukon. The detailed description of the traditional food system presented here allows an accurate identification of the contribution of traditional food items to nutrient and contaminant intake by Indigenous people for future studies.

Content analysis: review of methods and their applications in nutrition education

Content analysis is a set of qualitative and quantitative methods for collecting and analyzing data from verbal, print, or electronic communication with numerous applications in nutrition education research. Textual information from interviews, focus groups, and open-ended survey questions can be evaluated using content analysis. Selection of method(s) depends on the type(s) and length of material to be analyzed, results desired, and researchers' preferences and technological capabilities. This article reviews options available to content analysts--from manual to fully computerized. Overcoming the challenges inherent in using these methodologies is recommended because of their usefulness in the information-based messaging discipline of nutrition education.
