A mixed methods inquiry into the determinants of traditional food consumption among three Cree communities of Eeyou Istchee from an ecological perspective

Measurement of diet quality among First Nations peoples in Canada and associations with health: a scoping review

BACKGROUND

Given the increasing number and the diversity of dietary quality indices used for research, and the differences between settings, there is a need to identify valid indices of dietary quality in different contexts and populations and to identify their associations with health-related outcomes.

OBJECTIVES

The primary objective of this scoping review is to identify the tools used in determining dietary quality among First Nations and to describe the changes in diet. The second objective is to describe the associations identified in studies that have measured the relationship between health and dietary quality among First Nations; and the third objective is to identify factors associated with diet quality.

METHODS

PubMed, Embase, CINAHL, Global Health, and Web of Science were searched from inception to June 2021 and updated in February 2022. Articles were included if the research subjects were First Nations, or if articles reported disaggregated subset data for First Nations. Eligible studies focused on nutrition and diet and were published in English or French.

RESULTS

A total of 151 articles were included in the analysis. Studies used several indicators to measure if individuals adhered to dietary guidelines. Traditional food consumption was frequently used as an indicator of diet quality (n = 96). The consumption of store-bought foods was used as an indicator in 28 studies. Some studies used other diet quality indicators such as the Healthy Eating Index (n = 5) and ultra-processed food "NOVA" classification (n = 6). A trend for decreasing traditional food intake over time was apparent, alongside an increase in store-bought food intake. This trend was accompanied with declining health status, including the increased prevalence of overweight and obesity, diabetes, metabolic diseases, and dental caries.

CONCLUSION

This scoping review showed that diet quality among First Nations is improved when traditional foods are consumed. Reduced diet quality was associated with increased risk of noncommunicable diseases.

Indigenous food sovereignty assessment-A systematic literature review

AIMS

The aims of this systematic review were to (1) identify assessment approaches of Indigenous food sovereignty using the core domains of community ownership, inclusion of traditional food knowledge, inclusion/promotion of cultural foods and environmental/intervention sustainability, (2) describe Indigenous research methodologies when assessing Indigenous food sovereignty.

METHODS

Guided by Indigenous members of the research team, a systematic review across four databases (Medline, Embase, CINAHL and PsycINFO) was performed. Studies in any language from 1996 to 2021, that used one or more of the core domains (identified from a recent scoping review) of community ownership, inclusion of traditional food knowledge, inclusion/promotion of cultural foods and environmental/intervention sustainability were included.

RESULTS

From 20 062 records, after exclusion criteria were applied, 34 studies were included. Indigenous food sovereignty assessment approaches were mostly qualitative (n = 17) or mixed methods (n = 16), with interviews the most utilised (n = 29), followed by focus groups and meetings (n = 23) and validated frameworks (n = 7) as assessment tools. Indigenous food sovereignty assessment approaches were mostly around inclusion of traditional food knowledge (n = 21), or environmental/intervention sustainability (n = 15). Community-Based Participatory Research approaches were utilised across many studies (n = 26), with one-third utilising Indigenous methods of inquiry. Acknowledgement of data sovereignty (n = 6) or collaboration with Indigenous researchers (n = 4) was limited.

CONCLUSION

This review highlights Indigenous food sovereignty assessment approaches in the literature worldwide. It emphasises the importance of using Indigenous research methodologies in research conducted by or with Indigenous Peoples and acknowledges Indigenous communities should lead future research in this area.

Traditional Food Consumption in Andean Ecuador and Associated Consumer Characteristics, Shopping and Eating Habits

Traditional foods (TFs) hold increasing global relevance due to their potential to address health and dietary challenges. This study explores TF consumption and patterns in a middle-income country's general population. Using 2017 Ecuadorian highlands survey data, we identified four consumption clusters with distinct TF preferences. Chi-square tests identified variations in independent variables across clusters. Poisson regression models highlighted city, age, education, and food habits as independent predictors of TF-based clusters. Our findings broaden TF importance to nutrition beyond specific populations. Understanding consumption patterns and socioeconomic links supports nuanced public health strategies to tackle contemporary health, social equity, and sustainability issues.

A probabilistic hazard and risk assessment of exposure to metals and organohalogens associated with a traditional diet in the Indigenous communities of Eeyou Istchee (northern Quebec, Canada)

Hunting, trapping, and fishing are part of an Indigenous lifestyle in subarctic Canada. However, this lifestyle may be a route of exposure to contaminants and may pose a risk for the people who rely on a subsistence diet. Monte Carlo simulations for the chemical concentration of eight game species and one fish species were carried out by randomly sampling 10,000 samples from the contaminant measures for each species. We then calculated a probabilistic non-carcinogenic hazard quotient or carcinogenic risk values to estimate the human health risk of exposure to contaminants. Of the species examined, ducks were of concern for potential carcinogenic risk. There was a modeled probabilistic 95th-percentile risk associated with the consumption of ducks and polybrominated biphenyl (PBB) congener 153 in boys, women, and men (1.09 × 10-6, 1.57 × 10-6, and 2.17 × 10-6, respectively) and, to a lesser extent, with geese and polychlorinated biphenyl (PCB) congener 153 in men (1.19 × 10-6). Contaminant concentration in the intake rate (food consumption) for PBB congener 153 exposure risk was more important than that for PCB congener 153, where intake rate had greater relevance. The consumption of waterfowl may increase the exposure to organohalogens; however, there are health and wellness benefits associated with the harvesting and consumption of subsistence foods that must also be considered. We recommend follow-up species-specific studies focused on ducks to clarify and elucidate the results in the present study.

Indigenous Foods to Address Malnutrition: An Inquiry into the Diets and Nutritional Status of Women in the Indigenous Community of Munda Tribes of Jharkhand, India

Background

Indigenous people globally experience poor nutrition outcomes, with women facing the greater burden. Munda, a predominant tribe in Jharkhand, India, live in a biodiverse food environment but yet have high levels of malnutrition.

Objectives

To assess diets and the nutritional status of Munda tribal women and explore associations with their Indigenous food consumption, dietary diversity, and socioeconomic and demographic profiles.

Methods

A cross-sectional study with a longitudinal component to capture seasonal dietary intake was conducted in 11 villages of the Khunti district, Jharkhand. Household surveys and FFQs, supplemented with 2-d 24-h dietary recall and anthropometric assessments on 1 randomly selected woman per household were conducted.

Results

Limited access to diverse foods from a natural food environment (Food Accessed Diversity Index score of 0.3 ± 0.3) was observed. More than 90% women in both seasons had usual nutrient intakes below the estimated average requirements for all nutrients except protein and vitamin C; 35.5% of women were underweight. The mean Minimum Dietary Diversity Score among women (MDDS) was low [2.6 ± 0.6 in wet monsoon; 3 ± 0.7 in winters (acceptable ≥5)]. Higher MDDS contributed to higher usual nutrient intakes (P <0.001). Indigenous food intakes in both seasons (wet monsoon and winter) were low, e.g. Indigenous green leafy vegetables [10.5 and 27.8% of the recommended dietary intake (RDI), respectively], other vegetables (5.2% and 7.8% of RDI, respectively), and fruits (5.8 and 22.8% of RDI, respectively). Despite low intakes, the Indigenous food consumption score was positively associated with usual intake of vitamin A, riboflavin, vitamin C, pyridoxine, and calcium (P < 0.05) in the wet monsoon and thiamine, riboflavin, and zinc (P < 0.001) in winters. After adjusting for covariates, Indigenous food consumption was associated with a higher usual intake of vitamin A (P  < 0.001) in the wet monsoon season.

Conclusion

Contextual food-based interventions promoting Indigenous foods and increasing dietary diversity have the potential to address malnutrition in Munda women.

First Nations Peoples' Eating and Physical Activity Behaviors in Urban Areas: A Mixed-Methods Approach

The dietary transition from traditional to commercial foods and a decrease in physical activity (PA) have impacted the health of the First Nations people of Quebec (Canada), resulting in many suffering from multiple chronic diseases. This study had two objectives: (1) to examine eating and PA behaviors among First Nations peoples in urban areas and (2) to explore the associated health representations. To achieve these objectives, a mixed-methods approach, including a questionnaire (n = 32) and a semi-structured interview (n = 14), was used to explore the participants' lifestyle profiles and health experiences. The questionnaire focused on the eating and PA behaviors of First Nations people and their underlying motivations. At the same time, the interviews investigated their health views on diet and PA behaviors based on the conceptual framework of health and its determinants. According to the participants, health is the autonomy to live without pain by maintaining a balance between physical and psychological aspects, eating healthy and exercising. Family and work influence participants' PA and eating behaviors. Exploring First Nations people's beliefs and perceptions and the motivations underlying their health behaviors could help encourage the maintenance of a healthy lifestyle despite multiple chronic health conditions.

Exploring the environmental determinants of food choice among Haudenosaunee female youth

Background

Research on Indigenous food literacy within Canada has been focused on northern and remote communities despite the fact there are considerable and unique barriers to food access, availability, and utilization in southern Indigenous communities. Food insecurity is also a prevalent issue among Indigenous Peoples living in these more populous regions. Study objectives included investigating the determinants of food choice among youth, along with perceived opportunities that would improve food environments individually and at the community level.

Methods

This community-based study used Photovoice to explore the perceptions and experiences of traditional foods and the determinants of food choice among youth in the community of Six Nations of the Grand River. Participants took photos of their local food environments, including where foods were acquired, consumed, prepared, or shared, and participated in semi-structured interviews to share the stories behind these images. Thematic analysis was used to identify patterns in participants’ photos and interview content.

Results

Environmental factors were found to influence participants’ traditional and everyday food choices. Built, social, economic and ecological environments were described by the youth as distinct yet inter-related determinants that converge to influence individual food choice. Built environments had a notable impact on food choice, most notably at home and in school settings. Home and family were found to be facilitators of meal consistency and healthy food choices across participants. The social environment including participants’ relationships with their peers and community friends was often a barrier to healthy food choices. Eating at fast food outlets was a common social activity. The economic environment included cost deterrents associated with food choices and regular meals. The ecological environment was less of an influence and impacted the seasonal consumption of traditional and other locally harvested foods.

Conclusions

Overall, the study findings have generated important knowledge regarding food environments and literacy and serves as a unique example of how to explore the traditional and everyday food experiences of Indigenous youth. Recommendations will inform the development of new as well as existing initiatives and resources to enhance the holistic wellbeing of youth and the broader community.

Effects of Speciation, Cooking and Changes in Bioaccessibility on Methylmercury Exposure Assessment for Contrasting Diets of Fish and Marine Mammals

Uptake of the neurotoxicant monomethylmercury (MeHg) from fish and marine mammals continues to present a public health concern in Canada and elsewhere. However, fish and marine mammals are key diet items contributing to food security for some Indigenous populations in Canada. Mercury (Hg) exposure is estimated assuming that 100% of Hg is methylated, that 100% will be absorbed by the consumer and that cooking does not affect MeHg concentrations. Some of these assumptions do not correspond to our current state of knowledge. The aim of this study was to assess the impact of additional variables on Hg exposure equation using probabilistic risk analysis. New variables tested were (1) the proportion of methylated Hg compared to total Hg (pMeHg, %), (2) the relative absorption factor (RAF, %) expressed as bioaccessibility and (3) the mass loss factor (MLF, unitless) that represents the loss of moisture during cooking, known to increase MeHg concentration in fish and mammals. For the new variables, data from literature were used in order to set point estimate values that were further used in the probabilistic risk analysis. Modelling results for both fish and marine mammals indicate that adding these new variables significantly influenced estimates of MeHg exposure (Mood's median test, p < 0.05). This study highlights that the evaluation of exposure to MeHg is sensitive to pMeHg, RAF and MLF, and the inclusion of these variables in risk assessment should be considered with care. Further research is needed to provide better food-dependent, population-specific estimates of RAF and MLF before formal inclusion in exposure estimates.

"It's all interconnected… like a spider web": a qualitative study of the meanings of food and healthy eating in an Indigenous community

Canadian Indigenous populations are disproportionately affected by rising rates of diet-related chronic disease and have been experiencing rapid lifestyle changes affecting diet. In recognition of these issues, this study aimed to obtain greater understanding of attitudes and meanings around healthy eating in a semi-remote community in Eeyou Istchee. A qualitative study design used semi-structured interviews and observational field notes to explore local accounts of food and health. Two distinct versions of “healthy eating” were identified: one relating to traditional food and preparation methods; the other reflecting medicalised accounts of illness and diagnosed conditions. The latter links with “southern” modes of accessing and preparing food, demonstrating local capacity to adapt to the rapid changes in body, lifestyle and environment being experienced. New connections, associating non-native ways with traditional practices, are being formed where traditional ways of living on the land have been severed. These local accounts show how people are continually negotiating different constructs of “healthy eating.” These findings expand current understandings of the context of food and healthy eating in Eeyou Istchee, emphasising present-day and historical experiences of the land. Future research and diet-related health interventions must continue to acknowledge and incorporate local understandings of health to help address the broader socio-political factors that shape Indigenous lifestyles, environments and health.

Exploring the Perceptions of and Experiences with Traditional Foods among First Nations Female Youth: A Participatory Photovoice Study

Traditional foods contribute to the health and well-being of Indigenous Peoples. Many Indigenous Peoples within Canada have expressed a desire to consume more traditional foods; however, there are a number of barriers to doing so. Southern and urban communities face unique challenges associated with traditional food consumption. To address these concerns and build on community interests in a Haudenosaunee community in Southern Ontario, a participatory research project was initiated. This community-based study utilized Photovoice methodology to explore the perceptions of and experiences with traditional foods among local youth. Participants ranging in age from 15-22 (n = 5) took photos of their local food environments, including locations where foods were acquired, consumed, prepared, or shared during two seasons of the year. Semi-structured interviews were conducted to collect participants' stories behind 8-10 self-selected images. A thematic analysis was subsequently utilized to identify patterns and themes illustrated by the photos and interview content. The youth conveyed contextual understandings of traditional foods and a preference for these items, despite their limited consumption, preparation or harvesting of these foods. The youth also identified the important influence of families and communities on their individual perceptions and experiences with traditional foods. Recommendations to reduce barriers to traditional food choices among youth are made.

Exploring First Nation Elder Women's Relationships with Food from Social, Ecological, and Historical Perspectives

BACKGROUND

The ongoing negative health effects of colonization have disproportionately affected Indigenous women, who are disproportionately affected by diabetes, food insecurity, and undernutrition. Indigenous women also perceive their health less positively than men do. This article draws theoretically from the socio-ecological model to explore health inequalities experienced by Indigenous women associated with the intergenerational effects of the residential school legacy, specifically related to food practices.

OBJECTIVES

Study objectives were to describe and compare the historical context of present-day urban and rural food environments, and explore the hypothesis that food insecurity may be associated with cultural loss resulting from the intergenerational trauma of residential schools in this region of southwestern Ontario, Canada.

METHODS

Framed by a larger community-based participatory study, life history interviews took place with 18 Elder women living on- and off-reserve in southwestern Ontario, Canada.

RESULTS

Women discussed painful circumstances of displacement from the land and social disconnection from families and communities. The 10 participants who were residential school survivors conveyed the intergenerational effects of loss, responsibility, lack of support, and an altered sense of identity as narratives of survival. Six women had moved away from their home communities, which created challenges to fully engage in local food procurement and sharing practices. These altered geographies present practical limitations, along with apparent mechanisms of social and cultural exclusion.

CONCLUSIONS

Research on Indigenous Peoples' food systems requires further analysis of the root causes of disparities in the context of societal and gender relations. Food sovereignty has been the domain of women, who have led movements aimed at both social and environmental justice. Unraveling the historical, social, and environmental determinants of Indigenous food knowledge will support and guide community and policy recommendations, highlighting the ongoing effects of residential schooling and other indirect examples of environmental dispossession that have disproportionately affected Indigenous women.

Optimisation modelling to improve the diets of First Nations individuals

We examined the feasibility of linear programming (LP) to develop diets that were economical, included traditional (cultural, non-market) foods and met the dietary reference intakes (DRI) in a Canadian Indigenous population. Diet optimisation using LP is a mathematical technique that can develop food-based dietary guidelines for healthy eating in Indigenous populations where food insecurity, availability and cost are important considerations. It is a means of developing nutritionally optimal food combinations that are based on economical and culture-specific foods. Observed food consumption data were derived using 24-h food recalls from the First Nations Food, Nutrition and Environment Study. The LP models were constructed to develop diets meeting DRI, cost and food constraints. Achieving the recommended food intake was not feasible in a model meeting all nutrient requirements. Models that met most nutrient requirements at reduced cost were designed for men and women, separately. In women, it was necessary to increase energy intake to meet most nutrient requirements. Nutrient requirements could not be met for fibre, linoleic and linolenic acids, vitamin D, Ca and K in both sexes, P in women, and Mg and vitamin A in men. Using LP to develop optimal diets for First Nations people, we found simultaneous achievement of all DRI was difficult, suggesting that supplementation might be necessary which goes against recommendations for individuals to meet their nutrient needs through healthy eating patterns. Additionally, to make diets feasible, programmes to reduce market food costs and to support First Nations people in traditional food harvesting are recommended.

Factors associated with the intake of traditional foods in the Eeyou Istchee (Cree) of northern Quebec include age, speaking the Cree language and food sovereignty indicators

The Eeyouch are a First Nations (Cree) population that live above 49.6°N latitude in Eeyou Istchee in northern Quebec. Eeyouch rely on traditional foods (TF) hunted, fished or gathered from the land. The overarching aim of this study was to achieve an understanding of the factors associated with TF intake among Eeyouch. Data were from 465 women and 330 men who participated in the Nituuchischaayihtitaau Aschii Multi-Community Environment-and-Health (E&H) study. The relationship between TF consumption and dietary, health, sociodemographic and food sovereignty (i.e. being a hunter or receiving Income Security to hunt, trap or fish) variables was examined using linear and logistic regression. Analyses were stratified by sex because of the male/female discrepancy in being a hunter. Among respondents, almost all (99.7%) consumed TF, 51% were hunters and 10% received Income Security. Higher intake of TF was associated with lower consumption of less nutritious ultra-processed products (UPP). In women, TF intake increased with age, hunting and receiving Income Security, but decreased with high school education. In men, TF intake increased with age and speaking only Cree at home. The findings suggest that increased food sovereignty would result in improved diet quality among Eeyouch through increased TF intake and decreased UPP intake.

Risk assessment of dietary lead exposure among First Nations people living on-reserve in Ontario, Canada using a total diet study and a probabilistic approach

Indigenous peoples have elevated risk of lead (Pb) exposure as hunted traditional food can be contaminated with lead-containing ammunition. Recent scientific consensus states that there is no threshold level for Pb exposure. The objective of this study was to estimate dietary exposure to Pb among First Nations living on-reserve in the province of Ontario, Canada. A total diet study was constructed based on a 24-h recall and Pb concentrations for traditional foods from the First Nations Food, Nutrition, and Environment Study (FNFNES) and Pb concentrations in market foods from Health Canada. A probabilistic assessment of annual and seasonal traditional food consumption was conducted. Results indicate that traditional foods, particularly moose and deer meat. are the primary source of dietary Pb intake (73%), despite providing only 1.8% of the average caloric intake. The average dietary Pb exposure (0.21μg/kg/d) in the First Nations population in Ontario was 1.7 times higher than the dietary Pb exposure in the general Canadian population. Pb intake was associated with an estimated average increase in systolic blood pressure of 1.2mmHg. These results indicate that consumption of foods hunted with Pb containing ammunition and shot puts the population at elevated risk of Pb toxicity.

A total diet study and probabilistic assessment risk assessment of dietary mercury exposure among First Nations living on-reserve in Ontario, Canada

Methyl Mercury (MeHg) exposure is a global environmental health concern. Indigenous peoples around the world are susceptible to MeHg exposure from often higher fish consumption compared to general populations. The objective of this study was to estimate dietary exposure to methylmercury (MeHg) among First Nations living on-reserve in the province of Ontario, Canada. A total diet study was constructed based on a 24-h recall from the First Nations Food, Nutrition, and Environment Study (FNFNES), and measured contaminant concentrations from Health Canada for market foods, and FNFNES for traditional foods. A probabilistic assessment of annual and seasonal traditional food consumptions was conducted for 1429 adult participants. Results were compared to exposures in the general Canadian population and reference values from Health Canada for adults and women of childbearing age (ages 19-50). Results indicated traditional foods to be the primary contributor to the dietary total MeHg intake (72%). The average dietary total MeHg exposure in the First Nations population in Ontario (0.039μg/kg/d) was 1.6 times higher than the general Canadian population; however, the majority (97.8%) of the population was below the reference values. Mercury concentrations in participants' hair samples (n = 744) ranged from 0.03 to 13.54µg/g, with an average of 0.64µg/g (geometric average of 0.27µg/g). Less than 1% of the population had a hair mercury value above the 6µg/g level, and 1.3% of women of child bearing age had values greater than 2µg/g. Fish species contributing to the MeHg intake included pickerel-walleye, pike, perch and trout. Only 7.9% of the population met the recommended fish consumption rate of two, 3.5oz servings per week from the American Heart Association. Therefore, consumption of lower trophic level fish can be promoted to provide the maximum nutritional benefit with minimal risk of MeHg exposure.

Facilitators and Barriers to Traditional Food Consumption in the Cree Community of Mistissini, Northern Quebec

To identify barriers to traditional food consumption and factors that facilitate it among the Cree community of Mistissini, a series of four focus groups was conducted with a total of twenty-three people. Two ecological models were created, one for facilitating factors and a second for obstacles, illustrating the role of numerous interconnected influences of traditional food consumption. Environmental impact project, laws and regulation, local businesses, traditional knowledge, youth influence, employment status, and nonconvenience of traditional food were named among numerous factors influencing traditional food consumption. The findings of this study can be used by political and public health organizations to promote traditional food where more emphasis should be invested in community and environmental strategies.
