Can common dietary assessment methods be better designed to capture the nutritional contribution of neglected, forest, and wild foods to diets? Front Nutr 2023; 10:1186707.

Abstract
Food systems are the primary cause of biodiversity loss globally. Biodiversity and specifically, the role that wild, forest and neglected and underutilised species (NUS) foods might play in diet quality is gaining increased attention. The narrow focus on producing affordable staples for dietary energy has contributed to largely homogenous and unhealthy diets. To date, evidence to quantify the nutritional contribution of these biodiverse foods is limited. A scoping review was conducted to document the methods used to quantify the contribution of wild, forest and NUS foods. We found 37 relevant articles from 22 different countries, mainly from Africa (45%), the Americas (19%), and Asia (10%). There were 114 different classifications used for the foods, 73% of these were specifically related to wild or forest foods. Most dietary assessments were completed using a single day qualitative or quantitative 24 h open recall (n = 23), or a food frequency questionnaire (n = 12). There were 18 different diet related indicators used, mainly nutrient adequacy (n = 9) and dietary diversity scores (n = 9). Often, no specific nutritionally validated diet metric was used. There were 16 studies that presented results (semi) quantitatively to measure the contribution of wild, forest or NUS foods to dietary intakes. Of these, 38% were aggregated together with broader classifications of 'traditional' or 'local' foods, without definitions provided meaning it was not possible to determine if or to what extend wild, forest of NUS foods were included (or not). In almost all studies there was insufficient detail on the magnitude of the associations between wild, forest or NUS foods and dietary energy or nutrient intakes or the (qualitative) diet recall methodologies that were used inhibited the quantification of the contribution of these foods to diets. A set of six recommendations are put forward to strengthen the evidence on the contribution of wild, NUS, and forest foods to human diets.

Abstract
BackgroundThe National Inuit Strategy on Research focuses on advancing Inuit governance in research, increasing ownership over data and building capacity. Responding to this call for Inuit self-determination in research, academic researchers should consider cultural safety in research and ways to promote Inuit-led methods.MethodsThis scoping review collated academic literature on public health research in Inuit communities in Canada between 2010 and 2022. A critical assessment of methods used in public health research in Inuit communities examined cultural safety and the use of Inuit-attuned methods. Descriptive and analytical data were summarised in tables and figures. Knowledge user engagement in the research process was analysed with thematic analysis.Results356 articles met the inclusion criteria. Much of the published research was in nutrition and mental health, and few initiatives reported translation into promotion programmes. Almost all published research was disease or deficit focused and based on a biomedical paradigm, especially in toxicology, maternal health and chronic diseases. Recent years saw an increased number of participatory studies using a decolonial lens and focusing on resilience. While some qualitative research referred to Inuit methodologies and engaged communities in the research process, most quantitative research was not culturally safe. Overall, community engagement remained in early stages of co-designing research protocols and interventions. Discussion on governance and data ownership was limited. Recent years saw emerging discussions on these issues. Knowledge user capacity-building was limited to brief training on conventional data collection methods.ConclusionsThe last decade of published public health research has not responded to the National Inuit Strategy on Research. Participatory research is gaining ground, but has not reached its full potential. A shift from biomedical to decolonised methods is slowly taking place, and public health researchers who have not yet embraced this paradigm shift should do so.

Exposure to a Multilevel, Multicomponent Obesity Prevention Intervention (OPREVENT2) in Rural Native American Communities: Variability and Association with Change in Diet Quality. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182212128.

Abstract
The OPREVENT2 obesity prevention trial was a multilevel multicomponent (MLMC) intervention implemented in rural Native American communities in the Midwest and Southwest U.S. Intervention components were delivered through local food stores, worksites, schools, community action coalitions, and by social and community media. Due to the complex nature of MLMC intervention trials, it is useful to assess participants’ exposure to each component of the intervention in order to assess impact. In this paper, we present a detailed methodology for evaluating participant exposure to MLMC intervention, and we explore how exposure to the OPREVENT2 trial impacted participant diet quality. There were no significant differences in total exposure score by age group, sex, or geographic region, but exposure to sub-components of the intervention differed significantly by age group, sex, and geographical region. Participants with the highest overall exposure scores showed significantly more improvement in diet quality from baseline to follow up compared to those who were least exposed to the intervention. Improved diet quality was also significantly positively associated with several exposure sub-components. While evaluating exposure to an entire MLMC intervention is complex and imperfect, it can provide useful insight into an intervention’s impact on key outcome measures, and it can help identify which components of the intervention were most effective.

Abstract
Food Frequency Questionnaires (FFQ) can be used to document food consumption and to estimate the intake of contaminants for Indigenous populations. The objective of this project was to refine and implement an FFQ to estimate the consumption of traditional locally harvested foods for Dene/Métis in the Northwest Territories, Canada. The strategy consisted of: 1) refining the FFQ through three focus groups and, 2) implementing the FFQ in Indigenous communities. Participants were asked to complete the FFQ using an iPad to document the types of traditional foods consumed over the past 12 months, as well as the consumption frequency, the portion size, and the preparation methods. Focus groups supported the refinement of the FFQ on the format, the list of foods, and the preparation methods listed in the questionnaire. The refined FFQ was then implemented with participants (n = 237). Findings indicated that the traditional foods most frequently consumed were moose, whitefish and lake trout. Participants who consumed fish and land animals reported, on average, a portion size for one serving of between 126 and 143 g, depending on age and sex. These findings increase knowledge of the current traditional food consumption of Dene/Métis communities and will support the assessment of contaminant exposure.

Abstract
OBJECTIVE Game bird consumption is an important part of the diet of Indigenous populations in Canada and, as part of country food consumption, is associated with improved nutritional status. The objective of this project was to document the consumption of game birds for Dene First Nations in the Northwest Territories (NWT), Canada. DESIGN Participants were invited to complete a FFQ using an iPad to document the types of country foods consumed, as well as consumption frequency and preparation methods, including thirteen types of game birds. SETTING The project was implemented in nine communities in the Dehcho and Sahtú regions of the NWT, Canada. PARTICIPANTS A total of 237 children and adult participants from Dene First Nations in the Mackenzie Valley region of the NWT took part in the current study. RESULTS FFQ findings indicated that game birds were frequently consumed in both Dehcho and Sahtú communities. Canada goose and mallard were found to be consumed by the largest number of participants. Five different species (including Canada goose and mallard) were found to be consumed by at least 25 % of participants over the last year. When consuming game birds, most participants reported consuming the meat as well as most, if not all, other parts of the bird. CONCLUSIONS Differences were observed since the last country food assessment in the 1990s in the same regions. These findings increase knowledge of the current Dene diet patterns and support the understanding of diet transition.

Abstract
OBJECTIVE To identify psychosocial and household environmental factors related to diet quality among Native Americans (NA). DESIGN Analysis of baseline data from a community-randomized obesity prevention trial. SETTING Six rural NA communities in the Midwest and the Southwestern US. PARTICIPANTS A total of 580 tribal members, aged 18-75 years old (mean 45 years), 74% female, self-identified as the main household food purchaser. VARIABLES MEASURED Diet quality (Healthy Eating Index-2015 [HEI]) was derived from a semiquantitative food frequency questionnaire. Sociodemographic, psychosocial, and home food environment factors were assessed via interviewer-administered questionnaires. ANALYSIS One-way ANOVA, linear regression models, and 2-tailed t tests compared HEI scores among sociodemographic categories. Multiple linear regression models assessed the relationship between psychosocial factors, home food environment, and HEI. RESULTS Prevalence of obesity was 59%. Mean HEI-2015 score was 49.3 (SD = 8.1). Average HEI scores were 3.0 points lower in smokers than nonsmokers (P < 0.001), and 2.2 points higher in females than males (P < 0.01). Higher self-efficacy (β = 0.97; P < 0.001) and healthier eating intentions (β = 0.78; P < 0.001) were positively associated with HEI. Healthier household food patterns score was associated with higher HEI (β = 0.48; P < 0.01). CONCLUSIONS AND IMPLICATIONS Psychosocial factors were associated with diet quality, a finding that supports the use of social-cognitive intervention approaches in rural NA communities in the Midwest and Southwest, and warrants evaluation in other locations. There remains a need to elucidate the association between the Food Distribution Program on Indian Reservations and diet quality.

Abstract
The traditional diets of Indigenous Peoples globally have undergone a major transition due to settler colonialism. This systematic review aims to provide a perspective of traditional food intake of Indigenous populations in high-income settler-colonized countries. For inclusion, studies reported the primary outcome of interest-traditional food contribution to total energy intake (% of energy)-and occurred in Canada, the United States (including Hawaii and Alaska), New Zealand, Australia, and/or Scandinavian countries. Primary outcome data were reported and organized by date of data collection by country. Forty-nine articles published between 1987 and 2019 were identified. Wide variation in contribution of traditional food to energy was reported. A trend for decreasing traditional food energy intake over time was apparent; however, heterogeneity in study populations and dietary assessment methods limited conclusive evaluation of this. This review may inform cross-sectoral policy to protect the sustainable utilization of traditional food for Indigenous Peoples.

Abstract
PURPOSE OF REVIEW The Inuit population living in North Canada is facing a drastic change in lifestyle, which has brought about a dramatic nutrition transition characterized by a decrease in the traditional foods consumption and an increasing reliance on processed, store-bought foods. This rapid dietary shift leads to a significant public health concern, as wild-harvested country foods are rich in many micronutrients including vitamins, trace elements and minerals while the most frequently eaten Western foods mainly provide energy, fat, carbohydrates and sodium. This review addresses the emerging strategies to tackle food insecurity in this population. RECENT FINDINGS Recent studies indicate that diets with a higher fraction of traditional foods (and a lower fraction of ultra-processed foods) exhibit a better Healthy Eating Index. This provides a basis to develop new dietary policies anchored in contemporary food realities. SUMMARY In Northern remote communities, improving food security requires holistic approaches. A mixed strategy that targets the revitalization of traditional foods systems and local food production initiatives seems the most promising strategy, to meet the dietary needs in terms of micronutrients, with respect to the cultural identity of local populations.

Abstract
ABSTRACT
Background
American Indian (AI) have the highest rates of diet-related chronic diseases in the country. Yet, the relation between dietary patterns and chronic diseases in this population has not been well explored.
Objective
We aimed to characterize common dietary patterns among adults from 6 AI communities (N = 580) and assess their relation with BMI, percentage body fat, waist-to-hip ratio, hypertension, and self-reported type 2 diabetes and cardiovascular disease.
Methods
We conducted a baseline assessment of an obesity prevention study (N = 580). Dietary intake data were collected using a modified Block FFQ. Exploratory factor analysis was used to characterize dietary patterns. We used multivariate linear and logistic regression analyses to assess associations between dietary patterns and health outcomes, controlling for age, sex, employment status, smoking status, geographic region, and energy intake.
Results
Five dietary patterns, explaining 81.8% of variance in reported food consumption, were identified: “meat and fried foods,” “processed foods,” “fruits and vegetables,” “sugary snacks,” and “meat alternatives and high-protein foods.” “Those with higher consumption of “meat and fried foods” were associated with higher mean waist-to-hip ratio (0.03; 95% CI: 0.01, 0.04), higher mean BMI (2.45 kg/m2; 95% CI: 0.83, 4.07), and increased odds of being overweight or obese (OR: 2.63; 95% CI: 1.10, 6.31) compared to those with lower consumption of “meat and fried foods.” Higher consumption of “processed foods” was associated with increased odds of self-reported type 2 diabetes (OR: 3.41; 95% CI: 1.31, 8.90). No protective effect of consumption of “fruits and vegetables” was observed, although average consumption was below national recommendation levels.
Conclusions
AI dietary patterns corroborate nutritional concerns previously reported among AI populations. Future interventions should discourage overconsumption of meat, fried foods, and processed foods, and promote consumption of fruits and vegetables to reduce chronic disease burden in this population.

Abstract
OBJECTIVE To explore availability, variety and frequency consumption of traditional foods and their role in alleviating food insecurity in remote Aboriginal Australia. METHODS Availability was assessed through repeated semi-structured interviews and consumption via a survey. Quantitative data were described and qualitative data classified. RESULTS Aboriginal and non-Indigenous key informants (n=30 in 2013; n=19 in 2014) from 20 Northern Territory (NT) communities participated in interviews. Aboriginal primary household shoppers (n=73 in 2014) in five of these communities participated in a survey. Traditional foods were reported to be available year-round in all 20 communities. Most participants (89%) reported consuming a variety of traditional foods at least fortnightly and 71% at least weekly. Seventy-six per cent reported being food insecure, with 40% obtaining traditional food during these times. CONCLUSIONS Traditional food is consumed frequently by Aboriginal people living in remote NT. Implications for public health: Quantifying dietary contribution of traditional food would complement estimated population dietary intake. It would contribute evidence of nutrition transition and differences in intakes across age groups and inform dietary, environmental and social interventions and policy. Designing and conducting assessment of traditional food intake in conjunction with Aboriginal leaders warrants consideration.

Abstract
For indigenous Arctic Canadians, traditional food consumption represents a key source of nutrients and environmental contaminants. Particularly, ingestion of marine mammal blubber and meat may lead to persistent organic pollutant levels and mercury intakes that exceed regulatory thresholds for sensitive populations. We investigated whether temporary adjustments to the consumption of traditional food derived from marine mammals appreciably impacted contaminant exposure and nutrient intakes among indigenous women of childbearing age. Such adjustments can be motivated by the desire to lower contaminant exposure or to increase nutrition, or by the diminishing availability of other traditional food sources. We combined the contaminant fate and transport model GloboPOP with the food chain bioaccumulation model ACC-Human Arctic to simulate polychlorinated biphenyl exposures in female 2007-08 Inuit Health Survey participants. We also calculated daily mercury and nutrient intake rates. Our results suggest that a temporary decrease in marine mammal consumption is largely ineffective at reducing exposure to polychlorinated biphenyls, because of their long elimination half-lives. In contrast, substitution of marine mammals was highly efficient at reducing mercury intake, but also appreciably lowered intakes of iron, manganese, selenium, and ω-3 polyunsaturated fatty acids. The impact of increasing intake of traditional food derived from marine mammals during childbearing age greatly depended on baseline consumption rates; replacement is ill-advised for those who already consume a lot of traditional food due to greater polychlorinated biphenyl and mercury exposures, while replacement was potentially beneficial for those with very limited marine mammal consumption due to increased nutrient intakes. Our calculations primarily suggest that considering baseline traditional food intake rates is critical to devising reproductive dietary adjustment strategies that maximize nutrient intake while minimizing environmental contaminant exposure.

Abstract
BACKGROUND Traditional food (TF) consumption represents the main route of persistent organic pollutant (POP) exposure for indigenous Arctic Canadians. Ongoing dietary transitions away from TFs and toward imported foods (IFs) may contribute to decreasing POP exposures observed in these groups. METHODS To explore this issue, we combined the global fate and transport model GloboPOP and the human food chain bioaccumulation model ACC-Human Arctic to simulate polychlorinated biphenyl (PCB) exposure in two indigenous Arctic Canadian communities from the Inuvik region, Northwest Territories and Baffin region, Nunavut. Using dietary survey information from initial (1996-98) and follow-up (2005-07) biomonitoring campaigns in Inuvik and Baffin, we simulated PCB exposures (PCB-118, -138, -153, and -180) for each individual study participant and also whole study populations. RESULTS TF intake rates, particularly of marine mammals (MMs), were the most important predictors of modeled PCB exposure, while TF consumption did not associate consistently with measured PCB exposures. Further, reported mean TF intake increased from baseline to follow-up in both Inuvik (from 8 to 183gd(-1)) and Baffin (from 60 to 134gd(-1)), opposing both the expected dietary transition direction and the observed decrease in human PCB exposures in these communities (ΣPCB Inuvik: from 43 to 29ngglipid(-1), ΣPCB Baffin: from 213 to 82ngglipid(-1)). However dietary questionnaire data are frequently subject to numerous biases (e.g., recall, recency, confirmation), and thus casts doubt on the usefulness of these data. CONCLUSIONS Ultimately, our model's capability to reproduce historic PCB exposure data in these two groups was highly sensitive to TF intake, further underscoring the importance of accurate TF consumption reporting, and clarification of the role of dietary transitions in future POP biomonitoring of indigenous Arctic populations.
