RESUMEN
OBJECTIVE: To understand the perspectives of key informant experts regarding the relationship between food insecurity and gestational diabetes mellitus risk reduction behaviors among young American Indian and Alaska Native females. METHODS: Participants were adult key informants with expertise in food/nutrition and health within Tribal communities (N = 58) across the US. Data were collected through 1:1 interviews using a semistructured moderator guide and analyzed using thematic content analysis methods. RESULTS: Three themes included (1) diet and nutrition habits are formed through intergenerational food preferences and are driven by lasting implications of colonization; (2) young people are influenced by what their peers eat and the food environment, including outside of the home; and (3) the methods used to understand household food insecurity and nutrition habits in the parent study were likely limited. CONCLUSIONS AND IMPLICATIONS: Findings provide guidance as to where nutrition education and interventions may best support young Native females.

BACKGROUND: Mental health disorders still rank as leading causes of morbidity worldwide despite increasing awareness and improvements in treatment. Notably, low- and middle-income countries like Uganda, are disproportionately affected by such disorders. The burden of depressive symptoms in these countries is particularly high among students, aggravated by poverty, malnutrition, and inadequate public health governance, yet it is clearly under-researched, making it hard to achieve several of UN Sustainability Development Goals. Current treatment options are insufficient to tackle the increased burden of depressive disease. This is more challenging for low-resource regions especially in Sub-Saharan Africa, suggesting the need for alternative treatments that can swiftly be applied if proven effective. The main aim of this randomized controlled trial (RCT) is therefore to examine if a low-cost healthy diet (based on local Ugandan foods) combined with easy-to access mindfulness cognitive therapy can reduce depressive symptoms among university students in Uganda. METHODS: We will recruit female and male students at Makerere University, the largest public university in Uganda, to an open, intention-to-treat, two-armed RCT. Those who score above a predefined threshold on a self-reported assessment of depressive symptoms, measured by the Center for Epidemiological Studies - Depression score (CES-D), are eligible for study inclusion and will be randomized to either an intervention (n = 125) or a control (n = 125) group. The intervention group will receive educational group-based sessions on how to prepare a Mediterranean-type of healthy diet and how to adhere to the principles of mindfulness-based cognitive therapy. Outcome measures include self-reported depression symptoms, quality of life, and dietary intakes. In addition we will perform a cost-effectiveness analysis. The RCT intervention will last 9 months, followed by additional 15 months with regular data collections. DISCUSSION: We here describe a novel approach to treat depressive symptoms among university students living in resource constraint settings, by combining a healthy diet with low threshold psychotherapy. If this intervention succeeds, our project can be viewed as a step towards evidence-based behavior practices for young adults with a common mental disorder (depression) that are beneficial to public mental health initiatives and management. TRIAL REGISTRATION: The RCT is registered in ClinicalTrials.gov (ID: NCT05848973). The date of registration was August 14, 2023.

Despite beneficial cardiovascular effects, substantial long-term modulation of food pattern could only be achieved in a limited number of participants. The impact of attitude towards healthy nutrition (ATHN) on successful modulation of dietary behavior is unclear, especially in the elderly. We aimed to analyze whether the personal ATHN influences 12-month adherence to two different dietary intervention regimes within a 36-month randomized controlled trial. METHODS: 502 subjects were randomized to an intervention group (IG; dietary pattern focused on high intake of unsaturated fatty acids (UFA), plant protein and fiber) or control group (CG; dietary recommendation in accordance with the German Society of Nutrition) within a 36-month dietary intervention trial. Sum scores for effectiveness, appreciation and practice of healthy nutrition were assessed using ATHN questionnaire during the trial (n = 344). Linear regression models were used to investigate associations between ATHN and dietary patterns at baseline and at month 12. RESULTS: Retirement, higher education level, age and lower body mass index (BMI) were associated with higher ATHN sum scores. ATHN was similar in CG and IG. Higher baseline intake of polyunsaturated fatty acids (PUFA) and fiber as well as lower intake in saturated fatty acids (SFA) were associated with higher scores in practice in both groups. The intervention resulted in a stronger increase of UFA, protein and fiber in the IG after 12 months, while intake of SFA declined (p < 0.01). Higher scores in appreciation were significantly associated with higher intake of fiber and lower intake of SFA in the CG at month 12, whereas no associations between ATHN and macronutrient intake were observed in the IG after 12 months. CONCLUSIONS: While ATHN appeared to play a role in general dietary behavior, ATHN did not affect the success of the specific dietary intervention in the IG at month 12. Thus, the dietary intervention achieved a substantial modification of dietary pattern in the IG and was effective to override the impact of the individual ATHN on dietary behavior.

BACKGROUND: College students are vulnerable to high perceived stress (PS) and emotional eating (EE) levels, which are associated with their food consumption. In this study, we aimed to examine the links between perceived stress, emotional eating, and adherence to a healthy eating index. Furthermore, we aimed to test whether sociodemographic data and health measures, including body mass index and physical activity, are associated with perceived stress, emotional eating, or healthy eating index. METHODS: This study included students from King Abdulaziz University. The participants completed validated perceived stress, emotional eating, and short healthy eating index surveys via an online questionnaire from September to December 2022. Univariate linear regression analysis was performed to examine the association between perceived stress, emotional eating, and adherence to healthy eating index using the short healthy eating index. RESULTS: Of 434 students (49.8% male, mean age 21.7 ± 3.0 years), 11.3% had low, 72.0% moderate, and 16.7% high perceived stress. Students with moderate perceived stress had the highest short healthy eating index score (P = 0.001), outperforming those with low and high perceived stress for fruit juice (P = 0.002), fruits (P[Formula: see text]0.001), vegetables (P=0.03), greens and beans (P<0.001), whole grains (P=0.009), and seafood/plant proteins (P = 0.001) consumption. Also, emotional eating was significantly associated with short healthy eating index score (P = 0.04), fruit juice (P = 0.01) fruit consumption (P<0.001), added sugar (P=0.02) and saturated fatty acids (P = 0.03). Academic major was associated with perceived stress (P = 0.006) and emotional eating (p=0.04). Higher physical activity levels were associated with low perceived stress levels (P<0.001) and high short healthy eating index score (P=0.001), while high body mass index was associated with high emotional eating score (P<0.001). CONCLUSIONS: The findings confirmed that students are highly vulnerable to moderate and high perceived stress levels. Furthermore, high perceived stress is inversely associated with adherence to a healthy eating index, especially for fruits, vegetables, greens and beans, whole grains, and seafood and plant proteins consumption. Emotional eating, also, associated with students dietary pattern. Physical activity will be beneficial for reducing the level of perceived stress and improving overall dietary patterns.

Most participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) do not fully redeem their benefits due to barriers like transportation, confusing product eligibility, and unclear labeling. Online food shopping enables choice architecture to promote benefit redemption and maximize diet quality. We conducted a mixed-methods pilot randomized-controlled trial to assess the feasibility and acceptability of a pre-filled online grocery shopping cart to improve WIC benefit redemption and diet quality of grocery purchases. Rhode Island WIC participants (n = 24, mean age 29.4 ± 1.1 years, 75% Hispanic, 54% had never grocery shopped online) completed a baseline questionnaire and a simulated shopping episode (SSE), buying WIC and non-WIC items. After a week, we randomized participants into the intervention (personalized, modifiable carts pre-filled with 100% of the 2022 proposed WIC packages) or control (selected their items individually) groups before the second SSE. Both groups had WIC labels. We assessed feasibility using process data and percent agreement to feasibility questions, and acceptability via percent agreement to acceptability questions and post-intervention qualitative interviews. We conducted exploratory analyses to examine differences within and between groups at each timepoint for percent WIC benefit redemption and diet quality of grocery purchases, evaluated using the Grocery Purchase Quality Index-2016 (GPQI-2016) scores. Quantitative study measures suggest that the intervention was feasible and that the personalized, modifiable pre-filled cart was acceptable. These findings were supported during qualitative interviews, where participants highlighted time-savings, flexibility, and WIC labels as facilitators of WIC online shopping. Exploratory results showed significant increases in mean percent redemption of most WIC food categories and non-significant moderate increases in most GPQI-2016 scores. These measures are vital for the future adaptation of a full-scale efficacy trial in real-life settings.

The aim of this study was to use diverse perspectives of stakeholders to explore barriers to healthy eating, and attitudes, norms, and practices contributing to unhealthy food choices among school-aged children in Armenia. A qualitative study was carried out through focus group discussions and in-depth interviews, using the Theory of Planned Behavior. The study was conducted in 21 public schools located in three provinces (marzes) of Armenia: Shirak, Lori, and Tavush, and the capital city Yerevan. These study areas were chosen purposefully to target more vulnerable regions and have a geographically diverse sample. Purposive sampling techniques were used to choose the study participants. Five groups were targeted: high school students, school principals, teachers, school cafeteria staff members, and mothers of school children. Overall, 10 focus group discussions, and 51 in-depth interviews were conducted with a total of 94 participants. The study explored two main themes underlying unhealthy eating behaviors among school-aged children in Armenia - suboptimal preferences and restricted opportunities. Three subthemes were identified within the theme of suboptimal preferences: preferences/tastes, attitudes, and role models/normative referent, and another three subthemes within the theme of restricted opportunities: choice restrictions, time constraints, and financial barriers. The study found that most of the constructs of theory of planned behavior, such as general attitudes, preferences, perceived norms and perceived behavioral control, impacted unhealthy eating behaviors of school-aged children in Armenia. The recommendations for practice included enhancing the appeal of healthy foods, highlighting the significance of breakfast and healthy eating in educational activities utilizing role models, expanding and empowering school canteens, including higher grade students in school feeding programs, and extending school breaks to provide sufficient time for healthy eating.

Childhood eating behaviors are associated with weight status and laboratory assessments of dietary intake. However, little is known about how eating behaviors relate to the eating patterns and diet quality of children from marginalized populations when assessed in their natural environments. Therefore, we examined the association of food avoidant (e.g., food fussiness and satiety responsiveness) and food approach (e.g., food responsiveness and enjoyment of food) eating behaviors with children's meal size, eating frequency, and diet quality. We analyzed data from 61 predominately low-income Hispanic/Latinx preschool-aged children. Caregivers completed the Childhood Eating Behavior Questionnaire and two 24-h dietary recalls. From the recalls, we calculated meal size, eating frequency, and modified Diet Quality Index Scores (DQIS), and evaluated associations with eating behaviors using multivariable linear models. We also explored the relationship between eating behaviors and DQIS components. Food-avoidant subscales were associated with smaller meals and satiety responsiveness were associated with decreased snack frequency. Food approach subscales were not associated with meal size or eating frequency. Both food-avoidant and food-approach behaviors were associated with components of diet quality and caloric beverages outside of meal and snacks. These findings can inform future research on the relationship between child eating behaviors and dietary intake so that we can develop more tailored and effective interventions to promote healthy eating habits for low-income, Hispanic/Latinx preschool-aged children.

The main objective of this study was to examine the actor and partner effects between Perceived Workplace Support for Families (PWSFs) and family support (PFS), diet quality, and satisfaction with food-related life (SWFoL) in households with both parents working and adolescents, along with the role of the three family members' diet quality as a mediator. During the second year of the pandemic in Chile, 860 dual-earner parents of different sexes and their adolescent child (average age 13 years, with 50.7% being male) were recruited from two cities. Parents responded to a measure of PWSFs and the Perceived Family Support Scale. Mothers, fathers, and adolescents answered the Adapted Healthy Eating Index (AHEI) and the satisfaction with food-related life Scale. The examination employed the mediation Actor-Partner Interdependence Model and structural equation modeling for the analyses. Results showed that mothers' PWSFs improved their and their teenage children's SWFoL, while fathers' PWSFs only improved their SWFoL. The mothers' PFS improved their and the fathers' diet quality while enhancing their SWFoL and the adolescents' SWFoL. The fathers' PFS enhanced their and the adolescents' SWFoL. The mothers' PFS also indirectly enhanced their and the fathers' SWFoL via each parent's diet quality. Each family member's diet quality was positively related to their SWFoL, while mothers' diet quality was positively related to the fathers' SWFoL. These results imply that resources obtained by parents from PFS positively impact the SWFoL of the three family members through different mechanisms. They also highlight the importance of maternal family support for SWFoL during the pandemic.

(1) Background: Currently, numerous qualitative research studies on food and its influence on health are being conducted. In qualitative research, data are obtained by analyzing participants' responses. However, silence during conversation has been little studied. The aim of this study was to interpret the silences in the narratives of elderly people living alone about the potential risks of not keeping a healthy diet. (2) Methods: This is a descriptive and interpretative observational study under the qualitative research paradigm following a phenomenological and ethnographic perspective. The study was developed in two phases with people over 65 years old. In the first phase, from June 2021 to January 2022, 90 interviews, 12 life history analyses, 58 food diaries and 51 free listings (cultural domain technique) were conducted. In the second phase, from March to June 2022, 3 participatory workshops and 24 pile sorts (cultural domain technique) were conducted, as well as 3 focus groups. Only data from participants over 65 years old living alone are analyzed in this paper. The ATLAS-ti (Version 22) qualitative analysis software was used for coding and data analysis. (3) Results: The results show that elderly people living alone would sometimes remain silent during the various conversations conducted within the research. This silence reflects their desire to downplay the risks to their health from not eating well due to their unwanted loneliness. The people participating in our research had chronic health problems, financial insecurity and emotional problems. (4) Conclusions: We concluded that elderly people living alone are unable to maintain a healthy diet because they downplay their risk of malnutrition. This mindset is caused by their loneliness and bolstered by a situation of learned helplessness and social injustice.

We examined whether people with high BMI sampled from two different countries were more susceptible to behavioural change via an implicit, rather than explicit, intervention. We measured BMI and used three types of cue interventions (implicit vs explicit healthy lifestyle cue vs neutral cue) to examine their impact on our participants' food choice using the Fake Food Buffet. Healthiness of the meal chosen was measured by the percentage of healthy food items in the meal. Portion size of their chosen meal was operationalised by the total number of food items chosen and its total calorie content was also estimated. Participants were recruited from the United Kingdom (N = 264) and Indonesia (N = 264). Our results indicated that while explicit food cues were overall more effective, implicit cues were a more effective strategy to change food choice behaviours among individuals with high BMI. Participants with high BMI were more likely to regulate the healthiness of their meal and less likely to regulate its portion size or calorie content. The efficacy of our healthy eating interventions was cross-culturally generalizable. Our study supports previous research that implicit cues of a healthy lifestyle might be a more effective behavioural change strategy for individuals with high BMI.

In food choices, conflict arises when choosing between a healthy, but less tasty food item and a tasty, but less healthy food item. The underlying assumption is that people trade-off the health and taste properties of food items to reach a decision. To probe this assumption, we presented food items either as colored images (image condition, e.g. photograph of a granola bar) or as pre-matched percentages of taste and health values (text condition, e.g., 20% healthy and 80% tasty). We recorded choices, response times and electroencephalography activity to calculate mid-frontal theta power as a marker of conflict. At the behavioral level, we found higher response times for healthy compared to unhealthy choices, and for difficult compared to easy decisions in both conditions, indicating the experience of a decision conflict. At the neural level, mid-frontal theta power was higher for healthy choices than unhealthy choices and difficult choices compared to easy choices, but only in the image condition. Those results suggest that either conflict type and/or decision strategies differ between the image and text conditions. The present results can be helpful in understanding how dietary decisions can be influenced towards healthier food choices.

Parents play a crucial role in deciding what foods to introduce to their infants during the transition from milk to solids. This study examined the challenges they face, including adherence to official complementary feeding recommendations and the struggles and concerns across different stages of feeding. Specifically, this study focused on the initial stage (transition from breastmilk/formula to mashed foods), middle stage (consumption of mashed foods and some fingerfoods, transitioning towards family foods) and late stage (complete transition to family diet). Findings from 22 semi-structured interviews with Swiss parents reveal that, despite being well-informed, practical obstacles such as returning to work, limited time for preparing homemade foods, managing multiple children, and food preferences often hinder adherence. Safety concerns like allergies and choking were prominent early on but decreased as infants grew older and parents gained confidence. In the middle phase, concerns shifted towards pesticides, indicating a growing awareness of food quality. Maintaining a healthy diet was a constant concern, with early reassurance from breastfeeding or formula feeding giving way to worries about balanced nutrition as solids became more prominent. Time constraints were particularly significant in the first two stages, due to the effort of preparing small amounts of mash and later cooking separate meals. Tailored support and clear communication can help parents navigate these challenges and promote healthier feeding practices.

This study aimed to explore the longitudinal associations between healthy eating habits, resilience, insomnia, and Internet addiction by using a cross-lagged panel analysis of Chinese college students. Overall, 807 Chinese college students completed questionnaires on healthy eating habits, resilience, insomnia, and Internet addiction from August 2020 (time 1, T1) to November 2020 (time 2, T2), and were selected for the data analyses. Healthy eating habits (T1) had significant effects on resilience (T2; ß = 0.064, p < 0.05) and insomnia (T2; ß = -0.064, p < 0.05), but not Internet addiction (T2; ß = -0.028, p > 0.05). Insomnia (T1) negatively predicted resilience (T2; ß = -0.098, p < 0.01). Insomnia was bidirectionally associated with Internet addiction (Internet addiction at T1 to insomnia at T2: ß = 0.085, p < 0.01; insomnia at T1 to Internet addiction at T2: ß = 0.070, p < 0.05). Additionally, Internet addiction (T1) significantly predicted resilience (T2; ß = -0.075, p < 0.05). This study further expanded the understanding of the longitudinal associations between healthy eating habits, resilience, insomnia, and Internet addiction, which provided higher-level evidence and important implications for the interventions for reducing college students' Internet addiction, developing healthy eating habits, and improving resilience and sleep health.

We Investigated how promoting diverse, healthy food options affects long-term dietary choices. We hypothesized that encouraging exploration of nutritious plant-based foods would lead to lasting improvements in diet. Participants (N = 211) were randomly assigned into two groups for a 6-week intervention: The fixed menu group was given the same large menu every week, while the changing menu group received a new small menu each week. At the end of the intervention both groups were exposed to the same menu suggestions. Food diversity evaluation was based on weekly reports collected during the intervention. Self-reported adherence to Mediterranean diet components was assessed using the I-MEDAS screener. The proportion of plant-based foods in participants' diets was estimated using a 0-100% scale based on self-report. Both items were evaluated using online questionnaires given to participants at baseline, at the end of the intervention, as well as three and six months after the intervention concluded. Results mean(SD) demonstrated that participants in fixed menu group explored a significantly wider array of items 26.33(11.64) than those in the changing menus group [19.79(10.29), t(202) = 4.25, p < 0.001, Cohen's d = 0.60]. A repeated measures analysis of covariance rmANCOVA revealed that short-term increase in I-MEDAS and PBD score were noted in both groups; however, only participants with the fixed menu sustained this increase at months follow-up [diff = 1.50, t(132) = 4.50, p < 0.001 Our findings suggest that manipulating the rate of exposure to food suggestions may affect overall dietary variety. It seems that early presentation with options may increase overall dietary variety and may even support longer-term habits. This study contributes to developing effective interventions and highlights the challenge of promoting exploratory behavior in nutrition.

Personalised dietary advice has become increasingly popular, currently however most approaches are based on an individual's genetic and phenotypic profile whilst largely ignoring other determinants such as socio economic and cognitive variables. This paper provides novel insights by testing the effectiveness of personalised healthy eating advice concurrently tailored to an individual's socio-demographic group, cognitive characteristics, and sensory preferences. We first used existing data to build a synthetic dataset based on information from 3654 households (Study 1a), and then developed a cluster model to identify individuals characterised by similar socio-demographic, cognitive, and sensory aspects (Study 1b). Finally, in Study 2 we used the characteristics of 8 clusters to build 8 separate personalised food choice advice and assess their ability to motivate the increased consumption of fruit and vegetables and decreased intakes of saturated fat and sugar. We presented 218 participants with either generic UK Government "EatWell" advice, advice that was tailored to their allocated cluster (matched personalised), or advice tailored to a different cluster (unmatched personalised). Results showed that, when compared to generic advice, participants that received matched personalised advice were significantly more likely to indicate they would change their diet. Participants were similarly motivated to increase vegetable consumption and decrease saturated fat intake when they received unmatched personalised advice, potentially highlighting the power of providing alternative food choices. Overall, this study demonstrated that the power of personalizing food choice advice, based on a combination of individual characteristics, can be more effective than current approaches in motivating dietary change. Our study also emphasizes the viability of addressing population health through automatically delivered web-based personalised advice.

Food choices are closely linked to culture, social relationships, and health. Because many adults spend up to half their time at work, the workplace provides a venue for changing population health-related behaviors and norms. It is unknown whether the effects of a workplace intervention to improve health behaviors might spread beyond participating employees due to social influence. ChooseWell 365 was a randomized controlled trial testing a 12-month healthy eating intervention grounded in principles of behavioral economics. This intervention leveraged an existing cafeteria traffic-light labeling system (green = healthy; red = unhealthy) in a large hospital workplace and demonstrated significant improvements in healthy food choices by employees in the intervention vs. control group. The current study used data from over 29 million dyadic purchasing events during the trial to test whether social ties to a trial participant co-worker (n = 299 intervention, n = 302 control) influenced the workplace food choices of non-participants (n = 7900). There was robust evidence that non-participants who were socially tied to more intervention group participants made healthier workplace food purchases overall, and purchased a greater proportion of healthy (i.e., green) food and beverages, and fewer unhealthy (i.e., red) beverages and modest evidence that the benefit of being tied to intervention participants was greater than being tied to control participants. Although individual-level effect sizes were small, a range of consistent findings indicated that this light-touch intervention yielded spillover effects of healthy eating behaviors on non-participants. Results suggest that workplace healthy eating interventions could have population benefits extending beyond participants.

OBJECTIVES: Mexico exhibits one of the highest prevalence rates of overweight and obesity globally, accompanied by a surge in non-communicable diseases, which in turn leads to elevated mortality rates. Existing efforts to address rising obesity rates have shown limited effectiveness. Maternal weight, diet, and physical activity (PA) during pregnancy affect the mother's and offspring's health. Despite the importance of establishing and engaging in healthy behaviors during pregnancy, little is known about which factors impact these behaviors among pregnant women in Mexico. This study explored perspectives on factors impacting healthy dietary behaviors and PA in pregnancy from pregnant women and health care professionals in Mexico. METHODS: We conducted semistructured interviews with 11 pregnant women and 12 health care professionals working in prenatal care. Data were analyzed using qualitative content analysis in a stepwise inductive approach. RESULTS: Classifying factors at the 1) individual level, 2) relational level, and 3) health care system level, three overall themes emerged. At the individual level, challenges with lack of time and competing priorities as well as knowledge of healthy dietary behaviors and PA were identified. At the relational level, influencing factors encompassed financial, social, and emotional support along with descriptive norms. At the health care system level, guidelines for PA during pregnancy and the quality of care were noted. CONCLUSIONS: This study identified factors impacting healthy dietary behaviors and PA in pregnancy in Mexico. Important considerations for future interventions include addressing sociocultural norms around healthy dietary behaviors and PA in pregnancy and involving pregnant women's families, closest social networks, and health care professionals working at the prenatal care unit.

In the UK people living in disadvantaged communities are less likely than those with higher socio-economic status to have a healthy diet. To address this inequality, it is crucial scientists, practitioners and policy makers understand the factors that hinder and assist healthy food choice in these individuals. In this scoping review, we aimed to identify barriers and facilitators to healthy eating among disadvantaged individuals living in the UK. Additionally, we used the Theoretical Domains Framework (TDF) to synthesise results and provide a guide for the development of theory-informed behaviour change interventions. Five databases were searched, (CINAHL, Embase, MEDLINE, PsycINFO, and Web of Science) for articles assessing healthy dietary intake of disadvantaged adults living in the UK. A total of 50 papers (34 quantitative; 16 qualitative) were included in this review. Across all studies we identified 78 barriers and 49 facilitators found to either impede and/or encourage healthy eating. Both barriers and facilitators were more commonly classified under the Environmental, Context and Resources TDF domain, with 74% of studies assessing at least one factor pertaining to this domain. Results thus indicate that context related factors such as high cost and accessibility of healthy food, rather than personal factors, such as lack of efficiency in healthy lifestyle drive unhealthy eating in disadvantaged individuals in the UK. We discuss how such factors are largely overlooked in current interventions and propose that more effort should be directed towards implementing interventions that specifically target infrastructures rather than individuals.

Eating low amounts of healthy foods leads to high rates of diet-related diseases. How can we control and reduce the increase in these diseases? One of the recommendations is to improve nutritional competence, which means greater health consciousness. The objective of the present study is to determine the influence of health consciousness on the dimensions of perceived value and their impact on the willingness to consume foods from a healthy brand. Through a non-experimental, cross-sectional, and explanatory study, the responses of 518 participants (men and women) who confirmed being consumers of the healthy brands of food were analyzed. The study included adults aged from 18 to 58 years recruited using non-probability sampling. Data was collected using a self-report form and statistically analyzed using Smart PLS. The findings support that health awareness positively and significantly influences perceived quality value, perceived financial value, perceived social value, and perceived emotional value; contrary to this, it was detected that the perceived financial value does not influence the willingness to consume foods from healthy brands. This study contributes significantly to health science by showing how the theory of perceived value predicts the intention to consume healthy brands, with health consciousness intervening in this prediction. Therefore, it is concluded that the study population that consumes healthy foods has experienced the positive impact of perceived value and reports that the factors that comprise it influence their intention to consume healthy foods.

Urban Indigenous populations encounter distinctive challenges in maintaining traditional dietary practices, compounded by the complexities of socio-economic and environmental factors and the modern urban lifestyle. This qualitative study explores the perceptions of healthy eating, along with the facilitators and barriers to such practices, among urban Indigenous peoples in Saskatoon, Regina, and Prince Albert. Through virtual interviews, we engage 14 participants from these cities. Utilizing NVivo for thematic coding, we apply inductive thematic analysis to reveal relevant themes. The study highlights a preference for nutrient-rich, natural, and minimally processed foods, with a significant emphasis on incorporating traditional Indigenous foods into diets. These preferences are deeply entwined with cultural identity and underscore the importance of traditional foods in maintaining cultural heritage and promoting well-being. Despite the intrinsic value of these traditional foods, participants face several barriers to healthy eating, including economic constraints, limited access to traditional foods, and the psychological impacts of historical trauma. Nevertheless, facilitators such as community and family support, engagement in traditional food practices, and a growing awareness of nutritional knowledge are identified as being crucial in supporting healthy dietary choices. This research underscores the complex interplay of cultural, economic, and environmental factors in shaping the dietary practices of urban Indigenous peoples.
