Manna A, Vidgen H, Gallegos D. Examining the effectiveness of food literacy interventions in improving food literacy behavior and healthy eating among adults belonging to different socioeconomic groups- a systematic scoping review. Syst Rev 2024; 13:221. [PMID: 39198926 PMCID: PMC11350956 DOI: 10.1186/s13643-024-02632-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Accepted: 07/30/2024] [Indexed: 09/01/2024] Open
Abstract
BACKGROUND In high-income countries, significant diet-related health inequalities exist between people of different socioeconomic backgrounds. Individuals who face socioeconomic challenges are less likely to meet dietary guidelines, leading to increased incidence and prevalence of morbidity and mortality associated with dietary risk factors. To promote healthy eating, strategies may focus on individual-level factors (e.g., knowledge, skills, and behavior) along with broader societal factors (e.g., social determinants of health). The concept of food literacy is considered an individual-level factor and has been framed as a skill set that individuals must possess to effectively navigate the complexities of the modern food system. Food literacy interventions can be a complementary but effective tool for encouraging healthy eating behavior among diverse populations, including those facing socioeconomic disadvantage. However, there is limited evidence to guide the design of food literacy intervention for vulnerable population groups. In the process of developing an ideal portfolio of solutions and strategies to promote food literacy and healthy eating for people experiencing socioeconomic disadvantage, this systematic scoping review aims to comprehensively examine the effects of food literacy interventions on promoting food literacy behavior and healthy eating in adults (18 years and above) from various socioeconomic groups (SEGs) in high-income countries. METHODS The review includes both qualitative and quantitative papers obtained from academic databases, including MEDLINE (via EBSCOhost), Embase, Web of Science, and Google Scholar. In addition to the electronic search, manual forward and backward citation searching will be conducted to identify additional relevant papers. Food literacy interventions will be evaluated across four domains: planning and management, selection, preparation, and consumption. Papers included in the review will be analyzed for process, impact, and outcome evaluation. The main outcome of a food literacy intervention is the modification in eating behavior, while the mechanism for this action will be through impact measure of food literacy behaviors. Implementation factors will be extracted for process evaluation. This review will also include a range of dietary behavior measures, such as diet quality index and dietary intake indicator. The screening process for all citations, full-text articles, and abstract data will be carried out by two reviewers independently. In case of any potential conflicts, they will be resolved through discussion. The quality of quantitative studies will be reviewed using the JBI critical appraisal checklist for analytical cross-sectional studies. The "Consolidated Criteria for Reporting Qualitative Studies (COREQ)" will be used to report on the quality of qualitative papers.

Abstract
Adolescent obesity continues to be a public health challenge with poor quality diets contributing to its etiology. As part of the process to plan health promotion and policy interventions, understanding adolescents perceived facilitators and barriers to healthful eating is important. An integrative convergent mixed-methods systematic review was used to synthesize qualitative and quantitative evidence from studies among adolescents aged 10-19 years in high-income countries. Medline, Embase, PsycInfo, and Scopus were searched for peer-reviewed articles published between 2010 and 2023 and exploring adolescents' perspectives on healthful eating and contemporary contextual factors. Transformed quantitative data were integrated with qualitative data. Text was coded into subthemes and themes using an inductive approach. Key facilitators included health and physical appearance; motivation; taste; nutrition knowledge, awareness, and skills; nutrition education access; availability and accessibility of healthful foods; family; and social influences and digital media. Key barriers included taste and cravings for unhealthful foods; mood; lack of motivation, awareness, knowledge, and skills; high availability and low cost of unhealthful foods; peers and social influences; ineffective school policies; high density of fast-food outlets; unhealthful food advertising; digital influences; and time constraints. Social, behavioral, digital, and food environmental factors should be considered from an adolescent perspective in the design of education, health promotion, and policy interventions.

Abstract
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.

The potential influence of the digital food retail environment on health: A systematic scoping review of the literature. Obes Rev 2024; 25:e13671. [PMID: 38104965 DOI: 10.1111/obr.13671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 10/01/2023] [Accepted: 11/03/2023] [Indexed: 12/19/2023]
Abstract
INTRODUCTION The digital food retail environment (defined in this study as a digital platform, app or website where food can be purchased by individuals for personal consumption) is an emerging component of the wider food system. We aimed to systematically search and review the literature to understand the potential influence of the digital food retail environment on population diets and health. METHODS Four databases (across health, business, and marketing) and grey literature were searched using terms relating to "food and beverages," "digital," and "purchasing." Identified studies were included if they examined any aspect of the digital food retail environment where outcomes were examined with a health-related focus and were published before September 2023. All study designs were included (quantitative, qualitative, observational, and experimental). Reviews and conference abstracts were excluded. RESULTS We identified 21,382 studies, of which 57 articles were eligible for inclusion. Of the 57 included studies, 30 studies examined online grocery retail, 22 examined online food delivery platforms, and five examined meal kit subscription services. Of the 30 studies examining online grocery retail, six studies reported that customers believed they purchased fewer unhealthy food and beverages when shopping online, compared with shopping in-store. Nevertheless, customers also reported that their ability to choose healthy foods and beverages was reduced when shopping online due to difficulty in product comparison. Studies that examined online food delivery platforms primarily found that they promoted unhealthy foods and beverages more often than healthy options, through extensive use of marketing practices such as price discounts and images, and that unhealthy food offerings on these platforms dominate. Meal kit subscription services offered mostly healthy meals, with studies suggesting that these types of services may help individuals alleviate some of their "mental load" and stress related to cooking meals for their families. CONCLUSIONS The literature describing the digital food retail environment was found to be diverse, with different aspects having potential to impact health in different ways. Some evidence suggests that online grocery retail and meal kit subscription services may have positive population dietary impacts, whereas online food delivery platforms appear likely to promote unhealthy food purchasing. However, the current evidence base is fragmented, with many knowledge gaps. Further research is required to understand the influence of the digital food retail environment on population diets and how these environments can be designed to support healthy food choices.

Abstract
PURPOSE To examine differences in dietary, physical activity, and food selection behaviors of Utah SNAP-Ed participants who had varied breadth of engagement with various components of multilevel programming. METHOD SNAP-Ed participants received a survey approximately 1 year after participating in nutrition classes. The survey measured diet, physical activity, and food selection behaviors and breadth of engagement with components of SNAP-Ed programming. Components of programming included nutrition education for adults and youth, nudge programs in food pantries and corner stores, farmers' market booths, social marketing campaign materials, and social media platforms. Kruskal-Wallis tests assessed differences in behaviors between varying breadths of program engagement. RESULTS Among the 124 respondents, certain dietary behaviors improved with increased breadth of program engagement including intake of vegetables, low-fat dairy, and lean protein. Food selection behaviors including using MyPlate and preparing healthy foods on a budget, also improved with increased engagement. Physical activity was not impacted by additional breadth of exposure. CONCLUSIONS AND IMPLICATIONS Findings suggest that multilevel comprehensive programming may enhance the impact of SNAP-Ed education for certain behaviors. Additional research is warranted on the impact of SNAP-Ed multilevel programming on targeted behaviors and health outcomes.

Abstract
PURPOSE OF REVIEW To review the upstream determinants of overweight and obesity in Europe, including food and built environments, and political, commercial, and socioeconomic determinants. RECENT FINDINGS Overweight and obesity affect 60% of European adults, and one in three children, and are more common in individuals with low compared to high socioeconomic position (SEP). Individuals in low SEP groups are more exposed to unhealthy built and food environments, including higher exposure to unhealthy food marketing. Industries influencing the food system have much economic power, resulting in ignoring or silencing the role of ultra-processed foods and commercial practices in weight gain. Overall, effective policies to address overweight and obesity have been insufficiently implemented by governments. To accelerate implementation, strengthened political commitment is essential. Policies must also focus on the upstream, structural, and systemic drivers of overweight and obesity; be comprehensive; and target socioeconomic inequalities in diets and physical activity.

Abstract
Introduction Maintaining an affordable and nutritious diet can be challenging, especially for those living under the conditions of poverty. To fulfill a healthy diet, consumers must make difficult decisions within a complicated food landscape. Decisions must factor information on health and budget constraints, the food supply and pricing options at local grocery stores, and nutrition and portion guidelines provided by government services. Information to support food choice decisions is often inconsistent and challenging to find, making it difficult for consumers to make informed, optimal decisions. This is especially true for low-income and Supplemental Nutrition Assistance Program (SNAP) households which have additional time and cost constraints that impact their food purchases and ultimately leave them more susceptible to malnutrition and obesity. The goal of this paper is to demonstrate how the integration of data from local grocery stores and federal government databases can be used to assist specific communities in meeting their unique health and budget challenges. Methods We discuss many of the challenges of integrating multiple data sources, such as inconsistent data availability and misleading nutrition labels. We conduct a case study using linear programming to identify a healthy meal plan that stays within a limited SNAP budget and also adheres to the Dietary Guidelines for Americans. Finally, we explore the main drivers of cost of local food products with emphasis on the nutrients determined by the USDA as areas of focus: added sugars, saturated fat, and sodium. Results and discussion Our case study results suggest that such an optimization model can be used to facilitate food purchasing decisions within a given community. By focusing on the community level, our results will inform future work navigating the complex networks of food information to build global recommendation systems.

Abstract
Globally, the adoption and implementation of policies to improve the healthiness of food environments and prevent population weight gain have been inadequate. This is partly because of the complexity associated with monitoring dynamic food environments. Crowdsourcing is a citizen science approach that can increase the extent and nature of food environment data collection by engaging citizens as sensors or volunteered computing experts. There has been no literature synthesis to guide the application of crowdsourcing to food environment monitoring. We systematically conducted a scoping review to address this gap. Forty-two articles met our eligibility criteria. Photovoice techniques were the most employed methodological approaches (n = 25 studies), commonly used to understand overall access to healthy food. A small number of studies made purpose-built apps to collect price or nutritional composition data and were scaled to receive large amounts of data points. Twenty-nine studies crowdsourced food environment data by engaging priority populations (e.g., households receiving low incomes). There is growing potential to develop scalable crowdsourcing platforms to understand food environments through the eyes of everyday people. Such crowdsourced data may improve public and policy engagement with equitable food policy actions.

Perceptions of dietary intake amongst Black, Asian and other minority ethnic groups in high-income countries: a systematic review of qualitative literature. BMC Nutr 2023; 9:85. [PMID: 37443077 DOI: 10.1186/s40795-023-00743-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 07/04/2023] [Indexed: 07/15/2023] Open
Abstract
BACKGROUND Minority ethnic groups are a fast-growing population in many high-income countries, partly due to the increasing population of immigrants and second-generation migrants. The dietary practices of some of these minority ethnic groups might make them to be disproportionately affected by obesity and increase their risks of developing non-communicable diseases. Population-specific interventions and strategies are vital to addressing poor nutritional practices among this population. Thus, this study systematically reviewed the perceptions of dietary intake amongst Black, Asian and other minority ethnic groups in high-income countries. METHODS This systematic review was conducted in line with the guidelines of the Joanna Briggs Institute (JBI) methodology for systematic reviews, using a meta-aggregative design. This systematic review identified and synthesised qualitative literature on the perceptions of dietary intake amongst BlackAsian and other minority ethnic groups in high-income countries. An extensive and comprehensive database search was conducted between January 2000 - May 2022 and included twenty (20) studies that met the eligibility criteria from six countries. The included studies were assessed for quality using the JBI qualitative assessment and review instrument. The JBI data extraction tools were used to retrieve relevant data from included articles, and the data were thematically analysed. RESULTS We identified eight major themes across this database: (1) "Social and Cultural Factors," (2) "Availability and Accessibility," (3) "Family and Community Influences," (4) "Food Preferences", (5) "Home Country Food Versus Host Country Food" (6) "Dietary Acculturation" (7) "Health and Healthy Eating" (8) "Perception of Nutritional Information." CONCLUSION Overall, Black, Asian, and other minority ethnic groups individuals were found to be aware of the effects of unhealthy eating on their health, and some of them have nutritional knowledge, but social and cultural factors, including structural factors, were deterrents to their healthy eating behaviours. An important finding from this review is that some participants believed that nutritional information, based on bio-medical science, was intended for only White population groups and that it was antagonistic to their cultural and community well-being.

Healthy Food Prices Increased More Than the Prices of Unhealthy Options during the COVID-19 Pandemic and Concurrent Challenges to the Food System. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:3146. [PMID: 36833837 PMCID: PMC9967271 DOI: 10.3390/ijerph20043146] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 02/07/2023] [Accepted: 02/08/2023] [Indexed: 06/09/2023]
Abstract
Food prices have escalated due to impacts of the COVID-19 pandemic on global food systems, and other regional shocks and stressors including climate change and war. Few studies have applied a health lens to identify the most affected foods. This study aimed to assess costs and affordability of habitual (unhealthy) diets and recommended (healthy, equitable and more sustainable) diets and their components in Greater Brisbane, Queensland, Australia from 2019 to 2022 using the Healthy Diets Australian Standardised Affordability and Pricing protocol. Affordability was determined for reference households at three levels of income: median, minimum wage, and welfare-dependent. The recommended diet cost increased 17.9%; mostly in the last year when the prices of healthy foods, such as fruit, vegetables and legumes, healthy fats/oils, grains, and meats/alternatives, increased by 12.8%. In contrast, the cost of the unhealthy foods and drinks in the habitual diet 'only' increased 9.0% from 2019 to 2022, and 7.0% from 2021 to 2022. An exception was the cost of unhealthy take-away foods which increased by 14.7% over 2019-2022. With government COVID-19-related payments, for the first time recommended diets were affordable for all and food security and diets improved in 2020. However, the special payments were withdrawn in 2021, and recommended diets became 11.5% less affordable. Permanently increasing welfare support and providing an adequate minimum wage, while keeping basic, healthy foods GST-free and increasing GST to 20% on unhealthy foods, would improve food security and diet-related health inequities. Development of a Consumer Price Index specifically for healthy food would help highlight health risks during economic downturns.

Abstract
The present study aims to examine whether multiple dietary factors affect the mental health of older adults amid the COVID-19 pandemic. It proposes an integrative dietary framework that highlights environmental, nutritional, and social aspects of diet for healthy aging. Based on a sample of 7858 Chinese older adults, the associations between diet and depressive symptoms, along with the rural-urban divide, were examined using zero-inflated negative binomial regression. Overall, protein intake (incidence-rate ratio [IRR] = 0.89, p < 0.001), frequency of family dining together (IRR = 0.98, p < 0.001), and using tap water for cooking (IRR = 0.92, p < 0.01) were associated with lower incidence rates of depressive symptoms among older adults. Among rural older adults, frequency of family dining together (IRR = 0.97, p < 0.001) and tap water use (IRR = 0.89, p < 0.001) were associated with fewer depressive symptoms. However, urban residents who had a higher frequency of family dining together (IRR = 0.98, p < 0.05) and protein intake (IRR = 0.81, p < 0.001) exhibited fewer depressive symptoms. The findings revealed multifaceted dietary pathways towards healthy aging, which call for policies and interventions that improve diet quality for community-dwelling older adults.

Shifting the social determinants of food insecurity during the COVID-19 pandemic: the Australian experience. Food Secur 2023; 15:151-170. [PMID: 36160693 PMCID: PMC9483265 DOI: 10.1007/s12571-022-01318-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Accepted: 08/31/2022] [Indexed: 01/21/2023]
Abstract
We aimed to explore experiences of government-led actions on the social determinants of food insecurity during Australia's COVID-19 pandemic response (which included novel, yet temporary, social protection measures to support Australians facing hardship during state-wide lockdowns). During November-December 2020, we conducted in-depth interviews with 24 Victorians who received government income support (prior to COVID-19) and the temporary COVID-19 specific payments. Interviews were guided by a theoretical understanding of the social determinants of health and health inequities, which we aligned to the social policy context. Data were audio-recorded, transcribed, inductively coded, categorised and thematically analysed. Our sample included mostly women (n = 19) and single parents (n = 13). Interviews reflected four key themes. Firstly, participants described 'battles all around them' (i.e., competing financial, health and social stressors) that were not alleviated by temporary social policy changes and made healthy eating difficult to prioritise during the pandemic. Secondly, housing, income, job, and education priorities rendered food a lower and more flexible financial priority - even with 18 participants receiving temporary income increases from COVID-19 Supplements. Thirdly, given that food remained a lower and more flexible financial priority, families continued to purchase the cheapest and most affordable options (typically less healthful, more markedly price discounted). Finally, participants perceived the dominant public and policy rhetoric around income support policies and healthy eating to be inaccurate and shaming - often misrepresenting their lived experiences, both prior to and during COVID-19. Participants reported entrenched struggles with being able to afford basic living costs in a dignified manner during COVID-19, despite temporary social protection policy changes. To reduce inequities in population diets, a pre-requisite to health, all stakeholders must recognise an ongoing responsibility for adopting long-term food and social policies that genuinely improve lived experiences of food insecurity and poverty.

The Effect of Food Vouchers and an Educational Intervention on Promoting Healthy Eating in Vulnerable Families: A Pilot Study. Nutrients 2022; 14:nu14234980. [PMID: 36501009 PMCID: PMC9739317 DOI: 10.3390/nu14234980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/18/2022] [Accepted: 11/21/2022] [Indexed: 11/25/2022] Open
Abstract
Cost has been reported as the main barrier to healthy eating in vulnerable groups. We aimed to evaluate the effect of a nutrition education intervention on adherence to Mediterranean Diet and health when providing food vouchers. This pilot study has a randomized control trial design. We included 66 vulnerable users from the Red Cross of Zaragoza (Spain). Intervention and control group individuals received 120 euros/month of food vouchers over 3 months to be spent in supermarkets (60 euros/month if under 12 y) plus a 10-week nutrition education program for the intervention group. Family food purchases were assessed using electronically recorded supermarket-obtained transactions. During and at the end of the intervention the percentage of healthy food was higher in the intervention than in the control group. Once the nutrition education was over, differences between groups dissipated. In the intervention group, health parameters improved, particularly weight-status, lipids, and liver enzymes. Control participants gained weight, although lipid and liver enzymes improved. Blood pressure and HbA1c did not improve in either the intervention or the control group. In conclusion, providing unrestricted food vouchers to vulnerable groups to increase healthy food consumption appears to be insufficient and should be accompanied by medium-long term nutrition education.

Abstract
Background/aims Evidence points toward more sustainable and health-conscious dietary behaviors among individuals with higher socioeconomic status. However, these differences vary considerably depending on which indicator of socioeconomic status is examined. Here, we present a systematic parallel investigation of multiple indicators of socioeconomic status as predictors of animal food consumption frequency and selected food-related behaviors in Germany. Methods Data from the German subsample of two large representative European consumer studies (Study 1 n = 1,954; Study 2 n = 2,045) was used. We assessed the associations between the socioeconomic indicators income, current occupation as well as education and consumption frequency of animal foods and selected food-related behaviors in separate ordinal logistic regressions. Results Individuals with higher educational attainment engaged in more sustainable and health-conscious dietary behaviors, indicated by significant associations between educational attainment and the consumption frequency of animal foods. Low- and middle-income participants consumed processed meat more frequently (Study 1 only; medium income: OR 1.5, CI 1.09-2.05, p = 0.012; low income: OR 1.43, CI 1.01-2.05, p = 0.047) and fish less frequently (Study 2 only; medium income: OR 0.76, CI 0.59-0.97, p = 0.026; low income: OR 0.061, CI 0.46-0.82, p < 0.001) than participants with high income. Current occupation did not predict the consumption of animal foods or food-related behaviors. Intake frequency of animal-based foods indicates that most participants exceeded national dietary recommendations for meat and processed meat and remained below recommendations for fish and dairy/eggs intake. Conclusion Educational attainment appears to be the strongest and most consistent socioeconomic indicator of sustainable dietary choices in Germany based on current large, representative studies. Future efforts should be directed toward education interventions about nutrition and interpretation of food labels to compensate for differences in dietary behavior among groups with different levels of education.

Abstract
Cooking is crucial to the achievement of healthy eating habits, and the internet, as host of culinary recipes websites, is a medium for the dissemination of cooking-related content. Research has revealed that most recipes available on internet sites do not have healthy characteristics when compared to recommendations for healthy eating, even the ones promoted as 'healthy'. This study investigated culinary recipes available on the 'healthy eating' section of a popular Brazilian recipe-sharing website. Recipes (n = 814) were analyzed with a validated framework based on national dietary guidelines. Ingredients (n = 5887) were classified according to the extension and purpose of their industrial processing. The recipes' titles were content analyzed to identify the health-related words and phrases used. Recipes contained ultra-processed foods and not enough unprocessed or minimally processed foods, such as legumes (4.7%, n = 380), nuts and seeds (18.4%, n = 150), and fruits (n = 32.7%, n = 263). The recipes' titles mentioned 564 health-related terms, appealing to physical characteristics, including weight loss, and fads, such as gluten-free, dukan, low-carb, detox, fitness, ripped body, and belly burner. Therefore, the 'healthy' recipes available on the Brazilian recipe-sharing website presented many aspects not in accordance with national dietary guidelines.

Less meat in the shopping basket. The effect on meat purchases of higher prices, an information nudge and the combination: a randomised controlled trial. BMC Public Health 2022; 22:1137.

Abstract
Background Reduced meat consumption benefits human and planetary health. Modelling studies have demonstrated the significant health and environmental gains that could be achieved through fiscal measures targeting meat. Adding other interventions may enhance the effect of a fiscal measure. The current study aimed to examine the effect of higher meat prices, an information nudge and a combination of both measures on meat purchases in a three-dimensional virtual supermarket. Methods A parallel designed randomised controlled trial with four conditions was performed. Participants (≥ 18 years) were randomly assigned to the control condition or one of the experimental conditions: a 30% price increase for meat (‘Price condition’), an information nudge about the environmental impact of meat production and consumers’ role in that regard (‘Information nudge condition’) or a combination of both (‘Combination condition’). Participants were asked to shop for their household for one week. The primary outcome was the difference in the total amount of meat purchased in grams per household per week. Results Between 22 June 2020 and 28 August 2020, participants were recruited and randomly assigned to the control and experimental conditions. The final sample included 533 participants. In the ‘Combination condition’, − 386 g (95% CI: − 579, − 193) meat was purchased compared with the ‘Control condition’. Compared to the ‘Control condition’ less meat was purchased in the ‘Price condition’ (− 144 g (95%CI: − 331, 43)), although not statistically significant, whereas a similar amount of meat was purchased in the ‘Information nudge condition’ (1 g (95%CI: − 188, 189)). Conclusion Achieving the most pronounced effects on reduced meat purchases will require a policy mixture of pricing and informational nudging. Less meat is purchased in a virtual supermarket after raising the meat price by 30% combined with an information nudge. The results could be used to design evidence-based policy measures to reduce meat purchases. Trial registration The trial was registered in the Netherlands Trial Register identifier NL8628.

Evaluation of foods, drinks and diets in the Netherlands according to the degree of processing for nutritional quality, environmental impact and food costs. BMC Public Health 2022; 22:877.

Abstract
OBJECTIVE This study investigates nutritional quality, environmental impact and costs of foods and drinks and their consumption in daily diets according to the degree of processing across the Dutch population. DESIGN The NOVA classification was used to classify the degree of processing (ultra-processed foods (UPF) and ultra-processed drinks (UPD)). Food consumption data were derived from the Dutch National Food Consumption Survey 2012-2016. Indicators assessed were nutritional quality (saturated fatty acids (SFA), sodium, mono and disaccharides (sugar), fibre and protein), environmental impact (greenhouse gas (GHG) emissions and blue water use) and food costs. SETTING The Netherlands. PARTICIPANTS Four thousand three hundred thirteen Dutch participants aged 1 to 79 years. RESULTS Per 100 g, UPF were more energy-dense and less healthy than unprocessed or minimally processed foods (MPF); UPF were associated with higher GHG emissions and lower blue water use, and were cheaper. The energy and sugar content of UPD were similar to those of unprocessed or minimally processed drinks (MPD); associated with similar GHG emissions but blue water use was less, and they were also more expensive. In the average Dutch diet, per 2000 kcal, ultra-processed foods and drinks (UPFD) covered 29% (456 g UPF and 437 g UPD) of daily consumption and 61% of energy intake. UPFD consumption was higher among children than adults, especially for UPD. UPFD consumption determined 45% of GHG emissions, 23% of blue water use and 39% of expenses for daily food consumption. UPFD consumption contributed 54% to 72% to daily sodium, sugar and SFA intake. CONCLUSIONS Compared with unprocessed or minimally processed foods and drinks, UPF and UPD were found to be less healthy considering their high energy, SFA, sugar and sodium content. However, UPF were associated higher GHG emissions and with less blue water use and food costs. Therefore daily blue water use and food costs might increase if UPF are replaced by those unprocessed or minimally processed. As nutritional quality, environmental impacts and food costs relate differently to the NOVA classification, the classification is not directly applicable to identify win-win-wins of nutritional quality, environmental impact and costs of diets.

Abstract
PURPOSE This study examined the association of social contexts and food preparation location with the quality of meals and snacks (predominately from the five food groups (FFG) versus discretionary foods) in a sample of young Australian adults (18-30 years old) using wearable camera technology. METHODS A sub-sample from the cross-sectional MYMeals study wore a wearable camera that captured images every 30 s for three consecutive days. Eating episodes from 133 participants (55% female) were classified across 4 domains: food quality (observed proportion of FFG and discretionary items), preparation location, social interaction, and screen use. Socio-economic status (SES) was assigned using residential postcode and gender self-reported. Associations of contexts and demographic factors with food quality stratified by meal type were determined using mixed binary logistic regression models. RESULTS Of the 1840 eating episodes identified, 1775 were included in analysis (n = 8 preparation location and n = 57 food components that could not be identified were excluded). Food prepared at home was more likely to be from the FFG at lunch (OR = 4.8 95% CI 2.7-8.6), dinner (OR = 14.8 95% CI 7.6-28.6), and snacks (OR = 3.2 95% CI 2.2-4.8). Participants from higher SES areas were more likely to consume breakfasts (OR = 3.2 95% CI 1.4-7.4) and lunches (OR = 1.9 95% CI 1.0-3.7) predominately from the FFG. Females were more likely to consume lunches (OR = 2.0 95% CI 1.1-3.8) that was largely from the FFG. Social interaction and screen use were not associated with meal or snack quality. CONCLUSION Wearable cameras have verified the importance of addressing meals and snacks prepared outside of home as an important contributor of discretionary food.

Abstract
Few Australians consume diets consistent with the Australian Dietary Guidelines. A major problem is high intake of discretionary food and drinks (those not needed for health and high in saturated fat, added sugar, salt and/or alcohol). Low socioeconomic groups (SEGs) suffer particularly poor diet-related health. Surprisingly, detailed quantitative dietary data across SEGs was lacking. Analysis of the most recent national nutrition survey data produced habitual intakes of a reference household (two adults and two children) in SEG quintiles of household income. Cost and affordability of habitual and recommended diets for the reference household were determined using methods based on the Healthy Diets Australian Standardised Affordability and Pricing protocol. Low SEGs reported significantly lower intakes of healthy food and drinks yet similarly high intakes of discretionary choices to high SEGs (435 serves/fortnight). Total habitual diets of low SEGs cost significantly less than those of high SEGs (AU$751/fortnight to AU$853/fortnight). Results confirmed low SEGs cannot afford a healthy diet. Lower intakes of healthy choices in low SEGs may help explain their higher rates of diet-related disease compared to higher SEGs. The findings can inform potential policy actions to improve affordability of healthy foods and help drive healthier diets for all Australians.

Tartary Buckwheat: A New Plant-Based Ingredient to Enrich Corn-Based Gluten-Free Formulations. Foods 2021; 10:foods10112613.

Abstract
Tartary buckwheat is a pseudocereal receiving increasing attention as a minor crop interesting for agrobiodiversity conservation and sustainability. It is rich in bioactive substances which, however, may lead to sensory properties undesirable to the consumer, such as bitterness and astringency. The aim was to evaluate consumers' perception and overall liking of food products enriched with tartary or common buckwheat. A total of 120 consumers (56% women) aged 20-60 years (mean age ± SD: 38.8 ± 13.0 years) evaluated six samples of a corn-based gluten-free formulation enriched by increasing concentrations (20%, 30%, 40%) of either common (CB) or tartary buckwheat (TB) flour for overall liking and appropriateness of sensory properties. Results showed significant differences (p < 0.0001) in liking among samples. Considering all subjects, liking decreased with the increase of tartary buckwheat additions, although TB20 and TB30 samples were well accepted and comparable to all CB samples. TB40 was the least liked product. Two clusters of consumers showing opposite behaviours according to liking were found. One cluster (30%) showed an increased liking with the increasing amount of tartary buckwheat. These results show that by keeping the concentration of tartary buckwheat up to 30%, it is possible to develop new products accepted by consumers.

Abstract
BACKGROUND Aboriginal and Torres Strait Islander Australians experience persistent health and social inequities. Chronic conditions, many of which are diet-related, are leading contributors to the burden of disease and health inequity in Australia. First Nations Peoples have the right to be involved in all policy decisions affecting them. This review aimed to synthesise Aboriginal and Torres Strait Islander Peoples' concerns and priorities about food and nutrition in order to inform policies to improve health equity. METHODS MEDLINE, CINAHL, Informit and Google Scholar were systematically searched to identify qualitative studies-published from January 2008-that included data from Aboriginal and/or Torres Strait Islander Peoples about their concerns and priorities related to food and nutrition. Data were extracted from included studies using a pre-determined template and study quality was assessed using the Aboriginal and Torres Strait Islander Quality Appraisal Tool. Qualitative findings were synthesised using inductive thematic analysis and categorised based on an ecological model of health. RESULTS Twenty-one studies were included. Key factors influencing food and nutrition were identified across all levels of the ecological framework. These included interpersonal and institutional racism, junk food availability and marketing, food accessibility and affordability, housing conditions, food knowledge and cooking skills, and connection to family and culture. CONCLUSIONS Documenting Aboriginal and Torres Strait Islander Peoples' lived experiences of the colonised food system is one step necessary for informing policy to tackle food and nutrition inequities. Based on existing qualitative research, food and nutrition policymakers should prioritise building a supportive food environment by focusing on self-determination; ensuring access to healthy, affordable food and safe housing; and by eliminating systemic racism.

Cost and Affordability of Healthy, Equitable and Sustainable Diets in Low Socioeconomic Groups in Australia. Nutrients 2021; 13:nu13082900. [PMID: 34445059 PMCID: PMC8402089 DOI: 10.3390/nu13082900] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/19/2021] [Accepted: 08/19/2021] [Indexed: 11/16/2022] Open
Abstract
Few Australians consume a healthy, equitable and more sustainable diet consistent with the Australian Dietary Guidelines (ADGs). Low socioeconomic groups (SEGs) suffer particularly poor diet-related health problems. However, granular information on dietary intakes and affordability of recommended diets was lacking for low SEGs. The Healthy Diets Australian Standardised Affordability and Pricing protocol was modified for low SEGs to align with relevant dietary intakes reported in the National Nutrition Survey 2011–2012(which included less healthy and more discretionary options than the broader population), household structures, food purchasing habits, and incomes. Cost and affordability of habitual and recommended diets of low SEGs were calculated using prices of ‘standard brands’ and ‘cheapest options’. With ‘standard brands’, recommended diets cost less than habitual diets, but were unaffordable for low SEGs. With ‘cheapest options’, both diets were more affordable, but recommended diets cost more than habitual diets for some low SEGs, potentially contributing to perceptions that healthy food is unaffordable. The study confirms the need for an equity lens to better target dietary guidelines for low SEGs. It also highlights urgent policy action is needed to help improve affordability of recommended diets.

Affordability of current, and healthy, more equitable, sustainable diets by area of socioeconomic disadvantage and remoteness in Queensland: insights into food choice. Int J Equity Health 2021; 20:153. [PMID: 34193163 PMCID: PMC8243618 DOI: 10.1186/s12939-021-01481-8] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Accepted: 05/25/2021] [Indexed: 12/20/2022] Open
Abstract
Background Poor diet is the leading preventable risk factor contributing to the burden of disease globally and in Australia, and is inequitably distributed. As the price of healthy foods is a perceived barrier to improved diets, evidence on the cost and affordability of current (unhealthy) and recommended (healthy, more equitable and sustainable) diets is required to support policy action. Methods This study applied the Healthy Diets ASAP (Australian Standardised Affordability and Pricing) methods protocol to measure the cost, cost differential and affordability of current and recommended diets for a reference household in Queensland, Australia. Food prices were collected in 18 randomly selected locations stratified by area of socioeconomic disadvantage and remoteness. Diet affordability was calculated for three income categories. Results Surprisingly, recommended diets would cost 20% less than the current diet in Queensland as a whole. Households spent around 60% of their food budget on discretionary choices (that is, those not required for health that are high in saturated fat, added sugar, salt and/or alcohol). Queensland families would need to spend around 23% of their income on recommended diets. However, recommended diets would not be affordable in low socioeconomic or very remote areas, costing 30 and 35% of median household income respectively. The government supplements due to the SARS-CoV-2 pandemic would improve affordability of recommended diets by 29%. Conclusions Study findings highlight that while price is one factor affecting consumer food choice, other drivers such as taste, convenience, advertising and availability are important. Nevertheless, the study found that recommended diets would be unaffordable in very remote areas, and that low-income families are likely experiencing food stress, irrespective of where they live in Queensland. Policy actions, such as increasing to 20% the current 10% tax differential between basic healthy, and unhealthy foods in Australia, and supplementing incomes of vulnerable households, especially in remote areas, are recommended to help improve diet equity and sustainability, and health and wellbeing for all.

Abstract
Excessive free-sugar intake has become highly prevalent in numerous countries, and Portugal is not the exception. One product category that contributes to the daily intake of free sugars is breakfast cereals. In the current work, we identified 289 exemplars from two major retailers in Portugal and collected information on their nutritional profile (e.g., sugar, salt, fiber per 100 g), price, packaging features, type of food claims present (e.g., statements about the composition, sensory features, the origin of the product), and ingredients list. Overall, the sugar content of breakfast cereals was high (Mean = 19.9 g), and less than 10% of the products complied with the current national guidelines (i.e., 5 g of sugar per 100 g of product). Sugar (or other sugar sources) was listed in the top three ingredients for over 85% of the products. On average, each product included about four claims (Mean = 3.9), and sugar content was lower when the claims were related to the product composition. Critically, the sugar content was particularly high for children-oriented products (Mean = 26.4 g). Correlation analysis showed that breakfast cereals with higher sugar content also were cheaper and had lower quantities of fiber, proteins, and salt. Our findings suggest the need to implement strategies to reduce sugar in this product category (e.g., incentivize manufacturers to reformulate products). Also, our results may inform strategies aimed at promoting consumers' awareness about the sugar content in breakfast cereals and other processed foods, facilitating healthier decision-making.

Abstract
Poor dietary practices are commonly reported in working populations from different economic sectors, resulting in increased absenteeism and a decrease in productivity. The aims of this study were to describe the frequency of food consumption and diet quality in workers aged ≥16 years from 2006 to 2017 in Spain and to evaluate the factors associated with diet quality. A nationwide cross-sectional study was carried out among workers using data from the Spanish National Health Surveys in 2006 (n = 11,068), 2011 (n = 7497) and 2017 (n = 8890). Sociodemographic, occupational, and health-related variables were used as well as diet quality data. A multiple linear regression was performed to determine the characteristics related to overall diet quality. The percentage of workers who consumed vegetables, at most, once or twice per week decreased from 2006 to 2017 (p < 0.001). A lower diet quality score was related to the consumption of tobacco and alcohol and being aged ≥25 years old, while a higher diet quality score was linked to being a woman, having Spanish nationality, receiving optimal perceived social support, being physically active in one's main occupation, doing leisure-time physical activity, and the type of contract.

Abstract
Background Low socioeconomic groups (SEGs) in Australia are less likely to consume diets consistent with the Australian Dietary Guidelines (ADGs) and suffer poorer health than the broader population. The unaffordability, or perceived high cost, of healthy diets may be a factor. Detailed data on the cost of habitually consumed diets is required in order to inform strategies to alleviate socioeconomic impacts on dietary intake. This systematic scoping review aims to identify the cost of the habitual dietary intake of low SEGs in Australia, in terms of the whole diet and its composite foods, in comparison to the cost in higher SEGs. Methods A systematic search of peer-reviewed literature since 2000 and key government and non-government organisation (NGO) websites was undertaken. Data were extracted, synthesised and analysed in relation to study populations, dietary cost assessment measures, socioeconomic measures, and dietary cost and affordability. Results The review identified four studies meeting inclusion criteria. Results confirmed that overall, low SEGs spend a lower amount, yet a higher proportion of household income, on food and drinks than higher SEGs. Quantitative comparison of the dietary costs between included studies was not possible due to difference in populations and study metrics. Costs of the habitual diet in these studies were not reported for ADG food groups, so did not allow for assessment of the healthfulness of the dietary intake or comparison with costs of recommended diets at food group level. Conclusions Existing research does not provide sufficiently granular data of the costs of habitual diets of low SEGs in comparison to higher SEGs or data in a form that can inform strategies and interventions to improve dietary intake and diet-related health of low SEGs in Australia. Future empirical health research requires more granular measures of habitual spending on ADG food groups across SEGs.

The Healthiness of Food and Beverages on Price Promotion at Promotional Displays: A Cross-Sectional Audit of Australian Supermarkets. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17239026. [PMID: 33287395 PMCID: PMC7729449 DOI: 10.3390/ijerph17239026] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 11/28/2020] [Accepted: 11/30/2020] [Indexed: 12/22/2022]
Abstract
Supermarket environments can strongly influence purchasing decisions. Price promotions are recognised as a particularly persuasive tactic, but the healthiness of price promotions in prominent in-store locations is understudied. This study compared the prevalence and magnitude of price promotions on healthy and unhealthy food and beverages (foods) displayed at prominent in-store locations within Australian supermarkets, including analyses by supermarket group and area-level socio-economic position. A cross-sectional in-store audit of price promotions on foods at key display areas was undertaken in 104 randomly selected stores from major Australian supermarket groups (Woolworths, Coles, Aldi and independents) in Victoria, Australia. Of the display space dedicated to foods with price promotions, three of the four supermarket groups had a greater proportion of display space devoted to unhealthy (compared to healthy) foods at each promotional location measured (end of aisles: 66%; island bins: 53%; checkouts: 88%). Aldi offered very few price promotions. Few measures varied by area-level socio-economic position. This study demonstrated that price promotions at prominent in-store locations in Australian supermarkets favoured unhealthy foods. Marketing of this nature is likely to encourage the purchase of unhealthy foods, highlighting the need for retailers and policy-makers to consider addressing in-store pricing and placement strategies to encourage healthier food environments.

Abstract
BACKGROUND The diet of young adults is poor, yet little is known about the relative importance of influences on healthy eating in a decision-making context. The aim of this exploratory study was to understand the relative ranking of influences on meal choices in young adults and to investigate interactions between meal preferences and demographic and health characteristics. METHODS Adults aged 18-30 years (n = 92, mean age: 23.9 (SD 3.4) years) completed an online discrete choice experiment. Participants were presented with 12 choice sets reflecting a typical weekday meal and were asked to choose between four meal options. Each meal consisted of a combination of five meal attributes (preparation time, cost, taste, familiarity and nutrition content) that each had three attribute levels. Data were analysed using conditional logit models. Subgroup analyses were performed by sex, education, income, weight status and meeting fruit and vegetable recommendations. RESULTS Comparing the highest and lowest attribute levels, meal preferences were higher for better taste (B = 0.38; 95% CI: 0.12, 0.63), familiarity (B = 0.37; 95% CI: 0.21, 0.54) and nutrition content (B = 1.11; 95% CI: 0.81, 1.41) and lower for increased preparation times (B = -0.33; 95% CI: - 0.53, - 0.12) and cost (B = -0.50; 95% CI: - 0.75, - 0.24). Nutrition content was the most important influence on meal choice. Cost was the second most important, followed by taste, familiarity and preparation time. Compared to males, females had a higher preference for better nutrition content, taste and familiarity and a lower preference for increased cost. Higher educated participants had a higher preference for better nutrition content, familiarity and taste compared to lower educated participants. Young adults who met recommendations for fruit and vegetable intake had a higher preference for better nutrition content compared to participants who did not meet recommendations. CONCLUSION Nutrition content was the most important influence on young adults' meal choices, followed by cost, taste, familiarity and preparation time. Preferences varied by demographics and health characteristics, suggesting that the focus of dietary interventions may benefit from being tailored to specific young adult groups.

Abstract
Addressing social disadvantages that lead to obesity should be a public health priority. Obesity prevalence among children and adolescents has reached a plateau in countries with high income but it continues rising in low-income and middle-income countries. In high-income countries, an elevated prevalence of obesity is found among racial and ethnic minority groups and individuals from disadvantaged socioeconomic backgrounds. In addition to classic socioeconomic status (SES) factors, like income, parental education, and occupation, recent publications have linked parental social disadvantages, such as minimal social network, non-traditional family structure, migrant status and unemployment, with obesogenic behaviors and obesity among children. Socio-ecological models of obesity in children can explain the influence of classic SES factors, social disadvantages, culture, and genes on behaviors that could lead to obesity, contributing to the elevated prevalence of obesity. Obesity is a multifactorial disease in which multilevel interventions seem to be the most effective approach to prevent obesity in children, but previous meta-analyses have found that multilevel interventions had poor or inconsistent results. Despite these results, some multilevel interventions addressing specific disadvantaged social groups have shown beneficial effects on children's weight and energy balance-related behaviors, while other interventions have benefited children from both disadvantaged and non-disadvantaged backgrounds. Considering obesity as a worldwide problem, the World Health Organization, the European Commission, and the National Institutes of Health recommend the implementation of obesity prevention programs, but the implementation of such programs without taking into consideration social disadvantages may be an unsuccessful approach. Therefore, the present publication consists of a review of the pertinent literature related to social disadvantage and its consequences for behaviors that could lead to childhood obesity. In addition, we will discuss the relationship between social disadvantages and the socio-ecological model of obesity in children. Finally, we will summarize the relevant aspects of multilevel intervention programs aiming to prevent obesity in children and provide recommendations for future research and intervention approaches to improve weight status in children with social disadvantages.

Abstract
PURPOSE OF REVIEW The price of foods and beverages is a critical driver of food choice, particularly among families and households with limited food budgets. Policies targeting unhealthy food and beverage price promotions represent an untapped policy target for improving population diets and health. Here we review policy options for reducing the frequency and influence of price promotions on unhealthy foods and beverages (high in one or more of salt, sugar and saturated fat), and demonstrate their potential to complement other food policies and improve population diets. RECENT FINDINGS Price promotions on unhealthy foods and beverages are ubiquitous in many settings globally and appear to be more common than price promotions for healthy food. Shoppers appear to be more responsive to price promotions on unhealthy foods and beverages compared to price promotions for healthier items, with evidence that discounts lead to impulse purchases, stockpiling and overconsumption. A range of policy options exist to reduce the influence of price promotions on unhealthy foods and beverages, but none have been tested in the real world, meaning the industry and consumer responses to such policies are unclear. Policies that reduce the prevalence and influence of unhealthy food and beverage price promotions should be considered as part of a comprehensive approach to improving population diets.

Abstract
PURPOSE OF REVIEW Whilst evidence indicates that weight gain occurs over holidays, the contribution of specific festive periods and celebrations to eating behaviour and weight gain is unclear. We aimed to synthesise literature on how festive periods and celebrations contribute to population weight gain and weight-related outcomes. RECENT FINDINGS Thirty-nine studies examining (i) body weight changes, (ii) determinants of eating behaviour or (iii) weight-gain prevention interventions during festive periods were systematically reviewed. Of the 23 observational studies examining changes in body weight during festive periods, 70% found significant increases (mean 0.7 kg). Only four studies investigated exposure to food cues and overeating during these periods, with heterogeneous results. All six intervention studies found that weight gain can be mitigated by self-weighing/self-monitoring and intermittent fasting. Interventions targeting festive periods could have a significant impact on population weight gain. The scalability and sustainability of such interventions require further investigation, as do the broader socioecological factors driving unhealthy eating during festive periods.

Abstract
PURPOSE OF REVIEW Food and beverage prices are major influences on dietary intakes. International health bodies recommend leveraging food prices to create healthier food environments. A policy review was conducted to understand the extent to which national nutrition and obesity prevention policy strategies within high-income countries (i) consider food price as a determinant of health and (ii) propose and implement policies to rebalance food pricing towards healthier options. RECENT FINDINGS Policy strategies were inconsistent and fragmented in their inclusion of food prices as determinants of diet-related health. The equity benefits of pricing policies were often indicated. Fiscal measures and food subsidies in schools were the most commonly proposed and implemented pricing policies, predominantly used in Europe. Price is a pertinent but underutilized policy lever in nutrition policy. Comprehensive food and beverage pricing strategies need to be identified, adopted and implemented to improve population diets for everyone.

Abstract
PURPOSE OF REVIEW This review describes policy and regulatory strategies to prevent obesity and summarizes worldwide progress and impediments to scaling up strategies globally. RECENT FINDINGS While there is considerable variation in the breadth and depth of uptake of recommended strategies, the adoption of effective obesity prevention policies has been slow and inconsistent. There is broad consensus that strong government, corporate, and consumer actions, including regulatory measures, are needed to advance obesity prevention policies. Governments have lacked sufficient will to take necessary action, the food industry has actively worked to thwart policies to protect its commercial interests, and consumers have not exerted sufficient influence or demand to produce change. Advancing obesity prevention will require the use of effective strategies to shape and influence the information environments and political environments towards messages and actions to support public health. Greater emphasis is needed on reducing the influence of commercial interests, mobilizing civil society, and targeting vulnerable populations through equity-focused frameworks.
