RESUMO

The aim of this study is to combine flaxseed oil (FO), rich in α-linolenic acid (ALA), with Sunite sheep tail fat (STF) through a lipase-catalyzed transesterification reaction, in order to produce an edible oil with a fatty acid ratio suitable for human needs. Initially, the optimal conditions for esterification were determined using the Box-Behnken design, with the measurement criterion being the content of ALA at the sn-2 position. The results indicated that the highest content of sn-2 ALA was obtained under the conditions of using 6.8 wt% Lipozyme®RMIM as the catalyst, a reaction temperature of 57°C, a reaction time of 3.3 h, and a substrate mass ratio of 5.6:4.4 for STF and FO. This led to the rapid breaking and recombining of molecular bonds, resulting in the interesterified fat (IF) with the highest content of ALA at the sn-2 position. Comparing STF and FO, IF exhibited excellent fatty acid composition and content. Furthermore, IF had a lower melting point and crystallization temperature compared to STF, and its solid fat content decreased with increasing temperature, completely melting at temperatures above 30°C. Thus, IF is a synthesized fat with excellent properties from both animal and vegetable sources.

RESUMO

This cross-sectional study investigated the relationship between the use of food barcode scanner app (FBSA) and orthorexia, diet and emotions. A total of 1610 women from the general population were included in this study, 388 of whom were FBSA users. Participants completed questionnaires assessing socio-demographic and health characteristics, food barcode scanner use (Food Barcode Scanner App Questionnaire), orthorexia (Teruel Orthorexia Scale), food choice motivations (Food Choice Questionnaire), health anxiety (Health Anxiety Questionnaire), and emotional competence (Profile of Emotional Competence). The results showed no difference in socio-demographic characteristics between FBSA users and FBSA non-users. However, FBSA users scored higher on healthy orthorexia and health anxiety than non-users. FBSA users' food choice motivations were also more focused on natural food content, health, weight control and ethical concerns than non-users. Although no difference was found between FBSA users and non-users for orthorexia nervosa, orthorexia nervosa and pathological FBSA use scores were positively correlated. Moreover, health anxiety scores were positively correlated with FBSAQ "pathological use" subscale. While FBSA use may promote the adoption of a healthy diet, vigilance is required for individuals with orthorexic symptoms and health concerns. These two dimensions could be risk factors for problematic FBSA use.

RESUMO

BACKGROUND: Acute Coronary Syndrome is the most common heart disease and the most significant cause of death and disability-adjusted life years worldwide. Teaching a healthy eating style is one preventive measure to prevent the disease's recurrence. This study aimed to determine the effect of healthy nutrition education with the help of traffic light labels on food selection, preference, and consumption in patients with acute coronary syndrome. METHODS: This randomized, single-blinded clinical trial was conducted with 139 participants (66 in the intervention group and 73 in the control group) from January 2021 to August 2021 in Shaheed Rajaie Hospital, Tehran, Iran. The control group received standard training. The intervention group, besides this, received additional bedside training with an educational poster on traffic light labels from the research team during their final hospitalization days. Data were collected using a researcher-made questionnaire on food selection, preference, and consumption. RESULTS: The Brunner-Munzel test showed no significant difference between the two groups in terms of selection (P = 0.127), preference (P = 0.852), and food consumption (P = 0.846) in the baseline, while after the intervention, there were significant differences in selection (P > 0.001), preference (P > 0.001), and consumption (p < 0.004). Comparing the difference between the two groups in the difference between the before and after scores for selection (p < 0.001), preference (p < 0.001), and food consumption (p = 0.011) with the Brunner-Munzel test indicated a significant difference in all outcome variables. CONCLUSIONS: Teaching healthy eating styles with the help of traffic light labels affected food selection, preference, and consumption and led to healthier diets in these patients. CLINICAL TRIAL REGISTRATION NUMBER: Clinical trial registration: It was prospectively registered in the Iran Clinical Trials Registration Center on this date 30/10/2020 (IRCT20200927048857N1).

RESUMO

(1) Background: Independently owned restaurants (IORs) are prevalent in under-resourced racial and ethnic minority communities in the US and present a unique setting for public health nutrition interventions. (2) Methods: We conducted 14 in-depth interviews with IOR owners in Baltimore about their perceptions of healthy food, and customers' acceptance of healthier menus and cooking methods and concurrent observations of the availability of healthy options on their menus. Qualitative data were coded and analyzed using ATLAS.ti. Observations were analyzed with statistical analysis performed in R. (3) Results: Owners perceived non-fried options, lean proteins, and plant-based meals as healthy. While open to using healthier cooking fats, they had mixed feelings about reducing salt, adopting non-frying methods for cooking, and adding vegetables and whole grains to the menu, and were reluctant to reduce sugar in recipes and beverages. Only 17.5% of 1019 foods and 27.6% of 174 beverages in these IORs were healthy, with no significant differences in the healthfulness of restaurant offerings within low-healthy-food-access/low-income neighborhoods and those outside. (4) Conclusion: Healthy options are generally scarce in Baltimore's IORs. Insights from owners inform future interventions to tailor healthy menu offerings that are well-received by customers and feasible for implementation.

RESUMO

Introduction: This cross-sectional study aimed to assess Online food delivery applications (OFDA) usage trends among adolescent users in the United Arab Emirates (UAE), focusing on their perceptions of healthy food options and food safety (n = 532). Methods: Sociodemographic information, frequency of OFDA use, factors affecting food choices, and perceptions of healthy food and food safety were investigated. A total perception score was calculated for each participant. Results: Most participants used OFDAs weekly (65.4%), favoring fast food (85.7%). Factors like appearance and price drove food choices (65.0%), while taste and cost hindered healthy food orders (29.7 and 28.2%). Younger and frequent users had lower scores for perceiving healthy food, while seeking healthy options was associated with higher scores (p < 0.05). Females and those seeking healthy food showed higher food safety scores (p < 0.05). Discussion: The study suggests tailored interventions to promote healthier choices and improve food safety perceptions among adolescents using OFDAs in the UAE.

RESUMO

AIMS: An increase in psychosomatic symptoms among adolescents has recently been reported. Few studies have examined the relation between food intake and psychosomatic symptoms. The aim was to study the association between food intake and overall psychosomatic burden and separate psychosomatic symptoms. METHODS: In this cross-sectional study, we used data from 6248 girls and 7153 boys in south-east Sweden who turned 16 years of age during the academic years 2009/2010 to 2015/2016 and responded to a health questionnaire at the school health services. The association between overall healthy food intake and a low psychosomatic burden was calculated as odds ratios (95% confidence interval) and stratified for other lifestyle habits and gender. RESULTS: Sixty-nine per cent of the boys and 35% of the girls had a low psychosomatic burden. There was a positive association between an overall healthy food intake and a low psychosomatic burden (P<0.0001), regardless of other lifestyle habits and gender. An overall healthy food intake was also positively associated with a lower frequency of the separate psychosomatic symptoms of concentration difficulties, sleep difficulties, a poor appetite or dizziness (P<0.0001). CONCLUSIONS: A healthy food intake seems to be associated with a low psychosomatic burden among adolescents. Further knowledge is needed to explore whether an improved food intake can reduce psychosomatic symptoms and enhance mental health.

RESUMO

OBJECTIVE: To assess the selection of foods and beverages in children's sports arenas in Norway. DESIGN: A cross-sectional study design with a digital questionnaire was used. Descriptive statistics were used to present the results. Moreover, Pearson's χ2 tests examined the factors that could aid in distinguishing clubs with healthy or unhealthy consumables. SETTING: Children's sports clubs in Norway. PARTICIPANTS: Representatives from 301 children's sports clubs in Norway answered the questionnaire between September and November 2021. RESULTS: In total, 89·4% of the participating sports clubs (n 301) offered soda drinks with sugar. Most of the sports clubs (88 %) reported to offer batter-based cakes such as pancakes and waffles and 63·8 % offered cakes. Furthermore, 47·5% sold hot dishes with processed meat, such as hamburgers and hot dogs. More than 80% of the sports clubs offered sweets and snacks, while 44·5% did not offer fruits, vegetables and/or berries. Notably, the important factors that distinguished sports clubs with healthier food selections from those with unhealthier selections were the presence of guidelines for the food offered and purchase agreements with food suppliers. CONCLUSIONS: Educational, governmental guidelines for the promotion of healthy eating and establishing agreements with suppliers of healthier foods could help to overcome barriers to unhealthy food selection.

RESUMO

Background: High sodium and low potassium intake are positively associated with blood pressure, a significant risk factor for cardiovascular disease. The mean intake of sodium among United States adults exceeds the chronic disease risk reduction level of 2300 mg/d, whereas potassium intake remains lower than the recommended levels. From 2008 through 2019, there were several local and national initiatives to reduce sodium in New York City (NYC). Objectives: We aimed to update and compare estimates of sodium intake among NYC adults overall and by covariates from the 2010 Heart Follow-Up Study (HFUS) with the 2018 HFUS. We also estimated the 2018 sodium-to-potassium ratio to understand overall diet quality among demographic groups. Methods: This cross-sectional study used sodium and potassium measurements from 24-h urine collection and self-reported data from 2509 and 1656 participants in the 2018 and 2010 HFUS, respectively. The weighted mean daily intake of sodium and the sodium-to-potassium ratio were estimated. T-tests and multivariable linear regression models with tests for interactions were used to compare changes in sodium intake. Results: The mean sodium intake of adult New Yorkers in 2018 was 3292 mg/d. Sodium intake did not change from 2010 (3234 mg/d, P = 0.45) to 2018 in the overall population, although there was a decrease in sodium intake among adults 18-24 y old (3445 mg/d to 2957 mg/d, P = 0.05). The daily mean sodium-to-potassium ratio was 1.7 mg/mg. The highest sodium-to-potassium ratios were among Black females 18-44 y old (2.0) and 45-64 y old (2.2) and Black (2.1) and Latino (2.1) males between 18 and 44 y old. Conclusions: The lack of population-level changes in sodium intake and the high sodium-to-potassium ratios among Black females and younger Black and Latino males suggest that further efforts to reduce sodium in the food supply and address persistent inequities are needed.

RESUMO

While biomedical understandings of food and diet coupled with discourses on individual responsibility towards healthy food choices are nowadays prominent, other social and cultural meanings attached to food and diet are largely devalued. The limits of such a reductionist approach are more evident when related to the experiences of migrant and ethnic populations, whose alternative knowledge(s) and practices about food and health are especially neglected. A multicultural city with a public healthcare system inherited from the British colonial times and largely shaped by biomedical ideas of health, Hong Kong offers a lens into the limits of such a reductionist approach. Due to their vulnerability in the context of Hong Kong as shaped by intersecting social identities, 72 women from Pakistan were recruited to be our community partners in a community-based participatory action research project to investigate their health needs and concerns. 12 focus group discussions were conducted, exploring their experiences of "healthy" food and overweight especially related to their encounters with the Hong Kong public healthcare system, as these issues emerged as key health concerns within the community. Four major themes emerged: unmet expectations of care, health is beyond the individual, constraints to a healthy diet in the context of migration, and beyond health: food as care for diasporic women. This study highlights the limit of a reductionist approach to healthy food as merely based on nutrition and individual responsibility. It stresses the need of a counter-discourse in the field of public health, emphasizing not only alternative cultural ideas of health and food, but also enlarging the field of health in biomedical terms to embrace "care" and acknowledging the structural constraints shaping migrant and ethnic population's vulnerability in making "healthy" food choices.

RESUMO

OBJECTIVE: Different forms of public and private regulation have been used to improve the healthiness of food retail environments. The aim of this scoping review was to systematically examine the types of private regulatory measures used to create healthy food retail environments, the reporting of the processes of implementation, monitoring, review and enforcement and the barriers to and enablers of these. DESIGN: Scoping review using the Johanna Briggs Institute guidelines. Ovid MEDLINE, PsycINFO, Embase, CINAHL Plus, Business Source Complete and Scopus databases were searched in October 2020 and again in September 2023 using terms for 'food retail', 'regulation' and 'nutrition'. Regulatory measure type was described by domain and mechanism. Deductive thematic analysis was used to identify reported barriers and enablers to effective regulatory governance processes using a public health law framework. SETTING: Food retail. PARTICIPANTS: Food retail settings using private regulatory measures to create healthier food retail environments. RESULTS: In total, 17 694 articles were screened and thirty-five included for review from six countries, with all articles published since 2011. Articles reporting on twenty-six unique private regulatory measures cited a mix of voluntary (n 16), mandatory (n 6) measures, both (n 2) or did not disclose (n 2). Articles frequently reported on implementation (34/35), with less reporting on the other regulatory governance processes of monitoring (15/35), review (6/35) and enforcement (2/35). CONCLUSIONS: We recommend more attention be paid to reporting on the monitoring, review and enforcement processes used in private regulation to promote further progress in improving the healthiness of food retail environments.

RESUMO

OBJECTIVE: FoodRx is a 12-month healthy food prescription incentive program for people with type 2 diabetes (T2DM) and experiences of household food insecurity. In this study, we aimed to explore potential users' prospective acceptability (acceptability prior to program use) of the design and delivery of the FoodRx incentive and identify factors influencing prospective acceptability. DESIGN: We used a qualitative descriptive approach and purposive sampling to recruit individuals who were interested or uninterested in using the FoodRx incentive. Semi-structured interviews were guided by the theoretical framework of acceptability, and corresponding interview transcripts were analysed using differential qualitative analysis guided by the socioecological model. SETTING: Individuals living in Alberta, Canada. PARTICIPANTS: In total, fifteen adults with T2DM and experiences of household food insecurity. RESULTS: People who were interested in using the FoodRx incentive (n 10) perceived it to be more acceptable than those who were uninterested (n 5). We identified four themes that captured factors that influenced users' prospective acceptability: (i) participants' confidence, views and beliefs of FoodRx design and delivery and its future use (intrapersonal), (ii) the shopping routines and roles of individuals in participants' social networks (interpersonal), (iii) access to and experience with food retail outlets (community), and (iv) income and food access support to cope with the cost of living (policy). CONCLUSION: Future healthy food prescription programs should consider how factors at all levels of the socioecological model influence program acceptability and use these data to inform program design and delivery.

RESUMO

Nutrition is an important aspect of a healthy lifestyle for all individuals, including adolescents. The objective of this cross-sectional descriptive survey study was to investigate university students' awareness of immunity enhancing foods, food nutritive values, and eating practices during the COVID-19 pandemic. A total of 839 university students from four different universities in Pakistan participated in the study from October 2021 to January 2022, 397 of which were male and 442 were female. A total of 419 students were studying in medical disciplines while 420 were non-medical students. The students had significant knowledge (p < 0.05) about COVID-19, and nutritional habits were seen in both medical and non-medical students. Results showed that medical students (n-201) were slightly more aware of immunity-enhancing foods and the nutritive values of foods compared to engineering students (n-79). However, eating practices were generally poorly adopted by all of the university students. Male and female students were not significantly different in their mean replies to questions on the nutritive value of food or in their eating habits. Healthy eating practices will aid university students in preventing illnesses connected to nutrition as well as enhancing their immune systems and nutritional well-being both during and post-pandemic. In light of these results, suggestions and implications for nutritional advice and education were explored.

RESUMO

Stress increases the likelihood of consuming unhealthy food in some individuals. Previous research has demonstrated that the Regulation of Craving - Training (ROC-T) intervention can reduce unhealthy food intake. However, its effectiveness under stress and the underlying mechanism remained uncertain. This study aimed to assess the efficacy of the ROC-T intervention in improving healthy food choices and to explore the intervention mechanism through computational modeling employing the hierarchical drift-diffusion model (HDDM). This study adopted a 2 (ROC-T intervention vs. control) * 2 (stress vs. no-stress) between-subject experimental design. A total of 118 employees (72 women, Mage  = 28.74) participated in the online experiment. Results show that the ROC-T intervention increases healthy food choices under stress and no-stress conditions. The HDDM results reveal a significant two-way interaction for non-decision time (Bayes factor, BF = 32.722) and initial bias (BF = 27.350). Specifically, in the no-stress condition, the ROC-T intervention resulted in lower non-decision time and higher initial bias compared with the control group. The findings validated the negative impact of stress on healthy food choices, and that the ROC-T intervention promotes healthy food choices both under stress and no-stress conditions.

RESUMO

Tetramethoxyflavones (TMFs) found in the Citrus genus have garnered considerable interest from food scientists and the health food industry because of their promising biological properties. Nonetheless, there are currently limited data available regarding the effectiveness and bioavailability of "hydroxylated TMFs", which are flavones known for their potential in disease prevention through dietary means. This study aims to provide insights into the chemical and biological properties of hydroxylated TMF and evaluates its effects on intestinal cell permeability and cytochrome P450 (CYP) inhibition. Liquid chromatography-mass spectrometry (LC-MS) and microsomes analyze the TMFs and hydroxylated TMFs, elucidating cell penetration and metabolic inhibition potential. 3H7-TMF shows the fastest (1-h) transport efficiency in intestinal cells. The Caco-2 cell model exhibits significant transport and absorption efficiency. Dissolved hydroxyl-TMF with hydrophilicity possibly permeates the gut. 3H7-TMF has higher transport efficiency (46%) 3H6-TMF (39%). IC50 values of TMFs (78-TMF, 57-TMF, 3H7-TMF, 3H6-TMF) against CYP enzymes (CYP1A2, CYP2D6, CYP2C9, CYP2C19, CYP3A4) range from 0.15 to 108 µM, indicating potent inhibition. Hydroxyl groups enhance TMF hydrophilicity and membrane permeability. TMFs display varied inhibitory effects due to hydroxyl and methoxy hindrance. This study underscores the strong CYP inhibitory capabilities in these TMFs, implying potential food-drug interactions if used in medicines or supplements. These findings can also help with food nutrition improvement and pharma food developments through innovative approaches for Citrus waste valorization.

RESUMO

BACKGROUND AND AIM: Dietary diversity index is a useful evaluation index for examining the role of dietary pattern in predicting chronic diseases risk, including non-alcoholic fatty liver disease(NAFLD). In the present study, we aimed to examine the possible association of dietary diversity using US Healthy Food Diversity(US HFD) index and the NAFLD risk in Iranian adults. METHODS: A total of 675 individuals (225 patients with NAFLD and 450 controls) aged 20-60 years were recruited for the current case-control study. Data on dietary intakes were determined using a validated food frequency questionnaire, and dietary diversity was calculated using the US HFD index. In patients with NAFLD, an ultrasound scan of the liver was used to detect NAFLD. Logistic regression models were used to estimate the odds ratios(ORs) and 95 % confidence interval(CI) of NAFLD across tertiles of the US HFD index. RESULTS: Mean ± SD age of the study population were 38.13 ± 8.85 years. The median (interquartile) score of the US HFD index in patients with NAFLD and healthy subjects was 0.08(0.07-0.09) and 0.09(0.08-0.10), respectively. In the age and sex-adjusted model, the odds of NAFLD were considerably reduced across tertiles of the US HFD index (OR:0.48; 95%CI:0.32-0.72, Ptrend<0.001). Also, in the final model, after adjusting for age, sex, waist-to-hip ratio, smoking, physical activity, marital status, socioeconomic status, and energy intake, the odds of NAFLD were significantly reduced across tertiles US HFD index (OR:0.55; 95%CI:0.31-0.97, Ptrend<0.001). Furthermore, for each SD increase in the US HFD index, the odds of NAFLD are reduced by 23 % (OR:0.77;95%CI:0.60-0.97,P-Value<0.001). CONCLUSIONS: Our findings revealed that greater adherence to dietary pattern with a high US HFD score, defined by higher intakes of fruits, vegetables, whole grains, legumes, nuts, low-fat dairy, seeds, soya products, and plant oils may be related to reducing the odds of NAFLD.

RESUMO

OBJECTIVE: To investigate adolescents' experiences with the food selection at the sport arena. DESIGN: Four focus group interviews were conducted with 4-6 participants each. Interviews were recorded and transcribed verbatim. The transcripts were coded in NVivo and the analysis was guided by thematic analysis. SETTING: Adolescents from handball and football clubs in Oslo and Viken, Norway, participated in the study. PARTICIPANTS: A total of nine boys (11-14 years old) and ten girls (11-14 years old) participated in the study. RESULTS: We identified four main themes: interest for healthy food; experiences with the food selection at the sports arena; factors influencing participants' food choices at the sports arena and expectations related to a healthy food selection at the sports arena. Adolescents across the focus groups experienced the food selection at the sports arena as unhealthy. Price, marketing and availability of unhealthy food were important factors that influenced their food choices at the sports arena. The trainer appeared to motivate the participants to eat healthy. CONCLUSIONS: Participants wished for a healthier food selection at the sports arena. Cost of food emerged as a factor that influenced their food choices. Our study also indicates that marketing of unhealthy food and beverages should be restricted, to influence adolescence food choice towards healthier alternatives.

RESUMO

CONTEXT: Many countries and institutions have adopted policies to promote healthier food and drink availability in various settings, including public sector workplaces. OBJECTIVE: The objective of this review was to systematically synthesize evidence on barriers and facilitators to implementation of and compliance with healthy food and drink policies aimed at the general adult population in public sector workplaces. DATA SOURCES: Nine scientific databases, 9 grey literature sources, and government websites in key English-speaking countries along with reference lists. DATA EXTRACTION: All identified records (N = 8559) were assessed for eligibility. Studies reporting on barriers and facilitators were included irrespective of study design and methods used but were excluded if they were published before 2000 or in a non-English language. DATA ANALYSIS: Forty-one studies were eligible for inclusion, mainly from Australia, the United States, and Canada. The most common workplace settings were healthcare facilities, sports and recreation centers, and government agencies. Interviews and surveys were the predominant methods of data collection. Methodological aspects were assessed with the Critical Appraisal Skills Program Qualitative Studies Checklist. Generally, there was poor reporting of data collection and analysis methods. Thematic synthesis identified 4 themes: (1) a ratified policy as the foundation of a successful implementation plan; (2) food providers' acceptance of implementation is rooted in positive stakeholder relationships, recognizing opportunities, and taking ownership; (3) creating customer demand for healthier options may relieve tension between policy objectives and business goals; and (4) food supply may limit the ability of food providers to implement the policy. CONCLUSIONS: Findings suggest that although vendors encounter challenges, there are also factors that support healthy food and drink policy implementation in public sector workplaces. Understanding barriers and facilitators to successful policy implementation will significantly benefit stakeholders interested or engaging in healthy food and drink policy development and implementation.

RESUMO

BACKGROUND: Nutrient profiling systems (NPSs) use algorithms to evaluate the nutritional quality of foods and beverages. Criterion validation, which assesses the relationship between consuming foods rated as healthier by the NPS and objective measures of health, is essential to ensure the accuracy of NPSs. OBJECTIVE: We examined and compared NPSs that have undergone criterion validity testing in relation to diet-related disease risk and risk markers. METHODS: Academic databases were searched for prospective cohort and cross-sectional studies published before November, 2022. NPSs were eligible if they incorporated multiple nutrients or food components using an algorithm to determine an overall summary indicator (e.g., a score or rank) for individual foods. Studies were included if they assessed the criterion validity of an eligible NPS. Validation evidence was first summarized in narrative form by NPS, with random effects meta-analysis where ≥2 prospective cohort studies assessed the same NPS and outcomes. RESULTS: Of 4519 publications identified, 29 describing 9 NPSs were included in the review. The Nutri-Score NPS was assessed as having substantial criterion validation evidence. Highest compared with lowest diet quality as defined by the Nutri-Score was associated with significantly lower risk of cardiovascular disease (hazard ratio [HR]: 0.74; 95% confidence interval [CI]: 0.59, 0.93; n = 6), cancer (HR: 0.75; 95% CI: 0.59, 0.94; n = 5), all-cause mortality (HR: 0.74; 95% CI; 0.59, 0.91; n = 4) and change in body mass index (HR: 0.68; 95% CI: 0.50, 0.92; n = 3). The Food Standards Agency NPS, Health Star Rating, Nutrient Profiling Scoring Criterion, Food Compass, Overall Nutrition Quality Index, and the Nutrient-Rich Food Index were determined as having intermediate criterion validation evidence. Two other NPSs were determined as having limited criterion validation evidence. CONCLUSIONS: We found limited criterion validation studies compared with the number of NPSs estimated to exist. Greater emphasis on conducting and reporting on criterion validation studies across varied contexts may improve the confidence in existing NPSs.

RESUMO

BACKGROUND: The British Columbia Farmers' Market Nutrition Coupon Program (BC FMNCP) provides households with low incomes with coupons to purchase healthy foods from farmers' markets. OBJECTIVE: To examine the impact of the BC FMNCP on the short-term household food insecurity, malnutrition risk, mental well-being, sense of community (secondary outcomes), and subjective social status (exploratory outcome) of adults with low incomes post-intervention and 16 weeks post-intervention. DESIGN: Secondary analyses from a pragmatic randomized controlled trial conducted in 2019 that collected data at baseline, post-intervention, and 16 weeks post-intervention. PARTICIPANTS/SETTING: Adults ≥18 years with low incomes were randomized to an FMNCP group (n = 143) or a no-intervention control group (n = 142). INTERVENTION: Participants in the FMNCP group received 16 coupon sheets valued at $21 Canadian dollars (CAD)/sheet over 10 to 15 weeks to purchase healthy foods from farmers' markets and were eligible to participate in nutrition skill-building activities. MAIN OUTCOME MEASURES: Outcomes included short-term household food insecurity (modified version of Health Canada's 18-item Household Food Security Survey Module), malnutrition risk (Malnutrition Universal Screening Tool), mental well-being (Warwick-Edinburgh Mental Well-Being Scale), sense of community (Brief Sense of Community Scale), and subjective social status (MacArthur Scale of Subjective Social Status community scale). STATISTICAL ANALYSIS: Mixed-effects linear regression and multinomial logistic regression examined between-group differences in outcomes post-intervention and 16 weeks post-intervention. RESULTS: The risk of marginal and severe short-term household food insecurity was lower among those in the FMNCP group compared with those in the control group (relative risk ratio [RRR] 0.15, P = 0.01 and RRR 0.16, P = 0.02) post-intervention, with sustained reductions in severe household food insecurity 16 weeks post-intervention (RRR 0.11, P = 0.01). No statistically significant differences were observed in malnutrition risk, mental well-being, sense of community, or subjective social status post-intervention or 16 weeks post-intervention. CONCLUSIONS: The BC FMNCP reduced short-term household food insecurity but was not found to improve malnutrition risk or psychosocial well-being among adults with low incomes compared with a no-intervention control group.

RESUMO

Introdução: Favelas são regiões que não foram priorizadas pelas políticas públicas, e isso se reflete no ambiente alimentar e, consequentemente, na dificuldade de acesso aos alimentos, sobretudo aqueles produzidos de forma sustentável. Objetivo: Caracterizar o acesso físico às feiras de orgânicos municipais em favelas de Belo Horizonte, Minas Gerais, identificando desertos e pântanos alimentares e realizando uma comparação com a disponibilidade, distância e tempo de deslocamento de estabelecimentos que ofertam alimentos convencionais nessas áreas. Métodos: Foi analisada a distribuição das feiras de orgânicos municipais, dos equipamentos públicos de segurança alimentar e nutricional e dos estabelecimentos que ofertam alimentos cadastrados na Secretaria da Fazenda do Estado de Minas Gerais para o ano de 2019, nos 192 setores censitários localizados em favelas de Belo Horizonte. Para as análises closestfacility e distância de deslocamento, foi utilizado o buffer network de 500 metros. Também foi realizada a análise do tempo de deslocamento utilizando transporte público. Resultados: As feiras de orgânicos municipais estão em menor número e mais distantes dos centroides das favelas. E, além da maior distância para acessar as feiras caminhando, acessá-las por meio de transporte público leva, em geral, um tempo maior de deslocamento. Conclusões: São necessários programas e políticas públicas que incentivem a abertura de feiras de orgânicos e outros tipos de estabelecimentos que ofertam alimentos in natura e minimamente processados que adotem modelos de produção sustentáveis em áreas de favelas, a fim de reduzir as iniquidades de acesso aos alimentos saudáveis e sustentáveis nesse território.Introdução: Favelas são regiões que não foram priorizadas pelas políticas públicas, e isso se reflete no ambiente alimentar e, consequentemente, na dificuldade de acesso aos alimentos, sobretudo aqueles produzidos de forma sustentável.

Introduction: Favelas are usually in regions forgotten by public policies, and it reflects on their residents' food environment, as well as on their tough time accessing food, mainly produced through sustainable ways. Objective: Featuring the physical access to municipal organic-food fairs in Belo Horizonte City, Minas Gerais State, based on identifying food deserts and swamps and comparing food availability to distance and displacement time from shops that sell conventional food in these places. Methods: The distribution of organic food municipal fairs, as well as of both food security and nutrition public equipment, and shops selling food that was registered at Minas Gerais State Treasure Secretariat in 2019, located in the 192 census sectors set in Belo Horizonte favelas. The closest facility and displacement distance analyses were based on the 500m buffer network. Displacement time linked to public transportation usage was also analyzed. Results: The number of organic food municipal fairs in favelas is smaller, and favelas are located farther from fairs' centroids. The distance to be crossed to get to fairs on foot in favelas is also longer, and getting to them by public transportation often demands longer displacements. Conclusions: Public programs and policies are needed to encourage new organic fairs and other establishment types capable of providing fresh and minimally processed food in favela areas based on sustainable production models. It must be done to reduce inequities in access to healthy and sustainable food in these territories.
