Food safety and nutrition for low-income urbanites: exploring a social justice dilemma in consumption policy

Fruit and Vegetable Intake of Females Before, During, and After Introduction of 3 Bundled Food System Interventions in Urban Vietnam and Nigeria

Background

Low fruit and vegetable (FV) intake in low- and middle-income countries, which is associated with noncommunicable diseases and micronutrient deficiencies, requires food system interventions addressing FV accessibility, affordability, and acceptability. Periodic FV intake monitoring during interventions informs progress toward achieving increased intakes and contributes to understanding the effectiveness of these interventions.

Objectives

This study evaluates the trend in FV intake before, during, and after implementation of a set of nutrition-sensitive food system interventions addressing accessibility, affordability, and acceptability to increase FV consumption over a 1-y period in Vietnamese and Nigerian low-income urban and periurban females.

Methods

We used the Diet Quality Questionnaire to assess FV food group consumption among 600 Vietnamese (Hanoi) and 610 Nigerian (Ibadan) females before, during, and after the interventions (Vietnam: July 2020-September 2021; Nigeria: November 2020-December 2021). A FV score was compared between exposure groups with (mixed) count modeling. The trend in consumption of individual FV groups was analyzed with mixed logistic regression.

Results

The FV score was stable over time, and a small increase was observed after the intervention period especially in Nigeria and in urban Vietnam. A decrease in the total score was observed in periurban Vietnam. Fluctuations were detected in the probability of consumption of individual FV groups over time especially within the fruit groups, probably due to seasonal availability. The degree of exposure could not explain differences in FV intake.

Conclusions

We found a marginal increase in the proportion of females consuming FV during the interventions in both countries. The FV score appeared to be a simple, quick, and easy-to-use indicator for monitoring diversity, variety, and consumption.

Does livestock ownership predict animal-source food consumption frequency among children aged 6-24 months and their mothers in the rural Dale district, southern Ethiopia?

Background

Animal-source foods are food items that come from animals. Animal-source foods provide a variety of micronutrients that plant-source foods cannot provide to the same extent and without extra precaution. Milk, eggs, poultry, flesh meat and fish are animal-source foods mainly used in Ethiopia. Low animal-source food consumption among children and mothers is a great concern in many low-income settings. This study aimed to describe animal-source food consumption frequencies among children aged 6-24 months and their mothers in rural southern Ethiopia where livestock farming is very common. We also analysed the association between livestock ownership and animal-source food consumption among children and mothers.

Methods

A community-based cross-sectional study was conducted among 851 randomly selected households with child-mother pairs from August to November 2018. The study was conducted in the rural Dale District, southern Ethiopia. Structured and pre-tested questionnaires were used to collect data on mother and child information, livestock ownership, and animal-source foods consumption frequencies. Ordinal logistic regression analysis was used to describe associations between animal-source foods consumption and livestock ownership.

Result

Nearly, three-quarters (74.1%) of the households owned cows, and a quarter (25%) had goats or sheep. Dairy, egg and meat consumption among children during the past month was 91.8%, 83.0% and 26.2%, respectively. Likewise, the consumption of dairy, eggs and meat among mothers was 96.0%, 49.5% and 34.0%, respectively. The percentage of children who had not consumed any animal-source foods during the month prior to our survey was 6.6%, and the figure was 2.2% for the mothers. Dairy consumption was 1.8 times higher among children (aOR = 1.8, 95% CI [1.3-2.5]) and 3.0 times higher among mothers (aOR = 3.0, 95% CI [2.2-4.2]) in households that kept cows than in households without cows. The egg consumption frequency was positively associated with hen and goat/sheep ownership for both children and mothers. Meat consumption frequency among children was negatively associated with cow ownership (aOR = 0.66, 95% CI [0.45-0.95]); however, cow ownership was not associated with meat consumption among mothers.

Conclusion

Dairy products were common animal-source foods consumed by young children and mothers in the study area. However, meat consumption was low among children and mothers. Strategies like promoting the keeping of goats/sheep and hens to improve complementary feeding and mothers' nutrition are warranted in the study area.

Ultraprocessed Foods and Cancer in Low-Middle-Income Countries

Low middle income countries (LMICs) are the predominant contributors to global cancer-related mortality and are projected to bear the greater share of the global cancer burden in the next few decades. Among other factors, lifestyle changes have been linked to the rising incidence of cancer in these countries. As one of the keys to a healthy lifestyle, a balanced diet plays a major role in the preservation of health. Globalization and rapid urbanization have prompted a paradigm shift in various aspects of daily life in LMICs; the influence on dietary choices has been particularly noticeable. Studies show a concerning rise in the sale and consumption of ultraprocessed foods in these countries. In addition to hyperpalatability, this trend has been attributed to various other factors including convenience, availability, economic considerations, and marketing strategies. Although several studies from LMICs recognize and recommend the need for effective public health measures to reduce the consumption of these foods, findings from certain studies suggest that established public health strategies occasionally fail in the real-world scenario. Barriers to effective policymaking also contribute to the prevailing dietary trends. This review of studies from the LMIC setting demonstrates the current problem, limitations of established public health measures, and the complexities associated with effective policymaking. In view of the threat posed to cancer risk, there is an urgent need to curb the consumption of ultraprocessed foods in LMICs. National policymakers therefore need to circumnavigate the challenges effectively to ensure timely achievement of the United Nations sustainable development goals.

Quantitative assessment of aflatoxin exposure and hepatocellular carcinoma (HCC) risk associated with consumption of select Nigerian staple foods

Aflatoxin contamination of staple grains and legumes has been linked to hepatocellular carcinoma (HCC) and other adverse health outcomes, constituting a substantial public health concern globally. Low-resource food environments in sub-Saharan Africa are often under-regulated and are particularly vulnerable to adverse health and nutrition outcomes associated with aflatoxin exposure. This study identifies levels of HCC risk in the northern Nigerian adult population, leveraging a systematic review of available evidence on aflatoxin contamination in Nigerian maize, groundnut, rice, cowpea, and soybean. Estimated dietary intake (EDI) was computed using publicly available dietary consumption data and a probabilistic quantitative risk assessment was conducted to determine the relative risk of HCC associated with consumption of selected aflatoxin-contaminated commodities. In total, 41 eligible studies reporting aflatoxin contamination were used to model the distribution of aflatoxin concentrations in Nigerian commodities. EDIs for maize, groundnut, rice, and cowpea exceeded the provisional maximum tolerable daily intake (PMTDI) level of 1 kgbw-1 day-1, with maize yielding the highest mean EDI (36.7 kgbw-1 day-1). The quantitative risk assessment estimated that 1.77, 0.44, 0.43, 0.15, and 0.01 HCC cases per year/100,000 population were attributable to aflatoxin exposure through maize, groundnut, rice, cowpea, and soybean, respectively. Sensitivity analysis revealed that aflatoxin concentration, dietary consumption levels, consumption frequency, and other variables have differing relative contributions to HCC risk across commodities. These findings constitute a novel multi-study risk assessment approach in the Nigerian context and substantiate existing evidence suggesting that there is reason for public health concern regarding aflatoxin exposure in the Nigerian population.

A home gardening intervention to improve vegetable consumption among urban poor children: A study protocol for randomised controlled trial

Background: One of the key importance of vegetable consumption is to obtain sufficient micronutrients, dietary fibre, and for the prevention of childhood obesity. Most Malaysian children did not meet the recommended intake of vegetable consumption, and this is especially vulnerable among the urban poor population due to food insecurity. Efforts are needed to promote vegetable consumption that fall short of the recommended intake level. Aim: This trial aims to examine the effectiveness of the "GrowEat" project, as a nutrition intervention programme integrated with home gardening activities to improve vegetable consumption among urban poor children in Kuala Lumpur, Malaysia. Methods: This is a single-blinded parallel two-arm cluster randomised controlled trial (RCT) that include 134 children. Two zones in Kuala Lumpur will be randomly selected, and three low-cost housing flats from each zone will be selected as the intervention and control groups respectively. The trial is designed based on the social cognitive theory (SCT). Children from the intervention group (n = 67) will attend a 12-week programme, which consists of home garden-based activities, gardening and nutrition education session. Assessment will be conducted for both groups at three time points: baseline, post-intervention and follow-up phase at 3 months after the intervention. Conclusion: We anticipate positive changes in vegetable consumption and its related factors after the implementation of the "GrowEat" project. The current intervention may also serve as a model and can be extended to other urban poor population for similar interventions in the future to improve vegetable consumption, agriculture and nutrition awareness.

How Perspectives on Food Safety of Vendors and Consumers Translate into Food-Choice Behaviors in 6 African and Asian Countries

Background

Consumption of unsafe foods increases morbidity and mortality and is currently an issue, particularly in low- and middle-income countries. Policy actions to ensure food safety are dominated by mitigation of biological and chemical hazards through supply-side risk management, lessening the degree to which consumer perspectives of food safety are considered.

Objectives

This study aimed to provide an in-depth understanding, from vendor and consumer perspectives, of how food-safety concerns of consumers translate into their subsequent food-choice behaviors in 6 diverse low- and middle-income countries.

Methods

Six Drivers of Food Choice projects (2016-2022) provided transcripts from 17 focus group discussions and 343 interviews conducted in Ghana, Guinea, India, Kenya, Tanzania, and Vietnam. Qualitative thematic analysis was used to identify emerging themes important to food safety.

Results

The analysis suggests that consumers constructed meaning about food safety through personal lived experience and social influences. Community and family members contributed knowledge about food safety. Concerns about food safety were influenced by reputations of and relationships with food vendors. Consumers' mistrust of food vendors was amplified by purposeful adulteration or unsafe selling practices and new methods used to produce food. Moreover, consumers were reassured of food safety by positive relationships with vendors; meals cooked at home; implementation of policies and following regulations; vendor adherence to environmental sanitation and food-hygiene practices; cleanliness of vendors' appearance; and vendors' or producers' agency to use risk mitigation strategies in production, processing, and distribution of food.

Conclusions

Consumers integrated their meanings, knowledge, and concerns about food safety to achieve assurance about the safety of their foods when making food-choice decisions. The success of food-safety policies hinges on consideration of consumers' food-safety concerns in their design and implementation, alongside actions to reduce risk in food supply.

Evaluation of irish consumers' knowledge of salmonellosis and food-handling practices

Salmonella is one of numerous food-borne pathogens that could possibly pose a major threat to global food safety. Salmonella is primarily associated with foods such as poultry, eggs, vegetables, and some dairy products. However, infected food handlers and faecal contaminated environments are also significant sources and reservoirs of this pathogen. This study comprehensively evaluated the Irish consumers' food safety knowledge by exploring their knowledge level, practices and attitudes regarding raw meat handling, cross-contamination while handling different types of food products, and knowledge of Salmonella risk and associated food-handling practices. The online SurveyMonkey tool was used to distribute a quantitative survey titled "Evaluation of Knowledge and Food-handling practices of Irish Consumers" from July to November 2020 and generated a total of 1916 responses. Results indicated that 79.9% of the studied Irish population had a good knowledge of salmonellosis and risk perception related to food handling practices. Knowledge of cross-contamination, hygienic practices and pathogens associated with poultry were also considered high. However, knowledge of meat handling was low at 44.9%. It was also observed that age, gender, marital status, gross annual income, and nationality were influential factors regarding the food safety knowledge of consumers, while age, marital status and gender indicated significant differences regarding awareness of correct food hygiene practices.

Effects of COVID-19 on dietary behavior of urban consumers in Nairobi, Kenya

The disruptions wrought by the COVID-19 pandemic on food systems worldwide have endangered food and nutrition security for many consumers. The resource-poor, especially those in urban areas, are more susceptible to pandemic-related disturbances. This study uses primary data collected from 2,465 households located in and outside of informal settlements (slums) in Nairobi, Kenya to assess how COVID-19 and related public-health measures have influenced diets of urban consumers, their purchasing patterns and overall food security. Questions about food security and consumption behavior, including household dietary diversity scores, were used to capture the pre- and mid-pandemic situation. The data show that low-income households in the informal settlements were more affected than middle-income households. About 90% of slum households reported dire food insecurity situations, including being unable to eat preferred kinds of food, eating a limited variety of foods, consuming smaller portions than they felt they needed, and eating fewer meals in a day. With a score of four food groups out of nine, household in the informal settlements have lower dietary diversity than middle-income households, whose score is five out of nine. The consumption of nutritious foods, including fruits, vegetables, and animal products, fell among people living in slums during the pandemic. In addition to assessing dietary changes, this study highlights the factors associated with quality food consumption during the pandemic period such as household income levels and male-vs-female headed households. Our research demonstrates the need to attend to slums and vulnerable, poor consumers when enacting mitigation measures or designing and implementing policy.

The influence of food environments on dietary behaviour and nutrition in Southeast Asia: A systematic scoping review

Background: Food environments are crucial spaces within the food system for understanding and addressing many of the shared drivers of malnutrition. In recent years, food environment research has grown rapidly, however, definitions, measures, and methods remain highly inconsistent, leading to a body of literature that is notably heterogeneous and poorly understood, particularly within regions of the Asia-Pacific. Aim: This scoping review aims to synthesize the nature, extent, and range of published literature surrounding the role of the food environment on influencing dietary behaviour and nutrition in Southeast Asia. Methods: A systematic search of 5 databases was conducted following PRISMA guidelines for scoping reviews. Eligible studies included peer-reviewed research with adult participants living in Southeast Asia that examined the food environment as a determinant of dietary behaviour or nutrition. Results: A total of 45 articles were included. Overall, studies indicated that dietary behaviours in Southeast Asia were primarily driven by social, cultural, and economic factors rather than physical (e.g. geographical) features of food environments. Food price and affordability were most consistently identified as key barriers to achieving healthy diets. Conclusion: This work contributes to the establishment of more robust conceptualizations of food environments within diverse settings which may aid future policymakers and researchers identify and address the barriers or obstacles impacting nutrition and food security in their communities. Further research is needed to strengthen this knowledge, particularly research that explicitly explores the macro-level mechanisms and pathways that influence diet and nutrition outcomes.

A risk-benefit approach to the purchase and consumption of conventional vegetables in wet markets

The purchase and consumption of conventional vegetables from wet markets in Vietnam are like two sides of a coin: perceived food safety risks and perceived benefits. Drawing on a sample of 463 Hanoi consumers, this study employed a risk-benefit approach to analyze the purchase intention and consumption frequency of conventional vegetables at traditional markets. A confirmatory factor analysis examined the links among risk perception, perceived utilitarian benefits, perceived hedonic benefits, and trust. Finally, generalized ordered and Poisson regressions were performed on these psychological constructs and their identified links. We found that perceived hedonic benefits, trust in wet market actors, and the presence of homegrown vegetables determined purchase intention and consumption frequency. The joint influence of perceived hedonic and utilitarian benefits on purchase intention implies that consumers considered both benefit dimensions when thinking of their future purchase of conventional vegetables. The significant interaction between perceived risk and perceived hedonic benefits on consumption frequency supports the risk-benefit approach. The effect of perceived hedonic benefits and income on purchase intention and consumption frequency are evidence of wet markets' social and cultural relevance.

Reimagining Food: Readdressing and Respecting Values

The values associated with food are framed and constructed by market-based systems that assign attributes to different foods across the marketplace. The aim of the paper was to conceptualize the range of non-financial aspects associated with food in the literature examined and a typology was introduced to position a new set of non-financial food values, the alter-values, which support the creation of a more holistic approach to visualize and reimagine a more sustainable, resilient food system that readdresses and respects such values. The four alter-values of interest, intrinsic, production-related, supply chain related, and emotio-cultural values, were discussed in the context of changing food environments, and a visualization of the typology was presented to explain them. By focusing especially on intrinsic and emotio-cultural values, an adaptation of the current food environment beyond pecuniary-based emphasis was possible. Such an approach helps to challenge the structure of the conventional food system towards a more citizen-driven sustainable model, altering priorities, with a drive towards embedding values and going beyond perceiving food only in terms of exchange value, to considering food as a vital aspect of life.

Social justice equity in healthy living medicine - An international perspective

Irrespective of geographical location, disadvantaged people are disproportionately affected by unnecessary disease and suffering caused by inequalities in health. Although equal access to opportunities for healthy living medicine regardless of legal, political, economic, or other circumstances should be a basic human right, it is increasingly improbable for scores of people, particularly in Africa, Asia, Latin America, and the Caribbean, to acquire this. In recent times, global initiatives have attempted to make 'healthy lifestyles' more equitable by pledging to be relevant to all economies, promoting prosperity, environmental protection, climate change interventions, and purposeful action to meet the needs of vulnerable populations, including women and children. Yet there remains much to be done to address and reduce the substantial international health equity gaps. Reducing disparities that disproportionately affect the lower end of social strata must entail collaborative and systemic action from important stakeholders across the whole system, an approach that translates theory and research into practice. Ideally, realist approaches that appreciate the importance of the context of problems and assume nothing works everywhere or for everyone, should be prioritised over linear/simple and non-scalable intervention strategies.

Why Home Gardens Fail in Enhancing Food Security and Dietary Diversity

Visions of sustainable cities mostly conjure up well tended home and community gardens, where owners and residents plant fruits and vegetables that supply some of their livelihood needs. Indeed, home gardens can contribute to household food security but often fail to do so. Moreover, gardens can provide several additional ecosystem services and impact entire communities. This paper seeks to answer why these gardens often do not provide adequate services to make a substantial contribution to food security and identifies possible solutions. We undertook a case study in South Africa in a low-income former township area. The area is characterized by poverty, high levels of unemployment and food insecurity. We interviewed 140 respondents with home gardens to determine what role their own garden plays in household food security. Only 10% of households were found to be completely food secure. Of the rest, 39% experienced hunger that affected everyone in the household and 51% were at risk of hunger. Despite the fact that 72% of the respondents planted vegetables or fruits, the gardens did not contribute substantially to food security. The respondents mostly bought their food, with subsequent food shortages when they did not have enough money. The dietary diversity and consumption of vitamin A-rich fruits and vegetables were very low. The most important constraints inhibiting urban agriculture in the study area were cultural practices, such as the presence of large, bare, open spaces, or “lebala,” the focus of home gardeners on ornamental species and lawns; and a reliance on purchasing of foods.

Informal ready-to-eat food vending: a social practice perspective on urban food provisioning in Nigeria

The way people access food in Nigeria is of central relevance for food security, health and sustainability. One key trend is the shift from household-based to primarily out-of-home food consumption as an increasing majority of the urban poor derive their daily nutrient intake from street foods. However, few studies have yet explored the role of the ready-to-eat food vending sector in urban food systems and the diets of the urban poor. This paper investigates the interrelations between these practices and the diversity of food groups provisioned among the urban poor in developing city contexts. A social practice approach is employed to explore differentiation among informal-ready-to-eat food vending practices in the city of Ibadan, Nigeria, in terms of their daily activities, competences and resources. Applied methods include GIS mapping, food log diaries, in-depth interviews and participant observation to map and classify informal-ready-to-eat food vending practices according to the nature of food provisioned and explore the everyday performances of different informal-ready-to-eat food vending practice initiatives and their relation to dietary diversity. The results reveal three key categories among these practices: traditional, processed and unprocessed—with varying levels of diversity in the food groups on offer. Traditional food vendors offer more diversified food compared to processed food vendors and unprocessed food vendors. The results reveal that material infrastructure, cooking bargaining and purchasing skills and nutritional knowledge are key to the diversity of food groups provisioned. The paper concludes by considering the wider relevance of these findings for urban food science and policy.

Exploring supply chain issues affecting food access and security among urban poor in South Africa

Purpose

Access to food through retail supply chain distribution can vary significantly among the urban poor and leads to household food insecurity. The paper explores this sustainable supply chain phenomenon through a field study among South Africa's urban poor.

Design/methodology/approach

Urban metabolic flows is the theoretical basis in the context of supply chain management (SCM). The field study comprised 59 semi-structured interviews in one South African township. Data were recorded, transcribed and translated, and coded using NVivo 12 to provide an inventory of eight themes categorized and patterned from the analysis.

Findings

Findings indicate societal factors play a significant role affecting food distribution, access and security from a spatial perspective of retail outlet locations and a nutritional standpoint regarding quality and quantity of food.

Research limitations/implications

The study is exploratory in one township, and while rigorously conducted, the generalizability of findings is limited to this context.

Practical implications

The study practically contributes by providing guidance for food retailers and policymakers to include nutritional guidelines in their distribution planning, as well as the dynamics of diverse neighbourhoods that exist in modern urban contexts.

Social implications

New forms of retail food distribution can provide better security and access to food for the urban poor, contributing to Sustainable Development Goals (SDGs) 2 Zero Hunger and 11 Liveable Cities.

Originality/value

The study is interdisciplinary and contributes by linking UN SDGs and SCM through urban metabolic flows from development studies as an overarching framework to enable analysis of relationships between physical, social and economic factors in the urban environment.

Urban physical food environments drive dietary behaviours in Ghana and Kenya: A photovoice study

We identified factors in the physical food environment that influence dietary behaviours among low-income dwellers in three African cities (Nairobi, Accra, Ho). We used Photovoice with 142 males/females (≥13 years). In the neighbourhood environment, poor hygiene, environmental sanitation, food contamination and adulteration were key concerns. Economic access was perceived as a major barrier to accessing nutritionally safe and healthy foods. Home gardening supplemented household nutritional needs, particularly in Nairobi. Policies to enhance food safety in neighbourhood environments are required. Home gardening, food pricing policies and social protection schemes could reduce financial barriers to safe and healthy diets.

Consumer perceptions of food safety in animal source foods choice and consumption in Nairobi's informal settlements

Background

Animal-source foods (ASFs) are high-quality nutrient-dense products key to reducing stunting and micronutrient deficiencies. However, their consumption among the poorest households in urban informal settlements is low. Several drivers beyond price, including health considerations have been reported to drive ASF choice and consumption among consumers. This current study explores consumer perceptions of food safety associated with animal source foods (ASFs) consumption in urban informal settlements with a view to unpacking the health considerations driving their choice and consumption.

Methods

Coupled households with children 6–59 months formed the study sample. The Food Environments Working Group (FEWG) Framework of the Agriculture and Nutrition for Health academy (ANH) was used to guide the study which utilized qualitative methods namely, 60 in-depth interviews (IDIs), 19 focus group discussions, and 19 key informant interviews (KIIs) complemented by unstructured observations. Data were transcribed and analysed according to emerging themes.

Results

Consumer perceptions of food safety are driven by concerns about food production, processing, handling, storage and the health risks associated with consumption of the ASFs. For all the ASFs, lack of traceability of source, unhygienic environments in which they were sold and health risks around consuming too much or improperly cooked products were key perceptions from the community. To mitigate against food safety risks, consumers used strategies such as boiling the ASFs, purchasing their products from trusted retailers, avoiding vendors in unhygienic environments and reducing the amount and frequency of consumption of ASFs or totally avoiding their consumption.

These consumer perceptions are increasingly influencing the ASFs choice and consumption in low-income populations besides other drivers. Notably, given limited incomes that influence their purchasing power and the need for nutritious diets that included ASFs, the dilemma of quality vis-a-vis quantity persists and consumers still accessed and consumed these ASF products to supplement their diets.

Conclusions

To enhance food safety for ASFs, as well as assure consumer access to safe ASFs from informal markets, there is need to contextualize the value chain as informed by consumer perceptions on food safety as these influence their ASFs choice and consumption.

Negotiating Unsustainable Food Transformations: Development, Middle Classes and Everyday Food Practices in Vietnam

Amidst calls for making food systems more sustainable, new unsustainable food transformations unfold alongside economic development. Explanations for unsustainable food transformations in emerging economies vary greatly, but there is widespread agreement that demand from new middle classes play a crucial role. Yet this demand is to a large extent co-created by systems of provision, and middle-class consumers are constantly navigating food transformations in a search for healthy and safe food. Focusing on Vietnam's dramatic food transformations, and combining attention to the political economy of food with a social practice approach to consumption, the paper zooms in on the how middle-class households in Hanoi negotiate the rapid transformations of food systems and food environments. The paper concludes that new thinking on sustainable food systems is urgently needed and argues that vital insights can be gained by studying food practices and their interaction with everyday geographies of consumption.

Determining Food Stability to Achieve Food Security

Food security, as part as public health protection, constitutes one of the main objectives for countries aiming to ensure the health of all their citizens. However, food security is compromised worldwide by conflict, political instability, or economic crises, both in developed and developing countries. Conversely, because of the importance of agriculture to the economies of rural areas both in developed and developing countries, this sector can contribute to improving food stability, as well as to furthering food security. Thus, livestock and traditional meat products represent a key factor in ensuring food availability. Overall, biosecurity measures improve animal welfare by decreasing the occurrence of diseases that compromise the stability by causing fluctuations in the availability of meat and animal-derived food products such as milk, eggs, or traditional fermented products. As a consequence, an absence of biosecurity measures affects food security (in its quantitative definition, as described above) as well as the productive, sanitary, and environmental sustainability of the rural environment. Products of animal origin support local trade and the regional economy, while contributing to the availability of foods without great external dependence. The manufacture of foods of animal origin aims to create products that are durable and that maintain food availability for long periods of time, even during seasons with scarce resources. Thus, dry-cured or fermented meat products play an important role in food availability. Food security also refers to food access under healthy economic conditions; therefore, knowledge of the main tools that guarantee the safety of these kinds of food products is essential to achieving food stability and further food security.

Contextualizing the COVID-19 pandemic's impact on food security in two small cities in Bangladesh

The COVID-19 pandemic is an evolving urban crisis. This research paper assesses impacts of the lockdown on food security and associated coping mechanisms in two small cities in Bangladesh (Mongla and Noapara) during March to May 2020. Due to restrictions during the prolonged lockdown, residents (in particular low-income groups) had limited access to livelihood opportunities and experienced significant or complete loss of income. This affected both the quantity and quality of food consumed. Coping strategies reported include curtailing consumption, relying on inexpensive starchy staples, increasing the share of total expenditure allocated to food, taking out loans and accessing relief. The pandemic has exacerbated the precariousness of existing food and nutrition security in these cities, although residents with guaranteed incomes and adequate savings did not suffer significantly during lockdown. While coping strategies and the importance of social capital are similar in small and large cities, food procurement and relationships with local governments show differences.

Australian Consumers' Preferences for Food Attributes: A Latent Profile Analysis

Understanding consumer food preferences can provide agribusinesses with a competitive advantage through meeting consumers’ needs. Consumers’ preferences for food attributes have been extensively examined, focusing on specific aspects of attributes with specific food products. It is less clear how consumers evaluate the relative importance of the key food attributes in general. Applying the commonly adopted classification of food attributes into endogenous attributes (i.e., safety and freshness) and exogenous attributes (i.e., genetically modified (GM)-free and organic), the relative importance of these attributes for consumers was investigated. Furthermore, the heterogeneity of preferences was explored to identify distinct subgroups of consumers who may differ in valuing various food attributes. An online survey of 489 city dwellers in Australia revealed that the endogenous attributes were regarded as the most important in an order of safety and freshness. The exogenous attributes were rated as much less important. Three profiles with distinctive preferences for food attributes were identified: Not Fussy (12% of participants), Quality First (49%) and Choosy (39%). The findings suggest that consumers value the importance of various food attributes in a hierarchical order, and there is significant heterogeneity in consumers’ food preference. The implications of these findings are discussed in the context of food policy and agribusiness decision-making.

Understanding Vietnamese Urban Consumers' Nutrition Label Use, Health Concerns, and Consumption of Food and Beverages with Added Sugars

Vietnam is experiencing a diet and nutrition transition. Increasing consumption of food and beverages with added sugars is a significant public health concern. Policies and interventions, such as mandatory nutrition labelling, are being considered to improve consumers’ awareness and understanding of diet and health implications of added sugars in food and beverages. The effectiveness of various policy approaches relies on an improved understanding of the interrelationships between urban Vietnamese consumers’ health concerns, nutrition label use, and intake of sugars. We empirically disentangle these relationships for urban Vietnamese households using novel intra-household data covering 4047 adults and 737 adolescents from 1590 households in Hanoi and Ho Chi Minh City. The data are from comprehensive household surveys and 24-hour food diaries. Simultaneous equation regression models are estimated using three-stage least squares (3SLS) to account for possible endogeneity. Nutrition label use is significantly associated with a lower share of calories from foods and beverages with added sugars. These findings suggest that nutrition labelling programs may be an effective policy mechanism to reduce the negative health implications of increasing availability and consumption of food and beverages with added sugars in urban Vietnam.

Understanding food westernisation and other contemporary drivers of adult, adolescent and child nutrition quality in urban Vietnam

OBJECTIVE

To examine the association between consumption of western foods purchased and consumed away from home and measures of nutrition quality: average daily caloric intake and macronutrient (carbohydrates, fat and protein) shares, for urban consumers in Vietnam, a country undergoing economic transition.

DESIGN

Cross-sectional observational data were collected using household surveys and 24-h food diaries. Outcome variables were individual average daily caloric intake and shares of calories from macronutrients: carbohydrates, fat and protein. The key explanatory variable was individual daily share of calories from western food purchased and consumed away from home. Ordinary least squares and multivariate regression analyses were used to examine the association between the outcome variables: caloric intake and macronutrient shares and the share of calories from western food consumed away from home.

SETTING

Hanoi and Ho Chi Minh City in Vietnam.

PARTICIPANTS

In total, 1685 households and 4997 individuals, including adults (aged $$ \ge $$ 18 years), adolescents (aged 10-17 years) and children (aged 0-9 years).

RESULTS

The share of calories from western food away from home was significantly associated with higher caloric intake among male and female adults (P < 0·01), adolescents (P < 0·01) and male children (P < 0·10) and was associated with higher shares of fat for male and female adults (P < 0·01), adolescents (P < 0·01) and male children (P < 0·01).

CONCLUSIONS

Policymakers must be conscious of the numerous factors associated with poor nutrition quality, especially in younger Vietnamese individuals. Relevant interventions targeting at risk groups are required if nutrition improvement is a long-term goal.
