Exploration of school meal food service management: a case study of a full-day school

This research was aimed to capture the practice of foodservice management and food acceptance for change unbalance dietary intake children in a fullday Elementary School. School meal food service management is a program for students to improve the nutrition intake An observation form, along with an in-depth interview was used to explore food production practice. Quantitative data on food satisfaction as well as food waste was also measured. Observation in food service management explained that low food acceptance was mainly found in vegetable products. The food quality, especially in taste and texture, became the determinant of the high vegetable food waste. Improving food service management production procedures, including menu planning and evaluation, procurement, preparation, and cooking, could be a promising strategy to increase food acceptance and to reduce food waste.

Consumer awareness and production practices of farmers on antimicrobial residues in chicken eggs and Chinese cabbage in Dodoma, Central Tanzania.

BackgroundAntimicrobial residues (ABs) in foods contribute to the development of antimicrobial resistance, which is becoming a major public health concern around the world. Understanding food production practices concerning antimicrobial use and consumer awareness on the possibility of ABs in foods is necessary for developing mitigation strategies. Therefore, this study was conducted to assess the production practices and awareness among eggs and Chinese cabbage consumers in Dodoma city.MethodsA cross-sectional study was conducted using a structured questionnaire and checklist to collect data on awareness and production practices from 420 consumers, 30 chicken egg farmers, and 30 Chinese cabbage farmers in eight city wards.FindingsAbout 42% of consumers of eggs and Chinese cabbages were not aware of the likelihood of antimicrobial residues in these foods. The awareness was significantly influenced by the consumer’s educational level (p = 0.001) and geographical location (p = 0.045), with educated and urban consumers being 7.7 and 1.6 times more informed than their uneducated and peri-urban counterparts. Furthermore, the majority of chicken farmers raised more layers than broilers, and they all used antimicrobial drugs, mainly tetracycline and its variants, to treat and prevent diseases. The findings also revealed that many vegetable producers utilized wastes from animals treated with antimicrobials as manure to amend the soil.ConclusionIn a view of the findings, a considerable number of egg and Chinese cabbage consumers in Dodoma city were unaware on the likelihood of antimicrobial residues in these foods from their production practices. All chicken farmers utilized antimicrobial drugs mainly tetracycline and its derivatives, for the treatment and prevention of diseases while vegetable producers used wastes from animals treated with antimicrobials as soil manure. Therefore, initiatives to inform farmers and consumers about the possibility of antimicrobial residues in these foods and their related public health risks upon long-term consumption are strongly advised.

A review of the effects of COVID-19 on food waste.

The COVID-19 pandemic exposed significant vulnerabilities in systems of production and consumption. In particular, the economic and social implications of the pandemic highlighted the urgent need for more sustainable and less impactful practices of food production and consumption. Through a systematic literature review, this paper seeks to assess how the pandemic affected the phenomenon of food waste, with the aim of assessing whether the pandemic stimulated changes amongst food system actors, especially consumers. The findings indicate that consumers generally reported behavioural changes during the pandemic and claimed to have adopted sustainable practices that could contribute to reducing food waste. The results also reflect the rapid diffusion of practices such as food delivery during the pandemic, which requires further investigation in terms of its effects on the environment. Simultaneously, supply–demand shocks and disruptions were reported in the areas of production, processing, and retailing, suggesting the occurence of ripple effects. A call is made for greater resilience in the food system, through the adoption of sustainable and less impactful practices, supported by policy.

Exploring Conventional Economic Viability as a Potential Barrier to Scalable Urban Agriculture: Examples from Two Divergent Development Contexts

Urban Agriculture (UA) is the widespread practice of food production within available city space using non-commercial, commercial and hybrid production technologies. The economic viability of UA remains a concern among UA practitioners. To investigate UA’s viability; land, labour and distribution cost are analyzed, and margin and benefit–cost ratio (BCR) under vacant lot, rooftop/backyard and discretionary labour UA are calculated. We present a straightforward approach to gauge the economic viability of UA taking examples from 40 distinct locations of two divergent development contexts of Adelaide, South Australia and Kathmandu Valley, Nepal. UA seems potentially viable by selecting high-value crops in Adelaide but showed little chance of viability under low-value crop scenarios in both contexts. The high cost of land is shown to be the primary driver of cost for UA. Labour cost appears to be a critical difference between the two cities, being an important constraint for the economic viability in Adelaide, where the wage rate is high. To improve economic viability, the respective governments and planners should consider better ways to avail subsidised land through policy intervention and volunteer or subsidised labour arrangement mechanisms. Home food gardens accessing available land and labour as a discretionary/spare time activity with zero distribution cost may represent the best way to produce food without exceeding market costs in cities.

Molecular mechanisms associated with microbial biostimulant-mediated growth enhancement, priming and drought stress tolerance in maize plants

Microbial-based biostimulants are emerging as effective strategies to improve agricultural productivity; however, the modes of action of such formulations are still largely unknown. Thus, herein we report elucidated metabolic reconfigurations in maize (Zea mays) leaves associated with growth promotion and drought stress tolerance induced by a microbial-based biostimulant, a Bacillus consortium. Morphophysiological measurements revealed that the biostimulant induced a significant increase in biomass and enzymatic regulators of oxidative stress. Furthermore, the targeted metabolomics approach revealed differential quantitative profiles in amino acid-, phytohormone-, flavonoid- and phenolic acid levels in plants treated with the biostimulant under well-watered, mild, and severe drought stress conditions. These metabolic alterations were complemented with gene expression and global DNA methylation profiles. Thus, the postulated framework, describing biostimulant-induced metabolic events in maize plants, provides actionable knowledge necessary for industries and farmers to confidently and innovatively explore, design and fully implement microbial-based formulations and strategies into agronomic practices for sustainable agriculture and food production.

Education for Sustainability in the Agriculture and Livestock Sector: Educational Experience in Gibraltar Area (Spain)

Abstract If we are to attain a sustainable future, humanity will need to make drastic changes towards a life based on sustainability in all areas, especially in the economic sector, including food production. The task of educating for sustainability needs to include food producers (farmers and livestock breeders). This article describes an educational experience carried out within the framework of a proposal presented in the “Second Call for Grants to Promote University-Company Projects” at the Technological Campus of Algeciras (Spain). It consisted of conducting in-depth interviews with farmers and livestock breeders, identifying the practices in the daily management of their farms, and having them participate in an education and training event in which they shared their knowledge. It was not an easy task because food producers have systematically been attacked by currents of opinion that blame them for causing greenhouse gas emissions. We adopted an approach based on empathy and on encouraging sustainable food production practices.

Field-Effect Transistor-Based Biosensors for Environmental and Agricultural Monitoring.

The precise monitoring of environmental contaminants and agricultural plant stress factors, respectively responsible for damages to our ecosystems and crop losses, has nowadays become a topic of uttermost importance. This is also highlighted by the recent introduction of the so-called “Sustainable Development Goals” of the United Nations, which aim at reducing pollutants while implementing more sustainable food production practices, leading to a reduced impact on all ecosystems. In this context, the standard methods currently used in these fields represent a sub-optimal solution, being expensive, laboratory-based techniques, and typically requiring trained personnel with high expertise. Recent advances in both biotechnology and material science have led to the emergence of new sensing (and biosensing) technologies, enabling low-cost, precise, and real-time detection. An especially interesting category of biosensors is represented by field-effect transistor-based biosensors (bio-FETs), which enable the possibility of performing in situ, continuous, selective, and sensitive measurements of a wide palette of different parameters of interest. Furthermore, bio-FETs offer the possibility of being fabricated using innovative and sustainable materials, employing various device configurations, each customized for a specific application. In the specific field of environmental and agricultural monitoring, the exploitation of these devices is particularly attractive as it paves the way to early detection and intervention strategies useful to limit, or even completely avoid negative outcomes (such as diseases to animals or ecosystems losses). This review focuses exactly on bio-FETs for environmental and agricultural monitoring, highlighting the recent and most relevant studies. First, bio-FET technology is introduced, followed by a detailed description of the the most commonly employed configurations, the available device fabrication techniques, as well as the specific materials and recognition elements. Then, examples of studies employing bio-FETs for environmental and agricultural monitoring are presented, highlighting in detail advantages and disadvantages of available examples. Finally, in the discussion, the major challenges to be overcome (e.g., short device lifetime, small sensitivity and selectivity in complex media) are critically presented. Despite the current limitations and challenges, this review clearly shows that bio-FETs are extremely promising for new and disruptive innovations in these areas and others.

Effects of ozone air pollution on crop pollinators and pollination

Human driven environmental changes increase the concentrations of polluting reactive compounds in the troposphere, such as ozone and nitrogen oxides. These changes lead to biodiversity losses and alter plant physiology and plant-pollinator interactions, essential for pollination services, with potential consequences for agricultural production. Here we used 133 unique sampling events from NW Europe to investigate how air pollution (ozone and nitrogen oxides) and other sources of nitrogen is related to pollinator visitation rate and their contribution to agricultural production, also considering possible interactive effects with landscape quality and pesticide input. We showed that ozone modulates the effect of pesticide exposure and temperature on crop pollinators, increasing the probability of negative impacts on crop pollination. Indeed, when ozone levels are highest, the strength of the effect of pesticide on pollinators is more than double then when ozone levels are intermediate. This indicates that air pollution should be considered in management plans and policies aiming to safeguard biodiversity and promote more sustainable food production practices.

Qualitative evidence for improved caring, feeding and food production practices after nutrition-sensitive agriculture interventions in rural Vietnam

BackgroundResearch on nutrition-sensitive agriculture (NSA) has mostly been aimed at demonstrating its impact on nutrition and explicating underlying pathways, and more rarely at understanding processes and lessons learnt from them. This study aimed to gain insights into the processes that influence behaviour change, contributing to improved caring, feeding and food production practices, using a program theory perspective. It also investigated perceived challenges to the sustainability of interventions and potential solutions, in the context of an NSA program in rural Vietnam. Using a participatory approach, data were gathered on impact pathways and perceived outcomes, on elements of program theory that led to behavioural change, as well as barriers and facilitators. Respondents in semi-structured interviews (n = 30) and seven focus group discussions (total n = 76) were selected purposively among program participants. Data was collected and triangulated across several stakeholder groups.ResultsThe impact pathways (production-consumption, caring and feeding, and home-grown school feeding) envisaged in the NSA program functioned as intended; synergies were revealed. The increased supply of locally produced nutrient-rich foods not only contributed to the emergence of a promising income sub-pathway but also reinforced synergy with the home-grown school feeding pathway. Improved diets, feeding and caring practices, and school attendance were key outcomes of the program. Successful elements were pathway-specific, such as flexibility in implementing context-appropriate agricultural models. Others, such as benefit-driven motivation and improved knowledge, triggered changes in multiple pathways. Role models, increased self-confidence, and change agents were the main process facilitators. The biggest barrier to both implementation and sustainability was the poor socio-economic conditions of the most disadvantaged households.ConclusionsThis study showed the relevance of NSA programs in addressing undernutrition in remote areas by enhancing self-reliance in local communities. The integration of behaviour change activities proved to be a key strategy in the process to enhance the impact of agriculture on nutrition outcomes. Though outcomes and influencing factors are very context-dependent, lessons on what worked and what did not work could inform the design and implementation of effective behaviour change strategies in future NSA programs in Vietnam and elsewhere.

“An incredible voyage through Portugal” – the promotion of rural provenance foods by urban specialty shops

ABSTRACT This article analyzes how rural provenance foods are portrayed by the promotional materials, websites and social media issued by urban specialty stores in Portugal. Even though provenance food may be defined in multiple ways as, among others, local, regional, traditional, and authentic, provenance is mostly about territories of origin: their biophysical characteristics, cultural values and practices of food production and preparation with socioeconomic and historical features. Interest in and consumption of rural provenance foods have increased in the last few decades and more recently have been accompanied by a growth of specialty food stores in urban contexts. To analyze these stores’ role in promoting rural provenance foods, content analysis was conducted on 7489 text and image files, collected from the websites, social media pages and printed materials of 30 stores located in three Portuguese cities (Aveiro, Lisbon and Porto). Data shows that the role of these stores is not limited to the commercialization of food products, but is also key in the promotion and dissemination of their physical, sensorial and symbolic features as well as of the material and immaterial characteristics of their places of origin at local, regional and national scales.

Diet quality and exposure to endocrine-disrupting chemicals among US adults

Human exposure to endocrine-disrupting chemicals (EDCs) may increase risk for chronic disease. Diet is a significant source of EDC exposure, yet healthy diets recommended for chronic disease prevention have not been thoroughly examined for associations with EDC exposure. Using data from the National Health and Nutrition Examination Survey 2013–2016, we examined associations of dietary patterns with exposure to non-persistent EDCs potentially consumed through diet. EDCs were measured in spot urine samples. Diet was assessed using 24-h recalls. Multivariable linear regression was used to examine associations of three healthy diet scores [Healthy Eating Index (HEI), relative Mediterranean Diet (rMED), and Dietary Approaches to Stop Hypertension] and fast-food consumption with EDCs. In fully adjusted models, no diet was associated with exposure to the bisphenols, phthalates, or polycyclic aromatic hydrocarbons examined. A 1-point increase in rMED (of 18 possible points) was associated with 2.7% (95% CI: 1.7%, 3.8%) greater urinary nitrate. A 10-point increase in HEI (of 100 possible points) was associated with 5.3% (95% CI: 2.8%, 7.9%) greater nitrate and 6.8% (95% CI: 4.5%, 9.2%) greater perchlorate. Because perchlorate and nitrate can disrupt thyroid hormone production, we conducted an exploratory analysis to examine whether these chemicals mediate an association between diet and thyroid hormones. A 10-point increase in HEI was associated with 0.6% reduced serum total thyroxine (95% CI: 1.7%, 0.5%) among all adults, with 57.5% of the effect explained by perchlorate. Nitrate mediated an association of rMED with modestly reduced total triiodothyronine among females. Most EDCs examined had no association with the diets evaluated, indicating that recommended healthy diets were not protective against EDC exposures. As observed with two thyroid antagonists, some recommended diets may increase EDC exposures and related adverse health outcomes. Additional work should identify effective food production and processing practices to reduce dietary exposures to potentially harmful EDCs.

Performance Analysis of Dairy Farms Transitioning to Environmentally Friendly Grazing Practices: The Case Study of Santa Catarina, Brazil

The conflict between food production and environmental conservation demands alternative agriculture practices to maintain or increase food production, protect and restore critical ecosystem processes, and reduce dependence on non-renewable agricultural inputs. Deforestation in Brazil’s Atlantic Forest, for which agriculture has been a primary driver, already threatens the biome’s impressive biodiversity and the ecosystem services it helps sustain. Many small family farmers in Santa Catarina—located in the South of Brazil—have adopted the Voisin Rational Grazing System (VRG) as an alternative to conventional and environmentally detrimental dairy activities. This article presents the results of a research project designed to analyze the economic, social, and ecological VRG impacts based on farmers’ perceptions and economic accounts. We compare farmer profitability and critical social and environmental aspects of both systems using detailed interviews and monthly accounting of revenues and expenditures on VRG and conventional farms. We found that VRG is more profitable than the conventional dairy system in Santa Rosa de Lima. However, most farmers combine VRG with some conventional practices, affecting profitability and potential ecological benefits. The adoption of VRG in Santa Rosa de Lima nonetheless correlates with reduced use of environmentally harmful inputs, compatible with a gradual transition to a more ecologically-friendly and sustainable system.

Assessment of rapid low-cost isotope (δ15 N, δ18 O) analyses of nitrate in fruit extracts by Ti(III) reduction to differentiate organic from conventional production.

The isotopic composition (δ15 N, δ18 O) of nitrate in fruits and vegetables differentiates organic from conventional food production practices. Organic systems do not use synthetic nitrate fertilizers high in 18 O and low in 15 N and thereby help reveal producers' fertilization claims. Isotope analyses of nitrate extracted from fruits and vegetables are done by bacterial reduction which is costly and by specialized laboratories. Rapid, low-cost methods are needed to promulgate nitrate isotope analyses of food products to support organic food product certification and to verify the authenticity of production claims. Fresh strawberry samples were obtained from certified organic and conventional growers in Andalucía, Spain. We applied a new, rapid, one-step Ti(III) reduction method to convert the nitrate from strawberry extracts to N2 O gas for headspace isotope analyses using isotope-ratio mass spectrometry. Using the Ti(III) reduction method, 70 samples, controls and references were prepared and analyzed for NO3 - , δ15 N and δ18 O per 48 h. We also analyzed extracts and solids for anions and cations and for bulk δ15 N for multivariate chemometric evaluation. The Ti(III)-based isotope analyses of nitrate in strawberry extracts revealed clear differentiation between organic and conventional production with mean δ18 O and δ15 N values of +18.3 ± 1.2 ‰ and +17.6 ± 1.2 ‰ versus +28.2 ± 4.5 ‰ and +14.9 ± 3.0 ‰, respectively. The δ15 N of strawberry dry mass differed slightly (+3.0 ± 1.4 ‰ versus +4.0 ± 1.4 ‰) between organic and conventional samples, respectively. Chemometric analyses of nitrate isotopes and extract chemistry revealed that the δ18 O of nitrate along with δ15 N and Ca2+ fully differentiated organic from conventional strawberry production. Our results show the Ti(III) reduction method provides a new low-cost and rapid analytical method to facilitate compound-specific δ15 N and δ18 O isotope analyses of nitrate in selected fruit types, and likely other food products, for the purposes of assessing nitrate fertilization practices of organic versus conventional production claims and to support authenticity investigations.

Local practices and production confer resilience to rural Pacific food systems during the COVID-19 pandemic

Resilience of food systems is key to ensuring food security through crisis. The COVID-19 pandemic presents an unprecedented shock that reveals varying levels of resilience of increasingly interconnected food systems across the globe. We contribute to the ongoing debate about whether increased connectivity reduces or enhances resilience in the context of rural Pacific food systems, while examining how communities have adapted to the global shocks associated with the pandemic to ensure food security. We conducted 609 interviews across 199 coastal villages from May to October 2020 in Federated States of Micronesia, Fiji, Palau, Papua New Guinea, Solomon Islands, Tonga, and Tuvalu to understand community-level impacts and adaptations during the first 5–10 months of the COVID-19 crisis. We found that local food production practices and food sharing conferred resilience, and that imported foods could aid or inhibit resilience. Communities in countries more reliant on imports were almost twice as likely to report food insecurity compared to those least reliant. However, in places dealing with a concurrent cyclone, local food systems were impaired, and imported foods proved critical. Our findings suggest that policy in the Pacific should bolster sustainable local food production and practices. Pacific states should avoid becoming overly reliant on food imports, while having measures in place to support food security after disasters, supplementing locally produced and preserved foods with imported foods when necessary. Developing policies that promote resilient food systems can help prepare communities for future shocks, including those anticipated with climate change.

Factors influencing consumption of traditional diets: stakeholder views regarding sago consumption among the indigenous peoples of West Papua

BackgroundThe indigenous people living in the province of West Papua may experience potential food insecurity, in part attributable to increased local adoption of, and reliance on, imported foods such as rice. At the same time, the consumption of sago, a traditional local food, is lower than other types of carbohydrate foods such as wheat and cassava. Various factors may act as influential drivers of local diets and related agricultural practices, such as local socio-economic and agronomic factors, as well as cultural practices which in turn may be influenced by the attitudes and opinions of stakeholders with interests in the supply chain.MethodsQualitative methodology (semi-structured interviews) was applied to understand the various factors perceived by a selected number of stakeholders that influence sago consumption among the indigenous peoples of West Papua. These stakeholders included politicians, local and national civil servants, academics, sago farmers, and food activists (n = 18). Thematic analysis was used to analyse the data.ResultsThe results indicate that the stakeholders perceive that the majority of the West Papuan people regard sago as a traditional food that is critical to, and inseparable from, local culture and food production practices. The results suggest that the stakeholders interviewed support the consumption of sago to improve food security for the indigenous people in West Papua, with a need for future policy to be developed to support this.ConclusionsThe evidence presented here suggests a diverse range of local stakeholders support the continuation of sago production and consumption, both from the perspective of improved food security, and in order to conserve cultural associations and activities within local communities. According to the stakeholders interviewed, this can be best achieved through improved engagement of local communities with sago production policies, innovation in current practices, and agronomic management. Local policies should be developed to ensure that sago remains an integral component of the Papuan people's culture, and develops into a significant commodity with economic value which simultaneously contributes to environmental targets.

Achieving the Social Wellbeing Through Urban Horticulture Practices for Food Production and Security: A Comprehensive Review of Perception-Based Studies

Achieving the Social Wellbeing Through Urban Horticulture Practices for Food Production and Security: A Comprehensive Review of Perception-Based Studies

Who’s eating pork? Investigating pig breeding and consumption in Byzantine, Islamic and Norman/Aragonese Sicily (7th-14th c. AD)

This paper investigates the culture of pork consumption in Sicily by examining a number of archaeological faunal assemblages dated to chronological phases spanning from the Byzantine to the Norman/Aragonese period (7th-14th c. AD). Zooarchaeological analyses reveal substantial diachronic changes in the use of the main domesticates, particularly concerning pig frequencies. In the Islamic period (9th-11th c. AD), pig is poorly represented at urban sites; this is likely to reflect a socio-cultural acceptance of the Islamic religious precepts forbidding pork consumption. By contrast, and in continuity with the Roman and Byzantine periods, pigs are well-represented in rural settlements, thus indicating a more resilient attitude of these communities toward newly imported religious traditions. In the later Norman/Aragonese period, the frequency of pig increases at some urban sites, reflecting the fact that that pork prohibition had been lifted and that new food production and consumption practices were developed. Pig continues, however, to be almost absent at a number of urban sites and castles/fortified villages; this may suggest the persistence of Islamised communities in Sicily after the end of Islamic rule.

A Global Metabolic Map Defines the Effects of a Si-Based Biostimulant on Tomato Plants under Normal and Saline Conditions.

The ongoing unpredictability of climate changes is exponentially exerting a negative impact on crop production, further aggravating detrimental abiotic stress effects. Several research studies have been focused on the genetic modification of crop plants to achieve more crop resilience against such stress factors; however, there has been a paradigm shift in modern agriculture focusing on more organic, eco-friendly and long-lasting systems to improve crop yield. As such, extensive research into the use of microbial and nonmicrobial biostimulants has been at the core of agricultural studies to improve crop growth and development, as well as to attain tolerance against several biotic and abiotic stresses. However, the molecular mechanisms underlying the biostimulant activity remain enigmatic. Thus, this study is a liquid chromatography-mass spectrometry (LC-MS)-based untargeted metabolomics approach to unravel the hypothetical biochemical framework underlying effects of a nonmicrobial biostimulant (a silicon-based formulation) on tomato plants (Solanum lycopersium) under salinity stress conditions. This metabolomics study postulates that Si-based biostimulants could alleviate salinity stress in tomato plants through modulation of the primary metabolism involving changes in the tricarboxylic acid cycle, fatty acid and numerous amino acid biosynthesis pathways, with further reprogramming of several secondary metabolism pathways such as the phenylpropanoid pathway, flavonoid biosynthesis pathways including flavone and flavanol biosynthesis. Thus, the postulated hypothetical framework, describing biostimulant-induced metabolic events in tomato plants, provides actionable knowledge necessary for industries and farmers to, confidently and innovatively, explore, design, and fully implement Si-based formulations and strategies into agronomic practices for sustainable agriculture and food production.

Food Systems Transformation for Child Health and Well-Being: The Essential Role of Dairy.

Malnutrition, in all its forms, during the critical stages of child growth and development can have lifelong impacts on health and well-being. While most forms of malnutrition can be prevented with simple dietary interventions, both undernutrition and overnutrition remain persistent and burdensome challenges for large portions of the global population, especially for young children who are dependent on others for nourishment. In addition to dietary factors, children’s health also faces the growing challenges of climate change, environmental degradation, pollution, and infectious disease. Food production and consumption practices both sit at the nexus of these issues, and both must be significantly transformed if we are to achieve the 2030 Sustainable Development Goals. Food sources (i.e., animal-source foods vs. plant-source foods), food production practices, the effects of food processing, the impacts of a more globalized food system, and food loss and waste have all been receiving growing attention in health and sustainability research and policy discussions. Much of this work points to recommendations to reduce resource-intensive animal-source foods, heavily processed foods, and foods associated with excessive waste and pollution, while simultaneously increasing plant-source options. However, some of these recommendations require a little more nuance when considered in the context of issues such as global child health. All types of foods can play significant roles in providing essential nutrition for children across the globe, and for improving the well-being and livelihoods of their families and communities. Dairy foods provide a prime example of this need for nuance, as both dairy production practices and consumption patterns vary greatly throughout the world, as do their impacts on child health and food system sustainability. The objective of this narrative review is to highlight the role of dairy in supporting child health in the context of food system sustainability. When considering child health within this context it is recommended to take a holistic approach that considers all four domains of sustainability (health, economics, society, and the environment) to better weigh trade-offs, optimize outcomes, and avoid unintended consequences. To ensure that children have access to nutritious and safe foods within sustainable food systems, special consideration of their needs must be included within the broader food systems transformation narrative.
