Interdisciplinary insights on the future of food systems research: perspectives from the next generation of research leaders

Our dominant food system is a primary driver of worsening human and planetary health. Held in March 2022, the Public Health Association of Australia's Food Futures Conference was an opportunity for people working across the food system to connect and advocate for a comprehensive, intersectoral, whole-of-society food and nutrition policy in Australia to attenuate these issues. Conference themes included food systems for local and global good; ecological nutrition; social mobilisation for planetary and public good; food sovereignty and food equity. Students and young professionals are integral in transforming food systems, yet they are under-represented in the academic workforce, across publishing, scientific societies and conference plenaries. A satellite event was held to platform initiatives from early career researchers (ECR) in areas integral for improving planetary and public good. The research topics discussed in this commentary reflect sub-themes of the conference under investigation by ECR: food systems governance and regulation; local food policies; commercial determinants of health; sustainable healthy diets; and food equity and sovereignty.

Between the farm and the fork: job quality in sustainable food systems

Advocates for structural change in the food system see opportunity in alternative food systems (AFS) to bolster sustainability and equity. Indeed, any alternative to industrial labor practices is assumed to be better. However, little is known about what types of jobs are building AFS or job quality. Failing to understand job quality in AFS risks building a sustainable but exploitative industry. Using a unique and large data set on job openings in AFS, this paper narrows this gap by providing an assessment of labor demand and job quality for AFS in the United States between 2010 and 2019. Job advertisements are matched to 2018 Standard Occupation Codes to characterize work. Wages are compared to living wage standards and median incomes by occupation and local labor market. Considering living wage tests and local labor market competitiveness together, the potential for high job quality in AFS is mixed. Optimistically, higher prices in occupation that are close to consumers and experiencing significant labor demand, like food service and sales, saw more competitive wages. However, these roles frequently failed to offer living wages. Farm work occupations underperformed compared to local labor markets. In addition, uncompetitive senior-level jobs may indicate low-quality career pathways for leadership roles charting paths forward in AFS. These results suggest more institutional action are necessary to enhance labor quality within these spaces and more broadly across the food system. These results also raise questions about who is able to participate in AFS development and whether barriers to participate may replicate equity blind spots.

The COVID-19, Obesity, and Food Insecurity Syndemic

PURPOSE OF REVIEW

To introduce and provide evidence for the new Syndemic of COVID-19, Obesity, and Food Insecurity and propose strategies for mitigating its impact, particularly among vulnerable populations.

RECENT FINDINGS

The COVID-19 pandemic has exacerbated obesity, food insecurity, and the existing inequities in the essential workforce. Food insecurity is driven by unsustainable dietary patterns and is associated with higher rates of obesity, which increases the risk of COVID-19 infections, hospitalizations, and deaths. The COVID-19 pandemic has disproportionately impacted the essential food supply chain workforce. Strengthening the social safety net and expanding worker protections will increase food security and secure livelihoods during and beyond the scope of the COVID-19 pandemic. Strengthening local and regional food systems provides a common solution to both the new Syndemic of COVID-19, Obesity, and Food Insecurity and the Global Syndemic of Obesity, Undernutrition, and Climate Change by promoting sustainable food production and consumption, and prioritizing the food supply chain workforce.

The complex challenge of governing food systems: The case of South African food policy

International experience reveals that food policy development often occurs in silos and offers few tangible mechanisms to address the interlinked, systemic issues underpinning food and nutrition insecurity. This paper investigated what South African government policies cover in terms of different aspects of the food system, who is responsible for them, and how coordinated they are. Policy objectives were categorized into seven policy domains relevant to food systems: agriculture, environment, social protection, health, land, education, economic development, and rural development. Of the ninety-one policies reviewed from 1947-2017, six were identified as being "overarching" with goals across all the domains. About half of the policies focused on agriculture and the environment, reflecting an emphasis on agricultural production. Policies were formulated and implemented in silos. As a result, learning from implementation, and adjusting to improve impact has been limited. Particularly important is that coordination during implementation, across these complex domains, has been partial. In order to achieve its stated food and nutrition outcomes, including Sustainable Development Goal (SDG) 2, South Africa needs to translate its policies into tangible, practical plans and processes guided by effective coordination and alignment. Key recommendations are practically to align policies to a higher-level "food goal", establish better coordination mechanisms, consolidate an effective monitoring and evaluation approach to address data gaps and encourage learning for adaptive implementation. Actively engaging the existing commitments to the SDGs would draw stated international commitments together to meet the constitutional commitment to food rights into an overarching food and nutrition security law.

Who has a beef with reducing red and processed meat consumption? A media framing analysis

OBJECTIVE

Diets high in red and processed meat (RPM) contribute substantially to environmental degradation, greenhouse gas emissions and the global burden of chronic disease. High-profile reports have called for significant global RPM reduction, especially in high-income settings. Despite this, policy attention and political priority for the issue are low.

DESIGN

The study used a theoretically guided framing analysis to identify frames used by various interest groups in relation to reducing RPM in online news media articles published in the months around the release of four high-profile reports by authoritative organisations that included a focus on the impacts of high RPM production and/or consumption.

SETTING

Four major RPM producing and consuming countries - USA, United Kingdom, Australia and New Zealand.

PARTICIPANTS

None.

RESULTS

Hundred and fifty news media articles were included. Articles reported the views of academics, policymakers, industry representatives and the article authors themselves. RPM reduction was remarkably polarising. Industry frequently framed RPM reduction as part of a 'Vegan Agenda' or as advocated by an elite minority. Reducing RPM was also depicted as an infringement on personal choice and traditional values. Many interest groups attempted to discredit the reports by citing a lack of consensus on the evidence, or that only certain forms of farming and processing were harmful. Academics and nutrition experts were more likely to be cited in articles that were aligned with the findings of the reports.

CONCLUSIONS

The polarisation of RPM reduction has led to a binary conflict between pro- and anti-meat reduction actors. This division may diminish the extent to which political leaders will prioritise this in policy agendas. Using nuanced and context-dependent messaging could ensure the narratives around meat are less conflicting and more effective in addressing health and environmental harms associated with RPM.

The role of plant-based alternative foods in sustainable and healthy food systems: Consumption trends in the UK

A global transformation towards sustainable food systems is crucial for delivering on climate change mitigation targets worldwide. In high- and middle-income settings, plant-based meat and dairy alternatives present potential substitutes for animal sourced foods, and a pathway to transition to more sustainable diets. We examined plant-based alternative foods (PBAF) consumption trends in the UK by analysing repeated cross-sectional food consumption data from the National Diet and Nutrition Survey 2008-2019. Dietary data for 15,655 individuals aged 1.5 years and over were analysed to assess aggregate change in intake of PBAF and six other food groups that play a role in transformative dietary change. Characteristics associated with consumption of PBAF were explored using logistic regression, and consumption patterns in high and low meat consumers were explored by examining intake of potential animal product substitute food groups. The proportion of individuals reporting consumption of any PBAFs increased from 6.7% in 2008-2011, to 13.1% in 2017-2019 (p < 0.01). Compared to 2008-2011 PBAF consumption rose by 115% in 2017-2019 (p < 0.01). Females were 46% more likely than males to report consumption of PBAF (p < 0.01). Millennials (age 24-39 years) were the most likely generation to report PBAF consumption (p < 0.01 compared to generation Z (age 11-23 years) and traditionalists (age 75+ years)), as were individuals of the highest income tertile (p < 0.01). Among "low meat consumers", PBAF consumption was on average higher than "high meat consumers" (18.6 g versus 4.8 g PBAF per day, p < 0.01). Our results support the hypothesis of a pivotal role of PBAF in the transition towards sustainable food systems in the UK, by demonstrating they are becoming increasingly popular among UK consumers. This highlights the urgent need to assess in detail the environmental and health impacts of large scale and population-wide consumption of PBAF in comparison to their animal-based equivalents.

AFHVS 2021 Presidential Address: critical praxis and the social imaginary for food systems transformation

In this 2021 AFHVS Presidential Address, Kim Niewolny provides a brief foray into the onto-epistemic framing of critical praxis for sustainable food systems transformation. Niewolny proposes we engage in the creative entanglement of critical praxis and the social imaginary to "unthink" the orthodoxies that govern our ideas of the possible. She offers several possibilities as pathways toward a food system that embodies health equity, ecological justice, land sovereignty, and human rights, including: (1) agroecological research and movement building; (2) food, farm, and health policy; (3) food and farm system worker protections as public health and human rights concerns; (4) intersectional food justice scholarship and curriculum; (5) narrative-led, community-based, and action-oriented methodologies as multi-dimensional inquiry; (6) and multi-sector and multi-racial coalitions as dynamic networks that challenge linear, neoliberal, and technical-rational practices. Niewolny concludes with a call for radical hope as a principle for critical food systems praxis.

Open source software toolchain for automated non-targeted screening for toxins in alternative foods

Previous published methods for non-targeted screening of toxins in alternative foods such as leaf concentrate, agricultural residues or plastic fed to biological consortia are time consuming and expensive and thus present accessibility, as well as, time-constraint issues for scientists from under resourced settings to identify safe alternative foods. The novel methodology presented here, utilizes a completely free and open source software toolchain for automatically screening unknown alternative foods for toxicity using experimental data from ultra-high-pressure liquid chromatography and mass spectrometry. The process uses three distinct tools (mass spectrometry analysis with MZmine 2, formula assignment with MFAssignR, and data filtering with ToxAssign) enabling it to be modular and easily upgradable in the future. MZmine 2 and MFAssignR have been previously described, while ToxAssign was developed here to match the formulas output by formula assignment to potentially toxic compounds in a local table, then look up toxic data on the Open Food Tox Database for the matched compounds. This process is designed to fill the gap between food safety analysis techniques and developing alternative food production techniques to allow for new methods of food production to be preliminarily tested before animal testing. The methodology was validated against a previous method using proprietary commercial software. The new process identifies all of the toxic elements the previous process identified with more detailed information than the previous process was able to provide automatically.•Efficient analysis to find potentially toxic compounds in alternative foods and resilient foods.•Identification of potentially unsafe products without the use of live animal testing.•Modular free and open source design to allow for upgrading or fitting of user needs.

A Sustainability Compass for policy navigation to sustainable food systems

Growing acknowledgement that food systems require transformation, demands comprehensive sustainability assessments that can support decision-making and sustainability governance. To do so, assessment frameworks must be able to make trade-offs and synergies visible and allow for inclusive negotiation on food system outcomes relevant to diverse food system actors. This paper reviews literature and frameworks and builds on stakeholder input to present a Sustainability Compass made up of a comprehensive set of metrics for food system assessments. The Compass defines sustainability scores for four societal goals, underpinned by areas of concern. We demonstrate proof of concept of the operationalization of the approach and its metrics. The Sustainability Compass is able to generate comprehensive food system insights that enables reflexive evaluation and multi-actor negotiation for policy making.

Boundary politics and the social imaginary for sustainable food systems

In this essay, Kim Niewolny, current President of AFHVS, responds to the 2020 AFHVS Presidential Address given by Molly Anderson. Niewolny is encouraged by Anderson's message of moving "beyond the boundaries" by focusing our gaze on the insurmountable un-sustainability of the globalized food system. Anderson recommends three ways forward to address current challenges. Niewolny argues that building solidarity with social justice movements and engendering anti-racist praxis take precedence. This work includes but is not limited to dismantling the predominance of neoliberal-fueled technocratic productivism in agricultural science and policy while firmly centering civil society collective action and human rights frameworks as our guiding imaginary for racial, gender, environmental, and climate justice possibilities for sustainable food systems praxis. She concludes by exploring the epistemic assertion to push beyond our professional and political imaginaries to build a more fair, just, and humanizing food system.

AFHVS 2020 presidential address: pushing beyond the boundaries

In this 2020 AFHVS Presidential Address, Molly Anderson suggests that we must push beyond the boundaries imposed by our training, institutional reward systems, political system and comfort zones in order to solve global challenges. She lists five challenges facing those who are trying to build more sustainable food systems: overcoming the technocratic and productivist approach of industrial agriculture, avoiding future pandemics, restoring degraded and depleted systems and resources, remaining united as a movement while creating collaborations with other movements, and redistributing power across food system actors so that everyone can realize their human rights, including the right to food. She describes three ways that she has found to be effective in pushing beyond boundaries: international collaborations, interactions with global social movements, and anti-racist work. She links these "moments" of opportunity back to the five challenges, and concludes with advice to young scholars.

The power to convene: making sense of the power of food movement organizations in governance processes in the Global North

Dominant food systems, based on industrial methods and corporate control, are in a state of flux. To enable the transition towards more sustainable and just food systems, food movements are claiming new roles in governance. These movements, and the initiatives they spearhead, are associated with a range of labels (e.g., food sovereignty, food justice, and community food security) and use a variety of strategies to enact change. In this paper, we use the concept of relational fields to conduct a post-hoc analysis of nine cases, examining how social movement organizations and other actors actively create new deliberative governance spaces. We argue that successes are related to the "power to convene," a process-oriented approach that increases movements' capacity to mobilize; leverage different types of power; and integrate, coordinate, and build a systems-oriented vision. The power to convene and create deliberative spaces is demonstrated in a variety of contexts and often results in outcomes that further movement aims, including policy change and repositioning food movement actors vis-à-vis others in the field. Our findings suggest that success is not only measured as policy outcomes, but as an advantageous repositioning of social movement actors that enables them to be part of governance processes beyond simple policy advocacy.

The COVID19 pandemic crisis and the relevance of a farm-system-for-nutrition approach

The Covid19 pandemic should be seen as a wake-up call for humanity, to reflect, rethink and redesign food systems that are safe, healthy, sustainable, and beneficial to all. This crisis has disrupted food supply chains, affecting lives and livelihoods. Hunger and malnutrition is expected to increase and the poor and vulnerable will suffer the most. There is urgent need to build resilient food systems. A location specific farm-system-for-nutrition approach, based on sustainable use of natural resources and local agri-food value chains can help improve household diet diversity and address nutrition deficiencies. The food-based approach can improve preparedness and resilience of communities to withstand the challenge posed by crises in general, and COVID19 in particular.

The microbial safety of seaweed as a feed component for black soldier fly (Hermetia illucens) larvae

Farmed insects can offer an environmentally sustainable aquafeed or livestock feed ingredient. The value of black soldier fly (Hermetia illucens) (BSF) larvae could be improved by enrichment in omega-3 through the dietary inclusion of seaweed. However, the industry practice of drying seaweed at low temperatures to retain nutritional properties may benefit the survival of human pathogenic bacteria, particularly if the seaweed has been harvested from contaminated water. Here we have demonstrated that E. coli and E. coli O157:H7 died-off in seaweed dried at 50 °C, although both were detected in the dried powder following 72 h storage. V. parahaemolyticus fell below the level of detection in stored seaweed after drying at ≥ 50 °C, but L. monocytogenes remained detectable, and continued to grow in seaweed dried at ≤60 °C. Therefore, drying seaweed at low temperatures risks pathogen carry-over into insects destined for animal feed. BSF larvae reared on an artificially contaminated seaweed-supplemented diet also became contaminated by all four bacteria present in the supplement. Water quality at seaweed harvesting sites, seaweed desiccation, and insect rearing practices, represent critical points where development of regulatory standards could achieve targeted control of pathogenic hazards.

Exploring Consumers' Purchase Intention of An Innovation of the Agri-Food Industry: A Case of Artificial Meat

Green consumption is an emerging environmental topic receiving global attention. Because livestock production is a primary source of greenhouse gas emission, the "low-carbon diet" has become a new trend in the catering industry. Fast food companies have been launching vegetarian products because artificial meat requires less water and land resources than traditional livestock and has lower carbon emissions. This study explores the influence of consumers' attitude, subjective norms (SNs), and perceived behavioral control (PBC) on their purchase intention for vegetarian burgers from the product knowledge (PK) and environmental concern (EC) perspectives. Based on the theory of planned behavior, the purchase intention of people from different food cultures to pay for fast food burgers is discussed. Five hundred questionnaires were distributed, of which 436 were valid. The results revealed that: (1) consumers' SNs , PBC, and EC significantly affect purchase intention (PI), and SNs and PK have no significant relationship with PI; and (2) vegetarians are willing to pay higher prices than nonvegetarians. This study recommends that industry personnel should attempt to increase consumers' knowledge regarding artificial meat and expand marketing channels to improve the convenience of purchasing artificial meat foods by conducting lectures and media promotion, respectively.

Sustainable food systems, health and infectious diseases: Concerns and opportunities

Food systems have been identified as one of the key issues in the 2030 Agenda for Sustainable Development. Hence, food systems are embodied in the Sustainable Development Goals (SDGs) with a range of ramifications on different goals and targets. Current food systems practices are exposing the vulnerability of populations to various health issues. Indeed, several health challenges, such as malnutrition, infectious diseases, antimicrobial resistance and non-communicable diseases, are caused by existing food systems practices. There is growing awareness of the seriousness of the situation across sectors, including the public health community. The recommended paradigm shift in agriculture and diet are already underway at smaller scales through local efforts. Engaging with food systems towards health, equity, sustainability and resilience is a major opportunity for, as well as responsibility of, the public health community and asks for a training, research, monitoring and advocating role to be played towards policy reform and intersectoral action.

Home-grown school feeding: promoting local production systems diversification through nutrition sensitive agriculture

The consumption of some non-staple crops such as legumes and dark, green leafy vegetables can address common deficiencies in key nutrients such as vitamin A and iron; however, limited markets and supply chain development impede their production and accessibility to consumers. This study investigates the pathways to promote agricultural production and dietary diversity for a local market intervention called Home-Grown School Feeding (HGSF). School feeding menus from 24 districts across 10 regions in Ghana during the 2014–15 school year were analysed in terms of food groups and several individual foods. The menus were then compared with food groups produced by households during the past year or consumed in the past seven days using data collected from a household survey. Greater inter-food group diversity in the menus was associated with higher production levels for tubers and dark, leafy green vegetables in the South and cereals in the North. A correspondence between the frequency in which a food group appeared in a menu and the share of households who consumed foods from the food group was also noted. Key issues, such as optimizing supply chains, enabling farm linkages and supporting diverse nutrient rich food groups, that underlie the success of Home-Grown School Feeding and other agricultural policies with similar goals of promoting production and dietary diversity are highlighted through commodity specific examples. The findings of this study may help strengthen operational linkages between agriculture production and nutrition for HGSF and other similar interventions.

Sustainable food systems-a health perspective

Malnutrition in all forms, ranging from undernourishment to obesity and associated diet-related diseases, is one of the leading causes of death worldwide, while food systems often have major environmental impacts. Rapid global population growth and increases in demands for food and changes in dietary habits create challenges to provide universal access to healthy food without creating negative environmental, economic, and social impacts. This article discusses opportunities for and challenges to sustainable food systems from a human health perspective by making the case for avoiding the transition to unhealthy less sustainable diets (using India as an exemplar), reducing food waste by changing consumer behaviour (with examples from Japan), and using innovations and new technologies to reduce the environmental impact of healthy food production. The article touches upon two of the challenges to achieving healthy sustainable diets for a global population, i.e., reduction on the yield and nutritional quality of crops (in particular vegetables and fruits) due to climate change; and trade-offs between food production and industrial crops. There is an urgent need to develop and implement policies and practices that provide universal access to healthy food choices for a growing world population, whilst reducing the environmental footprint of the global food system.

Sustainable diets within sustainable food systems

Sustainable diets and sustainable food systems are increasingly explored by diverse scientific disciplines. They are also recognised by the international community and called upon to orient action towards the eradication of hunger and malnutrition and the fulfilment of sustainable development goals. The aim of the present paper is to briefly consider some of the links between these two notions in order to facilitate the operationalisation of the concept of sustainable diet. The concept of sustainable diet was defined in 2010 combining two totally different perspectives: a nutrition perspective, focused on individuals, and a global sustainability perspective, in all its dimensions: environmental, economic and social. The nutrition perspective can be easily related to health outcomes. The global sustainability perspective is more difficult to analyse directly. We propose that it be measured as the contribution of a diet to the sustainability of food systems. Such an approach, covering the three dimensions of sustainability, enables identification of interactions and interrelations between food systems and diets. It provides opportunities to find levers of change towards sustainability. Diets are both the results and the drivers of food systems. The drivers of change for those variously involved, consumers and private individuals, are different, and can be triggered by different dimensions (heath, environment, social and cultural). Combining different dimensions and reasons for change can help facilitate the transition to sustainable diets, recognising the food system's specificities. The adoption of sustainable diets can be facilitated and enabled by food systems, and by appropriate policies and incentives.

Med Diet 4.0: the Mediterranean diet with four sustainable benefits

OBJECTIVE

To characterize the multiple dimensions and benefits of the Mediterranean diet as a sustainable diet, in order to revitalize this intangible food heritage at the country level; and to develop a multidimensional framework - the Med Diet 4.0 - in which four sustainability benefits of the Mediterranean diet are presented in parallel: major health and nutrition benefits, low environmental impacts and richness in biodiversity, high sociocultural food values, and positive local economic returns.

DESIGN

A narrative review was applied at the country level to highlight the multiple sustainable benefits of the Mediterranean diet into a single multidimensional framework: the Med Diet 4.0. Setting/subjects We included studies published in English in peer-reviewed journals that contained data on the characterization of sustainable diets and of the Mediterranean diet. The methodological framework approach was finalized through a series of meetings, workshops and conferences where the framework was presented, discussed and ultimately refined.

RESULTS

The Med Diet 4.0 provides a conceptual multidimensional framework to characterize the Mediterranean diet as a sustainable diet model, by applying principles of sustainability to the Mediterranean diet.

CONCLUSIONS

By providing a broader understanding of the many sustainable benefits of the Mediterranean diet, the Med Diet 4.0 can contribute to the revitalization of the Mediterranean diet by improving its current perception not only as a healthy diet but also a sustainable lifestyle model, with country-specific and culturally appropriate variations. It also takes into account the identity and diversity of food cultures and systems, expressed within the notion of the Mediterranean diet, across the Mediterranean region and in other parts of the world. Further multidisciplinary studies are needed for the assessment of the sustainability of the Mediterranean diet to include these new dimensions.

Agroecology and sustainable food systems: Participatory research to improve food security among HIV-affected households in northern Malawi

This article shares results from a long-term participatory agroecological research project in northern Malawi. Drawing upon a political ecology of health conceptual framework, the paper explores whether and how participatory agroecological farming can improve food security and nutrition among HIV-affected households. In-depth interviews were conducted with 27 farmers in HIV-affected households in the area near Ekwendeni Trading Centre in northern Malawi. The results show that participatory agroecological farming has a strong potential to meet the food, dietary, labour and income needs of HIV-affected households, whilst helping them to manage natural resources sustainably. As well, the findings reveal that place-based politics, especially gendered power imbalances, are imperative for understanding the human impacts of the HIV/AIDS epidemic. Overall, the study adds valuable insights into the literature on the human-environment dimensions of health. It demonstrates that the onset of disease can radically transform the social relations governing access to and control over resources (e.g., land, labour, and capital), and that these altered social relations in turn affect sustainable disease management. The conclusion highlights how the promotion of sustainable agroecology could help to partly address the socio-ecological challenges associated with HIV/AIDS.
