Building a more sustainable food system in Colombia: a role for nutrition professionals (2025)

McCullum-Gomez, C., Castillo Quiroga, Y. M., & Diaz-Beltran, M. (2025). Building a more sustainable food system in Colombia: a role for nutrition professionals. Academia Nutrition and Dietetics, 2(2)

This article describes multiple efforts to facilitate the transition to a more sustainable food system in Colombia, which can contribute to the achievement of climate-, biodiversity-, and health-related goals. These interconnected goals are aligned with Colombia’s plan for sustainable development and food sovereignty, guided by a food systems typology developed by the World Wildlife Fund, Colombia, and through support of the concept known as Buen Vivir.

Public health nutrition professionals can increase food security, build food sovereignty, and facilitate the transition to a more sustainable food system in Colombia through: (1) community food gardening and peri-urban and urban agriculture projects; (2) institutional- and consumer-level food waste reduction and prevention programs; and (3) sustainable menu projects that incorporate indigenous, native, and local foods that facilitate the recovery of food memory. Such projects should be participatory and tailored to meet the needs of stakeholders in the different regions of Colombia.

Planet friendly home-grown school feeding: What does it mean? (Africa, 2024 Jul)

Borelli, T., Nekesa, T., Mbelenga, E., Jumbale, M., Morimoto, Y., Bellanca, R., & Jordan, I. (2023). Planet-friendly home-grown school feeding: What does it mean? World Food Programme. https://www.wfp.org/publications/planet-friendly-home-grown-school-feeding-what-does-it-mean

This research seeks to improve the environmental sustainability of school meals in Sub-Saharan Africa by developing a practical tool to guide Planet Friendly procurement practices and HGSF approaches and support the transition to more sustainable food systems.

School meals present a unique opportunity to tackle the various food system challenges, including the depletion and pollution of natural resources, habitat and biodiversity loss, deforestation, ocean acidification, and climate change while delivering multiple social and economic benefits towards sustainable food systems for healthy diets. Despite these advantages, the approach is challenged by the lack of evaluation tools and metrics that can be used to quantify the level of “planet friendliness” in the different regions where the Home Grown School Feeding approach is applied.

Through evaluation of the current school meal supply chain in Sub-Saharan Africa, this study identifies practices in food production, transport, processing, and storage that may influence the impact of school feeding programs on planetary health. The study initially focuses on three main products supplied to schools by the World Food Program (WFP) – maize, beans, and dark green leafy vegetables – and proposes to focus on general agronomic, food processing, and handling practices.

The assessment undertaken has resulted in an evaluation tool for all of WFP’s farmer-directed procurement processes linked to school feeding. The proposed tool, currently in draft form and yet to be tested, provides information about indicators to be included in food procurement policies and processes for the provision of greener school meals in low- and middle-income countries (LMICs). The tool is intended to simplify the evaluation of current procurement processes and guide future decision-making around school procurement to ensure planetary health considerations are widely adopted to bolster systemic resilience. The tool can serve multiple purposes: as a checklist, a scoring template for refining tenders, a monitoring and evaluation tool, or a foundation for co-creating policies for any school feeding program at the school, local, or national level.

What factors influence sustainable and healthy diet consumption? A review and synthesis of literature within the university setting and beyond (2024)

Elliott, P. S., Devine, L. D., Gibney, E. R., & O’Sullivan, A. M. (2024). What factors influence sustainable and healthy diet consumption? A review and synthesis of literature within the university setting and beyond. Nutrition Research, 103, 1-12. https://doi.org/10.1016/j.nutres.2024.03.004

Highlights
• We identified factors that may influence sustainable and healthy diet consumption.
• Using a novel scoring system, these factors were then ranked by priority.
• The scoring system identified high-priority factors to target in future research.
• Most high-priority factors were at the environmental level (e.g., product price).
• These findings can inform the development of future personalized interventions.

Abstract
Globally, typical dietary patterns are neither healthy nor sustainable. Recognizing the key role of dietary change in reducing noncommunicable disease risk and addressing environmental degradation, it is crucial to understand how to shift individuals toward a sustainable and healthy diet (SHD).

In this literature review, we introduced the concept of SHD and outlined the dietary behaviors necessary to transition toward SHD consumption; we reviewed the literature on factors that may influence sustainable (and unsustainable) dietary behaviors in adults; and we developed a novel scoring system to rank factors by priority for targeting in future research. Given the significant potential to promote an SHD transition on the university campus—where factors that may impact dietary behaviors can be targeted at all levels of influence (i.e., individual, interpersonal, environmental, policy)—we narrowed our focus to this setting throughout.

Aided by our novel scoring system, we identified conscious habitual eating, product price, food availability/accessibility, product convenience, self-regulation skills, knowledge of animal ethics/welfare, food promotion, and eating norms as important modifiable factors that may influence university students’ dietary behaviors. When scored without consideration for the university population, these factors were also ranked as the highest priority, as were modified portion sizes.

Our findings offer insight into factors that may warrant attention in future research aimed at promoting SHDs. In particular, the high-priority factors identified from our synthesis of the literature could help guide the development of more personalized dietary behavioral interventions within the university setting and beyond.

Greener Allied Health Professional Hub: Food & Nutrition (NHS, UK)

The UK National Health Service (NHS) has the third largest clinical workforce in the NHS. Allied Health Professionals (AHPs) play an important role in Delivering a Net Zero NHS, which is the overarching framework.

The “Greener Allied Health Professional (AHP) Hub” aims to provide:

Information on the importance of environmental sustainability for both population health and the health of the environment to provide clear actionable steps which AHPs can take to improve their own environmental sustainability.
Examples of the ways in which AHPs are already doing things which improve environmental sustainability to include ‘what good looks like’ for individual AHPs and their teams as well as wider examples demonstrating how AHPs can lead this work in their organisations.
Suggestions of how AHPs can contribute in relation to environmentally sustainable practice, digital, food and diet, use of equipment and public health and prevention.

Food & Nutrition is one of the focus areas for the Greener AHP Hub. As a food and nutrition professional, this NHS resource outlines key areas where you can make a difference in reducing the carbon footprint of healthcare food systems. It highlights your role in reducing food waste through optimizing mealtime support, promoting best practices, and utilizing technology for ordering and monitoring.

By advocating for healthy, low-carbon diets and minimizing packaging waste, you can address the broader impacts of food systems. This resource will help you implement strategies such as conducting waste audits, supporting patients in adopting better eating habits, and promoting the importance of nutrition and hydration among food service staff. Ultimately, this page equips you to link food, health, and climate change initiatives within the NHS, driving sustainable practices and better patient outcomes.

An example is the “Sustainability in Healthcare: Mildmay’s Low-Carbon Menu Transforms Patient Care“. Mildmay Hospital’s dietetics and catering teams, in collaboration with the NHS and dietetics students, developed a low-carbon menu tailored to vulnerable patients using recipes from the NHS England recipe bank. After iterative development and feedback, the winter menu achieved an 18% carbon footprint reduction and minimized food waste to 10% of portions served, while patient input led to further improvements like diverse recipes and a weekly cooked breakfast option for summer.

Drivers of the food system based on food sovereignty domains: an integrative systematic literature review (2024)

Rivera, I., Díaz de León, D., & Pérez-Salazar, M. del R. (2024). Drivers of the food system based on food sovereignty domains: An integrative systematic literature review. Frontiers in Sustainable Food Systems, 8. https://doi.org/10.3389/fsufs.2024.1450321

Abstract

Food sovereignty, as defined by the comprehensive definition offered in the 2007 Nyéléni Forum, encompasses essential action lines for transforming a food system based on food sovereignty principles. Understanding how current food system initiatives align with these principles is essential for identifying the necessary processes of change to drive this transformation. This study aimed to consolidate the contributions of advancements in food sovereignty to the existing literature.

A systematic literature review was conducted to achieve this, analyzing 250 papers published between 2008 and 2023. The focus was on the research methods employed by the authors, food initiatives within the domains of food sovereignty, and the key drivers of a food system rooted in food sovereignty principles.

The findings revealed that approximately 36% of the studies utilized interviews, surveys, and questionnaires for data collection, while 34% concentrated on targeted fieldwork through case studies. Around 19% of the studies involved in-depth interaction with specific groups, and just under 10% employed document analysis methods. The most extensively discussed domain was the use of agroecological management practices for food production, followed by the valuation of traditional knowledge, the promotion of social justice and equity, self-determination through the transformation of economic and political institutions, and the localization of food production and consumption.

The food initiatives outlined overarching goals within each domain of food sovereignty, with three common goals identified across these domains: food security and consumption, environmental stewardship, and crisis preparedness. Furthermore, 29 drivers of a food system based on the domains of food sovereignty were identified, encompassing networks and a holistic approach present in all 5 domains. The study also highlights the implications for supporters of food sovereignty within the context of the identified goals of the food initiatives.

Values-based food systems: the role of local food partnerships in England (2024)

Jackson, P., Yap, C., Parsons, K. et al. Values-based food systems: the role of local food partnerships in England. Agric Hum Values (2024). https://doi.org/10.1007/s10460-024-10670-4 (open access)

Abstract

This paper outlines the concept of values-based food systems building on the related idea of values-based food chains (VBFCs), terms which are definitionally diffuse, but which cohere around a common commitment to environmental sustainability and social justice. The paper examines the development of four multi-stakeholder local food partnerships in Birmingham, Bristol, Rotherham, and Sheffield—and the national Sustainable Food Places network to which they are affiliated.

Based on our collaborative research with these organizations and a review of their public statements, the paper identifies the values that guide their work. The paper then draws on the evidence of a series of workshops, which revealed some of the challenges the partnerships face as they seek to put their values into practice, focusing on governance issues (and related funding challenges) and the implementation of equity, diversity, and inclusion policies.

Our findings show that the partnerships’ work is consistent with the concept of values-based food systems though they do not use the term themselves. Our research also shows the range of work being undertaken by these local food partnerships with much in common but also some significant divergence in their activities. The paper concludes with some reflections about scale and the differences between our English case studies and earlier work on VBFCs in the US.

Abstract:

A transition towards a sustainable and healthy diet (SHD) is crucial for both population and planetary health. However, changing consumer’s behaviour is challenging due to the many factors influencing food choices. Tools that comprehensively assess these factors are paramount, yet none are available in Spain. Hence, we created and validated the SALSA questionnaire to capture self-perceived barriers and facilitators for SHD.

The process involved three phases:
— First, item development combining insights from a scoping review and content validity with experts (n = 9) and the target population (n = 38);
— Second, scale development by pre-testing the questionnaire (n = 4), administering it through an online survey to two samples(Dimensionality-Sample, n = 516; Reliability-Sample, n = 61), and applying exploratory factor analysis for factors extraction and item reduction;
— Third, scale evaluation by testing its dimensionality through confirmatory factor analysis, its reliability through Cronbach’s alpha and McDonald’s omega, and intra-class correlation coefficient, and construct validity through discriminant validity, convergent validity, and correlation analysis.

Results yielded a questionnaire with 27 items grouped into four dimensions: personal factors, sociocultural factors, external factors, and meat and plant-based meat alternatives. The psychometric analysis revealed that the SALSA questionnaire is a reliable instrument to identify behavioural determinants.

The Nyéléni Global Forum (2025)

The world is in unprecedented turmoil, and we are all facing deep-rooted overlapping crises. We need a paradigm shift to reclaim the right to shape our own food systems for the well-being of people and the planet.

Launched in 1996 at the World Food Summit, food sovereignty promotes a people-focused approach to food systems, prioritizing locally produced, stable, healthy, and affordable food over dependence on global markets and neoliberal policies.

The International Nyéléni Forum in Mali (2007) established this vision as a global standard, uniting movements and organizations dedicated to food sovereignty and social justice. In 2015, the Nyéléni International Forum on Agroecology reinforced this, placing peasant, indigenous, family agroecology at the centre of a strategy for addressing climate and biodiversity crises.

That is why the Nyéléni Global Forum are calling for a new mobilization within and beyond the food sovereignty movement, to build our response at both global and local levels, and tighten alliances with climate justice, antiracism, health, labour, feminist, and social and solidarity economy movements and organisations. Through a multi-year process, they’ve brought together thousands of grassroots organizations and other allies across six world regions, to discuss and put forward joint proposals for a system change and a strong political agenda for the years to come.

The Nyéléni Global Forum, to be held in 2025 in India, will be the space for strategy and organization, and to kick off this new phase of the food sovereignty movement.

Open Food Network (website)

The Open Food Network (OFN) is a global network of people and organisations working together to build a new food system. OFN believes a sustainable and resilient food system needs to reconnect producers and consumers.

Together OFN members develop open and shared resources, knowledge, and software to support a better food system. They aim to empower people and communities and give them the tools and knowledge to develop the food systems they need to build new food systems for their community.

OFN has many case studies on their website. They highlight some of the over 847 amazing food enterprises selling on their platform. The case studies go deeper to know more about them – their stories, how they do things, what they care about, and how they make localised food systems happen in their communities.

School Meals Coalition. (2021 website)

The School Meals Coalition is a prominent and innovative vehicle for multilateral action and addresses multiple Sustainable Development Goal (SDG) outcomes. The School Meals Coalition is a government-led and partner-supported effort that aims at ensuring that by 2030 every child worldwide can receive a healthy meal in school. Led by Brazil, Finland, and France, the Coalition was one of the most impactful and successful initiatives coming out of the UN Food Systems Summit in 2021.

The Coalition is an example of a new generation of multilateralism; It’s about governments and partners agreeing to join forces and work together to improve the quality, sustainability, and scale of national school meals programmes and complementary interventions. It is about breaking silos and pooling resources – best practices, experience, information, and technical support. Through its multisectoral and holistic approach, the Coalition addresses implementation bottlenecks, strengthens evidence for decision-making, provides opportunities for improved coordination and generates the political will and buy-in needed for change through advocacy.

Besides food provision (SDG 2), school meal programs boost agriculture, create jobs, increase school attendance and learning, and enhance health. They function as in-kind cash transfers, promoting social stability, gender equity, and comprehensive social protection efforts. Additionally, school meals programmes can integrate complementary interventions, including WASH (Water, Sanitation, and Hygiene), nutrition education, and other routine school health and nutrition services.

School meals represent a powerful, multisectoral tool, which can contribute to achieving multiple Sustainable Development Goals, including poverty (SDG1), hunger (SDG2), health (SDG3), education (SDG4), gender equality (SDG5), economic growth (SDG8), reduced inequalities (SDG10), Responsible consumption and production (SDG12), climate action (SDG13) and strengthened partnerships (SDG17).

To achieve this member states have set three objectives:

Restore all national school meal programmes lost to the pandemic by 2023
Reach the 73 million most vulnerable children who were not reached even prior to the pandemic by 2030
Improve the quality and efficiency of school health and nutrition programmes globally by 2030
