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.

Physicians Association for Nutrition (PAN)(website)

The Physicians Association for Nutrition (PAN) is an international NGO on a mission to eliminate diet-related deaths globally. By making nutrition a core part of healthcare and by engaging health professionals in efforts towards healthy and sustainable food environments they are advancing the food transformation needed to mitigate the three largest global health crises: chronic disease, climate change, and pandemic risk.

One in 5 premature deaths globally is due to poor nutrition. The current food system is also fuelling the climate crisis and pandemic risk. At the same time, physicians tend not to use the immense power of nutrition to prevent and treat disease in the first place. Their mission is to address this issue at the source and educate medical students and physicians about how nutrition can be used as an effective tool to treat their patients. Through empowering healthcare professionals with the tools, techniques and know-how to treat their patients differently, PAN enables them to save more lives. The PAN Academy has an online learning platform that makes nutrition education accessible to everyone.

PAN also approaches the bigger global problems of the broken food system by engaging an international community and support network of physicians, dietitians, medical students, and other healthcare workers. Through combined efforts, they can influence policy-makers and change food environments for the good of human and planetary health.

PAN’s influence is expanding and they regularly establish new national branches around the world. By partnering with like-minded international colleagues they can work effectively at a local, national and international scale to maximise impact. They have established branches in various countries in Europe and beyond, and they continue to grow their reach globally. Their national branches are all registered non-profit organisations in their respective countries.

In 2018 PAN signed a joint open letter on the need for a strong proposal on an EU legislative framework for sustainable food systems.

By empowering healthcare professionals with the tools‭, ‬techniques‭, ‬and knowledge to treat their patients differently‭, ‬PAN empowers‭ ‬them to enhance patient care and save lives around the world‭, ‬while also protecting our planet and global resources‭.‬

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:

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

Planet-friendly school meals: opportunities to improve children’s health and leverage change in food systems (2024)

Pastorino, S., et al. (2024, November 18). Planet-friendly school meals: Opportunities to improve children’s health and leverage change in food systems. The Lancet Planetary Healthhttps://doi.org/10.1016/S2542-5196(24)00302-4

Planet-friendly school meals, defined as programmes delivering equitable and healthy foods for children, produced in ways that do not pollute or overexploit natural resources and protect biodiversity, are a platform to tackle many food system challenges.

Multiple stakeholder collaborations are required to move towards planet-friendly school meals. This entails changes directed at two sets of policies as outlined in the Planet-friendly school meals conceptual framework (figure): those making immediate changes to school meal programmes; and those developing demand-driven planet-friendly procurement policies that promote ecological farming and develop sustainable regional food systems.

School meals, mostly state-funded, reach 418 million children every day worldwide offering an opportunity to improve diet quality, and ultimately nutrition and health, and act as a catalyst for food systems transformation contributing to meeting global climate, food, and biodiversity goals.

Good Practices in School Gardens and School Meals: Africa, Asia and Latin America and the Caribbean (2024)

As part of food and nutrition education actions and a component of Sustainable Schools, the Programme encourages school garden initiatives, considering their potential to transform food habits of current and future generations, training students to be aware of the impacts of food production on the environment and on agri-food systems. In addition, with the greater impact of climate change, this educational tool becomes even more relevant as it can offer concrete contributions to the mitigation of climate effects.

Since 2009, the Brazil-FAO International Cooperation Programme for School Meals, an alliance between the National Fund for Education Development (FNDE), the Brazilian Cooperation Agency (ABC) and the United Nations Food and Agriculture Organisation (FAO), has been developing activities to strengthen and institutionalise school meal programmes in Latin America and the Caribbean (LAC).

About 2 billion people in the world are overweight or obese due to a poor diet and sedentary lifestyle. Around 133.4 million Latin Americans and Caribbeans do not have access to a healthy diet. In addition, this region has the highest healthy food costs (LAC Food and Nutrition Security Overview, 2023).

Given this scenario, the cooperation has promoted actions aimed at offering healthy and adequate menus, public procurement from smallholder farming, improvement of school infrastructure and food and nutrition education actions such as school gardens, exchanges of experiences, training and technical visits between 26 LAC countries, within the framework of the Sustainable School Feeding Network (RAES).

Global Roots (website)

Global Roots promotes regenerative, equitable, and nutritious plant-based food systems by modeling agricultural conservation projects, partnering with organizations around the world to implement whole systems change, and providing on-the-ground education programs. They are based in the USA* and the Dominican Republic** in partnership with the T. Colin Campbell Center for Nutrition Studies and are exploring other expansion areas. By recognizing the overlap between nutrition for personal and planetary health, we can drastically improve global health standards while simultaneously reducing agricultural land use requirements paving the way for increased conservation.

Objectives:

  • Expand the practice of agriculture as a form of conservation, life-enhancement, and regeneration to areas around the world.
  • Provide education opportunities on how to transition consolidated, top-down food systems to community-owned land trusts and regenerative land practices.
  • Demonstrate through model programs how transitioning inefficiently used farmland from speculative markets to locally-owned land initiatives increases healthy food options, employment opportunities, and resilient communities of health.
  • Increase peer-to-peer networking and coalition building through the Whole-Communities platform.
  • Provide technical support to promote regenerative, equitable, and nutritious plant-based food systems.

* The Brightside Farm and Nursery in the USA is the home of Global Roots. The farm is located outside of Chapel Hill, North Carolina in growing zone 8a and covers an area of 2.5 acres hosting the nursery, mixed vegetable production, and orchard. Operations of the farm and nursery are governed by the Global Roots staff and board of directors.

** The RAICES Institute education center is located in the Dominican Republic in the province of Las Hermanas Mirabal, north of Salcedo in the village of La Cumbre. The center is owned and operated by RAICES Global with program support from Global Roots and the T. Colin Campbell center for Nutrition Studies. The center hosts education programs and aims to establish plant-based communal food hubs.

Options for reforming agricultural subsidies from health, climate, and economic perspectives (2022)

Springmann, M., Freund, F. Options for reforming agricultural subsidies from health, climate, and economic perspectives. Nat Commun 13, 82 (2022). https://doi.org/10.1038/s41467-021-27645-2

Agricultural subsidies are an important factor for influencing food production and therefore part of a food system that is seen as neither healthy nor sustainable. Here we analyse options for reforming agricultural subsidies in line with health and climate-change objectives on one side, and economic objectives on the other.

Using an integrated modelling framework including economic, environmental, and health assessments, we find that on a global scale several reform options could lead to reductions in greenhouse gas emissions and improvements in population health without reductions in economic welfare. Those include a repurposing of up to half of agricultural subsidies to support the production of foods with beneficial health and environmental characteristics, including fruits, vegetables, and other horticultural products, and combining such repurposing with a more equal distribution of subsidy payments globally.

The findings suggest that reforming agricultural subsidy schemes based on health and climate-change objectives can be economically feasible and contribute to transitions towards healthy and sustainable food systems.
