Unhealthy dietary patterns drive $8 trillion in annual hidden costs of global agrifood systems

A refined study by the Food and Agriculture Organization of the United Nations (FAO), involving 156 countries confirms that hidden costs within global agrifood systems amount to approximately $12 trillion annually. Of this figure, around 70 percent ($8.1 trillion) arise from unhealthy dietary patterns and are linked to alarming non-communicable diseases (NCDs), such as heart disease, stroke, and diabetes, far exceeding the costs related to environmental degradation and social inequalities
The State of Food and Agriculture 2024 (SOFA), builds on the 2023 edition to provide an even more in-depth analysis, utilising true cost accounting to expose the full range of costs and benefits associated with food production, distribution, and consumption, including those that are not reflected in market prices – the so-called “hidden costs and benefits”. The report updates those cost estimates, divides them by agrifood system types, and charts a course for transformative change in the agrifood systems.
The study details how global hidden costs are largely driven by health hidden costs, followed by environmental hidden costs, in more industrialised agrifood systems in upper-middle- and high-income countries.
In examining health impacts, the report identifies 13 dietary risk factors. These include insufficient intake of whole grains, fruits, and vegetables; excessive sodium consumption; and high intake of red and processed meats, with notable differences across various agrifood systems.
Hidden costs vary depending on the type of agrifood systems
Historically, agrifood systems have transitioned from traditional to industrial, each with varied outcomes and hidden costs. For this reason, the report explores how hidden costs manifest themselves in different agrifood system types worldwide.
To facilitate analysis, the research introduces a typology that categorises agrifood systems into six distinct groups: protracted crisis, traditional, expanding, diversifying, formalising, and industrial. This framework allows for a targeted understanding of the unique challenges and opportunities inherent to each system, enabling the development of tailored policies and interventions.
For instance, while diets low in whole grains are the leading dietary risk factor across most agrifood systems, in protracted crisis systems (those experiencing prolonged conflict, instability, and widespread food insecurity) and traditional systems (characterised by lower productivity, limited technology adoption, and shorter value chains), the primary concern is a low intake of fruits and vegetables.
High sodium intake is another significant concern, exhibiting an upward trend as agrifood systems evolve from traditional to formalising, peaking in the latter and then decreasing in industrial systems. Conversely, high consumption of processed and red meat steadily increases throughout the transition from traditional to industrial systems, where it ranks among the top three dietary risks.
Beyond dietary risks, the environmental impact of unsustainable agricultural practices contributes substantially to the hidden cost burden. Costs associated with greenhouse gas emissions, nitrogen runoff, land-use changes, and water pollution are particularly high in countries with diversifying agrifood systems – where rapid economic growth is coupled with evolving consumption and production patterns – reaching an estimated $720 billion. Formalising and industrial agrifood systems also face significant environmental costs. However, countries facing protracted crises bear the highest relative environmental costs, equivalent to 20 percent of their GDP.
Social costs, including poverty and undernourishment, are most prevalent in traditional agrifood systems and those affected by protracted crises. These social costs represent 8 and 18 percent of GDP, respectively, highlighting the urgent need for improved livelihoods and integrated humanitarian, development, and peacebuilding efforts.
SOFA 2024 underscores the importance of adapting to local contexts and capturing stakeholder priorities. This is illustrated through case studies representing diverse countries and agrifood system types, including Australia, Brazil, Colombia, Ethiopia, India, and the United Kingdom.
A call for collective action
Overall, the report calls for a value-driven transformation of agrifood systems to make them more sustainable, resilient, inclusive, and efficient. This requires going beyond traditional economic measures like GDP by utilising true cost accounting to recognise hidden costs. With this approach, decision-makers can make more informed choices that enhance the societal value of agrifood systems, acknowledging their essential roles in food security, nutrition, biodiversity conservation, and cultural identity. Achieving this transformation also demands bridging sectoral divides, aligning policies across health, agriculture, and the environment, and ensuring that the benefits and costs are equitably shared among all stakeholders.
QU Dongyu, FAO Director-General, said, “The choices we make now, the priorities we set and the solutions we implement will determine our shared future. Real change begins with individual actions and initiatives, supported by enabling policies and targeted investments. The transformation of global agrifood systems is fundamental to achieving the SDGs and securing a prosperous future for all.”
