Studies and Reports of the Month: January 2026

January featured eight significant, peer-reviewed studies and two non-academic reports from a range of fields – spanning agricultural economics, fiscal policy, behavioral science, food governance, nutrition science, and supply chain analysis – that cover an increasingly common thread: the rising costs and risks of animal agriculture and the need for more modeling on plant -forward alternatives as structural solutions.

Contents

Studies:

  1. Stranded Assets in European Agriculture During Food System Transformations
    • Nature Food
    • The first study to translate dietary transition resistance into concrete financial figures: €61 – 255 billion in EU agricultural assets are at risk depending on the pace of transition towards more plant -forward diets.
  2. Environmental Impacts from European Food Consumption Can Be Reduced with Carbon Pricing or VAT Reform
    • Nature Food
    • Removing VAT subsidies on meat products could cut EU food-system environmental impacts by 3.5-5.7% immediately, at a net cost of just €5- 12 per person per year.
  3. Food Supply and Dietary Guidelines Mismatch: Policy Recommendations
    • Health Affairs
    • Zero of twelve countries studied provide adequate vegetables, legumes, or nuts, while nine oversupply meat, eggs, and sugar.
  4. Not All Ultra-Processed Foods Are Created Equal: A Review
    • BMJ Nutrition, Prevention & Health
    • Ultra-processed food (UPF) health risks concentrate in animal-based products, with 54- 125% increased disease risk, while plant -based UPFs show the opposite patterns with a 54% decreased diabetes risk.
  5. How Has the Global Food Governance System Evolved?
    • Globalization and Health
    • Food governance fragmentation is not an accidental coordination failure but a deliberate structural outcome – powerful actors secured binding trade protections while keeping food sustainability governance voluntary and under-resourced.
  6. Dynamic Social Norm Messages Increase Plant -Based Food Choice
    • Food Quality and Preference
    • Messages emphasizing changing trends in plant -based eating increased selection by up to 20%, while traditional descriptive norms showing current majority behavior had no effect.
  7. Small Farms Contribute a Third of Food Consumed in High-Income Nations
    • Nature Food
    • When trade flows are accounted for, small-scale farms contribute approximately one-third of all food consumed in high-income OECD nations – substantially more than domestic production.
  8. Evidence from Randomized Trials on Lipid-Lowering by Culinary Herbs and Spices
    • Academia Nutrition and Dietetics
    • Five common herbs and spices demonstrate cholesterol reductions – across 55 meta-analyses of RCTs – comparable to dietary fiber interventions.

Reports

  1. The Meat of the Matter: What Does Declining UK Meat Consumption Mean for Livestock Farmers?”
    • Green Alliance
    • UK grazing livestock farms lose money on meat production and survive on subsidies alone, with average incomes rising ~50% if the same land shifts to carbon sequestration and nature restoration. The 2027 subsidy phase-out creates a concrete policy window.
  2. “The $540B Grocery Bill: Unlocking the Hidden Value of Food Waste”
    • Avery Dennison
    • Meat represents 50% of retail food waste opportunities globally, producing 1.7- 2.5x more methane than plant waste in landfill, yet the industry’s $540 billion waste reduction strategy treats dietary composition as fixed rather than as an intervention.

Studies

1. Stranded Assets in European Agriculture During Food System Transformations

Kortleve, A.J., Mogollón, J.M., Harwatt, H. et al. Nature Food 7, 38-44 (2026). DOI: 10.1038/s43016-025-01283-z

KEY TAKEAWAY: The first study to quantify the financial exposure of EU agriculture to dietary transitions – €61 – 255 billion in assets at risk – creating new frameworks for just transition policy and financial sector risk assessment.

About

This groundbreaking study analyzes comprehensive farm accounting data across 3.7 million EU farms, combined with global input -output models, to estimate the value of agricultural assets that could become stranded under dietary transition scenarios. It models multiple transition speeds and dietary shift pathways, producing the first concrete financial estimates of what “resistance to dietary change” actually costs in asset terms.

Key evidence
  • €61- 255 billion in EU agricultural assets are at risk depending on dietary transition pace. This is the first translation of abstract dietary transition risk into concrete financial figures – a category of analysis that did not previously exist.
  • The EU’s Common Agricultural Policy ( CAP) spends €51 billion annually in subsidies that could fund an orderly 10-30 year transition if redirected from supporting current production patterns toward transformation.
  • Feed crop production accounts for ~40% of stranded asset risk, identifying an overlooked stakeholder group – arable farmers growing feed – who are also financially exposed to dietary transitions.

Implications for food systems transformation

This study fundamentally changes how financial institutions can assess agricultural transition risk. Pension funds manage roughly US $55-60 trillion in assets globally – over one in three institutional investment dollars – yet most have no framework for evaluating agricultural stranded asset exposure.

It also reframes farmer resistance to dietary change not as cultural stubbornness, but as rational economic behavior, which opens different and more productive policy conversations about managing transition. The finding that CAP subsidies alone could finance an orderly transition provides a concrete fiscal mechanism for policymakers.

Who should care? Pension fund managers and institutional investors assessing portfolio exposure to agricultural transition risk. CAP reform policymakers. Just transition advocates seeking to build coalitions that include feed crop farmers alongside livestock producers.

Gaps and next steps

The study models EU agricultural systems and may not directly generalize to other major producing regions with different subsidy structures ( e.g., the US, Brazil, India). The analysis focuses on financial exposure without modeling the employment and community-level impacts of asset stranding. Future work should examine how these financial risks interact with existing pension fund portfolios and whether disclosure frameworks (analogous to climate-related financial disclosures) could accelerate institutional response.

2. Environmental Impacts from European Food Consumption Can Be Reduced with Carbon Pricing or VAT Reform

Plinke, C., Sureth, M. & Kalkuhl, M. Nature Food 7, 74-87 (2026). DOI: 10.1038/s43016-025-01284-y

KEY TAKEAWAY: Removing VAT subsidies on meat products would reduce EU food-system environmental impacts by 3.5-5.7% at negligible net household cost (€5- 12 per person per year) when revenues are redistributed – providing a concrete, immediately deployable policy lever.

About

This modeling study analyzes two fiscal mechanisms – VAT reform and emission pricing – across all 27 EU member states, using country-specific demand systems and comprehensive environmental footprinting across six indicators: greenhouse gas emissions, land use, water use, biodiversity loss, nitrogen pollution, and phosphorus pollution. It specifically examines the impact of removing existing VAT reductions on meat products.

Key evidence
  • Removing the effective meat subsidy increased the average price of meat products by 10.6%, reducing meat demand by 8- 11.3% on average across EU countries. This alone drove dietary environmental impacts down by 3.5-5.7%.
  • Broader emission pricing at €52/tCO₂e across all foods achieved 5-8% reductions long-term. EU food consumption generates 23% of household GHG emissions but 55- 71% of land, biodiversity, nitrogen, and water impacts – making meat and dairy taxation especially powerful for multi-dimensional environmental benefits.
  • Net household costs are trivial when revenues are redistributed: €5- 12 per person per year, with revenue-neutral design converting a regressive instrument into a progressive one.
Implications for food systems transformation

The study offers a clear policy sequencing roadmap: meat VAT reform now, as immediate low-hanging fruit, followed by comprehensive emission pricing from 2031. It demonstrates that even modest price corrections produce outsized environmental returns.

Crucially, the research comprehensively documents animal agriculture’s environmental costs across six indicators and 27 countries – but does not model plant -forward dietary transitions as the structural solution that these fiscal interventions enable.

Gaps and next steps

The demand modeling relies on historical price elasticities, which may underestimate long-term behavioral responses as social norms shift. The study does not model cross-border effects (trade diversion) or the interaction between fiscal policy and supply-side reforms ( e.g., CAP changes). Real-world implementation would require navigating EU fiscal sovereignty constraints and agricultural lobby opposition.

3. Food Supply and Dietary Guidelines Mismatch: Policy Recommendations to Improve Human and Planetary Health

Fischer, I., Narayan, K. M., & Siegel, K. Health Affairs 44:4, 467-474 (2025). DOI: 10.1377 /hlthaff.2024.0133

KEY TAKEAWAY: No country studied provides adequate vegetables, legumes, or nuts. Nine of twelve oversupply meat, eggs, and sugar. Animal agriculture uses 84% of land to produce 17% of calories -demonstrating systemic production-health misalignment.

About

The study compares FAO food supply data (2016- 20 averages) against the EAT -Lancet planetary health diet benchmarks across twelve strategically selected countries representing 52% of the global population and diverse income levels. It examines supply adequacy across major food groups and identifies policy levers to close the gap.

Key evidence
  • Zero of twelve countries analyzed provide sufficient vegetables, legumes, or nuts relative to planetary health diet benchmarks, while nine oversupply animal products and sugar.
  • Animal agriculture uses 84% of global agricultural land to produce just 17% of calories – a resource efficiency ratio that speaks to the systemic misalignment between production patterns and nutritional needs.
  • The study identifies a Finland precedent: a deliberate dairy-to-berry production shift contributed to a 73% reduction in cardiovascular mortality – demonstrating that supply-side realignment can deliver measurable health outcomes.
Implications for food systems transformation

This research provides defensible, high-confidence statistics for public communications on supply-demand mismatch. The four proven policy levers identified – subsidy reform, crop insurance redesign, R&D redirection, and tariff adjustment – offer a concrete reform agenda. Theland-use efficiency data enables coalition-building between climate advocates focused on land efficiency and public health advocates focused on chronic disease prevention, connecting these constituencies around shared solutions.

Gaps and next steps

The study relies on national-level supply data rather than actual consumption data, which may overstate availability (supply includes waste). Country-level averages may obscure significant sub-national variation. The Finland case study, while compelling, involved a multi-decade effort whose specific policy architecture may not be directly replicable.

4. Not All Ultra-Processed Foods Are Created Equal: A Review

Kahleova H., Himmelfarb J., Barnard N. BMJ Nutrition, Prevention & Health (2026) https://doi.org/10.1136/bmjnph- 2025-001358

KEY TAKEAWAY: Ultra-processed food (UPF) health risks concentrate in animal-based products, with processed meats increasing diabetes risk by 54%, colorectal cancer mortality by 125%, and cardiovascular disease by 51%. Plant -based ultra-processed foods show the opposite pattern: a 54% decreased diabetes risk despite equivalent classification within the NOVA system.

About

Systematic review (narrative synthesis) of 14 studies – 12 prospective cohorts with 7,774 to 311,892 participants and 2 randomized controlled trials – examining whether the NOVA ultra-processed food classification masks important differences between animal-based and plant -based products. Covers cohorts from the US, Europe, Brazil, South Korea, Greece, and Mexico.

Key evidence
  • Animal-based UPFs consistently harmful: Processed meats increased type 2 diabetes risk by 54%, colorectal cancer mortality by 125%, and cardiovascular disease risk by 51% across multiple large cohort studies with long follow-up periods.
  • Plant -based UPFs consistently protective: Ultra-processed plant -based alternatives, whole grain breads, and cereals were associated with 54% decreased type 2 diabetes risk – the inverse of animal-based UPF effects despite equivalent processing levels under NOVA classification.
  • RCT evidence supports causal interpretation: Two randomized controlled trials demonstrated that replacing animal products with plant -based foods, regardless of processing level, produced significant weight loss (mean 6.2 kg) and metabolic improvements.
  • Sweetened beverages are a separate harmful category regardless of source, with 22% increased diabetes risk – the one UPF subgroup where the animal/plant distinction does not apply.
Implications for food systems transformation

This review provides the scientific foundation for differential regulatory treatment of ultra-processed foods by source ingredient. Meat and dairy taxation, procurement restrictions, and front -of-package labeling need not extend to plant -based alternatives or whole grain products. It directly counters a key industry objection: the claim that plant -based alternatives are “ultra-processed too” rests on a generalization within the NOVA system. For institutional food environments, school meal standards, hospital food procurement, and food service guidelines can now distinguish animal-source from plant -source ultra-processed foods without abandoning the broader UPF health framework.

Gaps and next steps

The study is a narrative synthesis rather than a quantitative meta-analysis, and the search was limited to PubMed ( excluding Embase, Web of Science, and other databases). No formal quality assessment tool was applied to included studies, and observational cohorts remain subject to residual confounding. The authors’ PCRM affiliation is transparently disclosed but warrants pairing with independent sources for external citation. No dose-response analysis was conducted across studies. The most valuable next step would be a formal meta-analysis with quantitative pooling of animal-based vs. plant -based UPF effects, ideally conducted by an independent research team.

5. How Has the Global Food Governance System Evolved, and What Challenges Does It Currently Pose for Food Systems Transformation?

Slater, S., Lawrence, M., Wood, B. et al. Global Health 22, 17 (2026). DOI: 10.1186/s12992-025-01172- x

KEY TAKEAWAY: Food governance fragmentation is not accidental but structurally engineered: powerful actors created binding trade and IP protections (WTO ) while ensuring food security, sustainability, and dietary transition governance remained voluntary, under -resourced, and unable to challenge corporate concentration.

About

This study synthesizes 114 publications examining the institutional evolution of global food governance from the 1940s to the present, using a political economy framework. It traces how the current governance architecture emerged, identifies whose interests it serves, and explains why topics like corporate concentration and plant -forward dietary transitions have been systematically excluded from mainstream governance forums.

Key evidence
  • The study documents a deliberate asymmetry in global food governance: binding international rules protect commercial interests (trade, intellectual property), while governance of food security, sustainability, and public health remains voluntary, fragmented, and chronically under-resourced.
  • Specific topics have been systematically excluded from mainstream governance forums: corporate concentration in food systems, alternatives to industrial agriculture, and plant -forward dietary transitions.
Implications for food systems transformation

This work reframes the advocacy challenge from “better coordination among existing institutions” to “democratizing governance structures that were designed to exclude these topics.” It identifies actionable entry points: the trade-environment nexus, agricultural subsidy reform through WTO mechanisms, and right -to-food litigation. It also identifies coalition-building opportunities with labor, agroecology, and anti-monopoly movements that face the same structural exclusion.

Gaps and next steps

As a synthesis paper, it organizes existing knowledge rather than generating new empirical data. The political economy framework is interpretive rather than predictive – it explains why governance looks the way it does but does not offer a roadmap for changing it. The actionable pathways (trade-environment nexus, right -to-food litigation) are identified but not evaluated for feasibility or likely impact.

6. Exposure to Dynamic Social Norm Messages Increases Plant -Based Food Choice: An Online and Field-Based Experiment

Edwards, K., et al. Food Quality and Preference, 139 (2026) DOI: 10.1016/j.foodqual.2026.105856

KEY TAKEAWAY: Messages emphasizing changing trends in plant -based eating (“more people are choosing plant -based”) increased selection by 7- 20%, while traditional descriptive norms showing current majority behavior had no effect – challenging conventional wisdom about social influence on dietary choice.

About

The study uses a dual-method design: an online experiment (n=892 across 8 countries) validated by a field study in 45 German quick -service restaurants tracking ~ 135,000 actual purchases. It tests whether dynamic social norms ( emphasizing changing trends) outperform traditional descriptive social norms ( describing current majority behavior) in influencing plant -based food selection.

Key evidence
  • Dynamic norm messages (up to a 20% increase in plant -based selection) significantly outperformed descriptive norm messages (no effect). This suggests that emphasizing direction of change matters more than describing current behavior.
  • The field validation across 135,000 real purchases in 45 restaurants provides strong ecological validity – it translates to actual purchasing behavior in real restaurant environments.
Implications for food systems transformation

The critical insight is that message framing matters enormously: communicating “more people are choosing plant -based” is effective while “most people choose meat” is not, even though both are factually accurate. This insight has direct applications for institutional food service, digital menu design, and public communications. This work offers an immediately deployable, low-cost intervention for quick -service restaurant digital ordering platforms.

Gaps and next steps

Long-term effects remain unknown – do people habituate to dynamic norm messages? – and the study does not examine interactions with other interventions (pricing, defaults, availability). The 7- 20% range is wide and context -dependent; understanding which conditions drive the upper versus lower end of that range would improve deployment decisions. Prior research on choice architecture shows approximately 30% backfire rates, suggesting continued caution about over-reliance on behavioral nudges.

7. Small Farms Contribute a Third of the Food Consumed in High-Income Nations

Taherzadeh, O., Cai, H. & Mogollón, J.M. Nature Food 7, 66- 73 (2026). DOI: 10.1038/s43016-025-01276-y

KEY TAKEAWAY: When trade flows are accounted for, small-scale farms (≤20 hectares) contribute approximately one-third of all food consumed in high-income OECD nations – a substantially larger role than domestic production statistics suggest.

About

The study integrates trade flow data with farm-size production statistics to estimate the contribution of small-scale farms to food consumption in high-income OECD countries. It accounts for the fact that wealthy nations import significant volumes of fruits, vegetables, and pulses from regions dominated by smallholder agriculture – a dependency invisible in domestic production data.

Key evidence
  • Small farms ( ≤20 ha) contribute ~ 31% of average food consumption in OECD countries, versus 44% in non-OECD countries. Some high-income nations show even higher dependence: Israel ( 49% ), Japan ( 44% ), South Korea ( 41% ).
  • The USA imports ~50% of its vegetables and 18% of its fruits from Mexico; Australia sources 30% of vegetables from India – regions where small-scale farming dominates.
Implications for food systems transformation

This finding complicates simplistic narratives about food system transitions in high-income countries. A shift toward more plant -forward diets in wealthy nations would likely increase dependence on smallholder producers in the Global South for fruits, vegetables, and legumes – raising questions about trade equity, supply chain resilience, and who bears the costs of transition. It suggests that food system transformation strategies must integrate trade policy, smallholder support, and climate adaptation in producing regions, not just demand-side interventions in consuming countries.

Gaps and next steps

The study uses farm-size categories ( ≤20 ha) as a proxy for smallholder agriculture, which may not capture the full complexity of production systems. It does not model future scenarios of dietary shift and their projected impact on trade flows. The vulnerability of these trade-dependent supply chains to climate disruption, trade disputes, or pandemic-related interruptions remains an open question.

8. Evidence from Randomized Trials on Lipid-Lowering by Culinary Herbs and Spices

Goldman, D., & Nagra, M. (2026). Academia Nutrition and Dietetics, 3(1). DOI: 10.20935/AcadNutr8095

KEY TAKEAWAY: Five common herbs and spices – black cumin, garlic, fenugreek, amla, and cinnamon – demonstrate robust cholesterol reductions of 10- 35 mg/dL across 55 independent meta-analyses of RCTs, comparable to dietary fiber interventions, through complementary biochemical mechanisms.

About

This umbrella review synthesizes 55 systematic reviews and meta-analyses of randomized controlled trials examining the cholesterol-lowering effects of ten commonly consumed herbs and spices (black cumin, garlic, fenugreek, amla, cinnamon, ginger, turmeric, saffron, coriander, and black pepper). By aggregating findings across multiple independent research teams, it assesses the reproducibility and consistency of lipid-lowering effects rather than relying on anysingle trial.

Key evidence
  • Five agents demonstrated robust, reproducible cholesterol-lowering effects: total cholesterol reductions of 10-33 mg/dL and LDL-cholesterol reductions of 10-35 mg/dL. These effect sizes are comparable to dietary fiber interventions and were confirmed across multiple independent meta-analyses, strengthening confidence in the findings.
  • These five effective agents operate through complementary biochemical mechanisms, suggesting theoretical cumulative benefits from combining multiple agents, though this has not yet been tested in controlled trials.
  • Garlic and black cumin showed the most consistent evidence across the largest number of independent reviews. Cinnamon, fenugreek, and amla demonstrated meaningful effects but with more variation across study populations and dosing protocols.
Implications for food systems transformation

The strategic relevance here lies in enhancing the appeal and health benefits of plant-based dietary patterns. These are culturally embedded, widely available, and low-cost ingredients – not novel supplements – which positions them as practical tools for addressing palatability and adherence barriers that limit sustained dietary change.

For plant -forward food service and product development, incorporating these ingredients could create both health differentiation and cultural resonance, particularly in culinary traditions where many of these spices are already central. The evidence also supports non-pharmacologic lipid management as a complement to dietary patterns, which may be relevant for public health messaging that connects plant -forward eating to cardiovascular risk reduction.

Gaps and next steps

Individual trial quality varies considerably across the 55 reviewed meta-analyses, and most underlying RCTs used supplemental doses rather than culinary quantities. The critical unanswered question is whether typical cooking amounts deliver clinically meaningful effects. No trials have tested combinations of multiple agents despite the theoretical rationale. The practical significance for population-level health improvement depends on whether these ingredients can be incorporated into everyday cooking at sufficient and consistent levels – a behavioral question current clinical literature does not address.

Reports

1. The Meat of the Matter: What Does the Trend in Lower Meat Consumption Mean for UK Livestock Farmers?

Green Alliance (2026). Policy report. Link

This policy analysis examines 20 years of UK consumption and production data, revealing that declining domestic meat consumption has not reduced domestic production because export growth has absorbed the gap.

The central finding: UK grazing livestock farms (beef and lamb ) lose money on meat production itself and are sustained by subsidies, while intensive pork and poultry operations remain profitable. Average upland farm income of £35,000 could increase by approximately 50% through public goods payments for carbon sequestration and nature restoration on the same land. This finding provides a farmer-economic-centered reframing for dietary shift advocacy – “this improves your profitability” – that is fundamentally different from environmental or ethical arguments.

The report identifies a 2027 policy window as the UK’s Basic Payment Scheme subsidy ends. An important strategic distinction emerges: grazing livestock needs incentive-based transition (already unprofitable on meat alone), while intensive livestock requires regulatory intervention (profitable and will not change voluntarily). UK -specific, but the production-consumption decoupling finding – that domestic demand reduction alone will not deliver environmental benefits without accompanying production-side policy – has global implications.

2. The $540B Grocery Bill: Unlocking the Hidden Value of Food Waste to Drive Growth and Profitability

Avery Dennison (2026). Industry report. Link

This report synthesizes retail executive survey data across seven markets, identifying supply chain inefficiencies driving $540 billion in annual global food waste.

  • Meat represents 50% of retail waste opportunities. The report documents key inefficiencies: lack of visibility ( 61% ), collaboration failures ( 68% ), and transit issues (56% ). While methodological limitations are significant – commercial source, no peer review, undisclosed sample size and calculations – the core claim that meat is the largest retail waste category is supported by independent peer-reviewed research.
  • Meat waste produces 1.7- 2.5x more methane than plant waste and represents 58% of landfill methane despite constituting 24% of material (EPA 2023).

The report is notable for quantifying meat’s outsized waste impact while systematically excluding plant -based alternatives from its solutions framework – treating dietary composition as a fixed constraint rather than an intervention pathway. Strategic value lies in reframing plant -based transition as a waste reduction strategy for business audiences motivated by profitability.
