The study, meticulously published in the prestigious journal Nature Food on October 8, 2025, undertook a comprehensive risk assessment of forced labor within the supply chains of over two hundred common foods that typify American diets. Researchers analyzed five distinct dietary patterns: three federally recommended diets—the Healthy U.S.-Style Diet, the Healthy Mediterranean-Style Diet, and the Healthy Vegetarian Diet—as well as the 2019 EAT-Lancet Planetary Health Diet, alongside the current average American diet based on the National Health and Nutrition Examination Survey. This exhaustive evaluation entailed correlating each food’s production characteristics—such as cultivation techniques, geographic origin, harvesting methods, and processing practices—with internationally recognized indicators of forced labor risk.

Forced labor, as defined by the International Labor Organization, includes a spectrum of coercive practices that trap workers in exploitative employment through isolation, oppressive recruitment debt, withheld wages, and abusive or hazardous conditions. The study integrated these criteria with data from the Social Hotspots Database and other labor rights resources to generate a nuanced risk profile for each food item, highlighting how modern food systems, despite promoting healthful eating, may inadvertently perpetuate human rights violations at the labor level.

One of the study’s pivotal findings is that the forced labor risk associated with dietary patterns fluctuates primarily due to the relative consumption of fruits, dairy products, and red meat. Protein sources emerged as the dominant contributors to forced labor risk across the evaluated diets, yet the drivers of such risk differ significantly based on the type of protein and production process. Specifically, livestock farming-related risks were comprehensively accounted for, including those linked to feed production, animal slaughter, and meat processing operations. Alarmingly, the fishing sector was identified as maintaining a substantially heightened forced labor risk compared to other food production sectors, underscoring vulnerabilities intrinsic to maritime labor conditions.

Fruits such as berries and other varieties that necessitate manual harvesting—and nuts requiring labor-intensive shelling procedures—were additionally highlighted as elevated risk commodities. This reflects the entrenched reliance on hand labor in sectors where machine harvesting is less feasible, and where workers are often subjected to exploitative employment structures. Such complexity brings forth nuanced challenges in aligning ethical labor practices with sustainable diet recommendations.

The Healthy Mediterranean-Style Diet, characterized by a predominance of plant-based foods, seafood, moderate dairy, and red meat consumption, alongside the Healthy U.S.-Style Diet—which emphasizes a diverse nutrient-dense food profile with a relatively substantial intake of dairy—demonstrated a higher collective forced labor risk than the current average American diet. In these patterns, the convergence of dairy, red meat, and seafood was elucidated as significantly elevating labor exploitation risk profiles. Similarly, fruit consumption also contributed to this heightened risk panorama, particularly in the Mediterranean pattern, indicating a complex interplay between health-conscious eating and labor justice.

Conversely, the Healthy Vegetarian Diet and the EAT-Lancet Planetary Health Diet, both emphasizing plant-based ingredients with limited animal product inclusion, evidenced comparatively lower forced labor risks. However, these diets were not devoid of risk, with nuts and seeds identified as sources of outsized labor exploitation vulnerabilities. This underscores that even predominantly plant-based diets are not immune to ethical supply chain complexities and require careful scrutiny to ensure responsible sourcing and worker protections.

The implications of these findings transcend individual consumer choices, bearing substantial ramifications for large-scale food purchasing policies and public health strategies. Given that dietary guidelines influence the nutritional standards of millions through institutional programs such as school meals, government food procurement, and city-level sustainability initiatives, incorporating forced labor risk assessments into policy frameworks represents a critical frontier in advancing food justice.

Lead researchers emphasize that eradication of forced labor within food systems necessitates worker empowerment and institutional accountability. Legal mechanisms enforcing worker protections, binding agreements preventing retaliation, and participatory governance models are central to fostering sustainable and equitable labor standards. Programs like the Fair Food Program exemplify how direct worker involvement can catalyze meaningful change, offering scalable models for reform.

Furthermore, international trade regulations restricting imports tainted by forced labor are vital in reshaping global commodity chains. Such measures can incentivize corporations to adopt higher social responsibility standards and inhibit unfair competition derived from exploitative practices, ultimately contributing to leveling the field for ethical production.

This study represents a seminal contribution to the emerging discourse at the intersection of nutrition, ethics, and labor rights. By uncovering the hidden human costs embedded within current dietary paradigms, the research encourages a holistic reconsideration of food policy—where health, sustainability, and social justice are integrated imperatives. It invites stakeholders across government, industry, and civil society to collaboratively engineer food systems that safeguard workers’ dignity while promoting public health and planetary well-being.

In sum, as consumers increasingly prioritize health and environmental stewardship in their food choices, it is imperative that these values extend beyond nutrition to encompass the ethical dimensions of labor. Recognizing and addressing the persistent prevalence of forced labor in food supply chains is not merely a moral obligation but a foundational step toward truly sustainable and just food systems.

A staggering 90 percent of the respondents acknowledged the critical role of healthy eating in preventing chronic diseases, such as obesity, hypertension, and type-2 diabetes. Despite this recognition, the survey revealed a concerning gap in public understanding and experience with the Food is Medicine approach, as fewer than 30 percent had heard of this transformative movement. The paradox is apparent; while knowledge of the movement may be low, there is a noticeable willingness to engage with it. Over half of the participants expressed interest in exploring options such as produce prescriptions, medically tailored groceries, and meal programs when offered through healthcare providers.

Interestingly, the survey illuminates a stark divide in the engagement of healthcare providers with nutrition-related discussions. The findings indicated that only one in four respondents had their primary care providers inquire about food security. Furthermore, dialogues surrounding dietary habits were reported in fewer than half of clinical encounters. This disconnect is alarming, as it suggests a critical gap in the integration of nutritional assessment and support within the clinical practice framework, ultimately impacting patient care.

The lack of nutrition education in medical training was highlighted as a significant barrier for healthcare providers. Many practitioners feel unequipped to broach topics related to food insecurity and dietary habits due to insufficient training and a lack of time during patient consultations. The researchers observed that many healthcare providers are hesitant to initiate conversations about food, often unsure about the appropriate resources to direct patients toward when issues of nutrition arise. As these conversations are pivotal for enhancing patient outcomes, there is an urgent need for structural changes that support providers in facilitating these discussions.

Demands for food-based therapeutic interventions are reflected in the survey results. Roughly half of American adults indicated they would be more inclined to make positive dietary changes if they had regular discussions with their healthcare providers about their habits. Notably, over 80 percent of participants affirmed that they would be motivated to eat healthier if they comprehended the potential benefits for their overall well-being. However, financial barriers remain a critical obstacle, with 83 percent identifying the cost of healthy foods as the foremost hindrance to dietary improvements. The urgency of addressing these barriers cannot be overstated, particularly as over half of the surveyed individuals believe that healthcare systems should help provide or reimburse healthy food options.

The survey also identified prevalent hurdles that deter healthy eating. Family traditions that revolve around unhealthy eating patterns were noted by 79 percent of respondents, while 57 percent lamented the lack of healthy food options available in their shopping environments. Accessibility emerged as another significant concern, with over half indicating that there are not enough stores or food pantries offering healthy choices nearby. Additionally, nearly half of respondents expressed uncertainty regarding what constitutes healthy food, further complicating efforts to adopt better dietary practices.

Dariush Mozaffarian, a senior author of the study and director of the Food is Medicine Institute, emphasized the findings, stating, "There’s a misconception that many people don’t want to eat nourishing foods, or that they prefer unhealthy products—but our new results highlight that most Americans want to eat better but face specific barriers and challenges." This reinforces the critical narrative that demand exists for greater access to food as medicine strategies as part of healthcare, indicative of a pressing need for collaborative policies that address healthcare inequities.

Following the survey, researchers are actively engaging with policymakers through initiatives such as the 2nd Annual Food is Medicine Advocacy Day on Capitol Hill. During this event, they will advocate for bolstering the infrastructure surrounding Food is Medicine initiatives within the healthcare system. Proposed measures include enhancing nutrition-related training for medical professionals, fostering innovative research on Food is Medicine through institutions like the National Institutes of Health, and expanding coverage for food programs via Medicare and Medicaid.

Stakeholders in this dialogue are driven by the conviction that nutritional interventions can significantly contribute to a more holistic and cost-effective approach to healthcare. With evidence-backed advocacy, the potential for systemic change looms large. Learning how food can serve as a preventative measure against disease opens a gateway to improved health outcomes for populations across America.

In the weeks preceding the survey’s publication, the researchers secured funding from entities such as the Kaiser Permanente East Bay Community Fund, demonstrating support from established organizations that recognize the value of integrating nutrition into healthcare strategies. The study’s detailed methodology, including limitations and conflicts of interest, has been transparently documented, showcasing the research team’s commitment to integrity and rigor.

Through this pioneering report, Tufts University and its researchers have illuminated the significance of nutrition within the healthcare landscape. As the Food is Medicine movement gains momentum, time-sensitive collaboration between healthcare providers, policymakers, and the public is essential for fostering an environment where nutritious food becomes an integral aspect of primary healthcare offerings.

The implications of the survey extend beyond mere statistics; they compel us to consider how society can foster greater awareness, education, and accessibility regarding healthy food. Thus, comprehensive policies that align nutrition and healthcare are not only beneficial but essential for improving the health trajectory of future generations.

Ultimately, the results of this survey reveal not just the state of public perception surrounding Food is Medicine programs, but also a call to action for healthcare providers and policymakers to acknowledge and address the systematic barriers that prevent individuals from accessing the nourishing foods they need to thrive.
