Food as Medicine programs are healthcare-integrated nutritional interventions: food, prescribed or referred by health professionals, delivered to treat, manage, or prevent diet-related health conditions. The American Heart Association defines the field as the provision of healthy food—produce prescriptions, medically tailored groceries, and medically tailored meals—"in a way that is integrated with and paid for by the health care sector," with patients referred by a clinician, health organization, or insurance plan. What sets these programs apart from ordinary food assistance is that the food is matched to a specific health condition and to social needs such as food insecurity.
What is Food as Medicine?
The Tufts Food is Medicine Institute describes FIM programs as health sector strategies that "prescribe medically tailored meals, groceries, or produce to support disease management and optimal well-being, based on the presence of a specific health condition as well as social needs." That dual trigger—both a medical condition and a social need—is the defining feature. A food bank may feed a hungry family; a Food as Medicine program feeds a person with diabetes or heart disease whose circumstances make a therapeutic diet hard to obtain or maintain.
The federal Office of Disease Prevention and Health Promotion frames the field broadly, describing interventions that "promote optimal health and reduce disease burden by providing nutritious food – with human services, education, and policy change, through collaboration at the nexus of health care and community." Tufts and its partner organizations present FIM as a continuum: at the base, population-level healthy food policies and nutrition security programs like SNAP, WIC, and school meals; in the middle, nutrition counseling and education; at the top, the clinical interventions—produce prescriptions, medically tailored groceries, and medically tailored meals.
Referral is the gateway. Under the American Heart Association's definition, patients reach these services through a health care professional, a health care organization, or a health insurance plan, which is what distinguishes FIM from programs anyone can access directly. The Tufts definition adds that programs typically pair food with culturally appropriate nutrition and culinary education, often delivered digitally.
Types of Food as Medicine Interventions
Three intervention types dominate the clinical end of the continuum, and they are frequently confused. Medically tailored meals (MTMs) provide fully prepared meals designed to meet the dietary requirements of a particular medical condition. Medically tailored groceries (MTGs) provide groceries selected for the same purpose, but the recipient prepares the food themselves. Produce prescription programs (PRx) are narrower still: they provide financial assistance—vouchers or debit cards—for purchasing fruits and vegetables, often alongside nutrition education, according to the National DPP Coverage Toolkit.
The toolkit defines produce prescriptions as the provision of free or discounted produce to ambulatory patients who meet specific eligibility criteria, such as having a chronic condition like diabetes, prediabetes, hypertension, obesity, or heart disease, or who have low incomes or experience food insecurity. Medically tailored meals, by contrast, generally serve people whose conditions and circumstances are more complex—individuals with diet-related chronic diseases and food insecurity whose health can be improved through specific dietary intervention.
Comparing Food as Medicine Interventions
The table below sorts the three clinical interventions by what is actually provided, the intended goal, and who typically receives it—the attributes that most often get blurred when the programs are discussed together.
| Intervention | What is provided | Primary goal | Typical recipient |
|---|---|---|---|
| Medically tailored meals (MTM) | Prepared meals tailored to the dietary requirements of a specific medical condition | Treat or prevent disease, manage chronic conditions, improve health outcomes and reduce healthcare utilization | Individuals with diet-related chronic diseases and food insecurity |
| Medically tailored groceries (MTG) | Groceries selected to support disease management and optimal well-being; recipient prepares the food | Support disease management and optimal well-being | People with a specific health condition and social needs who can cook for themselves |
| Produce prescriptions (PRx) | Vouchers or debit cards for fruits and vegetables, often with nutrition education | Improve dietary intake, food and nutrition security, and disease management | Ambulatory patients with conditions such as diabetes, prediabetes, hypertension, obesity, or heart disease, and/or people with low incomes or food insecurity |
The comparison shows a gradient of intensity. MTMs deliver the most complete support—ready-to-eat, condition-specific food—while PRx delivers the lightest touch: purchasing power for produce plus education. MTGs sit between them, tailoring the food but leaving preparation to the patient. All three fall under the same FIM umbrella and share the same referral pathway through the health sector.
Addressing Chronic Disease and Food Insecurity
The reason these programs exist at all is the scale of diet-related disease. A research review published in 2024 notes that the CDC estimates roughly six in ten American adults are diagnosed with chronic diseases such as diabetes, obesity, cancer, and heart disease, and that this burden strains the healthcare system and drives up costs. The review's central observation about FIM is that unlike conventional food assistance, it "not only addresses food insecurity but also targets chronic diseases by customizing the food delivered to its recipients."
That dual design is deliberate. A person with uncontrolled diabetes who cannot afford or access appropriate food faces two problems at once, and solving only one leaves the medical problem intact. By conditioning the intervention on both a health condition and social needs, FIM programs aim at health equity as well as clinical improvement—the Tufts institute explicitly names advancing health equity as part of its mission.
Evidence is still accumulating. The federal health promotion office reports growing evidence that FIM interventions can improve dietary intake, food and nutrition security, disease management, health outcomes, and healthcare utilization. A 2020 review in the same research tradition cautioned that scaled integration would require significant investment in rigorous research, better clinician education, and sustained funding streams to ensure equitable access—gaps the field is still working to close.
Professional and Policy Context
Registered Dietitian Nutritionists are the professional backbone of the model. The Tufts Food is Medicine Institute states that FIM programs "leverage registered dietitian nutritionist (RDN) expertise" alongside culturally appropriate education. The tailoring that separates a medically tailored meal from an ordinary meal delivery depends on clinical nutrition judgment about what a specific condition requires.
On the policy side, FIM has moved from pilot projects toward federal strategy. The National DPP Coverage Toolkit reports that FIM interventions are "an increasingly important component of federal and state strategies to address increasing rates of diet-related chronic conditions," and the federal health promotion office now maintains its own guidance describing the intervention types and the continuum along which they sit. The Tufts fact sheet, produced collaboratively by partner organizations in 2025, reflects a field consolidating around shared definitions.
The Future of Food as Medicine in Healthcare
Healthcare systems and policymakers should continue to integrate and expand Food as Medicine programs to address diet-related chronic diseases and food insecurity. The measurable indicator to watch is continued growth in the number of FIM programs and demonstrable improvements in health outcomes and food security for participants. For readers trying to make sense of the field today, the framework is simple: if food is referred by the health sector, paid for by the health sector, and matched to a medical condition, it is Food as Medicine—and whether it arrives as a prepared meal, a bag of tailored groceries, or a produce voucher depends on how much support the recipient needs.
