Browse randomized trials, observational studies, cost models, systematic reviews, and policy guidance. The library includes positive, mixed, and null findings so clinicians, benefit leaders, and members can see what the evidence supports—and where uncertainty remains.
Food Is Medicine is promising, but not uniform. The useful question is not whether every intervention works the same way. It is which model, for which population, over what period, with what clinical support.

Across trials and reviews, these are the outcomes with the clearest repeated gains. They are important outcomes, but they are not the same as proving a clinical or cost result.
Some studies report fewer hospitalizations, lower spending, or better biomarkers. Others find no significant change. Study design and population shape the result.
Intervention intensity, duration, clinical support, eligibility, and the needs of the population can change what a Food Is Medicine program achieves.
Medically tailored meal recipients had roughly half the inpatient admissions and fewer skilled-nursing admissions than matched non-recipients, with lower overall medical spending.
In food-insecure adults with type 2 diabetes, 12 weeks of meals nearly doubled diet quality (HEI 71 vs. 40), cut food insecurity, and reduced self-reported hypoglycemia.
Across 11 health systems and 3,238 Medicaid members, MTM receipt was associated with 31% fewer hospitalizations, 20% fewer ED visits, and $3,433 lower healthcare costs — offsetting 98% of program cost.
A pragmatic RCT of 1,977 patients. Ten weeks of post-discharge meals did not reduce all-cause hospitalization, but exploratory analyses showed lower mortality and fewer heart-failure hospitalizations.
A matched-cohort study after CHF hospitalization. Participants trended toward better blood-pressure categories and healthier intake, though the small pilot did not reach statistical significance.
A Medicaid-population pilot pairing meals with nutrition therapy cut food insecurity from 53% to 17% and established feasibility for at-risk diabetes patients.
Reviewed 14 U.S. RCTs. Food Is Medicine programs consistently improved diet quality and food security — the theorized drivers of better outcomes — while effects on clinical biomarkers were inconsistent, underscoring the need for larger, longer trials.
A rigorous RCT of an intensive grocery-plus-clinical program increased engagement with preventive care, but did not improve glycemic control vs. usual care — a key reminder that program design matters.
In 2,155 patients, an $80/month produce subsidy alone did not improve A1c or utilization at 12 months — evidence that food access works best paired with clinical support, not in isolation.
Among Medicaid adults with chronic conditions, weekly home-delivered produce plus dietitian coaching improved diet quality and loneliness vs. SNAP-only, and cut food insecurity 17% over a year.
A landmark 500-patient RCT of Geisinger’s household-scale, dietitian-prescribed fresh-food program for food-insecure diabetics — one of the most cited operational models in the field.
Modeled across every state, MTM coverage was net cost-saving in the first year in 49 of 50 states — driven by a projected 47% reduction in hospitalizations.
National coverage for eligible patients could avert an estimated 1.6 million hospitalizations and save $13.6 billion in healthcare spending in a single year.
National produce prescriptions for adults with diabetes and food insecurity could prevent 292,000 cardiovascular events and were highly cost-effective at $18,100 per quality-adjusted life-year.
Food Is Medicine programs could generate an estimated $45 billion in economic activity nationwide while creating new demand for local farms and communities.
The AHA’s first presidential advisory on Food Is Medicine — a call to integrate food interventions into clinical care and build a definitive national research base.
A comprehensive clinical review of the FIM spectrum — meals, groceries, produce prescriptions — with evidence on diet quality, glucose, hypertension, and cost-effectiveness, plus guidance for clinicians and payers.
Maps the Food Is Medicine intervention pyramid — from population diet guidance to medically tailored meals — and what scaling it means for the food system.
A field-defining roadmap that catalogs the peer-reviewed evidence base and sets 18 recommendations for how future FIM research should be designed, funded, and evaluated.
A practical policy toolkit from Harvard’s Center for Health Law & Policy Innovation on how states and managed-care plans can fund and scale produce prescriptions through Medicaid.
A bipartisan working group, co-chaired by former cabinet secretaries, makes 10 recommendations to scale evidence-based FIM interventions and strengthen clinical nutrition education.
A foundational white paper synthesizing the early MTM evidence base — including Project Angel Heart, Project Open Hand, and MANNA — that helped open Medicaid and Medicare Advantage coverage pathways.
The federal Food Is Medicine initiative, launched after the 2022 White House Conference on Hunger, Nutrition, and Health, to scale access nationwide.
This is a curated, growing library—not the entire field. We include null and mixed-result trials alongside positive ones because honest evidence is the point. Findings are summarized from each study’s published abstract; follow the source for full methods, limitations, and context.
We stand on their work. For the full bodies of research, start with the organizations defining Food Is Medicine — led by the team at Tufts.
The leading academic home of Food Is Medicine, based at Tufts’ Friedman School. Runs the largest FIM clinical trials, cost-effectiveness modeling, and policy analysis in the field — the definitive starting point for the science.
The AHA’s national initiative funding the next generation of FIM clinical trials and building the evidence base payers need to reimburse food-based interventions.
Has committed more than $100 million since 2019 to advance FIM research, infrastructure, and policy in partnership with HHS, the VA, and the American Heart Association.
The national coalition of nonprofit medically tailored meal providers, with a continually updated library of published and in-process research and the field’s MTM standards.
Author of the Food Is Medicine Research Action Plan, the roadmap cataloging the evidence base and setting research priorities for the field.
The Center for Health Law & Policy Innovation produces the policy toolkits that help states and Medicaid plans fund and scale produce prescriptions and medically tailored meals.
An integrated-health-system center bringing FIM screening, produce prescriptions, and medically tailored meals to members at scale while measuring outcomes and costs.
Boston-based nonprofit and the largest medically tailored meal provider in the Massachusetts Medicaid demonstration, and a long-standing research partner behind the foundational MTM evidence.
Convened a bipartisan Food Is Medicine working group whose recommendations are shaping federal coverage and nutrition-education policy.
State-level research and advocacy advancing Food Is Medicine within Medicaid and managed-care programs.
