Healthy Food Prescription Programs and their Impact on Dietary Behavior and Cardiometabolic Risk Factors: A Systematic Review and Meta-Analysis

The enormous burden of diet-related chronic diseases has prompted interest in healthy food prescription programs. Yet, the impact of such programs remains unclear. The aim of this study was to conduct a systematic review of healthy food prescription programs and evaluate their impact on dietary behavior and cardiometabolic parameters by meta-analysis. A systematic search was carried out in Medline, Embase, Scopus, and Cochrane Central Register of Controlled Trials databases since their inception to 3 January, 2020 without language restriction. A systematic search of interventional studies investigating the effect of healthy food prescription on diet quality and/or cardiometabolic risk factors including BMI, systolic (SBP) and diastolic blood pressure (DBP), glycated hemoglobin (HbA1c), or blood lipids was carried out. Thirteen studies were identified for inclusion, most of which were quasi-experimental (pre/post) interventions without a control group (n = 9). Pooled estimates revealed a 22% (95% CI: 12, 32; n = 5 studies, n = 1039 participants; I2 = 97%) increase in fruit and vegetable consumption, corresponding to 0.8 higher daily servings (95% CI: 0.2, 1.4; I2 = 96%). BMI decreased by 0.6 kg/m2 (95% CI: 0.2, 1.1; I2 = 6.4%) and HbA1c by 0.8% (95% CI: 0.1, 1.6; I2 = 92%). No significant change was observed in other cardiometabolic parameters. These findings should be interpreted with caution in light of considerable heterogeneity, methodological limitations of the included studies, and moderate to very low certainty of evidence. Our results support the need for well-designed, large, randomized controlled trials in various settings to further establish the efficacy of healthy food prescription programs on diet quality and cardiometabolic health.

Promoting Healthy Food Access and Nutrition in Primary Care: A Systematic Scoping Review of Food Prescription Programs

OBJECTIVE

To conduct a scoping review to synthesize evidence on food prescription programs.

DATA SOURCE

A systematic search of PubMed, CINAHL, Web of Science, Embase, and the Cochrane Library was conducted using key words related to setting, interventions, and outcomes.

STUDY INCLUSION AND EXCLUSION CRITERIA

Publications were eligible if they reported food prescription administered by a health care practitioner (HCP) with the explicit aim of improving healthy food access and consumption, food security (FS), or health.

DATA EXTRACTION

A data charting form was used to extract relevant details on intervention characteristics, study methodology, and key findings.

DATA SYNTHESIS

Study and intervention characteristics were summarized. We undertook a thematic analysis to identify and report on themes. A critical appraisal of study quality was conducted using the Mixed Methods Appraisal Tool (MMAT).

RESULTS

A total of 6145 abstracts were screened and 23 manuscripts were included in the review. Food prescriptions may improve fruit and vegetable consumption and reduce food insecurity (FI). Evidence for impacts on diet-related health outcomes is limited and mixed. The overall quality of included studies was weak. Addressing barriers such as stigma, transportation, and poor nutrition literacy may increase utilization of food prescriptions.

CONCLUSION

Food prescriptions are a promising health care intervention. There is a need for rigorous studies that incorporate larger sample sizes, control groups, and validated assessments of dietary intake, food security, and health.

A Systematic Scoping Review of How Healthcare Organizations Are Facilitating Access to Fruits and Vegetables in Their Patient Populations

BACKGROUND

There is compelling evidence on the impact of diet as preventative medicine, and with rising health care costs healthcare organizations are attempting to identify interventions to improve patient health outcomes.

OBJECTIVES

The purpose of this systematic scoping review was to characterize existing healthcare organization-based interventions to improve access to fruits and vegetables (F&V) for their patient populations. In addition, we aimed to review the impact of identified interventions on dietary intake and health outcomes.

METHODS

Titles and abstracts were searched in PubMed® (MEDLINE®), Embase®, CINAHL®, and the Cochrane Library® from 1 January 1990 to 31 December 2019. To be selected for inclusion, original studies must have included a healthcare organization and have had a programmatic focus on increasing access to or providing fresh F&V to patients in an outpatient, naturalistic setting. The Effective Public Health Practice Project tool was used to assess study quality in 6 domains (selection bias, study design, confounders, blinding, data collection methods, and withdrawals and dropouts).

RESULTS

A total of 8876 abstracts were screened, yielding 44 manuscripts or abstracts from 27 programs. Six program models were identified: 1) a cash-back rebate program, 2) F&V voucher programs, 3) garden-based programs, 4) subsidized food box programs, 5) home-delivery meal programs, and 6) collaborative food pantry-clinical programs. Only 6 of 27 studies included a control group. The overall quality of the studies was weak due to participant selection bias and incomplete reporting on data collection tools, confounders, and dropouts. Given the heterogeneity of outcomes measured and weak study quality, conclusions regarding dietary and health-related outcomes were limited.

CONCLUSIONS

Healthcare-based initiatives to improve patient access to F&V are novel and have promise. However, future studies will need rigorous study designs and validated data collection tools, particularly related to dietary intake, to better determine the effect of these interventions on health-related outcomes.

Teaching Kitchens in the Learning and Work Environments: The Future Is Now

The learning and working environments of today's hospitals and health systems are designed to predict, diagnose, treat, and manage disease. However, the food environments in these settings are often extraordinarily unappealing, unhealthy, and can adversely impact the well-being of health professionals. What if future health-care sites were designed as showrooms of the most appealing and nutritious foods? What if future cafeterias included ventilated "Teaching Kitchens" as extensions to the everyday "grab and go" check-out lines? What if health-care providers, trainees, staff, and community members had access to foods that were healthy, delicious, affordable, sustainable, and easy to prepare? Most importantly, what if health professionals learned to make these healthy, delicious recipes as part of their required training? "See one, do one, teach one" could become, "See one, taste one, make one, teach one". Teaching Kitchens could serve as both learning laboratories and clinical research centers, whereby teaching kitchen curricula could be tested, through sponsored research, for their impact on behaviors, clinical outcomes, and costs. What if spaces adjacent to Teaching Kitchens were designated "Mindful Eating Spaces," where self-selected patrons could enjoy a "Culinary Feast alongside a Technological Fast" in an effort to carve out a brief oasis of mindful, resilience-building reflection during any given day? This article describes the rationale for and necessary components of such a futurist "Teaching Kitchen" within future working and learning environments. Importantly, if and when Teaching Kitchens are built within health-care settings, they may serve as catalysts of personal and societal health enhancement for all.

Health and Economic Impacts of Implementing Produce Prescription Programs for Diabetes in the United States: A Microsimulation Study

Background Produce prescription programs, providing free or discounted produce and nutrition education to patients with diet-related conditions within health care systems, have been shown to improve dietary quality and cardiometabolic risk factors. The potential impact of implementing produce prescription programs for patients with diabetes on long-term health gains, costs, and cost-effectiveness in the United States has not been established. Methods and Results We used a validated state-transition microsimulation model (Diabetes, Obesity, Cardiovascular Disease Microsimulation model), populated with national data of eligible individuals from the National Health and Nutrition Examination Survey 2013 to 2018, further incorporating estimated intervention effects and diet-disease effects from meta-analyses, and policy- and health-related costs from published literature. The model estimated that over a lifetime (mean=25 years), implementing produce prescriptions in 6.5 million US adults with both diabetes and food insecurity (lifetime treatment) would prevent 292 000 (95% uncertainty interval, 143 000-440 000) cardiovascular disease events, generate 260 000 (110000-411 000) quality-adjusted life-years, cost $44.3 billion in implementation costs, and save $39.6 billion ($20.5-58.6 billion) in health care costs and $4.8 billion ($1.84-$7.70 billion) in productivity costs. The program was highly cost effective from a health care perspective (incremental cost-effectiveness ratio: $18 100/quality-adjusted life-years) and cost saving from a societal perspective (net savings: $-0.05 billion). The intervention remained cost effective at shorter time horizons of 5 and 10 years. Results were similar in population subgroups by age, race or ethnicity, education, and baseline insurance status. Conclusions Our model suggests that implementing produce prescriptions among US adults with diabetes and food insecurity would generate substantial health gains and be highly cost effective.

Testing the Feasibility and Dietary Impact of a "Produce Prescription" Program for Adults with Undermanaged Type 2 Diabetes and Food Insecurity in Australia

BACKGROUND

There is growing interest in Food is Medicine programs that incorporate food-based interventions into health care for patients with diet-related conditions.

OBJECTIVES

We aimed to test the feasibility of a "produce prescription" program and its impact on diet quality for people with type 2 diabetes (T2D) experiencing food insecurity in Australia.

METHODS

We conducted a pre-post intervention study in n = 50 adults experiencing food insecurity with T2D and glycated hemoglobin (HbA1c) ≥8%. Once enrolled, participants received healthy food boxes weekly free of charge, with the contents sufficient to create 2 meals/d, 5 d/wk for the entire household, over 12 wk. Participants were also provided with tailored recipes and behavioral change support. The primary outcome was change in diet quality assessed by 24-h diet recalls. Secondary outcomes included differences in cardiovascular disease risk factors; blood micronutrients; and feasibility indicators. Differences in the baseline and 12-wk mean primary and secondary outcomes were assessed by paired t tests.

RESULTS

Participants were older adults with mean ± SD age 63 ± 9 y (range: 40-87 y), HbA1c 9.8% ± 1.5%, and 46% were female. Overall, 92% completed the final study follow-up for the primary outcome. Compared with baseline, diet quality improved at week 12, with an increase in the mean overall diet quality (Alternate Healthy Eating Index score) of 12.9 (95% CI: 8.7, 17.1; P < 0.001), driven by significant improvements in vegetables, fruits, whole grains, red/processed meat, trans fat, sodium, and alcohol consumption. Blood lipids also improved (total:HDL cholesterol: -0.48; 95% CI: -0.72, -0.24; P < 0.001), and there was significant weight loss (-1.74 kg; 95% CI: -2.80, -0.68 kg, P = 0.002), but no changes in other clinical outcomes. Participants reported high levels of satisfaction with the program.

CONCLUSIONS

These findings provide strong support for an adequately powered randomized trial to assess effects of produce prescription as an innovative approach to improve clinical management among individuals with T2D experiencing food insecurity. This trial was registered at https://anzctr.org.au/ as ACTRN12621000404820.

A Rural Delivery-Based Produce Prescription Intervention Improves Glycemic Control and Stress

OBJECTIVE

We examined the impact of a pilot 24-week delivery-based produce prescription (PRx) intervention with tailored education and culinary resources for rural patients (n = 40) with type-2 diabetes in underresourced communities on behavioral and clinical outcomes.

METHODS

We used a single group pretest-posttest design that included a home-delivered PRx, culturally tailored recipes, and health/nutrition education handouts. Measures included hemoglobin A1c (HbA1c), self-reported fruit/vegetable consumption, and stress. Descriptive statistics, t-tests, and Wilcoxon signed rank tests were conducted.

RESULTS

Mean HbA1c decreased from 7.6 ± 1.6% to 7.1% ± 1.4% (P = 0.001). Self-reported consumption of fruit/vegetables improved, including frequency and serving size of beans (P = 0.01 and P = 0.01), serving size of lettuce salad (P = 0.02), and serving size of vegetable soup (P = 0.001). Perceived stress decreased (P = 0.01).

CONCLUSION AND IMPLICATIONS

Findings from this pilot PRx intervention suggest a delivery-based PRx with tailored educational resources has the potential to reduce HbA1c and stress while improving fruit/vegetable consumption within rural patients with type-2 diabetes in underresourced communities.

A Case for Using Electronic Health Record Data in the Evaluation of Produce Prescription Programs

Produce prescription programs within clinical care settings can address food insecurity by offering financial incentives through "prescriptions" for fruits and vegetables to eligible patients. The electronic health record (EHR) holds potential as a strategy to examine the relationship between these projects and participant outcomes, but no studies address EHR extraction for programmatic evaluations. We interviewed representatives of 9 grantees of the U.S. Department of Agriculture's Gus Schumacher Nutrition Incentive Grant Program's Produce Prescription Projects (GusNIP PPR) to understand their experiences with and capacity for utilizing EHR for evaluation. Five grantees planned to use EHR data, with 3 main strategies: reporting aggregate data from health clinics, contracting with external/third party evaluators, and accessing individual-level data. However, utilizing EHRs was prohibitive for others due to insufficient knowledge, training and/or staff capacity; lack of familiarity with the Institutional Review Board process; or was inappropriate for select target populations. Policy support for produce prescription programs requires a robust evidence base, deep knowledge of best practices, and an understanding of expected health outcomes. These insights can be most efficiently and meaningfully achieved with EHR data, which will require increased financial support and technical assistance for project operators.

Advancing nutrition knowledge, skills, and attitudes in medical education and training: key themes and recommendations from the 2023 Summit

The incorporation of comprehensive nutrition education into medical education and training is essential for equipping physicians with the knowledge and skills necessary to enhance patient health and outcomes. However, a deficiency in nutrition education persists in medical education, rendering physicians ill-prepared to address the vital role of nutrition in health and disease. This article summarizes the key themes and recommendations generated during the Summit on Medical Education in Nutrition, hosted in March 2023 by the Accreditation Council for Graduate Medical Education in collaboration with American Association of Colleges of Osteopathic Medicine and Association of American Medical Colleges.

The Role of Agricultural Systems in Teaching Kitchens: An Integrative Review and Thoughts for the Future

Diet-related chronic disease is a public health epidemic in the United States. Concurrently, conventional agricultural and food production methods deplete the nutritional content of many foods, sever connections between people and the origin of their food, and play a significant role in climate change. Paradoxically, despite an abundance of available food in the US, many households are unable to afford or attain a healthful diet. The linkages between agriculture, health, and nutrition are undeniable, yet conventional agriculture and healthcare systems tend to operate in silos, compounding these pressing challenges. Operating teaching kitchens in collaboration with local agriculture, including farms, community gardens, vertical farms, and urban agriculture, has the potential to catalyze a movement that emphasizes the role of the food system in promoting human and planetary health, building resilient communities, and encouraging cross-disciplinary collaboration. This paper reviews the current state of agricultural systems, food is medicine, consumer behavior, and the roles within these sectors. This is followed by a series of case studies that fill the gaps between TKs and agriculture. The authors summarize opportunities to combine the knowledge and resources of teaching kitchens and agriculture programs, as well as challenges that may arise along the way.

Implementation of Food is Medicine Programs in Healthcare Settings: A Narrative Review

Food is Medicine (FIM) programs to improve the accessibility of fruits and vegetables (FVs) or other healthy foods among patients with low income and diet-related chronic diseases are promising to improve food and nutrition security in the United States (US). However, FIM programs are relatively new and implementation guidance for healthcare settings using an implementation science lens is lacking. We used a narrative review to describe the evidence base on barriers and facilitators to FIM program integration in US healthcare settings following the Exploration, Preparation, Implementation, and Sustainment (EPIS) Framework. Evidence surrounding the EPIS Inner Context was a focus, including constructs Leadership, Organizational Characteristics, Quality and Fidelity Monitoring and Support, Organizational Staffing Processes, and Individual Characteristics. Peer-reviewed and grey literature about barriers and facilitators to FIM programs were of interest, defined as programs that screen and refer eligible patients with diet-related chronic disease experiencing food insecurity to healthy, unprepared foods. Thirty-one sources were included in the narrative review, including 22 peer-reviewed articles, four reports, four toolkits, and one thesis. Twenty-eight sources (90%) described EPIS Inner Context facilitators and 26 sources (84%) described FIM program barriers. The most common barriers and facilitators to FIM programs were regarding Quality and Fidelity Monitoring and Support (e.g., use of electronic medical records for tracking and evaluation, strategies to support implementation) and Organizational Staffing Processes (e.g., clear delineation of staff roles and capacity); although, barriers and facilitators to FIM programs were identified among all EPIS Inner Context constructs. We synthesized barriers and facilitators to create an EPIS-informed implementation checklist for healthcare settings for use among healthcare organizations/providers, partner organizations, and technical assistance personnel. We discuss future directions to align FIM efforts with implementation science terminology and theories, models, and frameworks to improve the implementation evidence base and support FIM researchers and practitioners.

Food Is Medicine for Individuals Affected by Homelessness: Findings from a Participatory Soup Kitchen Menu Redesign

Health disparities among people experiencing homelessness are likely exacerbated by limited access to healthy, fresh, and minimally processed foods. Soup kitchens and shelters serve as essential food safety nets for preventing hunger in this population, and community interest is growing in the potential of "food is medicine" interventions to improve the mental and physical wellbeing of people who receive meals from these providers. This study describes our two-phase approach to first identify and prioritize nutrition needs within an urban soup kitchen community and then test and implement new recipes and menu guidelines to help the standard soup kitchen menu better align with those priorities. We began by first conducting a nutrition needs assessment, including a collection of intercept surveys from a convenience sample of soup kitchen guests to better understand their nutrition-related health needs, dental issues, food preferences, and menu satisfaction (n = 112), as well as a nutrition analysis of the standard menu based on seven randomly selected meals. Most respondents reported at least one chronic health condition, with depressive disorders (50.9%) and cardiovascular diseases (49.1%) being the most common. Nearly all guests requested more fruits and vegetables at mealtimes, and results from the menu analysis revealed opportunities to lower meal contents of sodium, saturated fat, and added sugars and to raise micronutrient, fiber, and omega-3 content. We then applied these nutrition needs assessment findings to inform the second phase of the project. This phase included the identification of new food inventory items to help support cardiovascular and mental health-related nutrition needs, taste test sampling of new healthy menu items with soup kitchen guests, and hands-on culinary medicine training to kitchen staff on newly-developed "food is medicine" guidelines to support menu transformation. All taste tests of new menu items received over 75% approval, which exceeded satisfaction ratings of the standard menu collected during the phase 1 needs assessment. Findings from this community-based participatory research project confirm the great potential for hunger safety net providers to support critical nutrition needs within this vulnerable population through strategic menu changes. However, more research is needed on the longitudinal impacts of such changes on health indicators over time.

How a Medically Tailored Meal Intervention with Intensive Nutrition Counseling Created Active Coping with Behavior Change for Vulnerable Patients with Lung Cancer

Purpose

The purpose of this study was to assess participants' perceptions and experiences while participating in a Food is Medicine medically tailored meal plus nutrition counseling intervention to create a theoretical explanation about how the intervention worked.

Methods

This interpretive qualitative study included the use of semi-structured interviews with active intervention participants. Purposeful sampling included vulnerable (uninsured, rural zip code residency, racial/ethnic minority, 65 years old, and/or low-income) individuals with lung cancer treated at four cancer centers across the United States. Interviews were recorded, transcribed verbatim, and analyzed using conventional content analysis with principles of grounded theory.

Results

Twenty individuals participated. Data analysis resulted in a theoretical explanation of the intervention's mechanism of action. The explanatory process includes 3 linked and propositional categories leading to patient resilience: engaging in treatment, adjusting to diagnosis, and active coping. The medically tailored meals plus intensive nutrition counseling engaged participants throughout treatment, which helped participants adjust to their diagnosis, leading to active coping through intentional self-care, behavior change, and improved quality of life.

Conclusions

These findings provide evidence that a food is medicine intervention may buffer some of the adversity related to the diagnosis of lung cancer and create a pathway for participants to experience post-traumatic growth, develop resilience, and change behaviors to actively cope with lung cancer. Medically tailored meals plus intensive nutrition counseling informed by motivational interviewing supported individuals' adjustment to their diagnosis and resulted in perceived positive behavior change.

Food is Medicine Interventions and Climate Change

Food is Medicine (FiM), also known as Food as Medicine, integrates food and nutrition interventions into health care delivery with the primary goal to improve population health and address diet-related health conditions. To date, there has been little focus on the relation between FiM and climate change despite FiM's involvement with 2 key drivers of climate change: health care delivery and food systems. FiM may be able to advance lifestyle medicine and population health objectives, as well as mitigate some of the health care and food-related drivers of climate change, by focusing on 4 key areas: (1) Increasing the absolute number and proportion of patients who follow plant-based diets; (2) reducing food waste; (3) reducing unnecessary health care utilization; and (4) lowering transportation-related greenhouse gas emissions related to food procurement. Measuring the ecological impact of FiM alongside clinical, utilization, and financial measures will require a different analytical approach than that used traditionally in health care. Ultimately, thoughtful, data-driven, and urgent interventions that span the food and health care sectors are needed to sustainably support not only FiM, but human, environmental, and planetary health as well.

Standard Patient History Can Be Augmented Using Ethnographic Foodlife Questions

The relationship between what and how individuals eat and their overall and long-term health is non-controversial. However, for decades, food and nutrition discussions have often been highly medicalized. Given the significant impact of poor nutrition on health, broader discussions about food should be integrated into routine patient history taking. We advocate for an expansion of the current, standard approach to patient history taking in order to include questions regarding patients' 'foodlife' (total relationship to food) as a screening and baseline assessment tool for referrals. We propose that healthcare providers: (1) routinely engage with patients about their relationship to food, and (2) recognize that such dialogues extend beyond nutrition and lifestyle questions. Mirroring other recent revisions to medical history taking-such as exploring biopsychosocial risks-questions about food relationships and motivators of eating may be essential for optimal patient assessment and referrals. We draw on the novel tools of 'foodlife' ethnography (developed by co-author ethnographer J.J.L., and further refined in collaboration with the co-authors who contributed their clinical experiences as a former primary care physician (D.M.E.), registered dietitian (J.W.M.), and diabetologist (H.Z.)) to model a set of baseline questions for inclusion in routine clinical settings. Importantly, this broader cultural approach seeks to augment and enhance current food intake discussions used by registered dietitian nutritionists, endocrinologists, internists, and medical primary care providers for better baseline assessments and referrals. By bringing the significance of food into the domain of routine medical interviewing practices by a range of health professionals, we theorize that this approach can set a strong foundation of trust between patients and healthcare professionals, underscoring food's vital role in patient-centered care.

U.S. food policy to address diet-related chronic disease

Poor diet is the leading cause of mortality in the U.S. due to the direct relationship with diet-related chronic diseases, disproportionally affects underserved communities, and exacerbates health disparities. Evidence-based policy solutions are greatly needed to foster an equitable and climate-smart food system that improves health, nutrition and reduces chronic disease healthcare costs. To directly address epidemic levels of U.S. diet-related chronic diseases and nutritional health disparities, we conducted a policy analysis, prioritized policy options and implementation strategies, and issued final recommendations for bipartisan consideration in the 2023-24 Farm Bill Reauthorization. Actional recommendations include: sugar-sweetened beverage taxation, Supplemental Nutrition Assistance Program (SNAP) fruit and vegetable subsidy expansion, replacement of ultra-processed foods (UPF) with sustainable, diverse, climate-smart agriculture and food purchasing options, and implementing "food is medicine."

Food is medicine intervention shows promise for engaging patients attending a safety-net hospital in the Southeast United States

Public health organizations, including the Academy of Nutrition and Dietetics and the American Hospital Association, recognize the importance of achieving food and nutrition security to improve health outcomes, reduce healthcare costs, and advance health equity. In response, federal, state, and private agencies are increasingly seeking to fund healthcare-based interventions to address food insecurity among patients. Simultaneously, nutrition-based interventions targeting chronic diseases have grown across the United States as part of the broader "Food is Medicine" movement. Few studies have examined the successes, challenges, and limitations of such efforts. As Food is Medicine programs continue to expand, identifying common approaches, metrics, and outcomes will be imperative for ensuring program success, replicability, and sustainability. Beginning in 2020, the Food as Medicine (FAM) program, a multipronged, collaborative intervention at Grady Health System has sought to combat food insecurity and improve patient health by leveraging community resources, expertise, and existing partnerships. Using this program as a case study, we (1) outline the collaborative development of the FAM program; (2) describe and characterize patient engagement in the initial 2 years; and (3) summarize strengths and lessons learned for future hospital-based food and nutrition programming. As this case study illustrates, the Food as Medicine program provides a novel model for building health equity through food within healthcare organizations.

Food is Medicine National Summit: Transforming Health Care

Food is Medicine (FIM) interventions reflect the critical links between food security, nutrition security, health, and health equity, integrated into health care delivery. They comprise programs that provide nutritionally tailored food, free of charge or at a discount, to support disease management, disease prevention, or optimal health, linked to the health care system as part of a patient's treatment plan. Such programs often prioritize health equity. On 26-27 April, 2023, Tufts University's Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy and Food & Nutrition Innovation Institute held a 2-day National Food is Medicine Summit with leaders, practitioners, and individuals with diverse lived experiences in health care, research, government, advocacy, philanthropy, and the private sector to identify challenges and opportunities to sustainably incorporate FIM services into the health care system and at scale. This report of a meeting describes key themes of the Summit, based on presentations and discussions on momentum around FIM, incorporating FIM in health care, tradeoffs and unintended consequences of various FIM models, scaling of programs, financing and payment mechanisms, educating and engaging the health care workforce, and federal and state government actions and opportunities on FIM. Speakers highlighted examples of recent public and private sector actions on FIM and innovative cross-sector partnerships, including state Medicaid waivers, academic and philanthropic research initiatives, health care system screenings and interventions, and collaborations including community-based organizations and/or entities outside of the food and health care sectors. Challenges and opportunities to broader implementation and scaling of FIM programs identified include incorporating FIM into health care business models, educating the health care workforce, and sustainably scaling FIM programs while leveraging the local connections of community-based organizations. This meeting report highlights recent advances, best practices, challenges, and opportunities discussed at the National Summit to inform future actions on FIM.

Planting Seeds for Food Is Medicine: Pre-Implementation Planning Methods and Formative Evaluation Findings From a Multi-Clinic Initiative in the Midwest

Food is medicine (FIM) initiatives are an emerging strategy for addressing nutrition-related health disparities increasingly endorsed by providers, payers, and policymakers. However, food insecurity screening protocols and oversight of medically-tailored food assistance programs are novel for many healthcare settings. Here, we describe the pre-implementation planning processes used to successfully engage federally-qualified health centers (FQHCs) across Kansas to develop new FIM initiatives. A Kansas-based philanthropic foundation facilitated pre-implementation planning for FQHCs over 17 months across 3 stages: 1) Community inquiry, 2) FIM learning event with invitation for FQHC attendees to request pre-implementation funding, and 3) Pre-implementation planning workshops and application assignments for FQHC grantees to develop a FIM implementation grant proposal. We evaluated satisfaction and perceived utility of these pre-implementation planning activities via post-workshop surveys and qualitative comparisons of FIM design components from pre-implementation and implementation grant applications. All 7 FQHCs attending the learning event applied for and were awarded pre-implementation planning grants; 6 submitted an implementation grant application following workshop completion. FQHCs rated pre-implementation support activities favorably; however, most clinics cited limited staff as a barrier to effective planning. As compared to pre-implementation planning grant proposals, all FQHCs elected to narrow their priority population to people with pre-diabetes or diabetes with better articulation of evidence-based nutrition prescriptions and intervention models in their final program designs. In the midst of a nationwide FIM groundswell, we recommend that funders, clinic stakeholders, and evaluators work together to devise and financially support appropriate pre-implementation planning activities prior to launching new FIM initiatives.

Feasibility of self-investment in a medically tailored meals program by a large health enterprise: Cleveland Clinic experience

Background: Medically tailored meals (MTMs) are personalized meals designed to meet the therapeutic needs of patients with chronic diseases. Most MTM programs rely on philanthropic support, and the optimal parameters for these programs are not well-defined. Aim: To assess the feasibility of an MTM program developed by a major healthcare institution using internal investments and an online platform for meal ordering. Methods: Single-arm prospective cohort feasibility MTM project implemented between August 2021 and June 2022. Each participant received 14 frozen meals per week over 3 months via a courier system. Participants answered several questionnaires and healthcare utilization was abstracted from electronic medical records up to 6 months post-intervention. Results: Sixty participants were enrolled. Emergency department (ED) visits and inpatient days significantly decreased in the 180 days post-intervention compared to the 180 days pre-intervention (ED visits: 1.2 vs 1.7, P = 0.005; inpatient days: 3.2 vs 5.1, P = 0.02). Participants saved an average of $12,046 in healthcare costs. Despite challenges with implementation, including upfront costs and sustainability, client and service outcomes were highly favorable. Patients were overwhelmingly satisfied with the program, although there was no quantitative improvement in global mental health (GMH) or global physical health (GPH) scores. Conclusion: MTM programs run by healthcare institutions can enhance patient satisfaction, reduce hospital visits, and lower healthcare costs, particularly for vulnerable populations. Providing healthy, frozen meals over an extended period is feasible, though it requires significant initial investment. Large healthcare institutions should consider implementing such programs to prioritize primary prevention in the US healthcare system.

Gaining stakeholder perspectives to shape a produce prescription program to improve maternal and birth outcomes: a qualitative study

Introduction

Nutrition during pregnancy significantly impacts maternal and birth outcomes. A key factor contributing to the rise in adverse maternal and birth outcomes is poor nutrition. Produce prescription programs have the potential to address pregnancy-related adverse outcomes such as hypertensive disorders and gestational diabetes, but scientific evidence is limited.

Purpose

To conduct qualitative interviews to gain an in-depth understanding of how, why, and in what context should produce prescriptions be implemented to best meet the needs of pregnant women in a clinical setting.

Methods

We conducted interviews with 11 patients with low incomes and/or experiencing food insecurity and 11 clinic staff from a major metropolitan OB/GYN clinic. Interview questions were designed to understand attitudes toward participating in or helping implement a produce prescription program. We analyzed the data using a deductive qualitative content analysis approach.

Results

Both patients and clinic staff perceived many benefits to this type of program, including easing financial strain, removing barriers to access, and addressing nutrition security during pregnancy. Both groups described a need to consider participants' autonomy in the program design. Patients also perceived some drawbacks to the home delivery aspect, such as limited participation by patients due to unstable housing. Staff expressed some concerns about the staff time needed to implement this type of program.

Conclusion

There was strong support for produce prescription programs for this population; however, results indicate that they may best meet needs if patient autonomy and delivery-related barriers are considered in the design. Designating screening and enrollment tasks for ancillary staff may facilitate implementation in clinics.

Examining Food Security, Fruit and Vegetable Intake, and Cardiovascular Disease Risk Outcomes of Produce Prescription (PPR) Programs: A Systematic Review

OBJECTIVE

Outcomes from produce prescription (PPR) programs, an exemplar of a Food is Medicine intervention, have not been synthesized. The objective of this study was to conduct a systematic review to examine the impact of PPR programs on food security, fruit and vegetable (FV) intake, and/or cardiovascular risk factors (HbA1c, blood pressure, and blood lipids).

DESIGN

Searches were conducted across three databases (PubMed, CINAHL, and Web of Science). Eligible studies were published between August 2012 and April 2023, conducted in the US in child/family, or adult populations, written in English and had a PPR program as an exposure.

OUTCOMES VARIABLES MEASURED

Food security, FV intake, and/or cardiovascular risk factors.

RESULTS

Twenty studies ranging from a duration of between 6 weeks to 24 months were included. Of the 5 studies (3 in child/family and 4 in adult populations) that analyzed changes in food security status, all reported significant (P < 0.05) improvements after the PPR program. Approximately half of the included studies found significant (P < 0.05) increases in fruit, vegetable, and/or FV intake. Only studies in adult populations included cardiovascular risk factor outcomes. In these studies, mixed findings were reported; however, there were significant (P < 0.05) improvements in HbA1c when PPR programs enrolled individuals with type 2 diabetes.

CONCLUSIONS AND IMPLICATIONS

PPR programs provide an opportunity to improve food security in child/family, and adult populations. Evidence to support whether PPR programs increase FV intake and improve cardiovascular disease risk factors outside of HbA1c in adult populations with high HbA1c upon enrollment is less known.

Engagement in a pilot produce prescription program in rural and urban counties in the Southeast United States

Introduction

In the United States, over one in every ten households experiences food insecurity. Food insecurity is associated with often co-occurring adverse health consequences, including risk for obesity, type 2 diabetes, and hypertension. Within the "Food is Medicine" intervention space, Produce Prescription Programs (PRx) seek to alleviate food insecurity and improve diet and health outcomes by leveraging access to produce through healthcare organizations. Though these programs are burgeoning across the United States, research surrounding their implementation and outreach is limited.

Methods

This study evaluates the implementation, reach, engagement, and retention of a PRx program piloted in two regions of Georgia (US) from 2020 to 2022. The study included 170 people living with one or more cardiometabolic conditions recruited from clinical sites in metropolitan and rural areas. The program provided pre-packaged produce boxes and nutrition education over six months. We examine participants' baseline demographics, food security status, dietary patterns, and loss to follow-up across contexts (metropolitan and rural). We employ regression analyses and model comparison approaches to identify the strongest predictors of loss to follow-up during the pilot period.

Results

In the pilot period of this program, 170 participants enrolled across rural and metropolitan sites. Of these, 100 individuals (59%) remained engaged for the six-month program. While many individuals met the target criteria of living with or at-risk of food insecurity, not all lived with low or very low food security. Metropolitan participants, males, and those with children in the household had significantly higher odds of loss to follow-up compared to rural participants, females, and those without children in the household. No other significant demographic or household differences were observed.

Discussion

This study demonstrates the potential of PRx programs to enhance food and nutrition security and cardiometabolic health in metropolitan and rural clinical settings. Future research should focus on addressing barriers to engagement and expanding the reach, impact, and sustainability of PRx programs across diverse contexts.
