Healthy Food Rx programs, also known as "Food is Medicine" initiatives, are gaining recognition as effective strategies to combat food insecurity and diet-related chronic diseases. These programs aim to improve access to nutritious foods, particularly fruits and vegetables, and provide education and support to promote healthier eating habits.
Understanding the Core Components
Healthy Food Rx programs often incorporate two key components:
- Produce Prescription Programs: Healthcare providers "prescribe" fruits and vegetables to patients who meet specific criteria, such as those with diet-related health conditions or food insecurity. These prescriptions can be redeemed at various food sites.
- Fruit and Vegetable Voucher Incentive Programs: These programs provide vouchers, coupons, or cash incentives to consumers, encouraging them to purchase more fruits and vegetables at participating locations.
While these programs can operate independently, many successful initiatives integrate both components to maximize their impact.
Addressing Food and Nutrition Security
Food and nutrition security is defined as having consistent access to sufficient, high-quality food to maintain health and prevent hunger. A significant barrier to achieving this is the limited accessibility of fresh fruits and vegetables, especially in low-income communities. Healthy Food Rx programs address this challenge by:
- Improving Access: By providing financial incentives and produce prescriptions, these programs make fruits and vegetables more affordable and accessible to individuals who may otherwise struggle to obtain them.
- Supporting Local Growers: Programs that prioritize fresh produce can also benefit local farmers by connecting them with community members and strengthening the local food system.
- Promoting Variety: While fresh produce is emphasized, programs also recognize the value of canned, dried, and frozen fruits and vegetables, which are often more affordable, widely available, and have a longer shelf life. It's crucial to encourage options without unhealthy additives like added sugars, sodium, and unhealthy fats.
Key Elements of Successful Programs
Several factors contribute to the success of Healthy Food Rx programs:

- Community Input: Involving community members in the planning and implementation process ensures that programs are culturally relevant and meet the specific needs of the target population. This includes selecting appropriate food sites that can stock high-quality, affordable, and culturally preferred produce.
- Integration with Healthcare: Incorporating medical coding for screening and diagnosis of food insecurity, as well as payment mechanisms for these programs, can help to integrate them into the healthcare system and ensure sustainability.
- Nutrition Education: Providing educational resources, such as recipes and cooking demonstrations, can help participants learn how to prepare healthy meals and make informed food choices.
- Wraparound Support: Connecting participants with additional resources, such as SNAP application assistance and referrals to other social services, can address the underlying social determinants of health that contribute to food insecurity.
Real-World Examples and Outcomes
Several Healthy Food Rx programs have demonstrated promising results:
- Abbott's Healthy Food Rx Program: This program in Stockton, California, has reached over 1,700 residents and aims to improve diabetes outcomes by addressing social and economic barriers to good health. Participants receive recipe-based food boxes filled with nutrient-dense ingredients. A clinical trial assessing the impact of Abbott's Healthy Food Rx demonstrated that participants reported significantly increased vegetable consumption compared to the control group (0.37 vs. 0.03 increased servings per day; p = 0.007), and increased fruit consumption compared to control group (0.3 vs. 0.2 increased servings per day, p = 0.232). Healthy Food Rx participants reported significantly greater improvements in self-reported physical health status over six months (from 38% to 63%, p < 0.001), compared to the control group (from 47% to 50%, p=0.453; between group p<0.001). A1C levels significantly improved for both Healthy Food Rx participants and the control group. A1C is a test that reflects average glucose levels for the past three months; levels decreased by 0.7% and 1.2%, in the intervention group and control group, respectively. Both values exceeded the widely accepted 0.5% benchmark that is considered a clinically significant change and is associated with improved health outcomes in people with diabetes.
- FOODRx Program by Second Harvest Heartland: This program partners with healthcare providers and insurers to provide food-insecure patients with medically tailored groceries and nutrition education. Independent research studies have shown that the FOODRx program delivers the following results: Partners saw a 44% decrease in total healthcare claims, with an average cost per claim dropping 15.5%. 17% drop in overall ER visits; 60% fewer ER visits among those using support services. 25% of participants achieved HgbA1c <7.5% with significant reductions in fasting glucose and HgbA1c. ≥ 90% of FOODRx participants reported the food helped them feel better and worry less about their supply of food. Participants reported reduced instances of skipping meals and choosing between food and medicine, with a 24% reduction in food insecurity prevalence.
These examples highlight the potential of Healthy Food Rx programs to improve dietary behaviors, health outcomes, and overall well-being.
The Role of Food Sites
Food sites, where participants can purchase or obtain fruits and vegetables, are crucial components of these programs. A variety of food sites may be part of these programs, and site selection should include community input. It's essential to consider the site's ability to stock high-quality, affordable, and culturally preferred produce. These sites can include:
- Food pantries
- Farmers markets
- Brick-and-mortar grocery stores
- Online grocery stores
- Mobile markets
Addressing Chronic Disease Through Nutrition
The United States faces a chronic disease epidemic, often linked to systemic barriers to food access and social drivers of health, such as food insecurity. Food insecurity increases the risk of developing chronic diseases. Individuals facing hunger are:
- 2-3 times more likely to have type 2 diabetes
- 1. 6 times more likely to have heart disease
- 2. 2 times more likely to have high blood pressure
Healthy Food Rx programs aim to break this cycle by connecting patients to healthier food, reducing healthcare costs, and improving health outcomes and patient well-being.

Program Components
- Food Prescription: Monthly home-delivered boxes of shelf-stable foods, carefully curated by a registered dietitian. These boxes contain either 13 or 25 meals per box that are proportionally balanced and designed to supplement the diet. Original or Vegetarian versions, featuring culturally relevant ingredients from 5 different cuisines. The program typically lasts for six months, with the option to extend.
- Nutrition Education: Educational materials and recipes to help manage conditions and encourage behavioral changes for a healthier lifestyle. Monthly touchpoints, including coaching calls conducted by program advisors, provide supportive engagement and reinforce long-term behavior change.
- Wraparound Food Access Support: Ongoing coordination of care related to SNAP application assistance, Commodity Supplemental Food Program (senior food box) enrollment, other federal benefits, food resource access, and referrals to additional non-food supports. Care Centers offer food resource navigators who speak multiple languages and work with interpreters to support additional languages.
- Partner Integration and Reporting: Monthly reporting and Key Performance Indicator (KPI) tracking with HIPAA compliance. Partner employee engagement, e.g., with case workers or clinic staff. Evaluate patient outcomes to measure the feasibility and effectiveness of nutrition interventions
