Highlights
- By increasing fruit and vegetable consumption, a recent study highlights the potential of “produce prescriptions” to improve heart health.
- Participants in various low-income neighborhoods received food vouchers to purchase more produce, leading to significant improvements in their health.
- Adults who participated in the programs consumed about 30% more produce per day, while children ate around 7% more.
- The positive effects of increased produce consumption on blood pressure were roughly half that of commonly prescribed medications.
- The study emphasizes the need for innovative approaches to address diet-related illnesses, especially in the context of chronic health conditions.
- Further research, including randomized trials, is necessary to establish a concrete link between diet changes and improved health outcomes.
- The Rockefeller Foundation and the American Heart Association are collaborating on a comprehensive initiative to examine the long-term impact of “prescribing food.”
- Addressing diet-related illnesses through innovative interventions could significantly contribute to improving public health outcomes.
Fruit and Vegetable
In an effort to address the inadequate consumption of fruit and vegetable among Americans, a recent study suggests that “produce prescriptions” could play a pivotal role in improving heart health. These programs involve healthcare providers “prescribing” fruits and vegetables to patients as part of their treatment plans, leading to increased consumption, weight loss, and significant reductions in blood pressure.
State Participation
The study, believed to be the largest of its kind, focused on 3,881 participants from low-income neighborhoods across a dozen states in the U.S. These individuals received food vouchers valued at $15 to $300 per month through nine different programs aimed at promoting the purchase of more fruits and vegetables from farmers markets and grocery stores.

Produce Consumption
Before and after participating in these programs, researchers monitored participants’ produce consumption, cardiovascular health, levels of food insecurity, and self-reported health status. Results indicated that adults who took part in the programs consumed approximately 30% more produce per day.
Adult participants reported consuming an additional average of 0.85 cups of fruits and vegetables daily, while children consumed 0.26 cups more – an increase of about 7%. These findings are significant considering that most Americans fall short of consuming the recommended amount of fruits and vegetables daily, as stated by the Centers for Disease Control and Prevention.
Dr. Kurt Hager, the lead author of the study and an instructor at UMass Chan Medical School, highlighted the urgent need for improved nutrition among patients, especially those with chronic health conditions.
“Physicians, historically, have had very few tools to improve the nutrition of their patients besides from some limited access to nutrition counseling,” he noted.
Interestingly, the effect of increased fruit and vegetable consumption on blood pressure was found to be roughly half that of commonly prescribed medications. This suggests that a simple change in diet could potentially yield significant benefits for heart health.
Heart Disease or Type 2 Diabetes
The participants in these programs were either at risk of developing heart disease or Type 2 diabetes, and they were recruited due to food insecurity or from low-income neighborhoods. Each program spanned an average of six months and took place between 2014 and 2020.
Produce Prescription Programs
Produce prescription programs have gained traction in recent years, especially during the COVID-19 pandemic, as the significance of diet-related illnesses became more apparent. The pandemic underscored the need for effective interventions to address chronic health conditions, particularly those related to heart disease and diabetes.
Despite the promising findings, Dr. Hager emphasized the need for further research to establish a concrete link between increased fruit and vegetable consumption and improved health outcomes. The study’s limitations, such as the lack of a control group and a retrospective approach, warrant cautious interpretation of the results.
It remains unclear whether the health improvements were solely attributed to dietary changes or if they were influenced by addressing food insecurity within households. This distinction is crucial as a substantial percentage of the participating households experienced food insecurity.
Researchers and Health Organizations
Moving forward, researchers and health organizations are working to conduct more extensive studies, such as randomized trials, to validate the effectiveness of produce prescription programs in enhancing heart health. With the increasing emphasis on preventative healthcare, the potential benefits of “prescribing food” to manage and reduce the risk of chronic conditions are being recognized.
The Rockefeller Foundation has initiated a substantial partnership with the American Heart Association to delve deeper into the long-term impact of these programs. As healthcare costs continue to rise and chronic conditions remain a significant concern, addressing diet-related illnesses through innovative interventions could be a crucial step toward improving public health outcomes.
