Revolutionizing Cardiovascular Health : How Produce Prescriptions Can Make a Difference

Emerging research has highlighted the potential of produce prescriptions in mitigating risk factors associated with cardiovascular disease, while also promoting greater intake of fruits and vegetables.⁽¹⁾ These findings suggest that such prescriptions may not only contribute to reduced food insecurity but also lead to an enhanced self-reported health status among participants. Participants deemed at an elevated risk for heart disease, engaging in “produce prescription” initiatives for an average duration of six months, notably increased their consumption of fruits and vegetables. These findings were published in the peer-reviewed American Heart Association journal, Circulation recently.

While the study sheds valuable light on the benefits of produce prescriptions, experts and researchers acknowledge certain limitations within this approach. It is important to recognize that while produce prescriptions hold promise, they may not be a one-size-fits-all solution.

So what exactly are produce prescriptions and can they really help reduce the risk of cardiovascular disease? Let’s have a look.

In addressing health disparities prevalent among low-income households, ‘produce prescriptions’ have today emerged as a transformative solution. These prescriptions empower doctors to recommend subsidized fruits and vegetables, effectively bridging the gap in diet-related chronic diseases.⁽²⁾

While the concept of medically tailored meals and produce prescriptions may appear innovative, it is not entirely new. In a study led by Hager in October 2022, medically tailored meals were found to potentially reduce hospitalizations by 1.6 million, resulting in a net cost savings of $13.6 billion annually.⁽³⁾ These meals, distinct from money-for-produce prescriptions, are typically fully prepared, tailored to an individual’s health requirements, and delivered to their homes. For instance, meals could be customized to limit carbohydrates for those with diabetes or restrict sodium for individuals with high blood pressure.

Despite their differences, these initiatives fall under the same overarching concept, collectively referred to as medically sourced food. The underlying principle remains consistent: they are financially supported in some manner and prescribed by healthcare providers.

Furthermore, a separate 2022 study proposed that integrating produce prescriptions into the healthcare system could lead to improved health outcomes for individuals with low socioeconomic status.⁽⁴⁾ Like the current study, researchers emphasized the potential of a “food-as-medicine” approach, leveraging produce prescriptions to address health disparities.

All three studies underscore a common theme: increased access to fruits and vegetables has demonstrated positive health outcomes for both children and adults, including enhanced blood glucose control for individuals with a history of diabetes.

Remember that a higher intake of fruits and vegetables is directly related to improved heart health. Doctors have emphasized that diets high in sodium and carbohydrates contribute significantly to prevalent cardiovascular risk factors like hypertension and type 2 diabetes, as well as conditions like heart failure. Given that cardiovascular disease ranks as the primary cause of mortality in the United States, even slight dietary enhancements can yield significant impacts.^(5,6,7)

In a groundbreaking study conducted in collaboration with the national nonprofit Wholesome Wave, researchers set out to explore the impact of produce prescriptions on clinical health outcomes. Focusing on 3,881 participants at elevated risk for heart disease across 12 states, the study encompassed 2,064 adults (ages 18 and older) and 1,817 children (ages 2 to 17). Participants received a median monthly financial incentive of $63, earmarked for purchasing produce from local stores and farmers’ markets, supplemented by educational nutrition classes.⁽⁸⁾

The program duration spanned from 4 to 10 months, with an average of 6 months. Following program completion, participants provided feedback through questionnaires regarding their produce consumption, food security, and overall health status. They also underwent standard tests for blood pressure, weight, height, and hemoglobin A1c (HbA1c), a marker of average blood glucose levels over a 3 to 4 month period.

While lacking a control group, the researchers conducted a comparative analysis of participants’ outcomes before and after the produce prescription program.

Key findings from the data analysis revealed:

• Adults demonstrated a notable increase in daily produce intake, up by almost one cup (0.85 cups), while children saw an improvement of over a quarter of a cup daily (0.26 cups daily).
• Food insecurity rates experienced a significant reduction, decreasing by one-third among both adult and pediatric participants.
• Self-reported health status witnessed a substantial enhancement, with a two-thirds improvement in adults and more than a two-fold increase in children.
• Adult participants with initial HbA1c levels of 6.5% or higher experienced a decrease in blood sugar levels.
• Participants with high blood pressure at the beginning of the study showed a reduction in systolic and diastolic blood pressure.
• While adults experienced a slight decrease in BMI, no significant change was observed in children.

This modeling study provides evidence that produce prescription programs may increase consumption of nutritious fruits and vegetables and reduce food insecurity.

While the study on produce prescriptions offers valuable insights, it is important to acknowledge the study’s inherent limitations. One notable constraint lies in the absence of a control group, rendering it a non-randomized controlled trial (RCT). The absence of randomization is significant, as it could potentially introduce confounding variables and hinder a clear understanding of whether the observed effects are directly attributed to the prescription or influenced by other underlying factors.

The importance of randomization in research is that it helps mitigate disparities between individuals who naturally gravitate towards healthier food choices and those who do not. The absence of this element leaves a degree of uncertainty surrounding the true impact of produce prescriptions.

While acknowledging the study’s contributions, it is important to note that the study design is also a limiting factor. This should further serve as a catalyst for further research in the field. Large-scale, randomized controlled trials are deemed crucial for substantiating these findings, and they may ultimately play a pivotal role in the widespread integration of produce prescriptions into U.S. healthcare practices.

Another aspect to consider is the reliance on self-reported data, which may introduce subjective elements into the analysis. The surveys used in the study are inherently subjective, with the only objective measures being those obtained during clinical assessments, such as HbA1C levels, blood pressure readings, and BMI.

Moreover, the study’s failure to address the practicality and sustainability of long-term implementation of produce prescription programs also needs to be taken into account. Vital questions surrounding the cost-effectiveness and feasibility of scaling up these initiatives to a national level, as well as their adaptability within diverse cultural contexts, remain unexplored.

Accessing produce prescriptions may not yet be widespread, but there are avenues individuals can explore to benefit from this innovative healthcare approach.

Medicare Advantage is beginning to cover fresh foods and medically-tailored meals. Additionally, certain states, like California, offer waivers that permit individuals with specific conditions, such as type 2 diabetes, to utilize Medicaid funds for purchasing food within a specified timeframe.

For now, obtaining a produce prescription follows a similar process to acquiring more conventional medications. Similarly, remember that a crucial component of Food Is Medicine programs is a physician’s prescription. Individuals are encouraged to engage in a discussion with their healthcare provider to explore their eligibility for these programs. Furthermore, they may want to inquire with their health insurance provider to determine whether food resources are accessible.

The study highlights the potential benefits of produce prescriptions in improving fruit and vegetable intake and reducing risk factors associated with heart disease. It also addressed food insecurity concerns, particularly among participants facing economic challenges. While the study’s design had limitations, it underscored the crucial role of diet in overall health. Individuals interested in food prescriptions should consult their healthcare provider and explore availability through their insurance provider. This research marks a significant step towards utilizing nutrition as a powerful tool for enhanced heart health and overall well-being.
