Food-as-Medicine: Can Healthy Food Delivery Improve Heart Failure Recovery?

For patients recovering from heart failure, the transition from hospital to home is a critical window for recovery. While dietary counseling is a standard part of care, actually accessing and preparing heart-healthy meals can be a significant barrier. A recent clinical trial, known as FOOD-HF, explored whether providing direct food supplementation—either through prepared meals or fresh produce—could improve outcomes for these patients.

Understanding the FOOD-HF Trial

The FOOD-HF trial, published in JAMA Cardiology, was led by researchers from UT Southwestern Medical Center. The study aimed to determine if “food-as-medicine” interventions are feasible and effective for patients recently hospitalized for acute heart failure (HF).

The study randomized 150 patients at Parkland Hospital and UT Southwestern Medical Center in Dallas into three distinct groups for a 90-day period:

• Medically Tailored Meals (MTM): Patients received 14 low-sodium, refrigerated, full prepared meals per week, designed in consultation with registered dietitians.
• Fresh Produce Boxes: Patients received boxes containing fresh fruits, vegetables, whole grains, dairy, eggs, olive oil, and pantry staples, accompanied by healthy recipes.
• Usual Care: Patients received standardized dietary counseling.

The “Conditional” vs. “Unconditional” Approach

Researchers added a layer of complexity by dividing the food-receiving groups into two subgroups to test the impact of health behaviors:

• Conditional Group: Food was provided only if the patient picked up their medications from the pharmacy and attended follow-up clinic appointments.
• Unconditional Group: Food was provided regardless of medication pickup or appointment attendance.

Key Findings: Quality of Life vs. Hospitalization

The results of the trial provide a nuanced look at how food interventions impact recovery. While the study did not find a significant reduction in short-term heart failure hospitalizations or emergency department visits, it did highlight meaningful improvements in other areas.

Clinical Outcomes

Over the three-month period, there were 32 HF-related events (hospitalizations or ER visits). The risk remained similar between those receiving food supplementation and those receiving usual care, with an adjusted risk ratio of 1.09 (p=0.83).

Patient Well-being and Feasibility

Despite the lack of impact on readmission rates, the food-as-medicine strategies were found to be both feasible and well-accepted by patients. Most importantly, a hierarchical composite measure revealed a clinically meaningful improvement in quality of life for those receiving food supplementation compared to usual care.

Key Takeaways

Frequently Asked Questions

What are medically tailored meals (MTM)?

Medically tailored meals are prepared foods specifically designed by registered dietitians to meet the nutritional needs of a patient with a specific medical condition—in this case, low-sodium meals for heart failure recovery.

Did the produce boxes work as well as the prepared meals?

The trial evaluated both strategies as “food-as-medicine” interventions. While both contributed to the overall findings regarding feasibility and quality of life, the primary goal was to assess the general effect of food supplementation over usual care.

The Path Forward

The FOOD-HF trial suggests that while food alone may not prevent immediate hospital readmission, it significantly enhances the daily lives of patients recovering from heart failure. By addressing food insecurity and nutritional gaps, healthcare providers can improve patient well-being, providing a critical foundation for long-term health management.
