The health of people with diabetes, hypertension and obesity improved when they could get free fruits and vegetables with a prescription from their doctors and other health professionals.
The improvements we saw in clinical outcomes could have a meaningful impact on overall health. For example, systolic blood pressure, or blood pressure during heartbeats, decreased more than 8 millimeters of mercury, or mm Hg, while diastolic blood pressure, or blood pressure between heartbeats, decreased nearly 5 mm Hg. For context, this is about half the drop gained through medications that lower blood pressure.
Many U.S. health care providers have been experimenting with "food is medicine" programs, which provide free, healthy food to patients — sometimes for a year or more.
This is the largest analysis to date of produce prescription programs, which are one variety of these efforts. They let patients with diet-related illnesses get apples, broccoli, berries, cucumbers and other kinds of fruits and vegetables for free. In Los Angeles, Boise, Houston, Minneapolis and other places where the programs we studied were located, participants selected the produce of their choice at grocery stores or farmers markets using electronic cards or vouchers. They typically received about US$65 per month for four to 10 months.
We pooled data from 22 U.S. produce prescription locations operated by Wholesome Wave, a nonprofit that promotes access to affordable, healthy food. None of the pilots had previously been evaluated. All 4,000 participants either had, or were at risk for, poor cardiometabolic health and were recruited from clinics serving low-income neighborhoods.
Participants in these programs ate more fruits and vegetables. They were also one-third less likely to experience food insecurity — not having enough food to meet basic needs and lead a healthy life.

What's next
We are evaluating "food is medicine" pilots funded by the Flexible Services Program in Massachusetts' Medicaid program. We are also running a large, randomized controlled trial, in which one group of patients with cancer will get free home-delivered meals and another will receive standard care.
The Research Brief is a short take on interesting academic work.
