Customized meal delivery may help reduce blood pressure and blood sugar

Meals delivered to the home and tailored to medical needs were associated with improved blood pressure, blood sugar and overall diet quality in a small study.

Researchers also found that the benefits seemed to hold even when the number of meals was reduced over time, as long as education and support continued.

A team from Columbia University tracked 110 adults in New York City who had both type 2 diabetes and high blood pressure. Over eight months, the program paired prepared meals with nutrition counseling, cooking demonstrations and ingredients intended to support healthier eating at home.

The findings are set to be presented at the American Heart Association’s Scientific Sessions 2026. Because the study is preliminary, it compared two versions of the program rather than measuring meal delivery against no food support at all.

The purpose of medically tailored meals is to make appropriate food easier to access, rather than relying only on dietary advice. That approach may matter most when cost, shopping, cooking or limited access to nutritious food makes day-to-day management difficult.

Participants were about 63 years old on average, and most were women. They came from neighborhoods with high rates of chronic illness and premature death, including many Black and Hispanic residents.

One group received 10 prepared meals a week for the full program. The other started at the same level, then gradually dropped to five meals a week in the final month after the first three months.

Both groups also got dietitian counseling and an interactive heart-health program. Cooking demonstrations, fresh produce, seasonings and recipes were adapted to cultural preferences and aimed at helping people prepare more meals themselves.

By the end of eight months, diet quality scores had improved in both groups. Participants also reported better food security, indicating that the program may have eased a practical obstacle as well as changed what they ate.

Average HbA1c, a blood marker that reflects blood sugar over recent months, fell by about half a percentage point. Both the top and bottom blood pressure readings dropped by roughly four points.

The similar outcomes in both groups suggest that a gradual reduction in meal deliveries could be workable if other support remains in place. Still, the study did not identify the ideal number of meals or fully compare costs and benefits.

It also could not isolate the effect of the delivered food from counseling, education or other changes that happened during the program. Since the research involved only one site and a relatively small group, larger studies will be needed to see how well the model works in other settings.

Overall, the results point to a practical direction for studying food as part of health care. The next question is whether such programs can deliver lasting benefits while staying affordable and accessible to the people who need them.
