Medically tailored home meals linked to better blood pressure and diabetes control

Meals delivered to the home and adapted to medical needs may help people living with diabetes and high blood pressure improve key health measures. In an eight-month program, participants saw better diet quality, easier access to nutritious food, and small declines in blood pressure and blood sugar.

People who later received fewer meals in the program showed gains similar to those who continued getting the full meal package. Both groups also took part in nutrition counseling and received practical help for healthier eating at home.

The findings point to the possibility that food support could play a more sustainable role in chronic disease care. Still, the results are preliminary and do not show that lowering meal deliveries will suit everyone or that meals can take the place of medication.

The study was presented for the American Heart Association’s Scientific Sessions 2026. It was led by Nour Makarem of Columbia University’s Mailman School of Public Health and included 110 adults in New York City who had both type 2 diabetes and hypertension.

The average participant was 63 years old, and roughly two-thirds were women. Researchers recruited them from neighborhoods with high rates of chronic illness and early death, making access to food a central part of the health picture.

One group received 10 medically tailored meals each week for eight months. The other group received the same number for three months, then saw their deliveries reduced by one meal per week each month until they were getting five meals weekly.

Another strategy being explored alongside dietary support is continuous glucose monitoring for type 2 diabetes management.

In both groups, participants met with a dietitian and received education focused on heart health. Cooking demonstrations, produce, seasonings and other ingredients were also provided, underscoring that the program went beyond simply dropping off prepared meals.

By the end of the eight-month period, diet quality had improved in both groups, including closer adherence to a Mediterranean-style eating pattern. Participants were also more likely to report improved food security, meaning more dependable access to enough food.

HbA1c, a key blood sugar marker, dropped by about half a percentage point. Both systolic and diastolic blood pressure fell by around four millimeters of mercury, showing measurable health improvements alongside changes in diet.

The similar results seen in both groups suggest that education and support for home cooking may help preserve benefits as deliveries taper off. However, the study did not compare the program with a similar group that received no meal support, which limits what can be said about cause and effect.

It was also conducted in a single city, and the findings have not yet appeared in a full peer-reviewed journal report. Larger studies will be needed to test different populations, follow outcomes for longer, and determine whether a reduced-delivery model is truly cost-effective.

In practical terms, the approach could help address food access while also teaching skills people can keep using. If future research confirms the results, such nutrition support could become more available for people managing multiple chronic conditions and be folded into broader care plans.
