Food as medicine: can cooking classes and grocery delivery lower blood pressure?
NCT ID NCT07332741
First seen Jun 25, 2026 · Last updated Jul 10, 2026 · Updated 2 times
Summary
This study tests whether a 12-week program of home-delivered DASH-diet groceries and cooking classes can help adults with high blood pressure and obesity lower their blood pressure and lose weight. 150 participants will be randomly assigned to either the food program or usual care. The study also looks at whether such a program could be used widely in the community.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- DASH-diet food delivery and culinary skill-building sessions
- What this could lead to
- If it works, this could point toward a practical, community-based program to help people with high blood pressure and obesity eat healthier and improve their health.
- What could go wrong
- This is a Phase 2 trial with only 150 participants, so results may not apply to everyone. The program requires significant effort and access to a smartphone, which could limit participation and success.
