First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a digital program could help adults with high blood pressure who have limited access to healthy food. 67 participants received a grocery delivery membership, personalized meal lists, dietary tracking, text message feedback, and health coaching over 4 months. The goal was to see if the program was practical and well-liked, and whether it improved diet and blood pressure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- behavioral intervention including grocery delivery, dietary tracking, text messages, and health coaching
- What this could lead to
- If successful, this approach could offer a practical way for people with high blood pressure to improve their diet and manage their condition at home.
- What could go wrong
- This was a small feasibility study with only 67 participants and no control group, so results may not apply broadly. The program relies on smartphone access and delivery availability, which may limit who can benefit.
