Groceries for Residents of Southeastern USA to Stop Hypertension

Description

Hypertension (HTN) affects half of US adults and is one of the most important modifiable risk factors for cardiovascular disease (CVD) and death.

The DASH diet is a proven strategy for lowering blood pressure in adults. Our proposed clinical trial will evaluate the effectiveness of a scalable solution: home-delivered, low-sodium groceries aligned with the DASH dietary pattern and ordered with dietitian assistance via a virtual supermarket, in reducing blood pressure.

Participants will be assigned to one of two 1-month long interventions: (1) dietitian-assisted, DASH-patterned, home-delivered groceries ordered weekly through Amazon Fresh (or Whole Foods) over 4 weeks or (2) self-directed grocery shopping (monthly stipend and DASH diet brochure) (referent).
