Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A total of 65 participants with hypertension and low access to high quality food will be enrolled to test the feasibility of using commercially available grocery delivery services, simultaneous to a robust behavioral intervention, to improve adherence to the Dietary Approaches to Stop Hypertension (DASH) eating pattern. The behavioral intervention will include skills training, nutrient goal setting, self-monitoring via dietary tracking, personalized text message feedback, and adaptive health coaching. Participants will also receive a membership to Instacart+ and weekly grocery list recommendations from a health coach. The primary outcome will be indicators of feasibility, including acceptability, demand, implementation and practicality and adaption. Change in DASH adherence and blood pressure will also be evaluated. The intervention period for participants will be 4 months.
