Dietary Approaches to Stop Hypertension (DASH)-patterned groceries and effects on blood pressure in adults treated for hypertension: the GoFreshRx randomized trial
- Randomised controlled trial
Authors' conclusion
Nutrient-targeted grocery ordering appears to be a useful strategy to improve longer-term cardiometabolic health.
Study context

- Primary endpoint
- Research clinic-measured SBP
- Follow-up
- 3 months
