Treatments tested in this trial
Dietitian-Assisted DASH groceries
BehavioralThe DASH ("Dietary Approaches to Stop Hypertension"), is a healthy dietary pattern that lowers blood pressure without reducing weight. The DASH diet emphasizes fruits, vegetables, and low-fat dairy products; includes whole grains, poultry, fish, and nuts; and is reduced in red meat, sweets, and sugar-containing beverages. Intervention Phase: This intervention is a weekly, 4-week DASH dietary intervention. A dietitian will assist participants in ordering groceries in a pattern consistent with the DASH diet to be delivered to their homes. The quantity of groceries will be based on participant Calorie needs and family size.
Self-directed shopping
BehavioralIntervention Phase: Participants will receive some basic information on healthy eating and a stipend during the 4-week intervention period. They are permitted to use the stipend however they choose and will not be asked about how they spent these funds.

Trial outcomes
Primary outcomes
Self-measured systolic blood pressure
This entails 4 measurements, 2 in the morning and 2 in the evening, over a 7 day period (at least 3 concurrent days is acceptable for analysis).
Secondary outcomes
Self-measured diastolic blood pressure
This entails 4 measurements, 2 in the morning and 2 in the evening, over a 7 day period (at least 3 concurrent days is acceptable for analysis).
Seated systolic and diastolic blood pressure (technician-measured)
Seated systolic and diastolic blood pressure measured by a technician in participants' homes, using the office blood pressure device.
Body Mass Index (BMI)
At home measurement based on height and weight measured by a technician via a stadiometer and scale.
24-hour dietary recall
Assessed via self-administered questionnaire using the Automated Self-Administered 24-Hour Dietary Recall (ASA24).
Other outcomes
