Control Diet
In addition to motivational interviewing-based counseling with a registered dietitian to promote adoption of the sodium-restricted Dietary Approaches to Stop Hypertension (DASH/SRD) eating plan., participants in this arm will also receive an electronically-delivered tailored messaging intervention called Women's and Men's Hypertension Experiences and Emerging Lifestyle Intervention (WHEELS-I).
Participants in this arm will receive motivational interviewing-based counseling with a registered dietitian to promote adoption of the sodium-restricted Dietary Approaches to Stop Hypertension (DASH/SRD) eating plan.
Participants in this arm will receive prepared, pre-packaged meals containing 1150mg of sodium.
Participants in this arm will receive prepared, pre-packaged meals containing 5750mg of sodium.
