Summary

The goal of Nourish is to help adults with high blood pressure enjoy an eating pattern called DASH (Dietary Approaches to Stop Hypertension) to lower blood pressure and improve health.

The primary outcome of the study is 6-month change in following the DASH eating plan, as measured by 24-hour dietary recalls. The secondary outcome is change in blood pressure. Study participation will last one year.
