Overview

The specific aim of the study is to determine whether a freeze dried powder provided by the California Strawberries Commission, can reduce blood pressure in patients with pre-hypertension. The powder is prepared by the California Strawberry Commission (CSC).

Primarily, we would like to find out whether freeze dried strawberry powder lowers blood pressure. In addition we would like to know if the strawberry alters the subject's blood cholesterol and the ability of the subject's blood vessels to relax.
