What the study is about
Americans continue to consume high amounts of sodium. Potassium is notable for its blood pressure lowering effects but less is known regarding its effect on the vasculature. This investigation seeks to determine the role of dietary potassium on the vasculature in the presence of a high sodium diet in salt-resistant adults.
Being studied: Moderate Potassium/Low Sodium Diet; Moderate Potassium/High Sodium Diet; High Potassium/High Sodium Diet
Conditions: Cardiovascular Risk Factor
