What role does the high potassium content of black currants play in cardiovascular function?

It helps to balance sodium levels in the body, aiding blood pressure regulation

In the context of cardiovascular health, black currants contribute to maintaining healthy blood pressure levels through the action of several compounds, notably potassium. Potassium is an essential electrolyte that works antagonistically to sodium; a higher intake of potassium facilitates the excretion of excess sodium from the body. Since elevated sodium levels are strongly linked to increased fluid retention and higher blood pressure, the inclusion of potassium-rich foods like black currants helps maintain proper fluid balance. This action directly contributes to lowering resistance within the circulatory system, thereby supporting overall blood pressure regulation.
