What is the primary cardiovascular function of potassium found in fennel?
Answer
Acts as a vasodilator, relaxing blood vessel walls
Potassium is a crucial mineral found abundantly in fennel, playing a direct and significant role in maintaining cardiovascular wellness, particularly concerning blood pressure regulation. Its mechanism of action involves acting as a vasodilator. Vasodilation is the process where the walls of the blood vessels relax and widen. By counteracting the effects of sodium, which tends to constrict blood vessels, this relaxing action helps to lower overall systemic blood pressure. This function is vital because hypertension, or elevated blood pressure, is a major risk factor for heart disease, meaning fennel contributes protection through this mineral content.
