What is the physiological function of the significant potassium content found in split peas regarding cardiovascular wellness?
Answer
It helps relax blood vessel walls to maintain healthy blood pressure parameters.
Potassium is an essential mineral that plays a crucial role in balancing electrolytes and regulating fluid dynamics, which directly impacts blood pressure. The significant amount of potassium present in split peas works antagonistically to sodium in the body. By promoting a balance against excess sodium, potassium encourages the relaxation of the smooth muscle walls lining the blood vessels. This vasodilation effect widens the arteries, which decreases the resistance to blood flow and consequently helps maintain blood pressure within healthy, optimal parameters, providing a direct mechanism for supporting heart health alongside the fiber benefits.
