How does Potassium in Bok Choy regulate blood pressure?

It relaxes blood vessel walls by counteracting sodium's effects

Potassium is recognized as a mineral whose presence in the diet is vital for maintaining healthy cardiovascular function, particularly concerning blood pressure levels. In the context of dietary mineral balance, potassium actively works to counteract the negative physiological effects often associated with excessive sodium intake. Mechanistically, potassium achieves blood pressure regulation by promoting the relaxation of the walls of the blood vessels. When these walls relax, the resistance to blood flow decreases, resulting in a lowered overall blood pressure reading. Consuming adequate amounts of potassium-rich foods, like bok choy, is thus considered a fundamental component of an eating pattern aimed at supporting long-term heart health.
