The correct answer is...

Potassium is a key mineral that helps regulate blood pressure by balancing the effects of sodium in the body. Sodium can cause the body to retain water, increasing blood pressure, but potassium helps counteract this by encouraging the body to excrete excess sodium through urine. This process reduces the strain on blood vessel walls and helps maintain healthy blood pressure levels.

Additionally, potassium helps relax blood vessel walls, which further reduces blood pressure and improves overall cardiovascular health. Foods rich in potassium include bananas, potatoes, leafy greens, and avocados. Consuming adequate potassium is essential for managing and preventing high blood pressure.
