What is the primary function of potassium in red potatoes for blood pressure?
Answer
Potassium acts as a vasodilator, encouraging blood vessels to widen.
The role of potassium in managing blood pressure is directly linked to its function as a vasodilator. A vasodilator is a substance that causes blood vessels to relax and widen, which in turn promotes smoother, less obstructed blood flow throughout the circulatory system. Red potatoes are an exceptional source of this mineral, with one medium roasted red potato often providing about 25% of the daily recommended potassium, sometimes surpassing the amount found in a banana. By helping to counteract the effects of salt, this vasodilation effect supports the maintenance of healthier blood pressure levels.
