How does the high potassium content aid cardiovascular function?

It acts as a counter-regulator to sodium, helping to relax blood vessel walls.

Potassium is a critical electrolyte that plays an active balancing role in maintaining healthy cardiovascular function, especially concerning blood pressure regulation. Its mechanism involves acting as a counter-regulator to sodium; when potassium levels are adequate, it helps to mitigate the effects of high sodium intake. Specifically, adequate potassium intake promotes the relaxation of the walls of blood vessels, which in turn supports the maintenance of healthy and stable blood pressure levels. Given that yellow squash is low in sodium and high in potassium, it is positioned favorably for heart health, potentially contributing 10 to 15% of the daily recommended intake for this crucial mineral in a single cooked cup.
