Potassium

The mineral potassium is involved in water balance, muscle and nerve function, heart function, blood pressure and kidney and adrenal function.  It works in conjunction with sodium and chloride, all of which are mineral salts known as electrolytes.  Although the potassium content of food is important, so is the balance of sodium to potassium as too much sodium (particularly in the form of sodium chloride, or table salt), leads to a disruption of electrolyte balance and diminished potassium.   A low potassium and high sodium diet may be linked to certain cancers and cardiovascular disease.   A diet high in fruits and vegetables provides plenty of potassium in the diet.
