Potassium

Potassium is an important mineral that supports brain, nerve and muscle function. Adequate potassium intake has been associated with a reduced risk of hypertension and stroke. Potassium is an important electrolyte, helps normalize blood pressure and maintains the acid-base balance in the body.

Potassium Food Sources

Potassium is found in most fruits and vegetables. A daily green smoothie or two should provide adequate levels of potassium.

Potassium Deficiency

Potassium deficiency can cause a potentially fatal condition known as hypokalemia. Other symptoms of deficiency include muscle weakness, confusion, irritability, fatigue, chronic diarrhea, decreased reflex response, respiratory paralysis and cardiac arrhythmia.

Active people who sweat more have a greater dietary need for potassium.

Potassium Toxicity

Potassium toxicity is rare unless there is an excessive intake of potassium salts such as potassium chloride or potassium bicarbonate. Kidney disease can also lead to potassium toxicity.

The Effects of Cooking On Potassium

A significant amount of potassium in foods (up to 70%) can be lost when food is cooked.
