Potassium: Body
built 643 days ago
Potassium is an essential mineral that plays a variety of important biochemical roles in the human body. Potassium's most important roles include the transmission of nerve impulses, contraction of muscles, production of energy, maintenance of intracellular tonicity, and regulation of blood pressure. Evidence suggests that diets high in potassium may help to protect against hypertension, strokes, cardiovascular disease, and quite possibly other degenerative diseases.

Potassium is a mineral found in many foods. Potassium balance is necessary to help maintain a regular heartbeat and proper muscle function. In certain conditions potassium levels in the body may be too high.

Potassium is an essential mineral micronutrient in human nutrition; it assists in muscle contraction and in maintaining fluid and electrolyte balance in body cells. Potassium is ... important in sending nerve impulses as well as releasing energy from protein, fat, and carbohydrates during metabolism.

Potassium is involved in the storage of carbohydrates for use by muscles as fuel. It is ... important in maintaining the body's proper electrolyte and acid-base (pH) balance. Potassium may also counteract the increased urinary calcium loss caused by the high-salt diets typical of most Americans, thus helping to prevent bones from thinning out at a fast rate.

Potassium has been implicated in the treatment of heart disease since the 1930s, but some heart disease that is due to malnutrition does not respond to potassium. Indeed, because of the impaired ability of the body to take up potassium, it can be dangerous. Most heart disease patients of the Western world... can benefit from an increase in potassium levels.

Potassium is an essential dietary mineral and electrolyte. The term electrolyte refers to a substance that dissociates into ions (charged particles) in solution, making it capable of conducting electricity. Normal body function depends on tight regulation of potassium concentrations both inside and outside of cells (1).
