Potassium

Cells, nerves, and muscles do not function properly without potassium. It works with sodium to maintain the fluid and electrolyte balance in cells and tissues, to regulate blood pressure, and to maintain a normal heartbeat. It helps counteract the effects of excess sodium intake, such as edema (fluid retention) and high blood pressure. Potassium is also vital for the transmission of nerve impulses from the brain to every part of the body. It is therefore critical for proper functioning.

Blood potassium levels are carefully regulated by hormones, and any excess intake is normally excreted through the kidneys. Symptoms of excess potassium are lethargy, paralysis, and a slow heartbeat. Early signs of potassium deficiency are apathy, weakness, confusion, and excessive thirst.

Potassium is found in most plant foods, but especially good sources include avocados, nuts and seeds, sprouted whole grains, beans and peas, fresh ripe tomatoes and green juices, bananas, kiwis, and oranges.
