Deficiency Of Potassium

The kidneys excrete excess potassium from the body, and deficiencies are rarely found in people on a normal balanced diet. A deficiency may result in fatigue, cramping legs, muscle weakness, sluggish reflexes, acne, dry skin, mood swings and irregular heartbeat.

A shortage of potassium in body may cause a fatal condition known as hypokalemia, resulting from diarrhoea, increased diuresis and vomiting. Hypokalemia can occur in people with a chronic disease or due to ageing process. Deficiency symptoms include muscle weakness, ECG abnormalities, decreased reflex response, congestive heart failure, cardiac arrhythmia and respiratory paralysis.

If the fluid and electrolyte balance is not restored, the risk of heart failure increases.

Potassium deficiency increases acid levels in the body, lowers the natural pH balance, causes problems with the formation of connective tissue. Kidney diseases (such as acute renal failure), diabetes can also cause fluctuations in the levels of potassium. Many medications such as diuretics, cortisone, prolonged use of aspirin, and laxatives also cause depletion of potassium.

Dietary sources of potassium:
Eating a variety of foods that contain potassium is the best way to get the required amount. Individuals who eat a balanced diet do not need potassium supplements. Foods, which are rich sources of potassium include turnips, whole grains, molasses, fish, citrus fruit, apple cider vinegar, bananas, avocados, yoghurt, tomatoes, poultry, oranges, apricots, potatoes (especially their skins), leafy green vegetables such as spinach, lettuce; and meat. One large orange will supply one with 250 mg of potassium, one-eighth of a person’s daily need. Dried apricots contain more potassium than fresh apricots.

Steaming of foods helps to retain nutrients that are lost through other cooking techniques such as boiling (loss of about 50% of potassium content). Steaming results in only a 6% loss of potassium.
