The mineral potassium is found in the body's cells and is essential for the regulation of nerve, tissue and muscle action and for maintaining fluid pH levels in the body. It also helps in tissue elasticity, and prevents calcium from being lost from the body through urine.

Research suggests that potassium can help in the treatment of an irregular heartbeat and congestive heart failure. It also reduces blood pressure and the risk of stroke.

Potassium deficiency can be caused by stress and is indicated by muscle weakness, persistent muscle cramps, liver problems and poor digestion.

So what foods are potassium rich?

Potassium can be found in nearly all fruit and vegetables especially:

• bananas
• tomatoes
• papaya
• dates
• peaches
• apricots
• melons

sunflower seeds, almonds, raisins and pecans are also a good source of potassium.
