It is necessary to have enough minerals like potassium for the proper functioning of various organs, cells and tissues of the body. It is also a kind of electrolyte that binds together with sodium, chloride and magnesium, maintaining the conduction of electricity in the body. Potassium is essential for proper heart and muscle functioning, playing a vital role in bone contraction and digestion. The excess of potassium in the body is called hyperkalemia, and the deficiency of potassium is called hypokalemia. Diarrhoea, vomiting, excessive sweating, malnutrition and diuretics cause deficiency of potassium in the body. The potassium deficiency increases the risk of high blood pressure (hypertension), stroke, heart disease, etc. Hence, to maintain a balanced amount of potassium in the body, one must depend on sodium and magnesium. 

Importance of a diet rich in potassium 

Many people recover from potassium deficiency with the help of a diet rich in certain fruits and vegetables such as potatoes, tomatoes, cucumbers, cabbage, cauliflower, capsicum and eggplant. In addition, potassium is also found in whole grains, meat, fish, milk and poultry products etc. 

Takeaway Tips

1. Potassium supplements should not be given to children or taken by anyone without a doctor's advice. 
2. Taking potassium supplements in high amounts may also increase the risk of muscle weakness, slow heart rate, etc. 
3. In addition, people suffering from hyperkalemia and kidney disease should not take potassium supplements at all.

Disclaimer: It is essential to consult a doctor before taking a potassium supplement because it can cause several side effects, such as diarrhoea, abdominal discomfort, nausea, etc.
