Potassium is an important mineral in human body which plays a key role in heart function and muscle contraction.

When kidney function is poor, increased intake of potassium can cause your potassium level rise too high leading to irregular heart beat, weakness and shortness of breath.

It is very important to limit your potassium intake especially when high potassium level in your blood stream.
Your potassium level is               mg/dL (Normal range: 3.5 – 5.0mg/dL).

Therefore, AVOID high potassium food such as

  • Wholegrain cereals, bread and biscuit.
  • Nuts, seeds and products, e.g. chocolate, peanut butter.
  • Coconuts and products, e.g. coconut milk, kaya.
  • All fresh/canned fruit and vegetable juice, herbal medicine drinks, strong tea/coffee, cocoa and malted beverage, milk, wine
  • Brown sugar, molasses, maple syrup, toffees, liquorice
  • High potassium salt substitute, bottled sauces, meat and vegetables extract, essence of chicken, stock cube.
  • Fruits and vegetables from the high potassium group.
