Minerals : Potassium

Minerals are organic elements present in soil. Plants absorb the minerals from their growth medium. We need very small amounts of each mineral in our diet, but they are essential to maintain all nerve and muscle function, teeth, bones and body cells. Minerals are insoluble in water and need to be bonded with a soluble compound before they can be properly utilised. That is why foods are the very best sources.

Functions of Potassium:
  • Regulates blood pressure and heart beat
  • Healthy nerve and muscle function
  • Regulates digestion

Sources of Potassium:
  • Nuts
  • Avocados
  • Potatoes
  • Sweet potatoes
  • Bananas
  • Apricots
  • Nectarines
  • Raisins
  • Figs
  • Dates
  • Prunes
  • Fish
  • Whole grains
  • Legumes

Deficiency symptoms:
  • Loss of appetite
  • Nausea
  • Drowsiness
  • Thirst
  • High blood pressure
  • Listlessness

Supplements are unnecessary provided the diet includes plenty of fresh fruit and vegetables. Always check with your doctor before taking supplements of any kind. An excess of any mineral can have unpleasant side effects.
