Potassium

Potassium is the third most abundant mineral in the human body. You should not underestimate the importance of potassium in your diet. Apart from acting as an electrolyte, this mineral is required for keeping the heart, brain, kidney, muscle tissue and other important organ systems of the human body in good condition.


A recent study showed that eating plenty of foods rich in potassium will help cut your stroke risk. The protective effect is thought to be linked to its blood pressure-lowering properties.

Optimal levels are not clear yet, but the World Health Organisation recommends a daily intake of 3,510mg. Warning: If you have significant kidney problems or are on some blood pressure-lowering medications, too much potassium may do more harm than good, so check with your GP if you are in either of these groups.
