Many people are concerned that demineralised water is harmful to their health. The basis of these concerns lies in the fact that demineralised water has very low levels of essential minerals and/or electrolytes, which are essential for a balanced and healthy body.

Minerals are essential for the basic functions of the human body to take place. They help to control bone growth, regulate fluids, normalize nerve and muscle functions, keep up metabolism, grow connective tissues, and so much more.

The main source of minerals is always from our food and diet, not from our drinking water. In order to receive enough minerals for our bodies from water, we would need to drink around 30 litres of water every day at WHO-recommended mineral levels, which is not very practical!

If we have a healthy and natural diet, all of the required minerals and electrolytes will be found in that diet, with or without demineralised water. This shows how little effect the minerals and electrolytes in water play in our health.

People who are fasting though, but still drinking water, should ensure that the water they are drinking contains the recommended levels of electrolytes.
