Why we believe drinking mineral water is better than demineralised water.


Dear Reader,in 1980 the WHO compiled an internal report with conclusive results showing demineralised water has unsatisfactory organoleptic properties and that it has a definite adverse influence on the animal and human organism, thus the WHO published guidelines for minimum mineral content in drinking water.

In a recent preliminary report (rolling revision-still under review) by the WHO done by F Kozisek (2004, Geneva, “Health risks from drinking demineralised water”) an informative, independant and well researched overview is given of research that has been done to prove that demineralised and low mineral water (WHO regards a TDS < 100 as “LOW”) can be seriously detrimental to your health. Some important points that research has shown are the following:

1. Low mineral water markedly compromises the homeostasis mechanisms compromising the mineral and water metabolism in the body (WHO 1980).

2. Research indicates that low mineral water leads firstly to: increased diuresis (20% increase in urine output), body water volume and serum sodium concentrations, secondly, decreased serum potassium concentration and lastly increased elimination of sodium, potassium, chloride, calcium and magnesium ions from the body (WHO, 1980).

What this basically means is that demineralised water actually dehydrates you and leaches important minerals from your body (Robbins and Sly,1981, American Journal of Clinical Nutrition). In 1993 the German Society for Nutrition reached similar conclusions.

3. Calcium and Magnesium are very important elements in our bodies. Calcium is a substantial component of bones and teeth and it plays a role in neuromuscular excitability, heart and muscle contractions, intracellular information transmission etc. Magnesium plays a role as a cofactor and activator of more than 300 enzymatic reactions. Recent studies suggest that the intake of water with low calcium levels are associated with higher risk of fracture in children (Verd, 1992), certain neurodegenerative diseases (Jacqmin, 1994), pre-term birth and low weight at birth (Yang, 2002) and some types of cancer (Yang,1997) and an increased risk of sudden death (Eisenberg 1992:Bernardi 1995:Garzon & Eisenberg 1998).

4. Illustrations of the effect of short term exposure to low mineral levels especially calcium and magnesium was seen in Czech and Slovak populations that started drinking reverse osmosis water from home systems between 2000 – 2002. Within several weeks and months complaints of cardiovascular disorders, tiredness, weakness and muscular cramps were reported (NIPH 2003).

5. Lutai (1992) studied 7658 adults, 562 children, 1582 pregnant woman in Ust-Ilim Russia. The populations were split between those drinking water with high TDS value of 385 and the other with low TDS value of 134 (low mineral water). The results indicated that the population with the low TDS drinking water (low minerals) showed higher rates of goiter, hypertension, ischemic heart disease, gastric ulcers, chronic gastritis. Children consuming low TDS water (low minerals) showed slower physical development and more growth abnormalities and newborns showed decreased levels of general health.

6. Demineralised water when used for cooking extracts up to 60% of Calcium and Magnesium from food (WHO 1978, Haring & Van Delft 1981, Durlach 1988).

7. Demineralised water is unstable and aggressive and can leach metals such as copper and poisonous lead from pipes and soldering joints (Kramer, 1996).

8. The Russian technical standard for recycled water on board space ships is that the water must have TDS values between 100 and 1000 (Sklyar,2001).

9. The world health organisation recommends that drinking water have the following minimum levels: Mg >10 mg/l, Ca > 20 mg/l (Kozisek, WHO,2004).

Dear reader, does it not make logical sense that our bodies were not created to consume “pure water”, but natural water with minerals in it as research indicates? Dear reader, you have more facts to your disposal now and can make more informed decisions about what water you will drink. If you are still comfortable with demineralised water then please support the numerous established businesses that can provide you with those products. TriAqua respects the competition and free choice in the water market.

TriAqua was founded to address the deficiency in the SA water market by offering products that are within the recommendations of the World Health Organisation.

We are well aware that this topic is hotly debated worldwide with different opinions and ongoing research. TriAqua will not engage in public debates about water and considers the World Health Organization as a trustworthy and independent source of health information.
