I find that some of Kozisek statements often quoted from research studies which are not conclusive in evidence that drinking RO/demineralised water is bad for health, especially epidemiological studies. Most of the sickness, such as heart disease, osteoporosis and cancer also happens to individuals who doesn't drink RO water. Other factors could have cause these common illnesses.
I encourage you to read this document from WQA: http://www.wqa.org/pdf/Consumer%20Briefs/LowTDS.pdf
This document commented on the research done by Sidorenko and Rachmanin of Russia where the scientific methods used are questionable and the conclusions made are vague or not supported by data. Interestingly, Kozisek's WHO document also quotes the same Sidorenko & Rachmanin report.
In another statement, Kozisek states Nevertheless, severe acute damage, such as hyponatremic shock or delirium, may occur following intense physical efforts and ingestion of several litres of low-mineral water (Basnyat et al.2000). The so-called "water intoxication" (hyponatremic shock) may also occur with rapid ingestion of excessive amounts not only of low-mineral water but also tap water. The "intoxication" risk increases with
decreasing levels of TDS. In the past, acute health problems were reported in mountain climbers who had prepared their beverages with melted snow that was not supplemented with necessary ions. A more severe course of such a condition coupled with brain oedema, convulsions and metabolic acidosis was reported in infants whose drinks had been prepared with distilled or low-mineral bottled water (CDC 1994)."
If you read the original paper ( http://download.journals.elsevierhealth.co...03200707836.pdf ) you will notice that there is no mention of drinking "low-mineral water" by the patient but excessive drinking of water (10 L of water without eating any salt-containing food supplementation for that day and taking part in a rigorous trek in a hot and humid environment, which resulted in profuse sweating) which causes water intoxication.
Kozisek also wrongly intepreted CDC 1994 report ( http://www.cdc.gov/mmwr/preview/mmwrhtml/00032470.htm ) as "infants whose drinks had been prepared with distilled or low-mineral bottled water". No such case mentioned in the original CDC 1994 report. Instead, the original report mentioned that the infants were given tap water or bottled water as a substitute for infant formula before hospitalization. Doctors always advise us not to give 0-6 months babies too much water, just a few sip to wash the mouth will do. The reported cases in the CDC 1994 report has nothing to do with distilled or low-mineral bottled water. Even drinking tap water excessively can cause hyponatremic seizures in babies!
I suspect either Kozisek lacks critical thinking in his study of research papers, or has poor mastery of English (he's a Russian) or drunk while writing his WHO document https://www.facebook.com/frantisek.kozisek/...antisek.kozisek
