Distilled water a potential health risk?

Look at the official water analysis by PUB. No mention is made for magnesium. I reckon if there is any trace element of magnesium in the water, then it must be negligible.

Hence. Andy Ho's article warning that drinking bottled water could be harmful to our body but public/tap water is practically bereft of magnesium to be of any significance to our daily mineral needs.

  1. I found some numbers on Mg by PUB Singapore tap water:

    Water from Choa Chu Kang & Bedok Waterworks Magnesium (as Mg) 1-5 mg/l

    Water from Other Waterworks
    Magnesium (as Mg) 1-3 mg/l

    So the magnesium concentration in public/tap water indeed negligible, like bottled distilled water.
