It seems like these articles against water filtering and drinking for cures are coming in thick and fast.

I suppose it makes sense. After all pure water is pretty aggressive. Still your title is far too broad to take literally. The article goes into different scenarios. 1 of which is from drinking soft drinks and another during fasting.

Soft drinks contain so many dangerous elements its not a good way of testing.

Since fasting itself on just water can be quite aggressive also, the fact that its distilled would require significant studies of people with the same health - some using distilled while the others use tap, and other use just carbon block filtered.

This article has been around for years. Distilled water does not cause death, it does not leach minerals from cells. A small amount of high mineral Sea Salt works fine, but I have no problem with the pure water. Chet Day is against a lot of things like the Hallelujah diet, distilled water and other alternative health issues. I think its a good idea to read both sides of a question, but experience make me a strong believer in distilled water.

I drank very hard Alkaline Water from a limestone cave for more than twenty years. The excess rock calcium I consumed has settled in my joints. X-rays even showed calcium deposits in my lungs. I hope using things like distilled water and raw apple cider vinegar will help to eventually flush out the useless rock calcium from where it does not belong, and meanwhile I am eating plenty of green veggies in the hope of getting the bio available plant based calcium.
