RO bottled water have all of these minerals added as well. My main question is why spend the money on replacing things that you have removed from the water in the first place? Doesn't really make to waste all that money on a wives tale does it?

actualy they don't.. I have been in the water processing plant a couple times in Dubai, and I have been involved in setting up emergency water supplies after natural desasters.. (which in some cases have become warer sourses for over a year) no remineralization. Oh.. I forgot previously, the city of kamloops is a RO plant also... no remineralization.

I have been working on industral sized RO, Distillers, and Ionization plants for the last 22 years, so I am not just talking out my you know what.. I have seen all kinds of studies and wives tails that were put to rest from studies... and yes it has been studied to death and there are no credable studdies that show a direct health risk from pure water.. only from drinking to much water and they used tap water for that one.

think about it.. you take a mouthfull of water and what happens.. your saliva renders it back to non pure water..

there is some merrit in your sweat thing as this does seplete salts and electrolites, but if you depend on water to replace these something is not right. unless you are an elete athlete who regularly extreamly exerts himself there is going to be no need to suplement your body with water that has minerals and electrolites added. like gator aid. I enjoy the tase of some of the products but thats about it, it realy doesnt do anything for me even when I am playing hockey.

local food in hot climats tends to be heavy in salt and spices, which did tweo things.. in the old days preserved the foods, and also ensured you werte getting your minerals in a extream hot enviorment. pure water is drank with abandon, and especialy now with the bottled water craze.

to answer the second part. people asume ro water is cleaner water which it is and will buy it and pay 10000% more for it than the water out of the tap. now another water bottling company wants a chunk of the pie so they bring out mineralized ro water citing they purafy the water and put back only the good elements, mineralized water is a sales gimic and nothing more. it will let a RO installer sell a add on that you don't need, or it will make people buy a different bottled water because they think it is better for them
