Do you actually want this? I imagine there are probably beneficial minerals and things in water that you want. I stopped only drinking filtered/bottled water exclusively for this reason.

Honest question - what minerals can you get from water that aren't available in the food we eat?

  In Israel, where a lot of drinking water is sourced by reverse osmosis, it appears that the lack of magnesium in drinking water may have increased heart disease: https://www.sciencedirect.com/science/article/abs/pii/S001393511830358X https://www.sciencedirect.com/science/article/abs/pii/S00139... There are of course many magnesium rich foods but the lack of magnesium in water could make a difference at the margins.

    I have a RO system at home, and it has a remineralizing cartridge attached to it. It's pretty cheap and seems to do its job well, the water contains healthy levels of minerals (I tested it in a lab). Why isn't Israel doing it at a large scale? It should be pretty straightforward.

      I am still highly sceptical about this and feel it is more of a "fear mongering" advertising - that this "remineralizing water" thing only started so that the RO filter businesses could create another source of recurring revenue. I also remember reading some study that said vitamins and minerals are better metabolised by our body as chemical compounds, as found naturally in food, than as individual elements in tablet forms. And that is why pharmaceutical companies have now started offering such compounds too - like Calcium + Zinc + Magnesium etc. Which also suggests that we may be better of with such vitamin and mineral supplements, if really required, than "remineralizing cartridges" which release questionable dosages into the water.

Distilled water lacks even electrolytes like potassium and other minerals your body needs. So you may miss out on a bit of these micronutrients if you drink only the distilled stuff. Some studies have found a link between drinking water low in calcium and magnesium and tiredness, muscle cramps, weakness, and heart disease. Also, distilled water may not help you stay hydrated as well as other kinds of water.

I have a multi-stage water filter setup at home that pumps the water through mineral balls as the last step to re-introduce healthy minerals that were removed during the reverse osmosis process. Because it's true, RO water is not suitable for long-term human consumption because of the absence of healthy minerals.

  Interesting, got a link to the product?

    This is the one I have: https://stiebeleltron.ph/product/stiebel-eltron-glacier/ https://stiebeleltron.ph/product/stiebel-eltron-glacier/ I think this particular model is only available in Asia though.

  This is a common myth but it doesn’t make sense if you do the math. There aren’t enough minerals in tap to make a difference compared to the food you eat. Per protocol, we gave our lab rats deionized water that was likely close to zero ppm. All the minerals they need are in the chow. I have drunk delicious RO water at home for decades and have experienced no ill effects, all my blood work for minerals is perfectly normal, teeth healthy etc. >Using an average calcium concentration in public water supplies of 26 mg/liter and a maximum of 145 mg/liter (Durfor and Becker, 1964) and assuming that the average adult drinks 2 liters of this water daily, then the drinking water could contribute an average of 52 mg/day and a maximum of 290 mg/day. On an average basis this would represent 5% to 10% of the usual daily intake or approximately 6.5% of the adult RDA. >Therefore, typical drinking water in the United States, Canada, or Europe provides approximately 3% to 7% of the RDA for magnesium intake by a healthy human. https://www.ncbi.nlm.nih.gov/books/NBK216589/ https://www.ncbi.nlm.nih.gov/books/NBK216589/ I suppose if someone was right on the borderline for mineral deficiency the ~5% of the RDA from water could make a difference but that isn’t really a problem Americans have, if anything they get too much from food. There is some data showing excess calcium is actually bad for heart disease since it is found in atherosclerotic plaques, a problem Americans do have.
