Why is"demineralized" water not safe? How is it demineralized?
Have you thought about getting a water filter for your water supply? Reverse osmosis or ion exchange.
From what I've read you should be getting adequate minerals from your diet anyways. Ive been drinking RO water for like 2 years now, but I take a multivitamin daily as well.
ELI5: Your body runs on slightly salty water, aka saline. By drinking "pure" /demineralized water, you reduce the concentration. If you only drink distilled water with no other mineral intake, you will start bursting/killing your cells due to osmosis. However, most everyone has plenty of salt/minerals in their diet anyways from food, so it's not a problem for most people. TLDR: don't go on an all distilled water diet, and you'll be fine.
For your cells it does not matter if it is distilled or normal water, the concentration of salts is way too low in either case. Hence drinking 15 liters in one go will kill you. Other than that you will have a hard time getting in trouble from drinking to little salts, unless you live at an ocean and only consume that water for salt while also being extremely careful not to take in any salts... perhaps.
Honestly, no idea. It's written on the jugs that it's improper for human consumption and destined to be used in appliances. It might just be that it's not been certified, or maybe the general processing chain is not food grade. I dunno. Or maybe because it's been demineralized it lacks the chemicals considered "essential" for drinking water.
There are no essential ingredients in water. There is usually so little in water that you can compare a liter water to a small piece of beard. Also note that in some areas the water is naturally extremely soft.
Yeah, well the water here is so hard that using a boiler once is enough to have it all scaled up. Like opaque white in a single use.
In college I discovered the physics department's distilled-water tap and started filling my water bottles from that because the regular drinking fountain on that floor was nasty. A classmate tried to tell me distilled water would make me die from dissolving all my minerals away or something, which I poo-poohed and kept drinking it for the taste. In hindsight I should probably have avoided it for the same reason as the big sign on the physics department ice maker, also accessible anonymously from the hallway: "No maintenance is performed to deter bacterial growth". Oops. Well I turned out ~~just fine~~ ~~pretty good~~ okay so all's well as ends without food poisoning.
This water will end up in my espresso machine's boiler, I doubt anything really harmful would survive several hours a day at 95C.
i don't know about the ice maker, but wouldn't they test the distilled-water tap? or is that just something you do in clean facilities.
