Drinking pure H2O isn't good for you. As far as I know it could even be deadly. But what if you had a pill with all the minerals usually dissolved in water and washed it down with a nice big glass of distilled water? Would it be more or less the same as drinking tap water? Or would you need more time to dissolve the minerals? What if you threw the pill into the H2O and stirred?

Or am I missing something entirely? I think someone on Lemmy even explained to me the other day what is so bad about distilled water. But I'm stupid today and forgot.

The vast majority of the minerals that your body obtains are from food and drink. The danger of drinking distilled water (due to the lack of mineral content) is very overblown. And the osmotic pressure of tap water is essentially the same as distilled water.

Distilled water is fine unless you are not eating food. Which means you’ll die eventually anyway. Plenty of minerals in solid food.

Distilled water isn't bad for you - it's just lacking in a lot of nutrients you'd usually get from "normie" water. It's still better for you than soda or juices.

Do you have an aversion to tap water? Britas and Berkeys are options if you're concerned about taste or chemicals respectively.

Since you pee out electrolytes along with water, drinking too much distilled water has the effect of washing out electrolytes from your body.

Nah, I don't want to really do this. Seems pretty stupid to me. I was just wondering while I poured some distilled water into my CPAP device.

Now seeing all the answers I've got to experience what it tastes like.

Edit: Just tried it, tasted like regular water.

there's no data that says drinking distilled water is bad for you. if half of a grain of salt would make that water no longer distilled, the leftover minerals in your mouth from the last thing you ate are going to make it no longer distilled

[–] [email protected] 21 points 7 months ago

Distilled water shouldn't be bad at all.

It shouldn't be your only source of water though.

[–] [email protected] 14 points 7 months ago (2 children)

Distilled water isn't bad for you in moderation, but electrolytes and other solutes which are present in impure water are important in maintaining cellular homeostasis, so you'd want to drink standard water on the side. Dissolving electrolytes into distilled water just means that you'll have extra clean normal water. Fun fact, Coca Cola and other soft drinks use distilled water!

[–] [email protected] 22 points 7 months ago (1 children)

electrolytes and other solutes which are present in impure water are important in maintaining cellular homeostasis

But they're barely present. Adding up the common ones, calcium, sodium, magnesium doesn't even get you to 100mg per liter. Meanwhile, the body needs at least 1000mg of calcium, which is 30 liters worth.

As one might expect, water simply isn't a big source of nutrients. Anyone telling you otherwise is trying to sell you something, probably either bottled water, or mineral-powder to add to osmotic filters.

I have an elderly neighbour who is a little on the paranoid side and believed that fluoride in the water was going to poison him. He ended up buying a distiller, and he started to only drink distilled water. He became very sick and had go to to the hospital where he was diagnosed with hyponatremia. Essentially, if you drink too much distilled water it'll flush out the sodium and other minerals in your body causing cells to expand and burst due to the osmotic pressure. If someone is drinking distilled water it's important that they watch their electrolyte intake. Drinking too much water in general can lead to hyponatremia, but it can happen more easily with distilled water since it's as hypotonic as it gets.

[–] [email protected] 9 points 7 months ago (2 children)

It's really the same thing. Tapwater contains barely any sodium, and the average western person had a harder time bringing down their dietary sodium than keeping it up.

Tapwater contains some 40mg of sodium per liter, one single slice of bread contains some 200mg, at least.

Does your neighbor just not eat or something? The overwhelming majority of electrolytes and minerals come from food, not drinking water. He'd have to fast for a pretty long time before distilled water could remove enough salt to cause hyponatremia.

That homeostasis is important. You would always bloat up the cells in mouth, throat and gut a tiny bit.

So dissolve the minerals before drinking, thats better

I found a short paper in the NIH library since most sources seem to be from water companies.

Other than the water will taste like it's missing something, because it is, there doesn't seem to be any conclusive proof of harm. Calcium and magnesium seemed to be the 2 main things people in even industrialized nations may be short on in their diet that they could benefit from having in their water.

The one thing I did find of interest from the paper was this:

This processed water has no residual chlorine and stored or dispensed in PVC can/bottles provides no protection against probable microbial contamination due to handling which is taken care of in conventional system of water supply having free residual chlorine.

So when you dispense it after distillation, it is more prone to some forms of contamination that treated water.

I'm not sure the purpose of removing minerals to just add them back in. You would have to figure out the "blend" you prefer, and the supplement industry is not free from controversy, so being positive what you're reintroducing to the water is now a question. With tap water, you should be able to get a report of it's composition from your water company.

This is almost literally the process Coca-Cola uses for its Smartwater brand. People outside Coca-Cola have described the process of removing everything then adding it back as dumb though. I wonder why

[–] [email protected] 6 points 7 months ago (2 children)

There is nothing wrong with drinking distilled water except it'll taste bad.

[–] [email protected] 8 points 7 months ago (1 children)

Distilled water shouldn't have a taste.

[–] [email protected] 3 points 7 months ago

I just tried it. It tasted just like regular water to me.

[–] [email protected] 3 points 7 months ago

Yeah. Distilled water isn’t the same as lab grade deionized water.

[–] [email protected] 5 points 7 months ago

I think this would be fine. But the mineral content of that glass of natural water is probably tiny, so the pill would be mostly filler.

My HS chemistry teacher was adamant that distilled water could pull filings out of your teeth. No idea if that's true or not, I doubt she is still alive to ask.

[–] [email protected] 3 points 7 months ago

She died in the name of science.

[–] [email protected] 3 points 7 months ago (1 children)

I don't see why not, though I don't know why you would - distilled water tastes blek. Not as bad as bitter-ass unflavored seltzer water though.

[–] [email protected] 5 points 7 months ago (1 children)

No it doesn't. It tastes like regular ass water. Not like regular ass-water.

[–] [email protected] 3 points 7 months ago

Making an important distinction, my friend.

[–] [email protected] 3 points 7 months ago (2 children)

Why do people drink distilled water? I get that there's some taste from the minerals, but I live in a place with hard water and it tastes fine. I've had fancy bottled water and that tastes the exact same if not worse, I drank distilled water and that basically tastes the same too.

[–] [email protected] 2 points 7 months ago

I've only heard of people drinking it when they're on a life raft in the middle of the ocean. Is there a new trend I'm unaware of?

Tell me more please

Edit: [email protected] answered thanks

[–] [email protected] 3 points 7 months ago

Distilled water is fine for you. Otherwise big gov would be telling you to pack up vitamins/minerals for emergencies (they do anyways, but not because of distilled water worries).

[–] [email protected] 2 points 7 months ago

As I understand your neighbour wants to remove fluoride, can he get an under tap filter that only removes those types of chemicals? If not, why not simply buy mineral/spring water. Where I live it's the same price.

[–] [email protected] 2 points 7 months ago

Yes. Home brewers do this all the time with beer.

[–] [email protected] 1 points 7 months ago

Been drinking distilled water all my life... I even have a countertop water distiller to ensure I always have it available. I prefer the taste of distilled water over RO water

[–] [email protected] 1 points 7 months ago* (last edited 7 months ago) (1 children)

I use to make my own and add the minerals back. You’re essentially doing the same thing. It’s been awhile and this may be a rebrand but I think this is what I used https://a.co/d/hKbbL23

This is how all the top producers make their water really. Like Essentia and smartwater.

[–] [email protected] 3 points 7 months ago (4 children)

Oof, honestly I didn't want to really do it. Sounds unnecessary and stupid to me.

I think that there’s a line which makes destillier water bad. Like when you’re drinking 1250 ml destillied water it’s definitely healthy, but 2500 ml, over a long time, will surely cause some side effects

[–] [email protected] 2 points 7 months ago

Everything is poisonous at some level. Distilled water has absolutely no minerals in it so in a very high quantity it will potentially cause cell death through osmosis - it's also the case that if you exclusively drink it your body will constantly flush minerals you get from water in your pee while not replacing them. Do shit in moderation and enjoy the occasional glass of tap water.
