What's the difference between distilled water ad regular drinking water? And is it OK to drink distilled water?

It's perfectly drinkable, though you will find it doesn't taste of anything. It's the purest water you can get.

It is absolutely pure water because it's been distilled. To distil a liquid, you boil it and then condense the steam back into liquid. Do that to water and it will have no other chemicals in it. It's nothing but H2O.

I live in a hard water area so my regular drinking water has some other chemical compounds in it and that gives it some taste - though it also means I need descaler from time to time! My kettle has calcium compounds of limescale in it, and from time to time my coffee machine gets blocked pipes from that so I need to run some descaler through it or I just don't get coffee out of it. Time I did the kettle again. And I have a big pan that I only use for boiling pasta, and that's getting rough on the bottom - that's limescale and it needs the treatment.

Distilled water is recommended for use in cigar humidors, to stop the cigars drying out, and you also need it for chemistry experiments so the water IS WATER. At school, we had a distiller in the chemistry lab and the school had to pay for a licence for it! Because this is how you make alcoholic spirits like whisky or vodka - after fermentation, you make them stronger in alcohol by distillation, as the alcohol boils at a lower temperature and boils off first before the water. So we could conceivably make some sort of hooch in the thing! Of course the school never did that, it only had it so it could make distilled water, but it still needed a licence.

Bottled water probably isn't great, because bits of plastic can leech into your body. Most bottled water is just plain tap water, despite the commercials showing beautiful snowcapped mountains and streams.

If you can get and afford alkaline water, its pretty pure. You can pour it into glass bottles for purity.

Yes it is perfectly drinkable but here are the recommendations that go along with it;

"Because it doesn’t contain its own minerals, distilled water has a tendency to pull them from whatever it touches to maintain a balance. So when you drink distilled water, it may pull small amounts of minerals from your body, including from your teeth.

Because you already get most of the minerals you need from your diet, drinking distilled water shouldn’t make you deficient. Still, if you are going to drink distilled water, it’s a good idea to make sure you get your recommended daily servings of fruits and vegetables."

knee has correctly explained what distilled water is.

Normally it would be fine to drink but. I would expect it to taste a little flat and lifeless like water that had been boiled and cooled as all the oxygen normally in water will have gone.

Distilled water is fine to drink. It has been put through a process to remove impurities.

Distilled water is- you guessed it- distlled.

I only drink distilled

Distilled water is water that undergoes the process of distillation. In other words, water is boiled and turned to steam, then condensed again in order to remove impurities from the water.

Yes, you can drink it.

IDK the difference exactly, but yes you CAN drink it. I just find it has a peculiar off taste to it.
