Could you drink distilled water with a mineral pill (swg-empire.de)

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.

You're talking about a carbon steel wrench that rusted away on the bottom of a stainless steel tank due to Galvanic corrosion. It is an extremely common problem for submerged metals. It is usually mitigated by sacrificial zinc anodes, which are slowly dissolved byb the water, protecting submerged structural and mechanical conponents of boats, ships, pipelines, and structures.

The claim from that article is bogus. It was written by someone who does not understand what they are talking about, for an audience that doesn't care.

Rust and corrosion ≠ dissolving. We don't say that we corrode table salt in water. Like I said, if you think that you know better than the World Health Organization and Neil DeGrasse Tyson on this topic feel free to contact them and see what they have to say.

Neither WHO nor Tyson claimed that pure water dissolves metal. That claim came from an article you linked about a Japanese science project, which uses a large tank of pure water as part of a neutrino detector. The entire article was a B-story to that neutrino detection project.

Between the author and the translator, the distinction between "dissolve" and "corrode" went missing. Context restores it for anyone who recognizes the conditions present in that tank. That was simple galvanic corrosion, not some mysterious property imbued on water by distillation or reverse osmosis filtration. The exact same process occurs within fresh water and within water in which considerable amounts of electrolytes and minerals are dissolved (salt water).
