That's a myth. Distilled water is perfectly safe to drink, it just doesn't taste very good.

The mineral content in even mineral water (never mind tap water) is miniscule.

Your source confirms that exactly.

"Since distilled water doesn’t contain its own minerals, it 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."

But that it could be a problem. So its not a myth, that it is demineralizing your body. Its a small effect - but its there, and it could have a negative effect on the body.
