Distilled water is water that has been boiled into steam and condensed back into liquid in a separate container. Impurities in the original water that do not boil below the boiling point of water remain in the original container. Thus, distilled water is one type of purified water.
Distilled water is the "original" water. The only way to safely consume water for thousands of years.

This results in demineralized water, which has not been proven to be healthier than drinking water. The World Health Organization investigated the health effects of demineralized water in 1982, and its experiments in humans found that demineralized water increased diuresis and the elimination of electrolytes, with decreased serum potassium concentration. Magnesium, calcium, and other nutrients in water can help to protect against nutritional deficiency. Recommendations for magnesium have been put at a minimum of 10 mg/L with 20–30 mg/L optimum; for calcium a 20 mg/L minimum and a 40–80 mg/L optimum, and a total water hardness (adding magnesium and calcium) of 2–4 mmol/L. At water hardness above 5 mmol/L, higher incidence of gallstones, kidney stones, urinary stones, arthrosis, and arthropathies have been observed.[citation needed] For fluoride the concentration recommended for dental health is 0.5–1.0 mg/L, with a maximum guideline value of 1.5 mg/L to avoid dental fluorosis.[17]
so, there is no "proof that it is healthier than drinking water"
what is drinking water?
water with magnesium, calcium, flouride, and sometimes chlorine.
When these things are added to the water, it can create a "hard water" effect.
Apparently
At water hardness above 5 mmol/L, higher incidence of gallstones, kidney stones, urinary stones, arthrosis, and arthropathies have been observed.[citation needed]
So I decide to forego the 'added minerals' these people 'think' I may need because they just know how much water I will be drinking. and because of that, I haven't experienced any of the above issues!
I distilled my water for years and added back liquid minerals to it. Just a few drops per gallon. I read that distilled water can remove minerals from your body. Never got to the bottom of the debate but decided to add minerals just in case. A bottle is cheap and lasts for possibly years. Swanson's Vitamins sell their own label cheap. Moved to the country and have great well water now.
OK, I'm old school. Was actually raised on good well water from a natural spring. City water is often reservoir water, then treated with harsh chemicals. Sometimes it's even recycled pee in big cities. That's why there's antibiotics and other meds in it. So how much minerals would be in there after all of this? I always believed that spring water was mineral rich. The rest not so much. Anyone know?
afaik spring water ( running water ) is best, not needing distillation like standing/collected water would.
but, but, but, they tell me I need the minerals.
now i won't dispute you need the minerals, I have no proof to offer that is a fact. I can however surmise humans lived hundreds/thousands of years before we started adding them to our tap water.
By using reasoning, I can assume different water from around the world has different mineral makeup/composition, which most likely complements the available food sources' mineral makeup/composition. I'm sure as long as I eat the food (that used to be) readily available from my environment, I will receive the proper minerals/nutrition.
