How long have you been drinking distilled water? Always seemed like a common sense thing to do but there are many that think it is unhealthy.
Exclusively, almost one year. Before that it was a combination of distilled water and cheaply filtered water.
One week into drinking only distilled water, I felt much better. I wasn't expecting that. Could be the filtered water I was drinking has some chemicals or heavy metals that were slightly affecting my health negatively. I was using a cheap faucet, carbon filter.
The myths regarding distilled water go like this:
It doesn't have any minerals. So what? Ask anybody who says that which minerals and in what amounts should be in water. They can't tell you because it's all marketing by the people who sell mineral water and water filters. We should be getting our minerals and other nutrients from food, not water. I do add a little bit of Redmond's Real Salt to my water anyway, for other reasons. So that gives me sodium and other trace minerals in my water anyway.
It's more acidic, so it dissolves some of its plastic container and then you drink plastic. This is exaggerated, and we consume many more plastics from other sources than from plastic bottled, distilled water. All you have to do is make sure you don't leave your plastic bottled distilled water in the heat, or exposed to sunlight. Otherwise, buy your own distiller.
I'm considering purchasing my own distiller which is nothing but stainless steel and glass. They are expensive and bulky, but the bigger more expensive ones can distill 8 to 18 gallons per day. The cheap, counter top ones take hours just to make a little less than a gallon.
It's so acidic that it leaches out minerals from your body. That's a myth. People eat and drink stuff many times more acidic than distilled water and that doesn't happen. Your stomach acid alone is many times more acidic.
As for filtered water, the best filtration system is reverse osmosis. The problem is that the best filtration system can filter only 98% or less impurities. It also wastes tons of water which stays behind in the filters. It's also very high maintenance and expensive, replacing filters, water lines, etc. For that kind of money and trouble, I'd expect water that's 100% pure of contaminants.
The process of distillation is simply boiling pure H2O out of its contaminants. The water (with its contaminants) is boiled, the pure water then turns into steam and is captured and cooled.
