It's a well-established fact that clean, pure water is a foundational cornerstone of good health. What's open for discussion, however, is what constitutes "clean, pure water." says Dr Mercola.

It's unfortunate, but the value of plain water is vastly underrated by most experts when it comes to achieving optimal health. I'm convinced that we could prevent many of our chronic health problems if we would simply start replacing all soda and nearly all commercial fruit juices with pure water.

As you may know by now, the number one source of calories in the U.S. comes from high fructose corn syrup primarily in the form of soda. Americans drink an average of one gallon of soda each week, and this excessive fructose consumption is a driving force behind obesity and chronic degenerative disease in this country.

Also , drinking alkaline or ionized water is not a healthful choice in the long run, and as you will see, neither is drinking distilled water. During distillation, water is boiled and evaporated away from its dissolved minerals, and then the vapor is condensed and the resulting water droplets collected. Distilled water is an active absorber, and when it makes contact with air, it quickly absorbs carbon dioxide and becomes acidic.

Since it is free of dissolved minerals and other particles, it has the ability to absorb toxic substances from your body and eliminate them. However, although drinking distilled water may be helpful when detoxifying for a week or two, the longer you drink it, the more likely you'll develop mineral deficiencies and an acidic state. You can rapidly lose electrolytes (sodium, potassium, chloride) and trace minerals, which can cause cardiac irregularities, high blood pressure, and cognitive/emotional disturbances.
