I cannot Emphasize enough Mercola's Message in this article, so many otherwise intelligent people miss the boat when it comes to choosing water:
"In choosing the right type of water for you and your family, you want to aim for pH balance. Distilled water is too acidic and alkaline water is too alkaline. The ideal pH of your water should be between 6.5 to 7.5, which is neutral.
Mountain spring water is in this ideal range. It is some of the healthiest water on the planet because it is "living water". Living water, like "living food is in its raw, natural state the way nature intended.
One of the main reasons I am such an advocate for eating raw, organic vegetables is because these "living foods" contain biophotons, small units of light stored by all organic organisms, including you.
Gravity-fed spring water is alive in much the same way. When you take this vital energy into your body, you are re-charging it with health and encouraging it to return to a whole and balanced state.
Now, when I mention mountain spring water, I don't mean the two-gallon jugs you see sitting on your grocery store shelf. I'm talking about water you bottle yourself from a gravity-fed spring. There's a great website called FindaSpring.com where you can find a natural spring in your area. This is a great way to get back to nature and teach your children about health and the sources of clean water."
