We've recently had a good thread on the best temperature of water to drink for absorption during training. Now I would like to know what type of water is the best for consumption, since water is the most important substance we put into our bodies. I've also read that 75% of Americans are chronically dehydrated. It doesn't supprise me. It seems the bottled water phenomenon in the U.S. is quite a lucrative venture. I'd just like to know the facts without all of the hype of advertising. Don't certain types of water contribute to your body's acidity? Which of the following types of water do you drink during exercise and throughout the day? Why do you feel it is the best? Also, how much of it do you drink? Eight glasses, a gallon? Mineral water? Bottled water (such as Evian)$ Spring water? Distilled water? Tap water? Filtered tap water? Doesn't matter?
