Water is definitely a tough debate. . here are some of my thoughts.
For washing, showering, etc., the best thing is to get an RO filtration system and water softener. Hard water is more difficult to wash with, and you have to use more soap, etc. Also it's probably not the best idea in the world to be inhaling chlorinated / fluorinated water vapor in your shower. Is it going to kill you? Probably not. Halogenated water also breaks down the fabric in your clothes, the enamel on your teeth, and pretty much anything else it comes in contact with.
Drinking water is a whole different debate. Bottled brands such as Fiji, Trinity, and Voss tend to be the best, but are also the most expensive. It is definitely better for the water to be more alkaline, and naturally occurring minerals in the water are good for you. Then again, water isn't exactly the main source of minerals in the diet.
One thing which I personally wouldn't do is drink straight distilled water. It is superb if you are using it to make various forms of extractions (like coffee or tea), however it is for the same reason that I recommend against drinking it straight.
The issue is the osmotic pressure, which is determined by the various substances which are dissolved in the water, as well as their concentrations. If you took an RO membrane and put regular water on one side, and distilled water on the other, the distilled water would move across the membrane according to the chemical gradient set up by the difference in osmotic pressure between the two compartments.
The reason I suggest against drinking distilled water is because the body does not work like an RO system. Water is, for the most part, moved passively as a result of ion pumps in the cell membranes. Therefore if you were to inject distilled water into the bloodstream, the result would be a movement of minerals out from the cells into the blood, rather than the other way around. It is a poor hydrater and will, over the long term, result in demineralization of the bones, and extra strain on the kidneys.
There are a few locations, the lower large intestine being the most notable, where there are water pumps, however these are used when it is necessary to get large amounts of water out of the body, usually when an infective agent has unhealthily populated the colon.
That being said, I can think of two situations where you may want to drink distilled water. One is if you are drinking it in moderate amounts (<8 oz) along with a high carb or protein meal. The water will help to activate hydrolytic enzymes in the gut and also help to extract some minerals out of the food. Then again, a highly alkalinized spring water, like Trinity, may work even better. I am not aware of any research comparing the two.
The other case is if you are engaging in a short term (<3 days) detox program, but only if you make sure to follow up the program with a course of a high-potency mineral supplement to help replenish the mineral loss sustained during the detox process.
If are eating a meal that is high in fat, the best thing to drink in terms of solubizing the nutrients would actually be a glass (or two
) of red wine. Though a pint of Guinness goes much better with a plate of wings, and it can double as a reasonably nutritious breakfast in a pinch!
The best choice, in my opinion, for straight drinking water would be a form of structured water, such as Penta, AquaDraat, or Angel Fire. Angel Fire http://angelfirewater.com/ is currently my fav as it is alkaline spring water, and is oxygenated as well as structured. The company has also done some preliminary research using a Bio-Electrical Impedance Analyzer (BIA) which indicates that their form of water is more effective at cell hydration then regular spring water.
Again, not the cheapest thing around, but then again, you don't need to drink as much of it. It takes me several hours to put down a liter of that stuff when I could drink a liter of regular water in minutes.
It is not for us to understand love, but simply to make space for it.
