Great responses .
Some other things to think about.
life can only exist below a certain temperature (which is way below boiling or steamng point) so if you want to get the most out of what you eat then eat it raw and from an area that has a downfall of water from a treed hillside as you will actually get minerals out of your vegies that usually lack ,otherwise the vegies look great but they are just pumped up with super phostphate and other cemicals.
Organic is better all they way.

Water is right (not tap water) filtered rain in country areas or for tap water boil a few kettles and let the water stand in an open stainless pot overnight to allow the additives that are put in there by law, to dissapate (like florides etc which are deadly in high doses).

You can actually wash out needed minerals from your system with plain water and a squeeze of lemon or orange holds them in. Added colodial minerals is better but very expensive. As a 500ml bottle is 40 bucks, but you only need 3 eye drops worth in each glass if youre into the 3 litre minimum a day thing.
