Hi Sylph
If you want to waste a lot of money by all means go ahead and get Kangen water. It is a vastly overpriced device that claims to produce alkaline water by electrolysis. If you really want to drink alkaline water, then add some milk of magnesia, or bicarbonate of soda to the water - yes they are what your local pharmacist would call antacids. However, it is not a good idea to be taking them unless you have a need to. Similarly if you want acid water, drink fruit juice. There is no link between alkaline water and anti -oxidants. By the way, you will notice that things have to be added to water to make it acid or alkaline. Pure water is neutral and will stay that way no matter what you do to it at everyday temperatures and pressures.
The Hallelujah diet - is just another vegetarian diet that recommends high intake of raw plant food, that the body will have difficulty digesting.
There is a lot of quackery when it comes to this area and a lot of scams out there. They are only too willing to relieve you or your money. However, if they make you feel good and you have the money then I suppose they don't do a lot of harm, provided they do not interfere with your evidence based treatment. They just make me angry!
