I received this book through the Early Reviewers Program, and although the main message is interesting and can do no harm: drink more water, eat more healthy and bio, it's not practical or cheap or easy... What should be eat/drink nowadays? Most nothing... Most of us are not lucky enugh to be able to live in the Nature like the author. But the ecologist message about such a precious and scarce and important resource as drinking water is timely and necessary.
Let'say I'll try to do it as much as I can, nobody lives forever however healthy one eats or however how much "alkaline" water one drinks.
That's another point: Should I buy ph strips and go measuring water, beverages, or buy a very expensive "ionizing" device...? That's not realistic... or very scientific.
It's also genetic background, I'm sure. Some people lead very helthy lifestyles (I try to) and however have poor health, and the contrary is true sometimes too.
Anyway, I give it three stars out of five because it can do no harm, and it can do good... if you stick to what the author says several times during the book: stick to the counsel of your health professional...
