Greetings Dr. Graham,
I was looking at some data about how a big % of population
today lives with very few sources of clean, potable water and
how they die of water-related diseases.
I'm guessing it was very hard to find drinking water for the
primitive man since he had very few or no ways to purify it,
dig it or lacked the tools to collect rainwater.
Man can't drink from pollutted sources like other animals
without getting ill, so I was thinking, what if he took all
the water he needed from fruits and vegetables alone?
We know fruits' water is probably the cleanest and most
nutritive water out there and comes in big quantities. For
example on my 811 diet I get about 3,5L of water without
drinking tap water, while when I was eating vegetarian I got a
bit more than 1L, that's more than 2L of difference, not to
mention that for some people it would be even more and that on
the 811 we should need less total water (I think) since we get
less toxins, fats etc.
What do you think about this theory?

Also, I was wondering: I read from a few sources that man
needs around 3L of water a day, but is it meant as only tap
water or water that comes from food and tap water? How much
total water (food + tap water) do we really need?

Thanks,
Vale
