Over on the PCO support list, where most people eat low-carb in one fashion or another (e.g. Atkins, CAD, the Zone), people continually urge each other to drink, drink, drink lots of water - at least eight 8 oz glasses per day. We all know the benefits - hydration, flushing out ketones and other toxins, aid to digestion, etc. But I keep wondering - When did we start needing so much water? It seems hard to imagine paleopeople as having access to all that much water every day, especially if they were nomadic and were often looking for water sources. Were they suffering in continual dehydration?Or do we really not need that much liquid? I know when I go camping, I drink much less than usual, because it's a pain to lug all that extra water that is also needed for washing and cooking. In winter it'd be even more difficult. Cheyenne
