I read something recently about surface water in mountainous areas being very mineral-rich, and populations from those areas being more healthy. I'll have to go look it up. John Pavao ---------- > I've been drinking distilled water for quite a while now. My first impulse was to say that distilled water is technology-based and hardly in keeping with the paleo diet. But most hunter-gatherers would have had only surface water to drink, and that water would probably have very little mineral content. So, maybe distilled water is a reasonable modern approximation to taking drinking water out of a stream or lake. Bill Dooley
