Animals and all their products have been a part of human life since domestication of wild stock. Straight survival entailed finding food sources and the natural milk of many animals goats, sheep, and cows were soon found to be nutritious and easily obtainable. Nature 'invented' milk, humans just made good use of it. The milk we purchase today in the supermarket however is quite a different story. Much research suggests that this more processed product actually causes calcium to be leached from human bone.

This first website is interesting because one person states the obvious that people in Africa drink the milk without andy ill effect. ( The Massai mix the milk and blood of the cow ) He overlooks though that this is straight from the animal and not processed. But even raw milk is not designed for adults either human or animal.
