The milk of every species of mammal is unique and specifically tailored to the requirements of that animal. For example, cows’ milk is three to four times richer in protein than human milk. It has five to seven times the mineral content. However, it is markedly deficient in essential fatty acids when compared to human mothers' milk. Mothers' milk has six to ten times as much of the essential fatty acids, especially linoleic acid (incidentally, skimmed cow's milk has no linoleic acid). It simply is not designed for humans. Except for domesticated animals to which we feed milk, humans are the only species that drinks the breast milk of another species, and the only species that continues to drink breast milk into adulthood. Today the top producers give ten times more milk. How was this accomplished? Drugs, antibiotics, hormones, forced feeding plans and specialized breeding; that' show.
