Out of the 5,000 different mammalian species, human beings are the only mammals that continue to drink milk after weaning, and then they drink it from another species. There are several reasons why we do so. For example, we were taught in school and by our parents that we needed milk to build strong bones and teeth. We are also influenced by dairy commercials on TV, and of course, why argue.... we enjoy the taste of ice cream, cheese, and yogurt! Lastly, we tend to follow cultural norms, never stopping to think and question their validity or why we do them.
Dr. Michael Klaper grew up on a dairy farm in northern Wisconsin where he began milking cows when he was 8 years old. Since then, Dr. Klaper realized that, "The purpose of cow's milk is to turn a 65-pound calf into a 700 pound cow as rapidly as possible. Cow's milk IS baby calf growth fluid. No matter what you do to it, that is what the stuff is. Everything in that white liquid - the hormones, the lipids, the proteins, the sodium, the growth factors like IGF-I are all there to start that calf growing into a great big cow, or else they would not be there. Whether you pour it on your cereal as a liquid, churn it into butter, curdle it into yogurt, ferment it into cheese, or add sugar and freeze it to make ice cream... It's baby calf growth fluid!"
