As it has been stated here many times, cow's milk is for baby cows. Cow's milk is designed to make a baby cow go from 60 to 300 pounds in a matter of months. Humans are the only mammals, other than our cats and dogs because we give it to them, that would even think about drinking another mammal's milk. It does not happen in nature. Milk is extremely mucus forming and has no place in the human diet. If you want calcium, look to leafy, green vegetables as your best source.
