“In general, most animals are exclusively breast-fed until they have tripled their birth weight, which in human infants occurs around the age of one year. In no mammalian species, except for the human (and the domestic cat), is milk consumption continued after the weaning period. Calves thrive on cow milk. Cow milk is for calves.”

“All mammals nurse their young, and breast milk benefits a newborn infant in ways above and beyond nutrition. In fact, until 1 to 2 years of age, the American Academy of Pediatrics, the World Health Organization, the Institute of Medicine and more promote breast-feeding as optimal. Unfortunately, breast-feeding until that age is often difficult, if not impossible, because mothers have to return to work, and children go off to preschool or day care. So we often replace human milk with the milk of cows or other animals. But at a certain point, we have to acknowledge that we are the only mammals on the planet that continue to consume milk after childhood, often in great amounts. More and more evidence is surfacing, however, that milk consumption may not only be unhelpful, it might also be detrimental. … there’s very little evidence that most adults need it. There’s also very little evidence that it’s doing them much good.”

“The human body has no more need for cows' milk than it does for dogs' milk, horses' milk, or giraffes' milk.”

Michael Klaper (1947) American physician

Speech of July 19, 1985. Quoted in David Robinson Simon, Meatonomics (Conari Press, 2013), p. 193 https://books.google.it/books?id=PY0KUnaIU5AC&pg=PA193.

“Arakawa: After I gave birth, I felt even more of a connection to cows, because my breasts started making milk. My breasts got bigger and my nipples swelled up, and every time my daughter went to suckle them, it reminded me of how I used to squeeze the cows' udders on the farm to get the milk out. [chuckle] It was like my own daughter was milking me.”

Interview with mobuta.com (2004)

“We used to think of cow's milk as a nearly perfect food. However, over the past several years, researchers have found new information that has caused many of us to change our opinion. This has provoked a lot of understandable controversy, but I have come to believe that cow's milk is not necessary for children. First, it turns out that the fat in cow's milk is not the kind of fat ("essential fatty acids") needed for brain development. Instead, milk fat is too rich in the saturated fats that promote artery blockages. Also, cow's milk can make it harder for a child to stay in iron balance. Milk is extremely low in iron and slows down iron absorption. It can also cause subtle blood loss in the digestive tract that causes the child to lose iron. … Some children have sensitivities to milk proteins, which show up as ear problems, respiratory problems, or skin conditions. Milk also has traces of antibiotics, estrogens, and other things a child does not need. There is, of course, nothing wrong with human breast milk — it is perfect for infants. For older children, there are many good soy and rice milk products and even nondairy "ice creams" that are well worth trying. If you are using cow's milk in your family, I would encourage you to give these alternatives a try.”

Context: Hume, and other sceptical innovators, are vain men, and will gratify themselves at any expence. Truth will not afford sufficient food to their vanity; so they have betaken themselves to errour. Truth, Sir, is a cow which will yield such people no more milk, and so they are gone to milk the bull. If I could have allowed myself to gratify my vanity at the expence of truth, what fame might I have acquired.
