I read an article http://www.healthy.net/scr/Article.aspx?Id=777 . Great, other than this quote:
"Cows have four stomach with which to digest their own milk. Cow's milk is just not fit for human consumption, especially not when it's full of bovine growth hormone and antibiotics. Don't feed your children cow's milk. They just don't need it; in fact it's bad for us all unless you are dying of starvation and its the only available source of protein. The only "healthy" dairy product for homo sapiens (that's us) is yogurt, which is already partially digested with enzymes."
No, when calves drink milk, it completely bypasses two of the stomach compartments: the rumen and reticulum, by means of the esophageal groove. It is digested in the omasum and abomasum by enzymes... much like human children digest breast milk.
It is an error to say that all milk is not a good food for humans, simply because pasteurized milk is a known contributor of many health issues. In a non-compromised/lactose sensitive individual, raw dairy products provide their own enzymes for proper digestion and are a great food for children and adults, when used to supplement a natural whole foods diet.
Lol. Peoples. :P
