A bit of additional information about some terms mentioned in previous Milk write-ups.
1. Protector of Mankind and why address a related topic: if humans should/ought to drink milk or not. In the "modern western society" it's not done to breasfeed babies, or accepted for just a couple of months, whereas in other parts of the world this may continue up to three years.
(side info: It is healthy for the baby as well as the mother to breastfeed. For the baby, because of the nutritional value, developing the flora in the intestine and their immune system. The mother will have less chance to develop breast cancer in a later stage in life.)
This would suggest that after those 3 years you won't need milk anymore. This is true for people with a darker skin colour, but not for the white people. People with a darker skin produce more vitamin D, more than white people who spend time in the sun. But the physiology of the white people have to compensate for that loss. This is done via drinking of milk: the lactose (milk sugar) separation (via beta-galactosidase) and uptake of the resulting glucose and galactose is related to this vitamin D production (the processes involved are not really clear at the moment of writing) (and facilitating calcuim uptake too). Further, this ability is NOT a gene mutation. All people on earth do have the enzyme beta-galactosidase when they're born, and will use that enzyme while they're breastfeeded. However, when you don't drink milk anymore, there's no use for the body to keep on producing the enzyme, aka: it is a relative deficiency.
This relative deficiency is considered an illness (...) and called lactose intolerance: instead of nicely separating the two sugars, the flora will ferment it anaerobically, attracting water and producing CO2 and a little bit of CH4 (carbon dioxide and methane). hiha, you're a bioreactor ;-)

2. bs says "cows which have been pumped up with human growth hormone, which is just really gross to me." Well, nope. Cows are pumped up with BST, an acromy for Bovine SomatoTropine, which is a cow growth hormone, and legal in the United States, but not in the European Union, although the US wants to push it into our throats during every GATT discussions and threatens with sanctions. Besides, there's more BST remaining in the meat than in the milk.
Maybe even more doubtful is the use of the vaccination/immunization treatments of the livestock which is correlated (a statistically significant positive relation) to the ever increasing occurence of milk protein allergy because of the transferred antibodies via the milk (uhm, researchers think it's the antibodies to blame, they're not 100% sure about that).
