Milk is for infants and children under 5. Adult mammals can not, as a rule, digest milk. Whites do ok with it as an evolutionary adaptation, but people of mixed descent won't handle it especially as generations progress...
Who is at risk for lactose intolerance?
Between 30 and 50 million Americans are lactose intolerant and certain ethnic and racial populations are more affected than others. Up to 80 percent of African Americans, 80 to 100 percent of American Indians, and 90 to 100 percent of Asian Americans are lactose intolerant. The condition is least common among people of northern European descent.
The normal mammalian condition is for the young of a species to experience reduced lactose (milk sugar) production at the end of the weaning period (a species-specific length of time). In non dairy consuming societies, lactase production usually drops about 90% during the first four years of life, although the exact drop over time varies widely. However, certain human populations have a mutation on chromosome 2 which results in a bypass of the common shutdown in lactase production, making it possible for members of these populations to continue consumption of fresh milk and other dairy products throughout their lives.
Us poor whities, living in the snow and sunless North can digest it so that we can continue ot get the vitamin D and calories necessary in our horrid environment.
Actually, though I have curly blonde hair, blue eyes, am virtually hairless and almost no mellanin, I can't digest milk. There's probably a dark skinned man or woman lurking in my ancestry somewhere...
