Re: random paste thread!
Almost all adult animals are lactose intolerant. Milk is a food specifically evolved to nurture rapid early growth & development in baby animals of the species from which the milk is produced. Animals (including homo sapiens) have evolved such that enzymatic systems for efficient digestion of milk are "turned off" during the maturation to adulthood, as milk is no longer a necessary food for the rapid growth & development that takes place in infancy & childhood. Adult animals very rarely digest well the milk of their own species, much less that of other species.
