As for the milk and cookie diet, it depends on the degree to which you think Santa is even human. I know that the "jolly old elf" line in The Night Before Christmas is meant pretty literally. I don't know if I really understood the distinction as a little kid, but you can get away with a lot of the Santa mythos by just saying "MAGIC!"
He doesn't eat the cookies and milk, he feeds them into the back of the sleigh where they power a mr fusion style magic generator.
