Dairy is NOT the best source of calcium by any stretch of the imagination. Milk has pasteurized blood, pus, viruses, & antibiotics in it due to over used utters that are hooked up to machines all day. Plus hormones so that the cow is able to constantly produce the shit. I have actually heard that chocolate milk is made from the milk that is most discolored by all that stuff. I'm not sure if that is true but I personally believe it.
