Well there is no doubt that heat would destroy some of the valuable things in raw milk but much of the well rounded nutrition is still there. A case of good vs better.
It's been a long time since i've had raw but did drink it semi-regularly with no ill effects. I take to most milk very well btw, but sometimes i wonder if that calmness is the opiate effect.
A slightly newer topic is homogenization btw, the changes that take place afterward and what it may mean for absorption/digestion. I don't have my links handy atm but a quick search at the other forum would bring up details and links from some of the most knowledgeable members.
