It tastes a
lot better. According to
this it is more nutritious. YMMV but any food that is cooked/processed loses nutritional value. In terms of safety, pasteurized milk should have less risk of food poisoning. For the mass market consumer eating mega-Agriculture's lowest bottom denominator food stuff pasteurized homogenized milk is fine. I don't want to be in that herd, because I've had better food. I drank raw (cow) milk all while I was growing up and am back on it (goat) now. I've never been sickened by it. You'd be stunned at what a different product fresh milk is from the processed carton stuff.
As Clod alluded to on the other thread, there is an independence component to home produced raw milk which makes this a hot button issue for me. Generally speaking, when political society demands that I be more dependent on their flawed economy I push back. I don't like to be coerced into having others do for me what I can competently do myself. My resistance to mass societies demands makes my way of life more resilient when there are disruptions both personal and global. That is more important to me than fear of sickness.
