Dr. Campbell's did a study "China Study" about dairy. He says that dairy can switch on cancer genes. What is your opinion on dairy?

The studies that Dr. Campbell did were on mice and also he's done some other studies as well but I think casein is not the best protein in the world. Especially if it's from cows that you don't even know if they had hormones or not. So you're dealing with a protein that is a growth hormone. Think about whey protein too which is another protein in dairy that bodybuilders consume. It has growth potential properties for cancer. But if you're doing a moderate amount of high quality cheese let's say Switzerland cheese that's from cows that are really healthy on top of a mountain top. And you're doing that in a moderate way.
