The study may have something to do with calcium and weight loss. There was a study done where people taking a calcium supp lost weight compared to control and a few companies are cashing in on it. This is where the "eat dannon yogurt and lose more weight" slogan came from, if you look closely it says that their information has to do with calcium supplementation and not dannon yogurt.
How bad is IGF-1 and those other things in milk? Cancer is uncontrolled growth, so if you take something that accelerates growth (steroids, GH, igf-1) it will also accelerate tumor growth. Tumero, tell me if I"m wrong, but this was my understanding. Either way, that is how steroids got the bad rap for causing cancer and other things. Basically, are those two things tied into tumor growth or causing tumors? If it has been shown to cause cancer I'll look into it more, if it has been LINKED to cancer and whatnot I'll continue to drink my milk.
