Re: "What's in your milk?" 1 Although Ron Kensinger claims that pasteurization reduces IGF-1, the opposite has been found. 2 In addition, there is a huge difference in the ability of the body to regulate endogenous chemical signals compared to those which are foreign. There is a chronic and cumulative effect on growth hormone signalling and a threshhold level that is differentially set for different people. Hormones - by virtue of their purpose - have large effects in small quantities, and sometimes it is the smaller quantities that have a greater influence due to the lack of negative-feedback they'd produce.
