I've spent some time now following up on many of the assertions made by doctors on the notmilk.com site, and I have only found a few statements that I find credible. Just about all of the evils of milk on that site are based on bad science and pseudo-science, exactly what I come to this site to get away from. Specifically, the Crohn's disease link is speculative and is not being borne out by additional research (
http://www.medscape....warticle/540142 ) The most likely explanation at this point is that the paratuberculosis bacterium is opportunistically taking advantage of compromised immune function in Crohn's sufferers. Certainly, if you have Crohn's disease or are otherwise immunocompromised (HIV, Lupus, chemo, etc.), stop drinking milk. For the rest of us with high functioning immune systems, the risk seems nonexistant.
The only credible statements I found are a potential link between hormone-laced or growth-factor-laced milk and cancer (important word, potential). Milk from untreated cows does not raise IGF-1 levels, but IGF-1 is found in milk from cows treated with rBST and may contribute to increased IGF-1 levels in humans. Thank goodness for something factual. Unfortunately for the site, this is not an indictment of milk, but treatment of cattle with growth hormones resulting in increased human risk.
Lucky for me, I've been buying milk from a local dairy that does not treat their cattle with rBST and it's fairly straightforward to walk out to the yard and observe that indeed, these are normal cows with normal sized udders. Also, for those in the USA not close enough to a dairy to check for themselves, there's a label for those who wish to avoid treated dairy cattle. It's easier to find untreated dairy products in most parts Europe than to find treated dairy products and there are local labels to clearly specify which is which, so this issue can be easily managed for citizens of most developed nations.
Based on what I've learned today, I'll keep drinking milk and eating other dairy products. I feel quite confident that this is consistent with my goals of living beyond the current theoretical human lifespan and that anyone who stops drinking milk based on these sites is allowing emotional argument, bad science, and fearmongering to overcome rational discourse. Not to say that some new piece of information won't change my mind tomorrow, but it will have to be based on science, not emotion.
