You might be interested in Stephen Walsh's (of the UK Vegan Society) article

on milk and breast cancer which starts at:

 

http://www.vegansociety.com/briefings/milkbreastcancer.htm

 

After a thorough review of the studies to date, he concludes the following:

 

" It is likely that the net effect of low-fat milk on colorectal cancer is

modestly beneficial. For breast cancer, the evidence discussed above

suggests that the various effects of milk are in approximate balance. For

prostate cancer the net effect of milk appears to be notably adverse. In

reference [14] Willett notes that " one of the most consistent observations

has been an association between the consumption of dairy products and

prostate cancer incidence or mortality. " The net effect on lung cancer is

unclear. "

 

It appears that the increase in IGF-1 levels after drinking milk is due to

the protein and zinc content of milk, rather than the IGF-1 content. For one

thing, IGF-1 is a protein and would only have a chance to impact digestive

tract cells before being digested in most people.

IGF-1 is produced by the liver in response to growth hormone output. GH

and IGF are essential hormones and trust me you don't want to have too

little. I have too little GH/IGF-1 and it's called Growth Hormone

Deficency. It's part of why I am in a wheelchair.

 

Dairy products do NOT have " high IGF " or high GH either. Read on.

 

It appears that the increase in IGF-1 levels after drinking milk is due

to the protein and zinc content of milk, rather than the IGF-1

content. For one thing, IGF-1 is a protein and would only have a chance

to impact digestive tract cells before being digested in most people.

 

No. IGF rises in direct response to growth hormone. If your pituitary

gland produces too much GH, you'll have high levels of IGF. It has nothing

to do with the protein or zinc content of milk. There is a connection

between protein intake and GH but it basically means if you're deficent,

it's even more important to get adequate protein, from any source. Zinc is

an essential mineral but it's not connected directly with GH. Even if you

get too much protein (hard) or too much zinc (rare), it won't affect your

GH/IGF levels, as far as I know. And certainly milk is a poor to medium

source of either.

 

Too high levels of IGF are correlated with cancer. As far as I can tell,

there's no evidence that GH causes cancer. But, there is plenty of

evidence that high levels of GH (as reflected by IGF-1 levels in the

blood...GH itself is very hard to measure) increase the growth of existing

cancer cells. So you don't want too much. Too much GH also causes a

(rare) hormonal condition called acromegaly that includes strange

overgrowths.

 

IGF and GH are good things to have. Just remember that they are GROWTH

factors. You must have them to lead a healthy life but sometimes you have

things (cancer cells) you don't want to grow too much. It's a matter of

balance.

 

There is nothing about dairy itself that is connected with GH or IGF. So

then where is the connection? It's Bovine Growth Hormone. BGH is the cow

version of Human Growth Hormone. Commercial dairy cows get it so they will

produce more milk. It causes all sorts of problems, including chronic

mastitis (part of the reason why commercial dairy cows get massive amounts

of antibiotics).

 

Despite what the industry says, BGH causes problems in humans who treat

milk from cows treated with it. There are a bunch of reasons for this but

two big ones are: 1) Humans should have HUMAN growth hormone (bovine growth

hormone is for cows); 2) The BGH cows get is genetically engineered, not at

all a natural bovine product.

 

One more reason why, if you eat dairy products at all, you should buy

organic. Organic dairy cows don't get BGH and they don't get antibiotics

(unless they are sick and then their milk can't be sold as organic for

several months). Another option of course is to avoid dairy altogether.

Your choice. Just make sure your choices (and your attempts to influence

other people's choices) are done for reasons that hold up factually.
