Argument Against Cancer/Casein Link

[evansmi]

So, I’ve read quite a few “articles” about the infamous “China Study” that supposedly find a huge correlation between casein protein (and supposedly all animal proteins, soy is ok though…) and cancer.

However I just found some of the details of the study for the first time. The articles I’ve read never really went into detail, but wikipedia of all places had some actual information.

T. Colin Campbell’s The China Study (2005), a book about one of the largest nutritional studies ever conducted, describes a direct correlation between casein administered to rats and the promotion of cancer cell growth when exposed to carcinogens. Aflatoxin (a potent carcinogen) was administered to these rats over a 2 week dosing period. The rats were given a 1 week post-dosing period before beginning the test (promotion period). During the promotion period, one group of rats was put on a 5% casein protein diet and another group on a 20% casein protein diet. None of the rats on 5% casein protein developed foci, precursors to cancerous cell growth, and every rat on 20% casein protein developed the pre-cancer foci. It should be noted that all test groups were fed a 20% casein diet for a total of 5 weeks (2-wk acclimation, 2-wk dosing, 1-wk post-dosing) prior to the 12 week promotion period in order to survive the initial aflatoxin B1 (AFB1) dosing, regardless of whether they were in the 5% or 20% test groups.
Other studies conducted by Dr. Campbell on humans confirmed this correlation between the amount of casein protein consumed and the promotion of cancerous cell growth. Dr. Campbell claims to have found a correlation between cancer growth and the amount of casein protein in diet.[18] A 2001 study suggests another milk protein, whey protein, but not casein, may play a protective role against colon tumors in rats.[19] According to a study from the Australian Dairy Council, casein has antimutagenic effects.[20]

So… The cancer that was “highly correlated” with casein, was only after exposing the rats to potent carcinigens. Yes, the casein caused more growth in the cancer cells. But isn’t that what we’re all looking for… growth?

So my take away. If you have cancer, maybe you don’t want to promote an anabolic growth state, as the cancer might also grow. But if you’re healthy and don’t have signs of cancer… seems like this article is just evidence that having a constant flow of amino acids really does cause a growth state.

I’m obviously not a doctor, if you get cancer and die don’t haunt me.

yup, she also reviews “Forks over Knives” quite well too.

essentially, the rats given low casein didn’t get cancer b/c they died sooner from liver issues when compared to high casein group
