Junshi, Chen, T. Colin Campbell, Li Junyao, and Richard Peto, Diet, Life-style and Mortality in China: A Study of the Characteristics of 65 Chinese Counties, Oxford: Oxford University Press, 1990
Stan, the actual book I think you're referring to is "Mortality, Biochemistry, Diet and Lifestyle in Rural China: Geographic Study of the Characteristics of 69 Counties in Mainland China and 16 Areas in Taiwan" published in 2006.
This book is simply raw data tables and anyone with half a brain knows that looking at a single table means nothing, especially out of context. You are in possession of a full brain and therefore know that doing this kind of thing is manipulative and done only with the intention of making a point that cannot be made with a fuller picture.
Unless you're going to say that Campbell is deliberately misleading people with fraudulent interpretation of the data,...
... then The China Study should be regarded as what Campbell believes as a result of his entire career in the field - including interpretation of all the data and tables in that book. His position on animal protein (not just casein) is quite clear and based on many forms of protein.[/b]
You are only partly right about the casein - that was the protein in the rat studies. However, the human observations that prompted the rat studies showed a relationship between cancer formation in response to aflatoxin and total animal protein intake - not just casein.
In The China Study, Campbell very clearly implicates animal protein in general (not just casein, which was not generally consumed by the Chinese in the study) as a primary factor that affects cancer and mortality. Animal protein intake even at the very low levels consumed by the Chinese (relative to Americans) had a strong correlation.

Anyway, here are Campbell's cites:
Transgenic HBV + casein == liver cancer
Hu J, Cheng Z, Chisari FV, et al. "Repression of hepatitis B virus (HBV) transgene and HBV-induced liver injury by low protein diet." Oncogene 15 (1997): 2795-2801.
Cheng Z, Hu J, King J, et al. "Inhibition of hepatocellular carcinoma development in heptatits B virus transfected mice by low dietary casein." Hepatology 26 (1997): 1351-1354.
Chemical carcinogens + casein == breast cancer
Hawrylewicz EJ, Huang HH, Kissane JQ, et al. "Enhancement of the 7,12-dimethylbenz(a)anthracene (DMBA) mammary tumorigenesis by high dietary protein in rats." Nutr. Reps. Int. 26 (1982): 793-806.
Hawrylewicz EJ. "Fat-protein interaction, defined 2-generation studies." In: C. Ip, D. F. Birt, A. E. Rogers and C. Mettlin (eds.), Dietary fat and cancer, pp. 403-434. New York: Alan R. Liss, Inc., 1986.
Huang HH, Hawrylewicz EJ, Kissane JQ, et al. "Effect of protein diet on release of prolactin and ovarian steroids in female rats." Nutr. Rpts. Int. 26 (1982): 807-820.
Fish protein similarly carcinogenic to casein
O'Connor TP, Roebuck BD, Peterson F, et al. "Effect of dietary intake of fish oil and fish protein on the development of L-azaserine-induced preneoplastic lesions in the rat pancreas." J Natl Cancer Inst 75 (1985): 959-62.
(This one was really comparing n6 to n3 fat, but it is suggestive of an answer to my #2 question.)

Could you please post the reference? Thanks.
TanneryGulch wrote:Heretic, the studies she refers to are the two Hu/Cheng ones you already discussed.
20% casein is a lot -- a diet of nothing but whole milk would be 17% -- but assuming Campbell's generalization from casein to animal protein holds, then this is hardly a case of "too much of anything, even water," since 20% total animal protein is within the range actually being eaten by many people in the developed world, and there are diet gurus with huge followings (e.g. Sears) recommending even more.
In any case, can we at least lay to rest your claim that casein requires aflatoxin?

Actually, I'll go you one better. For only the amazing, low price of $11.53, you too, can own a copy of "The China Study". I would urge you to invest. It might just save your life.
