>As a short list, here are a few peer-reviewed articles specifically attacking claims made in the China Study (which, by the way, is itself not peer-reviewed):

Claim 1: "\[Protein from dairy products\] almost certainly contribute to a significant loss of bone calcium while vegetable-based diets clearly protect against bone loss". \—[Campbell in 1994 article in Cornell Chronicle](http://www.news.cornell.edu/chronicle/96/11.14.96/osteoporos...)

Debunking of 1: "The results strongly indicated that dietary calcium, especially from dairy sources, increased bone mass …. \[C\]alcium from dairy sources was correlated with bone variables to a higher degree than was calcium from the nondairy sources". —[Campbell in Dietary calcium and bone density](http://www.ajcn.org/content/58/2/219.full.pdf+html)

Claim 2: "\[Due to animal consumption raising cholesterol,\] the findings from the China Study indicate that the lower the percentage of animal-based foods that are consumed, the greater the health benefits. " —[Campbell on p242 of The China Study](http://books.google.com/books?id=KgRR12F0RPAC&pg=PA242)

Claim 3: "Plasma cholesterol is positively associated with animal protein intake and inversely associated with plant protein intake." —[Campbell in 2001 article in Cornell Chronicle](http://www.news.cornell.edu/chronicle/01/6.28.01/china_study...)

Debunking of 2 & 3: "Within China neither plasma total cholesterol nor LDL cholesterol was associated with CVD. … The results indicate that geographical differences in CVD mortality within China are caused primarily by factors other than dietary or plasma cholesterol. … There were no significant correlations between the various cholesterol fractions and the three mortality rates." —[Campbell in Erythrocyte fatty acids, plasma lipids, and cardiovascular disease in rural China](http://www.ajcn.org/content/52/6/1027.full.pdf)

Claim 4: "Liver cancer is strongly associated with increasing blood cholesterol." —[Campbell on p104 of The China Study](http://books.google.com/books?id=KgRR12F0RPAC&pg=PA104)

Debunking of 4: "This produces…an inverse relation between cholesterol concentration and the risk of death from liver cancer or from other chronic liver disease." —[Campbell in Prolonged infection with hepatitis B virus and association between low blood cholesterol concentration and liver cancer](http://ukpmc.ac.uk/backend/ptpmcrender.cgi?accid=PMC1677354&...)

Claim 5: "\[A\]s blood cholesterol levels in rural China rose in certain counties the incidence of 'Western' diseases also increased". —[Campbell on p78 of The China Study](http://books.google.com/books?id=KgRR12F0RPAC&pg=PA78)

Debunking of 5: "\[I\]t is the largely vegetarian, inland communities who have the greatest all risk mortalities and morbidities and who have the lowest LDL cholesterols". —[Campbell in Fish consumption, blood docosahexaenoic acid and chronic diseases in Chinese rural populations](http://www.sciencedirect.com/science/article/pii/S1095643303...)

>For fun, notice that every single debunking article I mentioned above is from T. Colin Campbell himself. Yes, seriously. He actually rebuts his own points when submitting peer reviewed articles.* I guess he's more careful with what he says when he's not writing a book aimed at the general public to help convince people to go vegan.
