First of all, the consumption of red meat in particular in the West has gone down and it is the diet of mainly carbohydrates that have gone up.
Secondly, wha Campbell is doing is trying to correlate the incidence of stomach cancer in China withH Pylori bacteria, without even mentioning H Pylori bacetrial infection in Western individuals, which is very high. Further, 1-2 percent of patients that have H Pylori end up with cancers, so to claim it accounts for the wide difference isjust absurd.
Third, it is not just H Pylori that Campbell claims is the cause, he claims a lack of certain anti oxidants and fermented foods. So if these 3 are attributable to stomach cancer and the basis for it, then in this case his argument against the Western diet causing cancer is absurd, because the the Western diet per his own logic is protective against stomach cancer, while the Chinese diet is not. And BTW, stomach cancers is amongst the most painful forms.
Fourth, Tony Gonzalez isn't a scientist nor is was he subject to a controlled study nor does his placebo claims have any bearing on he assertion of Campbell in regrds to eating meat causing cancer. And contrary to Tony Gonzalez, pretty much every athlete on the planet that is worth a grain of salt eats meat, because it packs more nutrients per serving than a purely vegetairan serving. Michael Jordan's pre-game routing was to eat a steak, plus a potato 3 hours before game time, along with a ginger ale.
Fifth, he hasn't proven anything other than published a book that gained it's popularity on the internet. The EPIC Oxford study on the other hand, done by the Cancer Epidemiology Unit in the University of Oxford actually produced it's results in 2009 in the American Journal of Clinical Nutrition in the largest cancer specific epidemeiological study to date and detailed it's conclusions and overall says there is no general correlation between the two, though there are some'statisticall meaningful' variations differing depending upon the tye of cancer.

The study stated that in certain cases meat eaters had less incidents of particular types of cancers while vegetarians had more. But even this study, none of it deals with randmly controlled studies.
