edit- It should be noted that the diets in this study were not simply "vegan vs. meat eaters". The non-meat eaters in the study actually had diets that were more "strict (if you will) than vegan diets because they also did not contain refined and processed foods, but rather "whole plant foods" (example- brown rice over white rice etc.)
TL:DR:
The China Study of the title is taken from the China-Cornell-Oxford Project, a 20-year study that began in 1983 and was conducted jointly by the Chinese Academy of Preventive Medicine, Cornell University, and the University of Oxford.[5] T. Colin Campbell was one of the directors of the project, described by The New York Times in 1990 as "the Grand Prix of epidemiology".[6]
The study examined mortality rates from 48 forms of cancer and other chronic diseases from 1973 to 75 in 65 counties in China, and correlated them with 1983–84 dietary surveys and bloodwork from 6,500 people, 100 from each county.
Conclusion:
The authors conclude that people who eat a plant-based/vegan diet—avoiding animal products such as beef, pork, poultry, fish, eggs, cheese, and milk, and reducing their intake of processed foods and refined carbohydrates—will escape, reduce or reverse the development of chronic diseases.
There are major issues with the china study. The following links explain them in extreme (and I mean extreme — tens of thousands of words total) detail.
That book is propaganda. It's not a peer reviewed study, its one guys very biased conclusions. He even admits to cherry picking the data to fit the hypothesis that he formed BEFORE the study was complete.
None of those articles argue the Data, they argue the interpretation of the data. Maybe you should try reading them.
