The vegan liar and crook Campbell's "China Study" crap is rejected by most doctors and scientists! His book is fraud, its data are not verifiable at all, those data weren't collected or monitored by United Nations or World Health Organization!
Campbell is very afraid to use official confirmed data sources such as UN and WHO. UNFAO is world's best and most reliable data source for dietary consumption for just about every country in the world. UN food data is very precise and well detailed, unlike Campbell's shabby crap. The health and disease data from WHO are also very reliable, detailed and precise. But Campbell the lying vegan refuses to use them because those data expose his dumb vegan lies.
"China Study" is crap! It's based on faulty correlations. The data used are not from reliable source. The only trustworthy food consumption and health condition data sources are UN and WHO which I use in my analysis, and the data are up to date, which Campbell the vegan liar crook is afraid to use because those data totally expose him a fraud and a total liar.
Campbell recommended eating high carb diet which is now proven beyond any doubt to cause many health problems such as diabetes and hearth diseases.
