The China Study: My Response to Campbell

Alright folks, I’ll be honest. I was not expecting my China Study critique, which started as a nerdy personal project pursued in the wee hours of the morn, to generate much interest. Like most of my weird projects, I figured it would be briefly perused by a few number-lovers before fading quietly into the abyss of cyberspace.

Instead, it went viral and racked up 20,000 page views within 24 hours.

I’m surprised, but equally thrilled. My self-marketing skills are pretty dismal, and it was only by the grace of all the bloggers who featured my critique that this page-view boom occurred. Thank you to everyone who helped spread the word. I owe y’all!

This post is going to be quite long (no shocker there) and, in places, a bit more technical than the last. I know not everyone digs science mumbo-jumbo, so I’ll try to keep that to a minimum and explain things like journal quotes in simpler terms.

First, I’d like to address a couple points I’ve seen crop up in reader comments and emails I’ve received. (more…)

A Closer Look at the China Study: Dairy and Disease

Mongolian yaks: A source of Chinese dairy.

I’ll admit it: Out of all the variables in the China Project, dairy is the one I’ve been most eager to analyze. Not because I’m a dairy lover myself (I haven’t touched it in years) or because I’m secretly a billionaire milk tycoon with my own thousand-acre Holstein farm (au contraire; I’m strangely phobic of cows). In his book, T. Colin Campbell makes such a compelling case about casein (a milk protein) as a cancer-promoting agent that I’m left wondering: Does the China Study data shows an equally convincing link between dairy and disease?

After all, the counties studied in the China Project weren’t eating the hormone-laden, antibiotic-stuffed, factory-farmed dairy we find in most stores. Their dairy was from pastured animals—typically sheep, goats, or yaks along with cattle—raised on natural diets in rural areas. As best I can deduce, milk products were neither pasteurized nor homogenized. This means that any connections we find between dairy and mortality variables are probably from dairy itself—not the nastiness that accompanies the dairy Westerners are more familiar with. This could be one of our best opportunities for studying dairy consumption in its raw, natural state. Yeehaw! (more…)

A Closer Look at the China Study: Eggs and Disease

Ah, eggs: Incredible and edible, as the commercial goes. A quintessential staple of American breakfasts, loaded with protein, packed with cholesterol. Bodybuilders chug ’em down en masse, and raw foodists sometimes experiment with them—but could they raise your risk of disease, as T. Colin Campbell claims all animal foods do? Let’s take a look at the original China Study data and find out. (more…)

A Closer Look at the China Study: Fish and Disease

In my last post, I explored what the China Study data says about meat and disease—which turns out to be a far cry from what Campbell reports in his book of the same name. In a nutshell, meat has no statistically significant correlations with any diet-related disease, and actually has a negative correlation with death from all causes and death from all cancers. That means the populations that ate more meat generally had fewer chronic diseases than the populations that ate less of it. While it’s impossible to tell from the China Project alone whether this is because meat was protective of illness or simply corresponded with other helpful factors (like better health care), it does undermine Campbell’s assertion that animal product consumption always went hand-in-hand with disease in the China Project.

(If you’re not sure what the China Study is or why I’ve suddenly made it my life’s purpose to examine every modicum of its data, take a gander at the previous entry for an explanation.)

Of course, the “meat” category doesn’t include fish, eggs, or dairy—so these foods aren’t out of the hot seat yet. In this post, I’ll be looking at fish. Sushi lovers, listen up. (more…)

Exciting Update: Analyzing the China Study

Alright, folks: the hiatus is over. Time to get back into the bloggin’ swing of things!

To kick it off, I want to unveil a special project I have in the works. Some of you are no doubt familiar with the China Study by T. Colin Campbell—a book that has, since its publication in 2005, become wildly popular among vegans and raw foodists as the “final word” linking animal foods and disease. While the book has many strengths, I’ve always been skeptical of its conclusions, and woefully curious about the data Campbell used to decide animal products are universally harmful.

Lo and behold, my knowledge-thirst is quenched! It turns out the entire raw data set is available online for anyone with a bit of spare time (and some knowledge of stats) to analyze:

China Study Data at Oxford University

Not only that, but—after months of searching—I’ve finally managed to get my paws on the original China study book: “Diet, Life-style and Mortality in China,” which is an uninterpreted, 894-page collection of all the correlations the China study data uncovered. Venturing lightyears beyond the effects of just animal protein, this book connects the dots between consumption of specific foods, nutrient status, lifestyle factors, diet habits, and chronic diseases. You can look up fruit consumption, for instance, and see what diseases it correlates with or seems to protect against.  The book is an absolute jackpot of information. And it’s mine, all mine, until July 3rd (when the inter-library loan expires and I have to return it—shucky darns!).

With the data now at my fingertips, I’m researching and analyzing like a maniac. And although I initially started this project out of personal curiosity, what it’s uncovering has been so completely shocking that I’ve decided to post everything I find here on my blog. My next few entries will have some awesome data for you.

But you have to wait, because it’s not in presentable form yet. Oh, the suspense! 🙂

In the meantime, I’ll just say that the findings reaffirm what I’ve suspected for a while: Campbell’s “China Study” book is a spectacular example of how you can cherry-pick data to create a reality that isn’t there. And also, wheat may be one of the most toxic things you could ever put in your mouth. More on that later.

Stay tuned.
