One Year Later: The China Study, Revisited and Re-Bashed

Lest this blog sink further into its eery two-month silence, I think it’s high time for an update!

First item of business: The Ancestral Health Symposium. Due to some serendipitous events, it turns out I’ll be presenting at this hyperventilation-inducingly-awesome event next week. My lecture is at 10:00 AM on August 6th in the Rolfe 1200 auditorium. If you’re lucky enough to have a ticket, I hope to see you there, and to verify my existence for anyone who still thinks I’m a meat industry puppet. Otherwise, unless PETA pops in and sets fire to UCLA, all the presentations should be available online for free shortly after the symposium is over. Woohoo!

Second item of business: Now that he’s outed the project himself, I feel safe in announcing that Mark Sisson is going to be publishing the book I mentioned working on in an earlier blog post, and that it’ll be released mid-2012. I’m super excited, and couldn’t ask for a better publisher to work with. Or one with more impressive abs (see link above). More details to come in the near future.

Now on to the real point of this post. (more…)

Heart Disease and the China Study, Post #1.5

First of all: I’ve got some bad news, folks.

I just learned from a highly reliable source that I am not a “private blogger,” but rather, “very likely a large scale underground defamation campaign against Dr.Campbell.” As a result, all mention of my critique—AKA the Minger Scam—has been yanked from Wikipedia’s “The China Study” page by a vegan editor there. The rationale is as follows:

Just tell me, which “private fun blogger” is able, aside of her alleged full time work and study of “English literature”, to write 36 pages of scientific responses to a professor?!! And again and again??? Either “she” is some sort of very mighty – and very mad and crazy and hate filled – genius, which in itself would be something extremely rare and highly unlikely (really, why would a pretty young girl have so much reason for such a giant ordeal, fight, all that massive work, all that hate???) … Or “she” is in reality another underground [campaign].

Whoops—my bad! I forgot females aren’t supposed to think or write stuff; we’re here to take Home Ec and vacuum in stilettos and learn how to become Good Wives:

On behalf of Minger Scam, Inc., I apologize for any inconvenience we may have caused. ;)

Now onto business.

I’ve got graphs, graphs, graphs galore, but they aren’t really relevant to the upcoming wheat post, so I’m plopping them here instead. In my first China Study critique, I looked at some mortality differences between the five counties that ate the most animal foods and the five counties that ate the least. Here, I’m doing something similar—except this time I’ll be comparing the counties with the super-highest and ultra-lowest heart disease rates and seeing what they do differently in terms of diet.

One of the incredible things about China is the vast difference in heart disease mortality between regions. One county, Fusui, has only 1.5 per 100,000 deaths attributable to heart disease—whereas another county, Dunhuang, has a whoppin’ 184. That’s even more than the US’s figure of 106.

In case graphs freak you out, here’s a summary of what’s below:

  • The healthy-hearted regions almost universally had higher intakes of animal fat, animal protein, dietary cholesterol, and saturated fat than the heart-disease-prone regions.
  • The healthier regions generally had lower intakes of fiber, light-colored vegetables, plant protein, vegetable oil, and—big surprise—wheat flour.
  • Consumption of green vegetables didn’t differ significantly between the high and low heart disease regions. Neither did smoking rates, total cholesterol, or non-HDL cholesterol, although HDL cholesterol looks slightly higher in the regions with excellent heart health.

Does this “prove” anything about diet and heart disease? Nope—there’s the curse of epidemiology again. But we can make the observation that some regions in China exhibited astonishingly low rates of heart disease while eating more animal foods than the Chinese average. And the county with the absolute lowest consumption of animal foods, Longxian, had the second highest rate of heart disease mortality out of all the counties studied. (For the record, I used the China Study II data for this, all of which is available online.) (more…)

The China Study, Wheat, and Heart Disease; Oh My!

(Not only is this woefully, frustratingly, absurdly belated, but it’s also not yet finished. But I hate being a blog tease, so here’s part one!)

If you’ve been following along with the previous China Study entries (and the wild drama that ensued), you know that I’ve been promising an entry on wheat for a while now, mostly because this little snippet snagged so many eyes:

Correlation between wheat flour and coronary heart disease: 0.67

That’s a value straight from the original China Study data. Could the “Grand Prix of epidemiology” have accidentally uncovered a link between the Western world’s leading cause of death and its favorite glutenous grain? Is the “staff of life” really the staff of death? Bwah ha ha.


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: 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…)

A Closer Look at the China Study: Meat and Disease

As promised, it’s time to unveil all this China Study business. Grab a raw, nonalcoholic drink and make yourself comfy!

Let me start by saying that this isn’t an attempt at “debunking” the China Study or discrediting T. Colin Campbell. Quite the contrary. “The China Study” book is excellent in many ways, if only to underscore the role of nutrition in health. If I ever met Mr. Campbell in person, I’d give him a jubilant high-five and thank him for fightin’ the good fight—for exposing the reality of Big Pharma, for emphasizing the lack of nutritional education most doctors receive, for censuring the use of scientific reductionism, for underlining the importance of diet in disease prevention. Campbell and I are on the same page in many ways. His scroll of accomplishments is impressive and I sincerely believe his heart is in the right place, even if I don’t agree with all of his conclusions. (more…)
