Are Low-Carb Diets Killing Sweden? (Also: New Interviews and Raw Vegan Immortality)

I’m occasionally stricken by a wave of crippling, all-consuming terror. Sometimes it’s because I can’t find my wallet. Sometimes it’s because I hear the unmistakable sound of Smitty throwing up on my bed. Sometimes it’s because I take a few wrong turns on Youtube and accidentally learn what Piccinini animal-human hybrids are (what is seen cannot be unseen). But these days, it’s usually because I’ve looked at the calendar and realized that—along with being 25 and really old now—I haven’t posted anything on this blog in almost four months.

What madness!

As most of you probably know, I’ve been chugging away on an upcoming book called “Death By Food Pyramid,” which is the main reason Raw Food SOS has been hosting more tumbleweeds than blog entries lately. Thanks to finding some unexpected political shenanigans to investigate (which I’m really excited to tell you guys about), the release date for “Death By Food Pyramid” is now September 2013. More details to come.

Earlier this month, I recorded an interview that touches upon the USDA’s seamy, pyramid-shaped underbelly (mostly in the second half):

I’ll be writing more about the book soon (and resuming my previous rapid-blogging schedule of six posts a year instead of four), but in the meantime, here’s a new installment of Bad Science Du Jour!

The China Study: Fact or Fallacy?

Disclaimer: This blog post covers only a fraction of what’s wrong with “The China Study.” In the years since I wrote it, I’ve added a number of additional articles expanding on this critique and covering a great deal of new material. Please read my Forks Over Knives review for more information on what’s wrong with the conclusions drawn from Campbell’s casein/aflatoxin research, and if you’d rather look at peer-reviewed research than the words of some random internet blogger, see my collection of scientific papers based on the China Study data that contradict the claims in Campbell’s book. I’ve also responded to Campbell’s reply to my critique with a much longer, more formal analysis than the one on this page, which you can read here.

When I first started analyzing the original China Study data, I had no intention of writing up an actual critique of Campbell’s much-lauded book. I’m a data junkie. Numbers, along with strawberries and Audrey Hepburn films, make me a very happy girl. I mainly wanted to see for myself how closely Campbell’s claims aligned with the data he drew from—if only to satisfy my own curiosity.

But after spending a solid month and a half reading, graphing, sticky-noting, and passing out at 3 AM from studious exhaustion upon my copy of the raw China Study data, I’ve decided it’s time to voice all my criticisms. And there are many.

First, let me put out some fires before they have a chance to ignite:

  1. I don’t work for the meat or dairy industry. Nor do I have a fat-walleted roommate, best friend, parent, child, love interest, or highly prodigious cat who works for the meat or dairy industry who paid me off to debunk Campbell.
  2. Due to food sensitivities, I don’t consume dairy myself, nor do I have any personal reason to promote it as a health food.
  3. I was a vegetarian/vegan for over a decade and have nothing but respect for those who choose a plant-based diet, even though I am no longer vegan. My goal, with the “The China Study” analysis and elsewhere, is to figure out the truth about nutrition and health without the interference of biases and dogma. I have no agenda to promote.

As I mentioned, I’m airing my criticisms here; this won’t be a China Study love fest, or even a typical balanced review with pros and cons. Campbell actually raises a  number of points I wholeheartedly agree with—particularly in the “Why Haven’t You Heard This?” section of his book, where he exposes the reality behind Big Pharma and the science industry at large. I admire Campbell’s philosophy towards nutritional research and echo his sentiments about the dangers of scientific reductionism. However, the internet is already flooded with rave reviews of this book, and I’m not interested in adding redundant praise. My intent is to highlight the weaknesses of “The China Study” and the potential errors in Campbell’s interpretation of the original data.

(IMPORTANT NOTE: My response to Campbell’s reply, as well as to some common reader questions, can be found in the following post: My Response to Campbell. Please read this for clarification regarding univariate correlations and flaws in Campbell’s analytical methods.)

Tuoli: China’s Mysterious Milk Drinkers

Important disclaimer: In light of new information, this post needs to be taken with a really whoppin’ huge grain of salt. It turns out Tuoli was “feasting” on the day the survey crew came for China Study I, so they were likely eating more calories, more wheat, more dairy, and so forth than they typically do the rest of the year. We can’t be completely sure what their normal diet did look at the time, but the questionnaire data (which is supposedly more reliable than the diet survey data) still suggests they were eating a lot of animal products and very little in the way of fruits or vegetables.

At any rate, I recommend not quoting this post or citing it as “evidence” for anything simply because of the uncertainty surrounding the Tuoli data in the China Study. Please see the following posts for more information on the issue of Tuoli’s accuracy:

As I mentioned in the previous post on dairy consumption and disease in China, there’s a fascinating little county by the name of “Tuoli” situated in northwest China—a place quite worthy of nutritional study, due to their unique diet.

They live here:

Which looks like this:

Where they eat a lot of this:

But not a lot of this:

The Tuoli diet is so abnormal for China, in fact, that T. Colin Campbell et al omitted this county from analysis in several China Study papers—such as “Vitamin A and cartenoid status in rural China,” published in the British Journal of Nutrition:

One county (Tuoli County in Xinjiang Autonomous Region), composed primarily of an ethnic minority population of herdspeople, had disproportionately high values for retinol, lipid and protein intake due to an exceptionally high intake of animal foods. This ‘outlier’ was not included in the analysis, to characterize more accurately the average intakes of the rural Chinese population and to avoid the undue influence of one data point on the results.

Given the prevailing beliefs about nutrition and health—such as saturated fat and cholesterol as a cause of heart disease, the necessity of fiber for colon health, the immunity-boosting properties of fruits and vegetables, and the dangers of a diet high in animal fat—it would seem the Tuoli should showcase the health woes that come from breaking every rule in the diet book.

But is that the case? (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…)

What is the “Optimal” Diet for Humans? (Part 2)

Did we adapt to cooked food, or is that idea—ahem—half-baked?

In part 1 of this “optimal human diet” series, I mentioned that there is no single, exact diet that will deliver perfect health for everyone. We’re tough cookies, us humans—and we only made it as far as we did by adapting to whatever happened to land on our evolutionary dinner plates. Mastodon meat, sweet little figs, plant roots—we made food of it all.

Even so, there’s a notion in the raw food world that we’re still best-suited for the type of diet we ate back in the good ol’ days. You know, before we exited the tropics, conquered all corners of the planet, and invented the deep-fried Krispy Kreme (which surely triggered the downfall of humanity). Maybe you’ve heard claims that we haven’t adapted to cooked food at all, that we’re designed to be vegan or vegetarian, and that our digestive systems still look like those of other fruit-munchin’, leaf-chompin’ primates.

But do those beliefs hold up to reality? Let’s take a look. (more…)
