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…)
