Just came across an intriguing abstract from the current American Diabetes Association's currently ongoing scientific conference. Basically, researchers took two groups of mice (from a mouse strain genetically predisposed towards diabetes), and fed one group rat chow supplemented with corn oil, and the other group rat chow supplemented with corn oil and aspartame. After 18 months, the group fed aspartame has significantly higher fasting glucose than the controls: 144 mg/dL versus 105 mg/dL. (Just for perspective, that difference is the difference between a diagnosis of diabetes and a diagnosis of prediabetes, although most people with diabetes have much higher fasting blood sugars at time of diagnosis.)

The usual caveats apply: it's mice, not humans, and not a huge group of mice (40 total, and 17 of them died before the study was complete.) However, two additional points seem worthy of note:


  • The mice fed aspartame had lower body weights and "more favorable lipid data" (presumably cholesterol and triglycerides) than the control group. Which means that if these mice had been people whose doctors were trying to decide whether to screen them for diabetes, they would have seemed to be at lower risk than the controls.

  • The amount of aspartame fed to the mice was 6 mg/kg/day. According to Wikipedia, a can of diet soda contains 180 mg of aspartame. For me to get 6 mg/kg/day would take about 2.5 cans of diet soda a day. Do I drink 2.5 cans of diet soda a day? No, but back in my soda-guzzling days, I did easily. As a person with a genetic predisposition towards diabetes, I am not amused.



I don't actually drink much diet soda these days. It wasn't even a conscious health decision - about the same time I started running, plain water just started to seem more appealing as a way of quenching my thirst. I wouldn't necessarily make a major dietary shift based on just one study, but this study does make me feel good about the shift I've already made.
I've been boggling at this article since I read it, as it's some kind of amazing example of how to wrap a halfway decent point in a bizarre miasma of nostalgic pastoralism and weird ideas about masculinity.

You should really read the article, because it is well-written after a fashion, and also contains a number of striking details, but to summarize: The author has worked as a surgeon in Afghanistan and in Canada, and has observed that lots of people in Canada are fat, while hardly anyone in Afghanistan is. He has also been to Polynesia, and has observed that islanders who have hewed to traditional diet and lifeways are manly paragons of tattooed hotness who can navigate canoes with their balls, while the islanders who have taken to Western things like SPAM and the internets are jiggly and have high rates of diabetes. This is all the fault of urbanization making us unmanly.

So, okay, I basically agree with the premise that the Standard Western Diet is really bad for a lot of people. I'm certainly happier and healthier now that I eat differently. I would like to note that this did not require my learning to go out and kill my own dinner. Nor did it require reclaiming my lost manliness, which is good, because, being a woman, I haven't got much.

Oh, yeah, women. Our author does pause to note that diabetes often makes women infertile, but doesn't really seem to be interested in women beyond their reproductive capacity. He certainly never stops to ask whether the pre-urban lives he is idealizing were particularly fulfilling for women, who presumably were doing things like cooking, raising kids, and hauling water, rather than going out and hunting caribou or making long ocean voyages.

No, what really gets me about this article, besides the literally visceral horror of fat, is the sense that the author is really lacking a sense of proportion. It's like he's all, "Guys! Lay off the Cheetos! Or the world will suffer an epidemic lack of tattooed hotness! Oh, yeah, and kidney failure." (Never mind that I don't think I'd have to go very far in my social circle to locate a type 2 diabetic who is possessed of tattoed hotness.)

Or, I dunno, maybe that angle just stands out to me because I've read about a million articles about how the Western lifestyle is going to kill us, but this is the first article I've read about how it is depriving men of important manly capacities like being able to steer a canoe with your nuts.
November is American Diabetes Awareness Month, and yesterday was World Diabetes Day. So, in the interests of raising a little awareness:

Something like 24 million Americans have diabetes. About 1 in 3 of those people don't even know they have it. Many of them won't be diagnosed until the disease has done irreversible damage to their kidneys, eyes, nerves, or other organs. The tragedy is that this damage could have been prevented if their diabetes was detected and treated early on.

So, if you're at risk for diabetes, please talk to your doctor about getting tested and what you can do to reduce your risk. (Risk factors for Type 1 are kind of complicated. Risk factors for Type 2 diabetes include: a family history of diabetes, carrying excess fat in the abdominal area, and getting relatively little physical activity.) If you have any of the symptoms of diabetes, get checked right away.

If you want to learn more about diabetes, visit the American Diabetes Association website, or feel free to ask any questions here.
So, to help motivate myself to keep up with my new-found jogging habit, I've signed up to do the American Diabetes Association's Step Out event in San Jose in October. My goal is to run the 3 mile course.

I'm going to be blogging my training efforts over on my Step Out page. So drop by if you're interested in whether I ever manage to run all the way up the ramp to the bridge over San Tomas Expressway.

And if you feel moved to make a small donation, you'll be doing good in two ways. First, you'll be helping to fight diabetes, which is a major contender on the world's list of Diseases that Really Suck. And second, when I'm out there pounding the pavement in 90+ degree heat, you'll have given me one more answer to the question, "Why am I doing this?"
