Linked by [livejournal.com profile] moominmuppet: Multiple sclerosis patients present high rates of celiac disease.

Just add it to the very long list...

(Disclaimer: I am not officially diagnosed with celiac disease. I have a nonspecific diagnosis of gluten sensitivity (weakly positive antibody test + nausea/vomiting after exposure + strong tendency towards severe migraines the next day.) Gluten sensitivity is complex. A fairly pragmatic theory is that the lesser shades of it are just indicators that reactions haven't progressed enough for the diagnostic criteria of celiac to be present.)

The more I learn about this, the more I realize I've dodged a bullet. Which one, I can't say, but the number of truly horrendous health problems that crop up in most people with gluten sensitivities before diagnosis... well, even if my constant neck/back soreness and recurring tension headaches don't clear up, I've gotten off lightly. (The tl;dr version of clicking those links: diabetes, anemia, epilepsy, autoimmune thyroid disease, peripheral neuropathy, arthritis, esophagitis, kidney disease, cancer, fibromyalgia, chronic fatigue syndrome, and a bunch of other things can be triggered by eating gluten, if you're sensitive.)

Antibody testing for gluten sensitivity should be standard with physicals. The fact that it's not... well, it took a while for doctors to start washing their hands, too. It drove poor Ignaz Semmelweis insane. If you have health problems with an uncertain cause, and you haven't been offered testing, ask your doctor. (Ask for vitamin D level testing, too - that's another hidden cause of multiple health problems that's just arrived on the map.)

That, and as various people have pointed out, there's no guarantee these things won't misfire and give you a huge dose in one spot.

While passing through the airport, I suggest y'all encourage your friendly neighborhood TSA reps to ask their bosses "why aren't we wearing radiation badges, again?"


In other, unrelated and cheerier internettage, have an awesome article about doing steampunk Native American style.

If you can at all cope with the crude results, do not at all go through the backscatter scanners. I have no reason to believe that the millimeter wave technology is unsafe, but as for the backscatters, a number of prominent scientists and doctors speak up:

Backscatter X-rays deliver far more radiation than the TSA is willing to tell you. (thanks [livejournal.com profile] coyotegoth)

The famous UCSF letter going around, summary of which: These things aren't tested for human use; the total *amount* of radiation may be small but the *dose per area* is not; people with pre-dispositions to breast cancer or skin cancer may especially want to watch out; sperm are at risk and so are children; the fuck are you doing, Uncle Sam, giving everyone cancer.

Concerned about high cholesterol? Don't look to lowering saturated fat. Look to lowering sugar.

This info has been "crossing my desk" in various forms for a while now, but I note it has not hit the media extensively.

I was looking some things up tonight because the amount of milkfat in my diet has gone up lately, and it reminded me to share this for the benefit of folks who have not encountered this information...

"There's a subgroup of people at high risk of heart disease who may respond well to diets low in fat," says Dr. Krauss. "But the majority of healthy people seem to derive very little benefit from these low-fat diets, in terms of heart-disease risk factors, unless they also lose weight and exercise. And if a low-fat diet is also loaded with carbs, it can actually result in adverse changes in blood lipids."

While Dr. Krauss is much published and highly respected -- he has served twice as chairman of the writing committee of the AHA's dietary guidelines -- the far-reaching implications of his work have not been generally acknowledged. "Academic scientists believe saturated fat is bad for you," says Penny Kris-Etherton, Ph.D., a distinguished professor of nutritional studies at Penn State University, citing as evidence the "many studies" she believes show it to be true. But not everyone accepts those studies, and their proponents find it hard to be heard. Kris-Etherton acknowledges that "there's a good deal of reluctance toward accepting evidence suggesting the contrary."

(This article is from Men's Health magazine, but it actually does a fairly balanced review of research covering both men and women.)
