Will Compact Fluorescents Screw Up Your Blood Sugar?

I got into a discussion of light bulbs, of all things, on Facebook. A woman named Karen mentioned that, along with their other faults, compact fluorescents -- you know, twisty bulbs -- may raise blood sugar. (The word she used was "purported" -- ie, she was careful to let me know that she wasn't asserting this as proven fact.)

This struck me as important stuff, since we're all being pressured to use the things, and incandescents are being pulled off the market. So I did some googling. I did, indeed, find websites asserting that CFLs can cause an increase in blood sugar, or "may" cause an increase in blood sugar. To be fair, though, most of them were sites that I saw as less than unbiased.

So I went to pubmed.com, and did some searching there. The only medical journal articles I could turn up regarding CFLs were about the possibility of ultraviolet light coming off of them, and about possible variations in the electrical fields around them. "Compact fluorescent light bulb blood glucose" turned up nothing, as did "compact fluorescent light bulb diabetes."

So I'm left with no clear idea as to whether CFLs affect blood sugar or not. I'd be interested in any anecdotal information you all can give me -- anyone noticed a big jump in blood sugar when they switched to CFLs? Or, conversely, anyone switch to CFLs and found their blood sugar unaffected?

I would add, tangentially, that I do think that light is a very powerful, little-explored, nearly-unsung influence on health. If it does turn out that CFLs are bad for health, I will be less than astonished.

Personally, I hate CFLs anyway. I think they emit unpleasant light, I haven't found them to last longer than incandescents -- indeed, I've had some burn out in less than 6 months -- and I resent that I have to hang on to them and take them to the hazardous waste facility. Who was it that thought mercury-bearing bulbs were a good idea in the first place? I also live in fear of breaking one; if you do, you're supposed to discard any rug or carpet that gets contaminated. Like I'm supposed to risk the expensive hand-tied carpet in my living room for a flippin' light bulb?

Most alarming, I've had two heat up to the point where they burned the light socket they were in. One might be a fluke, but two in the same home in less than six months makes me frightened to use them. I'm hoarding incandescents till I can afford LEDs.

So I guess I don't have to worry about CFLs screwing up my blood sugar. Unfortunately, I can't tell you whether you need to worry about CFLs screwing up your blood sugar.
