Six-year vitamin E supplementation increased tuberculosis risk by 72%
in male smokers who had high dietary vitamin C intake, but vitamin E
had no effect on those who had low dietary vitamin C intake, according
to a study published in the British Journal of Nutrition.

I'm hoping to hear others' comments on this article; it sounds interesting.

Because I am a smoker, I take daily Vitamin C supplements, never mind
dietary intake, and I occasionally take Vitamin E, so I am interested in the
findings of the study.

The study was completed 15 years ago, so I wonder if any further research
has been done on the matter. I also wonder what is the general-population
comparrison of TB rates between Finland and North America, and I find it
peculiar that the TB risk shows up only in males.

Greyhackles, what's your take on this? I mean, besides that I should quit
smoking <g>

Ok, besides that ;-)

Fwiw, the US CDC said in 2007 that the total TB cases in the USA was at an
all-time low - below 4.6 cases per 100000 persons - and was continuing to
decline.

I read the abstract, found the conclusion to be ridiculous, and was left
wondering exactly why they bothered attempting a retrospective analysis of
immune system function (using TB as the key marker) based on the data from a
two decade old study that was focused on how antioxidants affect cancer risk
in smokers.

It's exactly this kind of nonsense that causes the general public to become
numbed to the results found in well-executed studies.

Btw, if I recall the original study correctly, it found the use of
supplemental antioxidants actually *increased* the risk of lung cancer in
smokers.

So - quit already ;-)

Yeah, yeah, I'm workin' on it, and the vitamins are out the window too...

Thanks for your grounded perspective. As always, your comments make good
sense.
