This has actually been known in the scientific community for at least 10 years, as that is when I first heard of the demonstrated debilitating effects of aluminum in the systems of lab animals. They found that animals who had aluminum in their system (from the anti-perspirant deoderant testing) were unable to learn and unable to recall things they had learned in the past, where control animals with out the "anti-perspirant" did not demonstrate any loss in memory function. They determined that the dose ratio to the animals tested was much larger in relation to the size of the animal than that of a human animal and that the effects would be negligible, though it was never formally tested on humans at the time. I think they should re-think this (this article may be evidence of that occuring.) I do not have links to this information but this is from memory in 1992 and a medical magazine & manuals I read back then.
Also, on a related note I had the following experience:
I have a good friend who's father runns a Dialysis clinic and is a practicing MD at the same time. I was interested in this aluminum connection so about 3 years a go I asked him while we were driving some place. Back in the late 80's/early 90's they had been administering a new kind of aluminum medication to the dialysis patients. They noticed that the ones who were on the new medication were developing memory difficulty and motor skill degredation. They decided that it was the new medication, as the patients on the old aluminum drug were showing a normal rate of mental debilitation (due to age.) So they adminsterd an aluminum dissolving drug (this is paraphrased heavily for space) which allowed patients to pee-out the extra aluminum and have it filtered in the dialysis treatment (if I remmeber the latter part right.) After removing the excess aluminum from the system the patients returned to their old selfes again.
But, it was in 1992 (?) that I first heard of the debilitating effects of aluminum on the body. At the time I used an aluminum zincromium based sweat-blocking deoderant (aluminum zincromium is the active ingredient which stops your from prespiring by blocking your poors as it is abzorbed in to your arm pits) or "anti-perspirant". I immediately switched back to the stuff I used before, and though I had an increased ammount of sweat for a few months, my armpits returned to normal (pre-anti-perspirant) and I feela bit better.
Aluminum ingredients are not native to just a few companies products. Aluminum is the active sweat-blocking agent in all anti-perspirant deoderant products I have read the package to.
Aluminum does not all stay in the system, as some of it is needed to keep you in good health (allegedly) and that is processed with out building up. Unfortunately, aluminum does build up in the brain. This is one of the reasons for ex-heavy-duty-pot-heads to appear forgetful or perma stoned, though that largely depends on the quality of the drug and paper involved un use. (this is according to some medical manual I read back in 1991... data may have changed since then about pot and it's alleged aluminum content)
I try to use "natural" deoderants... like Toms of Maine. It doesn't reak like chemical death, and it is only a masque (so you may have to re-apply it in the afternoon or evening, depending on how much you sweat!)
There is a lot more information about this topic but it is usually very hard to find or is obscured by corporate information (similar to cig's in history.)
Back to work!
