Dr. Barry Thomas is a consultant for Health Canada.
Here is the position of Health Canada regarding aluminum cookware:
"Aluminum can also leach into food from cookware,
utensils and wrappings, but studies to date have shown that the
amount of aluminum leached from these sources is generally negligible."
I wonder if they ran that one by Dr. Barry.
Actually Dr. Thomas is retired, though still cited as senior researcher on
sundry research projects involving toxicity of drinking water, & cited on
the specific rat-modeled Australian Institute for Biomedical Research
study as that research's "Chief Directorate." If you need an explanation
for how you could be the head of a study not personally conducted, then
it's not surprising you also don't understand the outcomes if you don't
understand the process. The hands-on work was overseen by Dr. Judie
Walton. There were a slew of other authors in the symposium papers
eventually published with Dr. Thomas as first author (because he oversaw
the editing & choices for the book & wrote the introduction) -- everyone
pretty much agreed (as Dr Barry agrees) that aluminum dissolved in water
ends up deposited in brain tissue. None address the specific issue of pots
& pans, but they have definitely put to rest the delusion that aluminum
appears spontaneously in the brain -- it enters the bloodstream from the
intestins as a dietary contaminant.
Aluminum sulfate is ADDED to some metropolitan water systems in the
treatment process & that has had Dr. Thomas's priority to stop, even
though he also has said there is not yet any "proof" that the alumnum is
the cause of senile dementia. When a scientist speaks of "unproven" he's
not general implying the opposite IS proven. And Dr Thomas's specific
statement regarding almuminum as the causal agent was "there is not
conclusive evidence. But we fear that it may." All that is definite is if
you eat or drink anything that has aluminum traces therein, it will find
its way to your brain. The rest may be assumption, but then, even gravity
is just a theory, but we seem to adhere to the earth fairly well without
I gave the specifics. 3.5 milligrams per day JUST from the cookware IF you
don't cook anything acidic like tomato sauce or rubarb (then it'll be
more) or if the water you're boiling is flouridated (then the amount of
aluminum dissolved be still more). But under the best of conditions, a
"mere" 3.5 milligrams per day, day in & day out, just from the cheapy-ass
aluminum cookware you're so proud to own. Add another 10 milligrams (or
more) from a buffered asprin if you're one of those dopes who take a pill
a day, another 30 or 40 milligrams from an antacids, it's starting to look
like a healthy dose. If you REALLY want to cite some physicians who don't
think that's a problem you could do MUCH better than Dr Thomas, who has
never said it's not a problem, only that the greater problem is the amount
of aluminum in drinking water.
Though much is not "proven" in absolute scientific terms, the least likely
thing to EVER be proven is that ANY of the sources of aluminum
contaminants are perfectly healthy & play no role whatsoever & that 3.5
milligrams per day is of no earthly consequence. There for a while (up
into the middle 1980s) even the idea of bodily absorption of aluminum from
diet & water was "unmproven" & Science Diget in the late 70s ran a whole
series of articles among which only about one in ten thought it at all
likely. Now pretty much every scientists agrees it's true -- the arguments
are now over which sources play the largest role, or whether it causes
senility or is a natural byproduct of other causes of senility. The Lancet
report on aluminum contaminants in infant diets lowering their average
intelligence as they develop seems to ME damnably definitive that aluminum
is causal, but scientists are rightly chary of claiming to have discovered

"Oh, sir! The flowers, they are wild," replied the timid creature.
I've been a lurker, but I just can't resist my 2 cents - Aluminum is
the most common element found in the earth's crust. Just about any
water which is not otherwise purified (distilled or ion exchanged) is
going to contain Aluminum.
The increase in concentration through contact with cans and pots will
Also note that Aluminum develops a patina of Aluminum Oxide (*) which
is highly insoluable.

If you care to change 'element' to 'metal' or 'most' to 'third most',
I'll agree with you.
How much and in what chemical form?
How did you come to this conclusion? Are you also saying naturally
occuring aluminum compounds and artifically leached aluminum have the
same biological reactivity?
What happens when you apply acid or a catalytic agent that dissolves the
I'll agree that the Al-O bonds in Al2O3 are quite strong even when
