No. I do not personally own aluminum, but you can still buy
it in the store.

Nope..
But some researchers think there is a link between aluminum and
Alzheimer's - not proven though.

This notion has been thoroughly disproven.

I wouldn't go so far as to say it's been disproven... Only science has
failed to prove it... Here's something I found on the Alzheimer's
Association of America's website...

The following points summarize some of the conflicting findings about
aluminum and Alzheimer’s disease:

• Aluminum is known to be toxic to the nervous system, but its effects
differ from those of Alzheimer’s disease.
• Some studies show elevated aluminum levels in the Alzheimer brain, but
others do not. These studies include both “bulk” investigations
measuring amounts of aluminum by weight and advanced analysis using
laser microprobes.
• There is some evidence that in laboratory cultures of nerve cells,
aluminum promotes aggregation of the protein fragment beta-amyloid into
the amyloid plaques that are a hallmark Alzheimer abnormality. However,
efforts to correlate aluminum levels with plaque density in people with
Alzheimer’s have been inconclusive.
• Research has failed to document a clear elevation of Alzheimer risk in
individuals with occupational exposure to aluminum.
• Studies finding the most consistent link have examined elevated levels
of aluminum in drinking water and increased incidence of Alzheimer’s.
However, there is no evidence that Alzheimer’s disease is more prevalent
in cultures that traditionally drink large amounts of tea, even though
tea is one of the few plants whose leaves accumulate large amounts of
aluminum that may leach into the brewed beverage.

just food for thought... err I guess I should say "lack of thought"

Really? My father's a research in alzheimer disease, and he doesn't
let us use aluminum. He wrote an article on the subject:

Alzheimer's-disease-like changes in tau protein processing:
association with aluminium accumulation in brains of renal dialysis
patients.

Harrington CR, Wischik CM, McArthur FK, Taylor GA, Edwardson JA, Candy
JM

Lancet 1994 Apr 23;343(8904):993-7

Tau protein is a major structural protein of the paired helical
filaments (PHFs) found in both neuritic senile plaques and
neurofibrillary tangles in Alzheimer's disease (AD). Senile plaques
also contain amyloid beta protein (A beta). We did an immunochemical
analysis of frontal cortex from 15 dialysis cases, 5 Alzheimer's
disease patients, and 6 control cases to see whether AD-like changes
in A beta deposition and tau protein were linked to aluminium
accumulation. Dialysis patients were used because they are frequently
exposed to increased levels of aluminium. 8 of the 15 dialysis cases
had insoluble A beta, but there was no association between its
presence and the accumulation of aluminium. However, we found AD-like
changes in the processing of tau protein. In white matter, truncated
tau protein in the PHF-core fraction and endogenously truncated tau in
the supernatant fraction were both increased in association with
aluminium accumulation in the brain. In grey matter, normal tau
protein was depleted and insoluble hyperphosphorylated tau increased
in association with aluminium concentration. Protease-resistant PHFs
were present in grey matter in 2 dialysis cases, a frequency above
that expected for AD in this age group. PHF-core tau in both grey and
white matter correlated with decreased levels of normal tau protein in
white matter. These findings are consistent with a role for aluminium
in the development of AD-like pathology in patients subjected to
prolonged aluminium exposure.

Encyclopædia Britannica

aluminum (Al)

also spelled Aluminium chemical element, a lightweight, silvery-white metal of
main Group IIIa (boron group) of the periodic table. Aluminum is the most
abundant metallic element in the Earth's crust and the most widely used
nonferrous metal. Because of its chemical activity, aluminum never occurs in
the metallic form in nature, but its compounds are present to a greater or
lesser extent in almost all rocks, vegetation, and animals. Aluminum is
concentrated in the outer 10 miles (16 km) of the Earth's crust, of which it
constitutes about 8 percent by weight; it is exceeded in amount only by oxygen
and silicon.

Could be other factors at work here also. Not to disparage your father's

This is just a tiny piece of a big puzzle.

It is in most everything from toothpaste to cloth. Even cotton fibres have
aluminum content. I myself wouldn't like being naked with rotting teeth.

Sorry, the thread was about aluminium cookware, but I forgot the word
"cookware" from my response. He wanted us to stop using aluminum-based
deoderants but we couldn't find any alternatives. I suspect that
cotton fibres yields a much lower rate of aluminium ingestion than
would pots/pans.

Sure. I merely disagreed with an earlier poster who claimed the
aluminium link was "thoroughly disproven."

You are forgetting all the cans that store your food. I imagion that a can
of food sitting on a shelf for a year would absorb a lot more alunminum
than 15 minutes in a frying pan. So no beer,Soda pop, tuna ,salmon or
various other items including drinking boxes that can't be in your diet.

If in fact (and that is a big if) Aluminum was a major factor in alzheimer
everybody since about 1960 would have it. Even preperation H came in
aluminum tubes it still might. Better to worry over what can leech out of
the plastic wraps and containers than to worry over Aluminum.

Medicinal ointments were not packaged in tubes made of aluminum... the old
tubes were made of zinc, even toothpaste tubes were of zinc... but now with the
advent of plastic ...

Better to worry over what can leech out of
the plastic wraps and containers than to worry over Aluminum.

All aluminum cans containing food/drink are coated with food grade plastics,
not because of concerns about alzheimers but to act as an insulator against
electrolytic action, which would quickly cause the can to literally
disintegrate... unless the aluminum containers are somehow damaged no aluminum
ever comes into direct contact with its contents. In fact all steel cans are
coated with plastics as well.

Beer from bottles. Don't drink pop, but when we buy it we buy it in
plastic bottles. Fresh tuna and salmon from the fishmonger. Wine from
bottles. There's almost no aluminium in our food products.

Half of all fifty year-olds have alzheimers. For 80-year-olds the
figure rises to something like 95%. Have you met patients with
alzheimers, or spoken to their families or carers? it's
heart-breaking. I worry a great deal about alzheimers.
