There is no link between aluminium and alzheimer's, thankfully, that myth has been shot down .
$orry to be picky, but no it has'nt.........been shot down that is.
The World Health Organisation states that Aluminium is not a PRIMARY (hedging their bets) initiator of alzheimers. The NHS uses words like "cannot be linked to", "current findings suggest". But no one CONCLUSIVELY states that alzheimers is not linked to an excessive intake of aluminium IN SOME PEOPLE.
I am currently on a sabbatical from a nursing degree - I like studying, ok - and my hospital work had me in a ward mostly populated by dementia and alzheimers sufferers. The Consultant neurosurgeon saw it as his duty to make students work so I had to accompany him on rounds with the student doctors and had to be as knowledgable as them......so I had to read up a lot, and I do not mean on the internet.
If you check out some of the alzheimer societies internationally they advise on ways of avoiding the intake aluminium. Added to which there are international standards governing the intake of aluminium from cooking and eating utensils.........which probably indicates that a grey ally oxide coming off your utensils means that your utensils do not meet the mark.
That said though, for every study indicating ally is bad for you there is another indicating it might not be.
But, it most certainly does not fall within the category of camp fire myth. There are serious people doing serious research into the subject and there are a multitude of online papers available to be read, along with medical dictionaries.
