Many years ago a published research paper suggested that aluminium was associated with Alzheimers disease. The link was never substantiated, and in fact subsequent studies have contradicted the original results. The original results were never reproduced, and the original source of the link was shown to be an artifact of the sample preparation technique used in the experiment. (ie, the researchers contaminated the samples themselves, accidentally.) The supposed link has no validity at all. But that has not stopped the mindless bandwagon enthusiasts from going into a fit over aluminium cooking gear. Search on Google and you will find lots of cooking web sites which tell you about the dangers of aluminium, in a most positive manner. Do any of them know what they are talking about? No, they are just parroting. It's all myth and rumour, and all false. It's yet another very typical urban myth.
For a start, aluminium is one of the more common elements on this planet. Your body is constantly in contact with it, and has very efficient mechanisms for getting rid of it. It would be extremely startling if it turned out to be a hazard after so many millions of years of contact. Aluminium is present in many common antacids, and no-one has ever indicted those. Aluminium is present in many anti-perspirants (not that they themselves are a good idea, mind you). An aluminium salt is used to treat drinking water to improve clarity. Enough! But if you want some references, herewith. You can find more via Google.
Finally, it should be noted that the latest crop of aluminium cooking pots do not present an aluminium surface to the food anyhow. These days the manufacturers use what is called a 'hard anodising' finish. This is a hard, dense version of the typical aluminium anodising we see on window frames. Good aluminium tent poles have a form of this too, and I know from experience that the surface is very hard to machine. I have to use a carbide tool on it instead of the more common High Speed Steel tooling used on most metals. So such good cooking pots are very reliable. However, the cheaper plain unanodised aluminium pots and billies will still corrode under acid foods such as tomatoes and apricots. They are OK for boiling water of course.
