Ageing is considered as the main risk factor for Alzheimer’s disease. Aluminium, a known neurotoxin, accumulates in human brain tissue with ageing. This metal can inhibit more than 200 biologically important functions in all living beings. There are several conflicting reports on the link betweenAlzheimer’s disease and role of aluminium. However, a recent study published in ‘Journal of Trace Elements in Medicine and Biology’ by Prof. Christopher Exley of Keele University, United Kingdom, indicated presence of 10 times more quantity of aluminium (> 10 μg/g tissue dry weight in some of the patients of above 60 years of age, suffering with Alzheimer’s disease than in normal individuals. Presence of high levels of this metal in the brain clearly indicates its likely effect in disease progression. As its role in Alzheimer’s disease is suspected, cooking food in aluminum vessels, a routine practice in many places, is not advisable, because of possible leaching of this metal at cooking temperature.
