Aluminum in food and potential role on Alzheimer’s disease of aluminum

Abstract

Several studies have shown the relationship between the aluminum exposure and the Alzheimer's disease. The gastrointestinal absorption of Aluminum (Al) is low. Also, If the renal filtering system works as needed, generally urine can be enough to eliminate overdose (rational over concentrations) of Al. But Al can be found in kinds of foods and drinks such as processed foods (because of additives, packaging materials, utensils…), fresh vegetables and fruits (because of soil) and even in drinking water therefore, in some cases, the Al level may pose a health risk. Chronic high concentration to Al exposure preferably intakes by oral, intravascular ways with also not having a good condition of Glomerular Filtering System of Kidneys (GFR). Nowadays, although mankind is having more Al by oral ways than past and many studies have been conducted to determine whether there is a relationship between aluminum and Alzheimer's disease(AD) or not. Therefore, this review is intended to provide a short summary of the works done in the past and it may warn people about Al intake in the next decade, therefore human can change their life to be more natural less industrial.
