Eating foods containing iron chelators, such as blueberries, might help reduce your risk of developing Alzheimer's disease according to an article published in Archives of Toxicology.  Researchers at the University of Manchester analysed all the existing evidence for a link between iron and a number of medical conditions. Poorly-bound iron causes the production of hydroxyl radicals which could lead to nerve cell death. Brightly coloured fruits, vegetables and green tea are a good source of chelators which prevent the iron from breaking up.

Alzheimer's Society comment: 'Iron is normally found in the brain and we know that it can become concentrated in the areas damaged in Alzheimer's disease. However, there is currently no evidence that it is a cause of the disease. This review of the existing research provides a useful summary of our understanding of iron and Alzheimer's. Far more research is now needed. Alzheimer's Society is currently funding research to understand the pattern of iron deposits in the brain in Alzheimer's and whether it could be used as a way of detecting the disease by a brain scan.  Read more: medilexicon.com
