Sunday Aug 21, 2011 (foodconsumer.org) -- Taking high doses of vitamin C may help prevent Alzheimer's disease, a new study in the Journal of Biological Chemistry suggests.

Katrin Mani of Lund University and colleagues conducted a lab study of brain tissue from brain tissue from mice suffering Alzheimer's and found vitamin C dissolved the toxic misfolded protein aggregates.

The amyloid plaques are believed to be the cause for deaths of nervous cells in the brain.

The researchers also found dehydroascorbic acid has the same effect as vitamin C does on the misfolded protein aggregates. 

Dehydroascorbic acid is the oxidized form of vitamin C, which can be formed during the storage of a vitamin C containing juice.

Dietary antioxidants including vitamin C, also known as ascorbic acid, have been associated with reduced risk of Alzheimer's disease and cognitive impairment.

It is believed that there is no cure for Alzheimer's disease - the most common form of dementia that is often found in people older than 60\. An estimated five million Americans suffer this disease.
