A substance abundant in apples and other fresh fruits and vegetables can actually protect brain cells against damage linked to Alzheimer’s disease, researchers say.

Results of studies of rat brain cells conducted by scientists at Cornell University show that the powerful antioxidant, quercetin, can protect the cells against tissue damaging caused by the affects of Alzheimer’s and similar disorders.
 
The study’s findings suggest that eating more antioxidant-rich foods, such as fresh fruits and vegetables, could reduce the risk of developing Alzheimer’s. Fresh apples have some of the highest levels of quercetin per serving size when compared to other fruits and vegetables and may be among the best foods for fighting Alzheimer’s, according to lead researcher C.Y. Lee.
 
Other foods rich in antioxidants include blueberries, red wine, red grapes and dark chocolate.
