An apple a day may keep the neurologist away--and reduce your risk of Alzheimer's and Parkinson's. Quercetin, one of the primary phytonutrients in apples, seems to protect the brain from the cell damage that triggers neurodegenerative diseases, according to animal studies conducted at Cornell University in Geneva, N.Y.

These nutrients tend to be concentrated in the fruit's skin, so the most benefit is likely to come from fresh apples rather than from apple juice or sauce. Blueberries, cranberries, and onions also provide a healthful dose of quercetin.
