An Apple a Day??
According to research at Cornell University, apple phenolic extract has lots of desireable health effects on laboratory rats:
"What we found was that the apple phenolics, which are naturally occurring antioxidants found in fresh apples, can protect nerve cells from neurotoxicity induced by oxidative stress."[Thanks to Ben for the pointer. As Ben points out, Cornell is a school well-known for its agricultural research, and there are numerous apple orchards in upstate NY]
