The apple's powerful peel

The old saying "an apple a day keeps the doctor away" keeps coming around because it's largely true, and although it's a well-known fact that a diet with lots of fruits and veggies is a healthy one experts aren't sure exactly why -- not completely anyway. But new research is shedding some light on just why apples are so wonderful: the magic may lie in the peel.

So it turns out that apples are not only the greatest sources of cancer-fighting phenolics in the American diet today, but the majority of the benefit is found in the peel, as opposed to the inner flesh, of the fruit.

So don't cheat yourself out of the best part next time you have an apple by peeling it. Just scrub it good and bite right in!
