This may have absolutely nothing to do with this subject but I remember when my Dad was first diagnosed as terminal. He had huge cravings for two things... milk and apples. He literally would drink a gallon of milk a day and eat four to five apples. (This craving was even before the diagnosis as well). Prior to that, he would eat an apple on occasion and I don’t remember him ever drinking milk. Now I am wondering if it was the Vitamin D (in the milk). I am still confused over the apples but maybe they will find a link to that eventually?
Apple peels contain a substance that seems to cause lower incidences of some cancers in those who consume apples regularly. There have been studies in the Scandinavian countries. I think it might be the quercetin, but am not positive.
I'll see if I can Google something on those studies.
Here is a link that mentions benefits of apple peel. It is an ad, but I’ve seen studies before and there have been several.
