An Apple (Peel) a Day
Cornell researchers have identified a dozen compounds in apple peels—all in a class called triterpenoids—that either inhibit or kill cancer cells in laboratory cultures. Other Cornell studies have found that whole apples have the ability to fight cancer cells in laboratory tests and reduce the number and size of mammary tumors in rats. The most recent findings suggest that compounds in the peels may be the secret to the apple’s cancer-fighting nature.
