Regular apple intake is associated with all sorts of benefits, such as living longer and, more specifically, a lower risk of dying from cancer. At 0:17 in my video Apple Peels Put to the Test for Chronic Joint Pain, you can see the survival curve of elderly women. Of those who do not eat an apple a day, nearly a quarter had died after 10 years and nearly half were gone after 15 years. In comparison, those who eat on average about half an apple a day don’t die as young, and those eating one daily apple—more than three and a half daily ounces, which is around a cup of apple slices—lived even longer. Is it possible that people who eat apples every day just happen to practice other healthy behaviors, like exercising more or not smoking, and that’s why they’re living longer? The study controlled for obesity, smoking status, poverty, diseases, exercise, and more, so the researchers really could compare apples to apples (so to speak).
