Put down your apple and grab a packet of chips. No, don’t. That would be too extreme. But a study addressing an old wives’ tale hasn’t come up apples for apples. Researchers (University of Michigan) said people who eat an apple a day are a little more likely to keep the doctor away, but once they adjusted for all the other differences the effect disappeared. There was one marked benefit for the apple-eaters: they were less likely to have needed prescription medication in the past year.
