Science explains why apples keep the doctor away

January 20, 2010 In the study, researchers discovered that rats eating a diet high in pectin had increased amounts of certain bacteria that may improve intestinal health. They say that when apples are eaten regularly and over a prolonged period of time, these bacteria help produce fatty acids that provide ideal PH conditions for ensuring a beneficial balance of microorganisms.

Authors of the study say they now need to determine whether the findings in rats apply to humans.
