Your health questions answered

To find the answers to some of the most common health questions we have, we turned to a book called "Your Health: What Works, What Doesn't" published by Reader's Digest.

The book consulted dozens of experts and culled through hundreds of studies to bring readers a definitive answer to controversial questions about diet, fitness, disease, and medicine.

This article was originally published by Businessinsider, who also did additional research to confirm findings.
