Coughlin has been in the pool as long as she can remember, building the muscles and learning the discipline that would eventually lead her to 12 Olympic medals. All that time in the water whether in chlorinated pools or salty oceans, could potentially wreak havoc on other things, such as skin, hair and nails. "Eating well and taking care of your body is the No. 1 most important thing for good hair, good skin and good nails," Coughlin, 29, says.
