What do you think about sports drinks? There are more brands out there, targeting (or focusing on) women. Some have lots of sodium, calories and sugar. Others are low-calorie, and all claim to provide electrolytes lost after exercise.

WEDNESDAY, March 12 (HealthDay News) -- Dental erosion -- the loss of the teeth's protective enamel -- is on the increase in the United States, researchers say.

Amaechi, an associate professor of community dentistry at the University of Texas Health Science Center at San Antonio, said in a prepared statement.
