Susan Bowerman, a sports dietitian and assistant director of the Center for Human Nutrition at the University of California, Los Angeles, said athletes including the Arizona Cardinals, the Anaheim Ducks, Tom Glavine of the New York Mets and Chicago Bears linebacker Lance Briggs use Pedialyte and similar products in lieu of Gatorade and other sports drinks, The Arizona Republic reported Wednesday.

"It's the migrants who drink it. Sometimes each one of them will take three or four bottles of different flavors, depending on how much money they have," Santana said. The rehydrating solutions help those seeking to cross the border on foot to stave off dehydration, the top cause of death in the desert.
