Dr. Cade studied University of Florida players suffering from heat-related injuries and dehydration. He developed a drink containing sodium, sugar, electrolytes, and lemon juice to replenish sweat and blood sugar levels. Initially tasting terrible, his wife suggested adding lemon juice, creating the drink called Gatorade. When first introduced to the team, few wanted to try it, but 10 players did over subsequent games and practices. Gatorade has remained much the same as the original recipe except for flavor variations.
