READING THE LABEL: From oil in Gatorade to the amount of caffeine and other stimulants in energy drinks, previously unnoticed ingredients are coming under scrutiny as health-conscious consumers demand more information about what they eat and drink.
HOW IT WORKS: The U.S. Food and Drug Administration reviews and approves most additives to food or drinks before they hit the marketplace. But others can bypass that process if they are deemed "generally recognized as safe" by the government or food companies and the experts they hire.
