The Food and Drug Administration said Monday that it was investigating foods that have added caffeine after Wrigley introduced a new caffeinated gum this week. A few products that have added caffeine:
— Wrigley Alert Energy Gum contains about 40 milligrams a piece, or the equivalent amount found in half a cup of coffee.
— Jelly Belly Extreme Sport Beans have 50 mg of caffeine in a 100-calorie pack.
— Arma Energy Snx markets chips, trail mix and other products that contain caffeine, including "chocolate caramel cookie caffeine mix."
— Wired Waffles sells caffeinated maple syrup and "energy waffles."
— Some varieties of Frito-Lay's Cracker Jack'd Power Bites are coated wafers that include two tablespoons of ground coffee.
— Kraft's Mio Energy "water enhancer" squirts caffeine and flavoring into water.
