foods that contain caffeine
Caffeine is found in products that contain coffee beans and cocoa beans, such as coffee and chocolate. Itâs also in tea leaves, kola nuts, guarana and yerba mate. Check the ingredient labels of your food; if anything contains one of these products, steer clear of it.
Other products, such as guarana, a Brazilian plant whose seeds are high in caffeine, and yerba mate, a South American herb used to make tea, are also natural sources of caffeine. These are increasing in popularity, and are being used more and more as food ingredients.
Soda, Energy Drinks and Other Beverages. Colas and energy drinks are obvious sources of caffeine, but many other beverages also contain a caffeine jolt. Pepper-type sodas and some brands of root beer, lemon-lime soda and fruit-flavored drink mixes contain caffeine -- as do most chocolate beverages.
Everyone knows you can find plenty of caffeine in regular coffee (80-150 milligrams in a 6-ounce cup of brewed coffee). But you might be surprised to find as much (or more) caffeine in energy drinks, sodas -- even gum and ice cream. Coffee-flavored frozen yogurt and ice cream is also suspect, with anywhere from 45 to 85 milligrams of caffeine per cup, depending on the brand.
