What Are Some Foods and Drinks That Have Caffeine?

Some foods and drinks that contain caffeine are coffee, black and green tea, cola soft drinks, energy drinks and chocolate. Foods flavored with coffee or chocolate also typically contain caffeine. Other caffeinated soft drinks are Mountain Dew, Dr. Pepper and some root beers.

A 5-ounce cup of coffee has approximately 100 milligrams of caffeine, although the servings at popular coffeehouses may contain larger servings of 16 to 20 ounces and as much as 300 to 400 milligrams of caffeine. Even so-called "decaffeinated" coffee contains small amounts of caffeine. Five ounces of brewed black tea has about 30 to 80 milligrams of caffeine and a 12-ounce can of cola has about 35 milligrams of caffeine. Orange, root beer and cream-flavored sodas may also contain caffeine.

Caffeine occurs naturally in cocoa beans. The darker the chocolate, the higher the amount of caffeine it contains. While a standard milk chocolate bar has 9 milligrams of caffeine, a dark chocolate bar of the same size has twice that amount.

Foods that are flavored with chocolate or coffee, such as ice cream, frozen yogurt, chocolate milk and hot cocoa, contain varying amounts of caffeine. Some products, such as water, candy and gum, are infused with caffeine and marketed as energy foods and beverages.

Caffeine increases mental alertness, but can also cause headaches and anxiety and interfere with sleep patterns. It is generally considered safe for adults in moderate amounts of approximately 200 to 300 milligrams a day. Caffeine is mildly addictive, and some persons may experience symptoms of withdrawal when they stop drinking coffee or remove other caffeinated products from their diet.
