HOW DO PEOPLE GET CAFFEINE?

In North America, most people get their caf- feine from coffee beverages. In other parts of the world, tea is more common. Soft drinks and medicines also contain caffeine, and so do some candies. Energy drinks also contain lots of caffeine.

In North America, 90 percent of adults con-

sume some amount of caffeine daily.

Different kinds of coffee contain differ- ent amounts of caffeine. In general, a serving of coffee contains somewhere between 40 and 100 milligrams of coffee. Dark roasts have less than light- er roasts because the roasting process reduces the beans’ caffeine content.
