1. What is Caffeine?
Caffeine is a stimulant naturally found in tea, coffee and cocoa plants. They work by stimulating the brain and central nervous system, keeping people awake and preventing fatigue. The Ethiopian shepherd was the first to discover this stimulant, noticing the additional energy it gives his goats. Today, more than three-quarters of the world's population consumes a product containing caffeine every day, and that number goes up to 90% among adults in North America.
Caffeine is a bitter white substance that occurs naturally in more than 60 plants, including coffee beans, tea leaves and cocoa pods (used to make chocolate). The US Food and Drug Administration (FDA) considers caffeine to be both a food additive and a medicine.
The most common sources of caffeine for most people are coffee, tea, soda, and chocolate. The amount of caffeine in foods and beverages varies. For coffee and tea, the amount of caffeine per cup depends on the brand, the type of beans or leaves used, how it's prepared and how long it is. Most sodas, not just cola, contain caffeine. Energy drinks are increasingly popular, especially among teenagers and young adults. The caffeine content in these drinks ranges from 60 mg to over 250 mg per serving.
