What is caffeine?

Caffeine is a naturally occurring, flavorless chemical that acts as a stimulant to the central nervous system, and as a diuretic. Caffeine can also be synthetically produced.

In what foods is it found?

It appears naturally in coffee, tea and cocoa beans, and is added in small amounts to colas to enhance their flavor. It is also added to appetite suppressants, cold medicines and pain relievers.

Is it something my body needs to function properly?

No. In fact, some dietitians say children should consume as little as possible because it does act as an appetite suppressant, and may dull their appetite for foods they need to grow. Pregnant women are often advised to avoid caffeine as well. However, there is no health risk associated with moderate caffeine consumption. (Three 8-ounce cups of coffee a day is moderate. Ten cups of coffee is considered excessive.)

Excessive caffeine intake can lead to an increased heart rate, nausea, vomiting, heartburn, dehydration, anxiety, depression, difficulty sleeping, and tremors.

Is it really possible to be addicted to caffeine?

You bet. People who try to quit consuming caffeine cold-turkey are likely to experience headaches, irritability, nausea and other symptoms. Doctors say that if you want to you reduce the amount of caffeine you consume everyday, slow down gradually to avoid these withdrawal symptoms.
