Coffee History
Coffee was first consumed in the ninth century, when it was discovered in the highlands of Ethiopia. From there, it spread to Egypt and Yemen, and by the 15th century, had reached Azerbaijan, Persia, Turkey, and northern Africa. From the Muslim world, coffee spread to Italy, then to the rest of Europe, to Indonesia, and finally to the Americas.
Caffeine is a substance that exists naturally in certain plants. It can also be produced synthetically and used as an additive in food products. It is a central nervous system stimulant and a diuretic.
- Caffeine is absorbed and distributed very quickly. After absorption, it passes into the brain.
- Caffeine does not accumulate in the bloodstream nor is it stored in the body. It is excreted in the urine many hours after it has been consumed.
- Caffeine will not reduce the effects of alcohol, although many people still believe a cup of coffee will "sober-up" an intoxicated person.
- Caffeine may be used as a treatment for migraine headaches and in relieving, for a short time, fatigue or drowsiness.
Caffeine is widely consumed. It is found naturally in the leaves, seeds, and fruits of more than 60 plants, including tea leaves, kola nuts, coffee, and cocoa beans. It is in coffee, tea, chocolate, cocoa and some colas. Caffeine is also frequently added to over-the-counter medications such as pain relievers, appetite suppressants, and cold medicines.
