Did you know that drip coffee contains less caffeine than regular coffee?

A cup of popular brewed coffee contains 115 milligrams of caffeine, espresso (and coffee brewed in a percolator) contains about 80 milligrams, while instant coffee contains only 65 milligrams. Decaffeinated coffee is not complete without caffeine.

It's about 3 milligrams. A can of Coca-Cola contains about 45 mg of caffeine, Pepsi 38 mg, MountainDew 54 mg, and TAB47 mg. Tea contains about 40 milligrams of caffeine, while an ounce of chocolate contains about 20 milligrams.

Coffee is the world's most popular stimulant: four out of five Americans drink it, consuming more than 400 million cups a day. Per capita consumption in Scandinavian countries exceeds 12 kg. The coffee industry employs more than 2.5 million people, making it second only to oil in world business.

By using chlorinated hydrocarbon solvents to treat green coffee beans, caffeine can be removed from coffee. Instant coffee is built by assimilating ground and roasted coffee with hot water, followed by drying equipment and high pressure dehydration, leaving only coffee powder. Some coffee products use chicory (a wild flower plant), no flowers, dates, malt or barley as a substitute for coffee, which is a far cry from real coffee.

Although coffee trees are thought to have developed around the Red Sea since the 7th century, the 15th century Arab writer Shehadingben wrote in his book that Ethiopians enjoyed coffee as early as anyone can remember. By the 16th century, coffee trees were found everywhere in Arabian Yemen. After the Turkish envoy introduced it to the court of Louis XIV in 1669, Europeans soon got a taste of it. Several years later, the Netherlands introduced coffee to Java. In 1714, the Frenchman Deske stayed and planted a coffee tree on the island of Martinique. The cultivation of coffee soon spread to Brazil and Central America from France and Guiana. Today, coffee is grown in most parts of the world.

Coffee is the seed of a coffee tree, which produces about 1 kilogram (2 pounds) of coffee a year. There are more than 25 types of coffee, of which the top three commercial types are Robaster, Libby and Arabica, which account for 70% of the total output.

Caffeine increases the power of aspirin and other painkillers, which is why it exists in some drugs. Ironically, the decline of caffeine is also one of the most common causes of headaches. Women who drink two or more cups of coffee a day have an increased risk of osteoporosis. However, it can be offset by drinking milk or yogurt to replace the missing calcium. Many studies have found that high levels of caffeine can damage fertility and drinking during pregnancy can lead to preterm delivery or infant defects.
