15 Facts You Did Not Know about Caffeine

#15 Caffeine Is Actually White

If you thought that caffeine is the same color as coffee, then you are wrong. Although most caffeinated beverages have a dark color, caffeine is actually white. It is a crystalline substance and bitter in taste. This description matches cocaine in a lot of ways as well.

#14 Dark Roast Coffee Has Less Caffeine Than Light Roast Coffee 

Roasting reduces the amount of caffeine contained in the coffee beans. Green beans contain about 0.9%-2.6% caffeine and roasted coffee beans contain about 1.3%-2% caffeine. This difference is rather minute. The amount of coffee extracted depends more on the brewing method.

#13 Caffeine Can Be Found in 60 Different Plants 

Caffeine is not just found in coffee beans and tea leaves. This substance is also found in guarana. It has become especially popular due to its use in energy drinks.

#12 The Use of Caffeine Might Date Back to the Stone Age

At least that is what many anthropologists believe to be true. Coffee appeared in Africa in 6th century A.D. and was later introduced to Arabia. In China, the tea-drinking tradition dates as far back as 2700 BC. However, coffee appeared in Europe only in 1573.

#11 Caffeine Is the Most Popular Drug in the World

About 90% of Americans consume caffeine in some form. According to statistics, Americans consume as many as 45,000,000 cups of coffee a day.

#10 Caffeine Reaches All Tissues of the Body within Five Minutes

Consumed in liquid form, caffeine reaches all tissues of the body within five minutes. However, peak blood levels are reached in about 30 minutes. Under normal circumstances almost all ingested caffeine is metabolized.

#9 Consumption of Caffeine in Large Doses Can Affect Your Health

If you are a big fan of coffee, then you should definitely pay attention to the following facts. Consuming above 650 milligrams of caffeine a day, which is the equivalent of 8 or 9 average cups of coffee, can cause longer term health effects. This list includes chronic insomnia, persistent anxiety and depression, and stomach ulcers. Larger doses can also cause headaches, jitters, abnormally rapid heartbeat, convulsions, and delirium.

#8 Regular Use of Caffeine Can Cause Physical Dependence

If you think that caffeine is not a drug, then think again. Regular Use of more than 350 milligrams of caffeine a day causes physical dependence on the drug. An interruption of regular use will produce withdrawal symptoms, including severe headaches, irritability and tiredness. If you stop taking caffeine abruptly, you may have symptoms for a day or more. However, this rule generally does not apply to those who drink one or two cups of coffee a day. In this case it will be easier to quit.

#7 10 Grams of Caffeine Is Considered a Lethal Dose

The lowest known fatal dose to an adult has been 3,200 milligrams. However, this dose was administered intravenously by accident and not as a result of patient’s consumption of coffee. The fatal oral dose is in excess of 5,000 milligrams. This means that one has to drink about 40 strong cups of coffee taken in a very short space of time. It is hard to believe it is even possible.

#6 In Small Doses, Caffeine Has Positive Health Effects

Drinking 1-2 cups of coffee a day is harmless to your organism, unless you have some specific medical conditions. The substance has been known to have positive effects like increasing your ability to learn, comprehension, memory, reflexes, and thought clarity. Caffeine causes your brain to have a higher sense of alertness, improving your feeling of well-being and your mood.

The International Olympic Committee banned caffeine in Olympic competitions. This fact once again proves that caffeine is indeed a drug. It might not be a strong one, but it is still a performance enhancer and stimulator.

#4 Coffee Is the Second Most Traded Commodity in the World

The first one, as you might have already guessed is oil. It is estimated that 12,000 tons of caffeine is consumed every year. Considering the fact that 10 grams of caffeine is considered a lethal dose this would have been enough to kill a lot of people.

#3 Coffee Houses Were Once Banned in England

In 1675, the King of England banned coffee houses. He claimed they were places where people met to plot against him.

#2 The Origin of the Term “Cup of Joe”

There are several versions as to how this term actually came to being. The most popular one is that in 1913, during World War I, Josephus Daniels, Secretary of the U.S. Navy under President Woodrow Wilson, was looking to impose stricter moral standards on naval life, and banned alcohol. The sailors were not overly happy with this decision and used the term “cup of joe” as an insult to their commander. According to another version, the term comes from World War II because American soldiers, known as G.I. Joes, consumed huge amounts of coffee. The third version of the term’s origin is that it is as a shortened form of “a cup of jamoke,” which was a common reference to coffee, its being a compound of Java and Mocha.

#1 Caffeine Does Not Help You Sober Up

Research suggests that people only think caffeine helps them sober up. It is a kind of   self-deception.For instance, people who drink caffeine along with alcohol think they are OK behind the wheel. But the truth is that both reaction time and judgment remain impaired.
