What is caffeine?

Basically it is a psychoactive substance that stimulates the central nervous system. It is used recreationally to increase the levels of energy and enhance focus capacity, most common consumed as coffee, an infusion extracted from the coffee plant beans but also from soft drinks, tea or other caffeinated beverages.

Caffeine can be found in different quantities in seeds and fruits of more than 60 plants. Its content in coffee varies depending on the type of coffee bean, the method of preparation.

How finely the coffee is ground, the roasting process and the brewing method are also known to influence the amount of caffeine in the cup of coffee.

The roasting process diminishes the caffeine content in the coffee bean, so the longer it is roasted the less caffeine will have.

The brewing method is important because the longer the beans are exposed to water the more substance can be extracted from them.

A moderate amount of caffeine is considered to be between 200 and 300 milligrams (mg) per day. 90 percent of the world population uses it in one form or another.

In the U.S 80 percent of adult consume caffeinated products daily. The average caffeine intake is around 200 mg per day, which means about two cups of coffee or four sodas.

Caffeine in a cup of coffee

The amount of it in a single cup of coffee can range from 27 mg to 175 mg. Filtered coffee has the highest caffeine content, brewed coffee comes next and then instant coffee.

Decaffeinated coffee is not completely free of caffeine because the extraction process is not total, but the caffeine content is very small so it has practically no effect.

Excessive caffeine intake

Large amounts of this substance more than 300 mg per day may increase the chances of adverse reactions and can also lead to caffeinism, which is a condition that combines caffeine dependency with unpleasant physical and mental conditions.

Excessive use of caffeine can lead to nervousness, irritability, restlessness, insomnia, temporarily raised blood pressure, heart palpitations.
