caffeineWhat is the most important thing in our life? Family, kids, work or something else? It’s health, of course. Because if a person is healthy, the rest will come. And nowadays when health is tightly related to anything we eat and drink, we thoroughly examine our food and drinks on a daily basis.

As we already know, coffee occupies second place in the universe, after oil, as the most consumed goods. It is evident we are very interested in what we drink, that’s why caffeine content in a cup of coffee is one of the most discussed subjects in the society. Let’s analyze what is caffeine and what's it for?

Caffeine - is a bitter, white crystalline xanthine alkaloid that is a psychoactive stimulant drug. If in simple words, it’s a substance found in beans, leaves and fruit of some plants – tea, chocolate produced from coca beans and naturally coffee. It functions as a natural killer for bugs residing in plants and feeding there.

Caffeine has a stimulant effect on human nervous system which is expressed in hyperactivity and elevated mood. That’s why it’s not surprising that most people choose drinks with high caffeine content. It helps being always alerted and prevents from falling asleep when you have to stay awake.

But all we need to know whether its positive features are more numerous than its negative ones.I bet there is no person on the earth drinking coffee who didn’t question him/herself about the caffeine content in a cup at least once in a life time.

According to Bunker and McWilliams in J. Am. Diet. 74:28-32, 1979, a 7 oz cup of coffee has the following caffeine (mg) amounts:

Drip 115-175
Brewed, percolated 80-135
Instant 65-100
*Decaf, brewed 3-4
*Decaf, instant 2-3

The caffeine in a cup of coffee differs a little because it’s important to take into consideration the amount of coffee per water, the way it was brewed, roasted and the type of the coffee bean. Did you know that Arabica beans contain lesser caffeine than the Robusta ones? It’s one of the reasons why Arabica bean has higher rating in the coffee world than the Robusta one. Also the amount of caffeine varies with the type of roast – the lighter the roast, the higher its content of caffeine, and vice versa.

So how to decide when the content of caffeine we take with our daily dose of coffee is useful and when it harms our health?

The risk line is considered more than 300mg a day, however it all depends on the weight of a person and his/her individual caffeine tolerance. It’s commonly known that a bigger person has an easier reaction to large amounts of drink, food and caffeine, of course. Thus, what’s good for one can be bad for another.

So what’s the norm for caffeine in coffee for you? Take into consideration the tips I gave you above and your personal sensation when drinking coffee. It’s very important to do what is good for you namely and only you can say if this or that doze of caffeine of coffee is good for you. Also give yourself a respite from drinking coffee and take something different. These are good preventive measures for you to stay healthy, not to get addicted to coffee and never get tired of it. Enjoy!


*As you can see from the table, even decaffeinated coffee contains caffeine, though in lesser amounts than the usual drink. Therefore, we cannot reduce our daily caffeine content drinking lots of decaf – the result will be the same as when we drink a couple of usual cups of coffee.
