You need more coffee beans than tea leafs to brew a cup of each.įollowing figure shows some positive and negative health effects of caffeine on your body: Fig.3 Positive and negative effects of caffeine on the human body Source Facts and figures!Įver wondered if people drink more coffee or tea? The following illustrations shows the percentage of Americans who prefer coffee or tea by age group in 2015:Įvery second 30.000 cups coffee are consumed, that is 946200000000 cups of coffee a year! Last but not least it must be said that a single cup of coffee contains more caffeine than a cup of tea. Tea doesn’t kick in like your coffee and you won’t feel low after few hours, while once your coffee effect diminishes, you will feel even more exhausted. Not only lasts theine longer in your body it also comes with other positive compounds that are missing in your daily coffee. Theanine has a stimulating effect while caffeine has an exciting impact on your body. Green tea contains additionally an amino acid analogue, theanine which bounds theine. While caffeine gets fully absorbed in our stomach after 20 to 40 minutes, theine needs 6 to 8 hours and gets absorbed mostly through our intestinal tract. Theine is bound to so called tanning agents which cause us to degrade theine slower than caffeine.
Caffeine and theine are bound to other chemical compounds and then released in our body. Smokers are able to degraded caffeine faster than pregnant women, newborns need more than 100 hours! Theine however is processed in a different way by our body. Furthermore, blocking the adenosine receptors will increase the level of dopamine in your brain, one of the main reasons why you feel even more awake. You might be exhausted and need to rest but make your body think you are top-fit which can be dangerous. Since caffeine has a similar structure it can attach to adenosines receptors and block them. One of its tasks in the body is to let you know when you get tired. Caffeine has a similar structure as adenosine, a messenger substance of your body. It is able to permeate the brain blood barrier and thus reach your brain directly. Once it’s in your blood caffeine will affect your physical processes. The maximum blood concentration is reached after 20 to 30 minutes, it doesn’t accumulate but gets degraded with a half-life of 4 to 6 hours. The moment you drink your cup of coffee caffeine enters your body and within five minutes it enters your blood. Caffeine quickly gets absorbed by the human body. Caffeine is the world most widely used drug and is found in over 60 different plants as cola nut, tea bush etc. Though both are the same molecule I will continue to use the terms caffeine and theine. We need to take on an overall view before answering this question. Does that mean both are absorbed and processed the same way? Fig.1 Chemical structure of caffeine - Source Fig.2 Chemical structure of theine- Sourceĭid anyone of you spot a difference? I hope you didn't spend too much time since there is no difference because caffeine and theine are the same chemical molecule. In addition to that we will see some facts and figures. Then we will discuss the positive and negative effects. Let's have a look at the chemical structure of caffeine and theine first. A friend of mine told me theine is the same as caffeine, another friend told me they are totally different. Many people swear by the positive and stimulating effect of coffee since it contains caffeine. What do you choose? Of course to wake up! There are many ways to become wide awake: take a cold shower, do your morning sports routine or take a cup of coffee or tea. You have two choices now: wake up or go back to sleep.
We are all familiar with the situation – the alarm clock goes off and you don’t want to wake up. Welcome my dear Steemian friends to another episode of Myth or Fact!
