What is caffeine and what is it for?

Caffeine is a natural alkaloid obtained from coffee beans (most often), from tea leaves and cocoa beans. Many people think that caffeine can only be found in tea, coffee and energy drinks. However, it is true that it is found in many other products: chocolate, many medicines, cosmetics (against cellulite) and the like.

So let's see where it all has caffeine and how much:

* Analgesics (25-65 mg of caffeine)

* A cup of Turkish coffee (115 mg of caffeine)

* A cup of filter coffee (145 mg of caffeine)

* A cup of espresso coffee (100 mg of caffeine)

* A cup of instant coffee (85 mg of caffeine)

* A cup of iced tea (70 mg of caffeine)

* A cup of Indian tea (65 mg of caffeine)

* 2.5 dl Red Bull (80 mg caffeine, yes, only!)

* Coca Cola (38 mg caffeine)

* Coca Cola Light (38 mg of caffeine, hm so much about this being the "light"

version) * Pepsi Light (30 mg of caffeine).

One cup of coffee contains 0.15-0.20 g of caffeine, and the lethal dose is 10 g. So, don't worry, you would have to drink 50 cups of espresso on ex to make caffeine have a fatal effect.

The great popularity of caffeine is reflected in its ability to stimulate the central nervous system and the cardiovascular system. At the beginning, it slows down the work of the heart, and then it begins to have a direct effect on the heart muscle, which can lead to energetic, sharp heart contraction and unpleasant beating and arrhythmia, if you overdo it with caffeine. This is the "kick" that all of us, caffeine addicts, love and look for in our morning cup :)

Caffeine acts on the muscles by tightening them quickly, the reflexes become faster, but their relaxation is more difficult and slower. 15 minutes after drinking coffee, caffeine achieves its maximum effect in the circulation. Caffeine even has a stimulating effect on metabolism. Accelerates fat breakdown and increases energy consumption. It also has a pronounced diuretic effect. Caffeine also increases the concentration of HDL and LDL cholesterol. What is important is that it does not lead to a change in their relationship, so it cannot be considered harmful in people who have an increased risk of coronary heart disease and atherosclerosis.

Now you know why your favorite coffee works the way it does.
