Caffeine is a purine alkaloid, it is a psychostimulant; in nature, caffeine is found mainly in tea leaves, parts of the coffee tree, cocoa tree, mate, guarana, cola and some other plants. We use it as part of drinks, for example, one cup of natural coffee contains from 100 to 200 mg of caffeine, a cup of tea - from 30 to 70 mg, a glass of cola or up to 45 mg.

The effects of caffeine on the human body can be both positive and negative. The degree of its influence depends on many factors: age, type of higher nervous activity, state of health, as well as the dose of caffeine itself.

We all know that coffee is addictive, and that's not good. But you can’t say 100% that this is a bad product, and you need to completely abandon it. When drinking coffee, as well as other caffeine-containing drinks, the main thing is not to exceed a safe dose. For a healthy person, it is 1-2 cups per day.

So, if you feel good and remember to eat in moderation, enjoy your morning latte, Americano or espresso without any doubt!
