When we get tired, or when we just want something to drink, the word "coffee" pops up in our mind, and this kind of phenomenon is occurring all around the world, to all of today's people. But this matter of course can lead us into excessive intake of caffeine, or even unconscious addiction. So, through legal regulations like the food control system, modern people's excessive caffeine intake should be reduced right away, because it causes both mental, physical problems and can lead to undetectable addiction.
First, a caffeine can damage our mental, especially the central nervous system. Such as anxiety, sharpness, irritation, nervousness, various kinds of unstable mental states can be formed because caffeine serves as a stimulant, and furthermore if it gets worse, people would suffer from insomnia. But here's a pernicious problem. In this modern society, patients of diverse mental troubles are growing in number, and even normal people are meeting with those symptoms. From this point, we can recognize how difficult it is to notice that caffeine is the factor of psychological illnesses.
Another problem of excessive caffeine intake is physical troubles. Absorbed caffeine increases human's heartbeat and the BMR, so people could be suffered from pounding heart and blood vessel related diseases. Also, caffeine palpates gastric acid secretion and causes gastrointestinal troubles like maldigestion. If this kind of physical symptoms are detected, it means that it's a real time to be seriously alert about excessive caffeine intake.
Those mental and physical problems can bring this matter to the final point, caffeine addiction. If it grows into addiction, numerous and detrimental illnesses like muscle convulsions, emesis, arrhythmia, osteoporosis, cystitis, esophageal damage would be emerged in human body. This is undeniably fatal condition, but it's a critical problem that we cannot notice the seriousness of excessive caffeine intake, before this detectable addicted stage.
Recommended allowance level of one-day caffeine intake is 400mg, per each adult, and 125mg for teenagers. But only a cup of americano has minimum 160mg, maximum 300mg of caffeine. This is a shocking figures, but we should know that not only a coffee, but also chocolate, tea, energy drink, and so much foods and drinks are containing caffeine. By regulating legally, and by specific policy control, we should make a limitation of caffeine intake to prevent caffeine addiction being a extensive social problem in advance.
