Coffee, a delicate balance between pros and cons

Coffee is a popular drink, and the delicate balance between its benefits and disadvantages has attracted attention. Coffee contains stimulants such as caffeine, which can refresh the mind and improve work efficiency, but excessive drinking may cause side effects such as insomnia and anxiety. Coffee is also beneficial to health, such as anti-oxidation and reducing the risk of diabetes. When enjoying the pleasure brought by coffee, it should be consumed in moderation, pay attention to balance, and avoid over-dependence.

In the busy modern life, coffee has become a must-have drink for many people. A cup of coffee a day seems to have become the norm in urban life. Is drinking coffee good or bad for us? Is coffee suitable for everyone? Let's explore this topic in depth.

1. Refresh the mind : This is the most well-known effect of coffee. The caffeine in coffee can stimulate the central nervous system, improve attention and concentration, and make people more awake.
