Caffeine is the most important ingredient in coffee. Drinking coffee in moderation can stimulate the central nervous system and muscles, refresh the mind, restore muscle fatigue, promote blood circulation, dilate blood vessels and improve heart function. Drinking coffee can also help digestion, quickly consume body calories and break down fat. The polyphenols contained in coffee not only have antioxidant effect, but also have cardiovascular protection effect. Coffee has the function of promoting diuresis, which can help the human body to excrete metabolic waste in time.

Disadvantages:

Eating too much coffee can easily lead to osteoporosis, and it can also make people fidgety and excited, leading to insomnia.

Therefore, the most important thing to pay attention to when drinking coffee is whether caffeine is ingested too much. Just drink 1-2 cups a day.
