Caffeine in coffee has a particularly strong bitter taste, which can stimulate the central nervous system, heart and respiratory system and help prevent cardiovascular and cerebrovascular diseases.
It can also stimulate sympathetic nerve, promote gastrointestinal secretion of gastric acid, and then have the effect of appetizing and helping food.
In addition, caffeine is a mild stimulant. Drinking coffee in moderation can improve the sensitivity and attention of human body, accelerate the metabolism of human body, improve the mental state and physical quality of human body, and thus eliminate fatigue.
In addition, caffeine can also promote renal function, expel excess sodium ions from the body, increase urine output, improve abdominal distension and edema, and help to lose weight.
However, it is worth noting that although drinking coffee has many benefits, you should drink it in moderation.
Excessive drinking of coffee will not only lead to calcium loss in the body, increase the risk of osteoporosis, but also consume B vitamins in the body and aggravate fatigue.
This is because B vitamins are related to the coordination of nerves and muscles, which can maintain the balance and stability of the nervous system. People who lack B vitamins are more likely to get tired.
