Whether coffee affects health is a topic of great concern to many people, and scientists have been debating it for many years. But so far, scientific research has not found conclusive evidence that moderate consumption of coffee is harmful to human health. Between 1970 and 1980, the results of this study were usually negative. Extensive media coverage makes people feel uneasy about the caffeine in their diet.

In the 1990s, due to a more rigorous and accurate testing process and a better understanding of other aspects, such as alcohol consumption, exercise habits and smoking, these studies have now been able to clarify some unresolved arguments in previous studies. In particular, it has provided a lot of new knowledge about caffeine and health.

Many studies have shown that caffeine is actually good for the human body in many ways. For example, coffee can stimulate athletes to create better results, and it is found that the moderate stimulation caused by coffee is conducive to many daily activities, such as relieving work stress, refreshing effect when preparing homework, and so on. Moderate consumption of coffee will not affect human health, but is a good pick-me-up drink, almost no side effects.

Know caffeine

Caffeine is a mild stimulant that contains less caffeine in our daily drinks such as tea, cocoa and chocolate. Caffeine is also found in carbohydrate drinks such as cola and some anesthetics. It can accelerate the metabolism of the human body and keep people clear-headed and sensitive. The refreshing effect of coffee is very popular.

Caffeine can stay inside the body for several hours, and the effect on the body is appropriate for each person. Some people will lose sleep after drinking coffee at night, while others will be nervous and overexcited if they drink too much coffee, but many people will not be affected at all.

Once we understand the body's response to caffeine, we can use it to meet our needs. Drinking a cup of delicious coffee before the exam or long-distance driving will certainly reduce fatigue.

The caffeine in coffee is insoluble in cold water, but easily soluble in hot water. It will stimulate the cerebral cortex, eliminate drowsiness, enhance the sense of touch and thinking and adjust the function of the heart, but also dilate kidney blood vessels, diuresis and so on. However, caffeine is not limited to coffee. Usually a cup of 100cc coffee contains caffeine 60~65mg, green tea has 200~300mg, black tea has 350~400mg, and cocoa has about 100mg. Excessive caffeine intake is prone to tinnitus, hyperfunction of the heart (the heart beats rapidly, the number of pulses increases), and the pulse is uneven, so you must drink coffee in moderation.

Health and caffeine

There is no data to show that caffeine or drinking coffee is harmful to your health. On the contrary, some studies have shown that caffeine is good for human health. People often ask: how much coffee is too much? In fact, it all depends on the individual's bearing capacity and habits.

A cup of coffee contains an average of 60 to 90 milligrams of caffeine, while the average human body consumes nearly 500 to 600 milligrams of caffeine a day without any side effects. Coffee, tea and Coca-Cola are not addictive. Although many people are used to drinking these drinks for a long time, they just like their taste and refreshing effect, and it's not difficult to really give up.

Pregnant women's metabolism is relatively slow, so they should drink less coffee. Unlike smoking or drinking, drinking coffee does not have adverse consequences on fetal development and weight.

In the United States, a nearly decade-long survey of 85000 nurses found that moderate coffee consumption was not associated with the incidence of heart disease, nor with a variety of high blood pressure diseases.

There is only one special way to make coffee that is bad for your health. In Scandinavia, according to tradition, people brew coffee for hours to extract more coffee oil from it. The coffee brewed in this way contains a lot of cholesterol and can easily lead to heart disease and cancer. The taste of this coffee is also very different from that of coffee prepared by other methods.
