When you come to Australia for the first time, one of the most notable things is the large number of coffee places around the cities. Thus, you can start to understand why Australians are considered one of the biggest coffee lovers in the world. With no doubts the coffee culture is well widespread around the country, but how much people know about the harms and benefits of coffee?
The main chemical compound in coffee is the caffeine, which is responsible for the most effects of coffee intake. On average, around 5 cups of coffee per day is considered a moderate consumption, which will contain approximately 400 mg of caffeine. Caffeine intake can have some physical and mental effects, what can be considered a reason for its broad consumption.
It is believed that cancer can be triggered by constant irritation of body surfaces, such as skin, mouth and throat. This irritation can be caused by extremely hot water therefore people started to get concerned about hot drinks, like coffee. However, research indicate that there is no relation between coffee consumption and the development of cancer, actually it is in the other way around. According to recent researches, coffee drinking may reduce the risk of develop cancer in various body tissues, as liver, endometrium, brain and colon.

Moreover, coffee seems to have influence on sports performance. Coffee, more specifically caffeine, is used to improve the performance of athletes, especially in aerobic sports. Apparently, caffeine can affect the time to take some activities such as running and cycling as well as reduce muscle pain. Caffeine can increase the production of adrenaline, the hormone responsible for increase blood flow to the muscles and heart, and therefore improving sports performance.
Furthermore, coffee consumption is often associated with cardiovascular diseases. Recent studies suggest that there is no general association between moderate coffee intake and coronary heart disease (CHD), which is the most common type of heart disease and cause of heart attack. Indeed, regular consumption of moderate dosage of coffee can be linked with a lower risk of CDH, especially in women.
There are some other components found in coffee, besides the caffeine, which can raise the levels of “bad cholesterol”. However, those components are found only in unfiltered coffee. On the other hand, some evidence suggest that high coffee consumption may increase the blood homocysteine, which can be associated to cardiovascular disease.

One of the known effects of caffeine is the power to keep people alert while improving concentration. For these reason, coffee is largely consumed in situations such as night shifts and long distance driving. Researches based on brain mapping technology shows that caffeine is not connected to the dependence circuit in the brain, thus it cannot be considered an addictive drug. Some people may experience side effects when they stop to drink coffee suddenly, however these withdrawal symptoms are not grave and last for a short time. Furthermore, these effects can be avoided by stopping the intake slowly.
Even though some facts have already been proven, some further research is need in order to understand clearly all the effects that coffee and caffeine can cause in human body.
