The many perks of coffee in our lives

Coffee is one of the most favourite and beloved drinks worldwide, for this reason it is considered to be a commodity. Around 25 million small-scale producers make a living growing this crop and over 2.25 billion cups are consumed every day worldwide. Therefore, we may wonder what has got us all so hooked to coffee? Let’s have a look at the science behind a good coffee brew its potential health benefits.

Energy Booster and Brain function improvement: thanks to “caffeine“, the main stimulant component of coffee, after you drink coffee this caffeine is absorbed by your system through the bloodstream and from there it goes right to the brain and here, caffeine inhibits the neurotransmitters adenosine and benzodiazepine which are believed to slow down the brain’s activity. By blocking these neurotransmitters caffeine boosts brain activity making us feel more energetic. Furthermore, studies have found that controlled caffeine consumption by means of coffee can also improve different areas of brain function such as enhancement of auditory vigilance, visual reaction, memory and overall cognitive function.


Protection against heart disease: it has been argued that caffeine increases blood pressure but this increase is very small. However, several studies, including one by the Sun Yat-sen University in China, have demonstrated that caffeine through habitual moderate coffee drinking is actually associated with a lower risk of Coronary Heart Disease (CHD) in women. It is important to note that the best coffee beans containing the most chemicals related to lowering the risks of CHD are robusta beans.


Protection against type-2 diabetes: several studies have claimed that those who consume a regular intake of coffee per day (6 cups) can actually lower the risk of developing type-2 diabetes. It is believed that the reason behind these facts is that coffee contains minerals, phytochemicals, and antioxidants which act against the manifestation of this disease. A study carried out by Harvard University showed that the risk of type II diabetes decreases by 9% for each daily cup of coffee consumed. Moreover, a further study at Harvard University showed that decreasing coffee consumption by as little as 1 coffee cup per day increases the risk of type-2 diabetes whereas those who drink more than 3 coffee cups can indeed reduces their chances of developing this disease by up to 50%.
