Coffee is one beverage considered as a life saver by many around the world. It is well known for brightening up a day, increasing productivity and as a mood booster. Coffee is often consumed at the start of a day, midday, in the evening and after dinner for better digestion. Its aroma, taste, role as a stimulant etc. have brought it up as one of the world’s most popular beverages. It has always been a big question mark to scientists whether coffee takes a toll on heart health of consumers. Fluctuating and contrasting opinions have arisen regarding effects of coffee – some say it causes harm, while some others say it is best in improving heart health and blood vessel function. To draw the right conclusion, studies were conducted on thousands of participants to establish the link between coffee and heart health. During study, participants were divided on the basis of their coffee consumption habits into 3 groups – those who drank one or fewer cups of coffee a day, those who drank between one and three cups of coffee per day and ones who drank more than three cups of coffee per day. Analysing the 3 groups at the end of the study, no particular changes were detected comparing measurements of arterial stiffness between the three groups. This proves that there are no substantial adverse effects of coffee consumption on heart health. Through this research, scientists aim to put an end to the all-time question of negative impacts of coffee drinking.
