Coffee is one of the most popular beverages in the world and for good reason! Not only does it help those of us who struggle to get out of bed in the morning to find the will to start the day, but for those avid coffee drinkers among us, the smell and taste are both warm and comforting, especially on those cold winter mornings.However, there has been much debate over the years about how much caffeine a person should really be drinking per day. Recently, a team of researchers conducted a study to find out whether the amount of cups of coffee a person consumes each day has any impact on the stiffening of a person’s arteries. And the results were rather surprising indeed.The study saw 8,000 people split into three categories; those who drink one cup or less a day, those who drink between 1 and 3 cups and those who drink more than 3. The participants then underwent MRI scans and infrared pulse wave tests and the results proved avid coffee addicts were no more at risk of their arteries stiffening than those who typically drink less than a cup per day, even after considering factors such as age, weight and their smoking status.Dr Kenneth Fung from Queen Mary University of London explained, “Whilst we can’t prove a causal link in this study, our researcher indicates coffee isn’t as bad for you as previous studies would suggest.”And if you're interested, click here to find out what your perfect coffee is according to your star sign.
