The world’s first genetic study which was conducted by the researchers of Australian Center for Precision Health at the University of South Australia has revealed that a long-term, heavy intake of coffee increases the risk of a person getting cardiovascular diseases (CVD’s) by 23 percent. This especially stands true for heavy drinkers who consume at least six cups of coffee per day. Such a high level of consumption will inevitably increase the risk of CVD, which is the leading cause for death in Australia, something which is a major concern for the health sector of Australia.
The lead for the research was taken by, Professor Elina Hyppönen, who said that the study mainly focused on the genetic and phenotypic link between coffee intake and plasma lipid profiles. Plasma lipid profiles are defined as the number of fats and cholesterol present in the bloodstream. The findings from the study concluded that people with a high level of coffee intake have weaker and much more harmful lipid profile, hence, this increases the risk of heart diseases in any one who consumes excess amounts of coffee.

In addition, the study also deduced that coffee beans have cholesterol-elevating compound in them, which is called cafestol. Cafestol is usually found in unfiltered coffees such as a French press, Turkish, Greek coffees, and espressos. In contrast, the researchers at the university also concluded that a much better option for people who are concerned regarding CVD is to consume filtered or instant coffee as opposed to unfiltered coffee.
Conversely, another such study was recently published, namely, Circulation: Heart Failure and the study deduced that drinking two or three coffee cups per day may lower the risk of heart failure by a significant 30 percent which is quite opposite to the aforementioned research. Moreover, Dr. Alan Barclay, a very well known dietitian and researcher who works at the University of Sydney, took both studies in to consideration and was able to come up with the conclusion that “A moderate intake is generally safe. People just need to be sensible about drinking a moderate amount of good quality coffee in the context of a healthy diet and don’t worry about it”, said Dr Barclay.
