You might want to reconsider having that extra cup of coffee. Researchers from the Australian Center for Precision Health at the University of South Australia have conducted a study on the effects of drinking too much coffee, and the results aren’t looking promising.
Researchers found that that long-term, heavy coffee consumption, around six or more cups a day, can increase the number of lipids in your blood, which can lead to a significantly higher risk of cardiovascular disease (CVD).
We all love our #coffee, but drink too much and you could be in hot water, especially when it comes to heart health. @ACPreH1‘s

During the study, researchers looked at the genetic and phenotypic associations between coffee intake and plasma lipid profiles, which are the cholesterols and fats in your blood.
They found evidence that habitual coffee consumption contributes to an adverse lipid profile which can increase your risk of heart disease. High levels of blood lipids are a known risk factor for heart disease. Researchers also found that coffee beans contain cafestol, which is a very potent cholesterol-elevating compound.
According to Professor Elina Hyppönen, a researcher on the project, “Cafestol is mainly present in unfiltered brews, such as French press, Turkish and Greek coffees, but it’s also in espressos, which is the base for most barista-made coffees, including lattes and cappuccinos.”
Hyppönen also noted that filtered and instant coffee contains little to no cafestol, meaning those are a better choice for people worried about lipids and CDV.
“In my opinion, it is especially important for people with high cholesterol or who are worried about getting heart disease to carefully choose what type of coffee they drink,” Hyppönen added.
The study used data from 362,571 UK-based participants, aged 37-73 years. Researchers used a triangulation of phenotypic and genetic approaches to conducting a comprehensive analysis.
According to the World Health Organization, Cardiovascular diseases are the number 1 cause of death globally, taking an estimated 17.9 million lives each year.
