Too Much Coffee Bad For Heart Health?
If people drink a lot of coffee regularly, it seems to put their heart health at risk, as long-term heavy coffee consumption increases fats in the blood, which significantly increases the risk of cardiovascular disease, according to a recent study.
Regularly drinking six or more cups of coffee a day over a long period of time leads to a greatly increased risk of developing cardiovascular diseases, according to a study by researchers from the Australian Center for Precision Health at the University of South Australia . The study was published in the English-language journal “Clinical Nutrition” released.
Regardless of which form of coffee is consumed, for example black coffee, espresso or milk coffee, excessive consumption endangers heart health, the researchers report.
Coffee can increase lipids in the blood
High blood lipid levels are a well-known risk factor for heart disease, and since coffee beans contain the very potent cholesterol-increasing compound (cafestol), the research group has now investigated the possible links between blood lipid levels and coffee consumption. It was shown that long-term, heavy coffee consumption (six or more cups per day) the amount of lipids (fats) in the blood The researchers explain that this can increase the risk of cardiovascular disease.
It is also important that the established correlation is dose-dependent. In other words, the more coffee someone consumes, the greater the risk of developing cardiovascular diseases.
“There is a lot of scientific debate going on about the pros and cons of coffee, but while it may seem like we are on old terrain, it’s important to fully understand how one of the most widely consumed beverages in the world affects our health can ”, emphasizes the study author Professor Elina Hyppönen from the University of South Australia in one Press release.
Unfavorable lipid profile due to coffee consumption
“In this study, we examined genetic and phenotypic associations between coffee consumption and plasma lipid profiles – the cholesterols and Fats in the blood – and found causal evidence that habitual coffee consumption contributes to an unfavorable lipid profile, which can increase the risk of heart disease, ”explains the expert.
Filter and instant coffee healthier for the heart?
Cafestol is mainly found in unfiltered broths such as French press coffee and Turkish and Greek coffee, but also in espresso, which is the basis for many forms of coffee beverages such as cappuccino or latte macchiato, explains the team. Filter and instant coffee, on the other hand, contain very little or no caffestol, so these types of coffee are a good choice in terms of their effects on lipids, the researchers add.
The implications of this study are far-reaching. “In my opinion, it is particularly important for people with high cholesterol or people who are worried about having heart disease to choose carefully which type of coffee they drink,” says Hyppönen.
Filter coffee the better choice
The professor advises drinking filtered coffee and avoiding excessive consumption. Since coffee is so popular with many people, the consumption of coffee will always remain a controversial topic, according to the expert.
Keep coffee consumption in moderation
“Our research shows that excess coffee is clearly not good for cardiovascular health, which certainly has implications for those who are already at risk. As long as we don’t know otherwise, the tried and true adage applies – enjoy everything in moderation – when it comes to health, that’s generally good advice, ”adds Hyppönen. (as)
