How many cups of coffee pose a risk to heart health by raising cholesterol levels; Scientists answer and coffee lovers are intolerant.
In a groundbreaking genetic study, Researchers from the University of South Australia found that long-term and increased coffee consumption - that is, more than six cups a day- can increase the amount of lipids in the blood and therefore increase the risk of cardiovascular disease.
The most important, in fact, is that this correlation is positive and depends on the dosage, which means that the more coffee one drinks, the higher the risk of cardiovascular disease. The results of the study were published in Clinical Nutrition.
Scientists have been discussing the pros and cons of coffee extensively in recent years and have covered a considerable amount of ground with the data so far., but it is important to fully understand how one of the most consumed beverages in the world can affect our health.
To reach these conclusions, Well, the researchers used data from 362.571 participants in the British biobank, age 37-73 years, and performed a detailed analysis.
"In this study, We looked at the genetic and phenotypic correlations between coffee consumption and plasma lipid profiles - cholesterol and blood fats - finding evidence that regular coffee consumption contributes to an undesirable lipid profile that may increase the risk of heart disease., says Elina Hyppönen, a researcher at the University of South Australia and Professor:
"High levels of lipids in the blood are a known risk factor for heart disease and as coffee beans contain a very strong compound that can raise cholesterol., Cafestol, it was important to look at them in combination ".
Cafestol is mainly found in coffee varieties, such as French and Greek, but also in espresso. instead, there is little or no caffeine in filtered and instant coffee, therefore in terms of the effect on lipids, this category of coffee is considered better.
"The implications of this study are likely to be wide-ranging. In my opinion, It is especially important for people who have high cholesterol or are worried about heart disease to carefully choose the type of coffee they consume. ", concludes the specialist.
