A New Study Suggests Drinking Espresso Coffee Might Lead to Heart Problems

The result of a previous study conducted at the American College of Cardiology's 71st Annual Scientific Session earlier this year indicated that consuming coffee specifically two to three cups per day—decreases your risk of heart disease and hazardous heart rhythms.

According to researchers, coffee beans contain over 100 bioactive chemicals, making them a healthy addition to your diet.

Coffee's benefits and drawbacks are frequently contested, but study researchers discovered that decaf coffee had no protective effects against incident arrhythmia. However, new research has looked into another coffee component that may be harmful to your heart.

Limiting the Consumption of Boiled Coffee

A new study published in a journal suggested that unfiltered boiled coffee is linked to an increase in serum total cholesterol (S-TC). This elevation in cholesterol can progress to artery obstruction, which can lead to cardiovascular diseases.

The author of the research stated that their findings for boiled coffee are the same as in the 1980s, indicating that results are generalizable. This backs up earlier health advice to limit boiled/plunger coffee consumption due to its ability to raise S-TC (serum total cholesterol).

Researchers evaluated various preparation methods for coffee, comprising boiled/plunger coffee, filtered coffee, and instant coffee, using questionnaire responses from 21,083 Norwegian people over the age of 40. Men consumed nearly five cups of coffee per day on an average scale, while women drank slightly under four.

Data showed a strong link with elevated cholesterol in those who drank unfiltered espresso more so in males than in women and those who consumed three to five cups of espresso per day were shown to be at heightened risk than those who drank none.

Drinking more than six cups of filtered coffee, on the other hand, was linked to a slight rise in cholesterol accumulation in women but not in males. However, neither men nor women were found to have a dose-response connection with instant coffee, implying that while cholesterol levels did rise, however, it was not linked to an increase in daily cups of coffee.

According to Tom Sanders, DSC, Ph.D., professor emeritus of nutrition and dietetics at King's College London, those who drink less than two cups of coffee a day shouldn't be too alarmed about the findings. However, if you are drinking more than three cups a day, you should be cautious about drinking too much coffee.
