Coffee is generally considered as an energetic and stress relieving beverage. Considering the current lockdown situation, people are more likely to spend time in stress-relieving activities, and drinking coffee is one of them.
The worldwide consumption of coffee has been increased in this COVID-19 lockdown. Which is why scientists have come forward with a healthier version of making a coffee at home.
The European Journal of Preventive Cardiology, by the European Society of Cardiology (ESC), has published research that examines the coffee brewing method to make it more healthy for human health.
Dag S. Thelle from the University of Gothenburg, Sweden is the first author and lead researcher of this experiment. He says that this study reports strong evidence between brewing practices and how they prevent cardiac diseases and increase longevity.
He further explains that unfiltered coffee has certain ingredients that are much likely to cause an increase in LDL levels. But when you use a filter to remove these ingredients, the coffee becomes healthy which saves you from heart attacks and early death.
Coffee is considered the most popular and highly used beverage in the whole world. It is a stimulant which freshens up the mind. Nearly 30 years ago, Professor Thelle worked on another study where he reported that coffee and cholesterol level (LDL) increase in the blood is directly interrelated. That is why drinking coffee has hidden risks for cardiac health.
Many experiments helped to find the major culprit causing this effect. And eventually filtering the coffee helped to remove them without doing anything extra. Typically, one cup unfiltered coffee has 30 times higher concentration of these cholesterol-raising compounds as compared to a cup of filtered coffee.
Thelle says that we were not sure whether or not this link with cholesterol improves heart health and save a person from an early death. And it was an unethical thing to conduct experiments on people, making them drink coffee to know it. Hence, he came up with a large population-based experiment and after a few decades, they calculated the results.
From 1985 to 2003 nearly, 508,747 healthy Norwegian individuals between the ages of 20 and 79 enrolled in this study. They shared their details on coffee type and consumption habits via a questionnaire. Based on the data collected, certain variables that affected the coffee taking habits were accounted for further examination. These variables included smoking, alcohol, education status, higher, weight, cholesterol, physical activities, and blood pressure levels.
Within an average of 20 years, 46,341 participants from this study died. Among these deceased people, 12,621 were triggered by cardiac problems. And from these people, 6,202 deaths were directly caused by a heart attack.
It gives the impression that coffee consumption is a dangerous thing. But on the other side, drinking filtered coffee was reported to be good for health. People who consume filtered coffee are generally at a 15% lower risk of death than people who don’t drink coffee at all.
In an account of death by cardiovascular diseases, the risk was 12% less in men and 20% less in women, as compared to people who do not consume coffee.
Thelle explains these findings as people who take filtered coffee perform better than people who do not consume coffee at all. But it is not possible to explain to them any variable i.e. age, weight, lifestyle, etc. so there are high chances that it is not just an assumption but a truth.
Overall, taking filtered coffee is healthy for the body and it prevents early death by a heart attack and other cardiac problems. This research shows that it is mainly due to the cholesterol affecting the nature of using an unfiltered coffee. The researchers advise people to consume only the filtered brew for reducing the risk of heart diseases.
