A recent study finds that those who drink around 25 cups of coffee in a day are still healthy and do not have to worry about any heart problems. Previous studies indicated that too much coffee consumption could stiffen the arteries because it puts sudden pressure on the arteries, and it increases the chances of a stroke or a heart attack.

However, research released by the British Heart Foundation found that drinking up to five cups of coffee in a day, even up to 25 cups, was still safe for the arteries as drinking one cup of coffee in a day.

This study was done on 8,000 participants all across the United Kingdom, and it was presented at a conference in Manchester. Scientists from QMUL or the Queen Mary University of London divided the participants into three different groups for this research.

The first batch drank one cup of coffee; the second drank between one to three cups while the third drank more than three cups of coffee. Some of the participants in the third group drank around 25 cups of coffee, and the experts found that there were no side effects like stiffening of the heart's arteries and they were as healthy as the hearts of those who drank one cup of coffee in a day. 

All of the people who participated in the research underwent heart scans and pulse wave tests; the results showed that everyone was healthy regardless of weight, age and smoking status. Dr Kenneth Fung, one of the doctors from QMUL, stated in an interview that even though coffee is popular worldwide, a misleading report can put coffee drinks off from enjoying it.

This is why releasing the results of their study is important to debunk all the previous studies suggesting that high consumption of coffee is not healthy. The associate medical director, Professor Metin Avkiran, from the British Heart Foundation, stated that the new research removes the potential side effects of too much coffee on your arteries.

The second research that was released at the same conference in Manchester found that those who were admitted to several hospitals with stroke and cardiac arrests at the weekend were not in the brink of dying compared to those who were admitted during weekdays. 

This research was led by doctors at Aston University and included around 4,000 people who went to the hospital because of cardiac arrest, and they were assessed that they would live for five more years.
