An Australian study showed that drinking 3 cups of coffee a day can increase human life.
According to this study, drinking two to three cups of coffee a day is associated with a longer life in addition to reducing the risk of cardiovascular disease.
Antioxidants in coffee beans can help reduce inflammation, improve insulin sensitivity, increase metabolism, inhibit fat absorption by the gut, and block receptors known to cause abnormal heart rhythms, according to the British Sun newspaper.
In this study, researchers looked at data from more than 382,000 people without known heart disease to see if drinking coffee played a role in heart disease or stroke over a 10-year follow-up.
They found that overall, drinking two to three cups of coffee a day was associated with the greatest benefit, meaning a 10 to 15 percent lower risk of coronary heart disease, heart failure, heart rhythm problems, or death from any cause.
According to them, the risk of stroke or heart-related death was lower among people who drank a cup of coffee a day. Researchers observed a U-shaped relationship with coffee consumption and new heart rhythm problems. The benefit was greatest among those who drank two to three cups of coffee per day and was least among those who drank less or less.
