New Study Finds: Drinking Coffee is Associated With Living Longer

Drinking Coffee is Healthy

Coffee can also help lowering the risk of heart disease 

Good news for coffee lovers: it’s not all bad. According to new studies being presented at the American College of Cardiology’s 71st Annual Scientific Session, drinking two to three coffee cups a day is associated with greatest heart benefits, lower risk of heart disease and dangerous heart rhythms but also with living longer.

Researchers said the analyses—the largest to look at coffee’s potential role in heart disease and death—provide reassurance that coffee isn’t tied to new or worsening heart disease and may actually be heart protective.

“Because coffee can quicken heart rate, some people worry that drinking it could trigger or worsen certain heart issues. This is where general medical advice to stop drinking coffee may come from. But our data suggest that daily coffee intake shouldn’t be discouraged, but rather included as a part of a healthy diet for people with and without heart disease,” said Peter M. Kistler, MD, professor and head of arrhythmia research at the Alfred Hospital and Baker Heart Institute in Melbourne, Australia, and the study’s senior author. “We found coffee drinking had either a neutral effect—meaning that it did no harm—or was associated with benefits to heart health.”

Kistler and his team used data from over half a million people who were followed for at least 10 years. They looked at varying levels of coffee consumption ranging from up to a cup to more than six cups a day and the relationship with heart rhythm problems (arrhythmias); cardiovascular disease, including coronary artery disease, heart failure and stroke; and total and heart-related deaths among people both with and without cardiovascular disease.

In general, having two to three cups of coffee a day was associated with the greatest benefit, translating to a 10%-15% lower risk of developing coronary heart disease, heart failure, a heart rhythm problem, or dying for any reason. The risk of stroke or heart-related death was lowest among people who drank one cup of coffee a day. Researchers did observe a U-shaped relationship with coffee intake and new heart rhythm problems. The maximum benefit was seen among people drinking two to three cups of coffee a day with less benefit seen among those drinking more or less.
