Hey there, caffeinated colleagues! Spring showers bring May flowers, and this May, Java Joe is here to bring you a fresh cup of news with a side of hazelnut creamer. If you find yourself asking what kind of things are going on all around the world of coffee, look no further! Here’s the latest and greatest micro-news to go with your morning brews.


Three recent studies have been presented by the American College of Cardiology convention in Washington DC, showing that daily coffee consumption is associated with a lower risk of heart disease and irregular rhythms.

Consumption was also shown to be associated with improvements for those who already have existing heart disease. These three related studies create the largest combined analysis of coffee’s role in preventing and managing heart disease.


“Because coffee can quicken your heart rate, some people worry that drinking it could trigger or worsen certain heart issues,” Peter M. Kistler, lead author of the study, announced, “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.”

Study 1 involved 382,535 individuals with an average age of 57 who have no known heart disease. During the study, those who would report drinking 2-3 cups of coffee per day were shown to have a 10-15% lower risk of developing heart disease, compared to non-coffee drinkers. The risk of stroke was also the lowest in those who drank one cup a day. There was markedly less benefit to drinking more or less coffee, although the risk of stroke and heart-related death were lowest among those who drank one cup per day.

Study 2 involved 34,379 individuals who had some form of pre-existing heart disease at baseline. Participants in the study who regularly drank 2-3 cups of coffee per day were shown to have no higher risk of heart rhythm patterns. In addition, regular coffee consumption was linked to a lower risk of heart failure. For example, a coffee drinker with atrial fibrillation was shown to be 20% less likely to suffer heart failure than those who drink no coffee at all.

Study 3 explored the link between coffee and cardiovascular disease, whether participants drank instant or ground coffee, and caffeinated or decaf. During this study, the authors found that caffeinated coffee had the most favorable cardiovascular benefit, with decaffeinated coffee offering a reduced risk of cardiovascular disease- with the exception of heart failure, yet it provided no benefits against arrhythmia.

It’s worth noting that there were some limitations to the study- diet was not otherwise monitored or controlled, sugar and creamer were not factored in, and participants were predominantly white- thus additional research will be needed to determine if these findings extend to other populations. The results should be further validated in randomized trials.
