Drinking coffee appears to help your heart and may extend your life. In new studies being presented at the upcoming American College of Cardiology’s Annual Scientific Session, Australian researchers analyzed data from a database of roughly 500,000 people about how much coffee they drank every day and then followed those people for 10 years. The researchers found that a magic number of two to three cups of coffee each day was associated with a 10 to 15 percent lower risk of developing heart disease, heart failure, heart rhythm issues or premature death. Even one cup of coffee per day lowered the risk of stroke and death. And while not providing as large of a heart benefit, drinking decaf coffee reduced the rates of many forms of cardiovascular disease. And even though coffee has been shown to raise your heart rate, causing some to worry that it could make heart problems worse, the study found that coffee was not associated with any harms, like heart rhythm problems.
